MANAGING HIGH BLOOD SUGAR IS KEY TO REDUCING COVID-19 COMPLICATIONS: STUDY

MANAGING HIGH BLOOD SUGAR IS KEY TO REDUCING COVID-19 COMPLICATIONS: STUDY

By: Kara-Marie Hall, RN, BSN, CCRN

Key Takeaways:

  • Researchers at Michigan Medicine are using a targeted algorithm to help manage blood sugar levels in COVID-19 patients.
  • High blood sugar (hyperglycemia) is linked to severe illness in those with COVID-19. 
  • Having a severe case of COVID-19 can also cause high blood sugar in people who do not have diabetes.
  • Aggressive management of high blood sugar in patients with COVID-19 appears to reduce their risk of long-term health consequences associated with the virus.

Researchers at Michigan Medicine have created a management tool that could improve outcomes for patients with high blood sugar (hyperglycemia) and COVID-19. The research, which was published ahead of print on August 11 in the journal Diabetes, shows a two-way relationship between blood sugar levels and COVID-19.

According to the researchers, having high blood sugar can put patients at risk for more severe illness if they contract COVID-19. The reverse also appears to be true: patients with COVID-19 also are at risk for high blood sugar levels, even if they do not have diabetes.1

“Based on current evidence, it’s fair to say that the COVID-19 virus, particularly in its most severe forms, leads to much higher blood glucose levels,” study senior author Rodica Pop-Busui, MD, PhD, tells Verywell. Pop-Busui adds that having high blood glucose levels can also lead to worse outcomes for patients with COVID-19.

If left uncontrolled, the inflammation from COVID-19—often called a “cytokine storm”—can cause complications when coupled with inflammation caused by hyperglycemia.1 It also increases the likelihood of needing mechanical ventilation.

What Is Hyperglycemia?

Sugar (glucose) is necessary for proper organ function. Glucose enters your organs’ cells through a hormone called insulin. If the amount of glucose in your body exceeds the amount of insulin available, the glucose builds up in your blood and causes high blood sugar levels, known as hyperglycemia.

Hyperglycemia is typically defined as a blood sugar level of at least 180 mg/dl or greater when measured one to two hours after eating.2 However, the defined range varies among health organizations. Diabetes mellitus (type 1, type 2, and gestational) is the most common cause.

Michigan Medicine Introduces Hyperglycemia Management Teams

The researchers at Michigan Medicine designed a personalized, targeted clinical algorithm—a set of guidelines that helps healthcare providers make decisions—to help frontline healthcare workers without adding to their already heavy workload.

To put the guidelines into practice, the researchers launched several hyperglycemia management teams that were tasked with:

  • Checking patients’ glucose values through venous and arterial blood specimens rather than bedside glucose checks (because it’s more convenient)
  • Creating timely insulin dose adjustments multiple times a day
  • Reducing the number of glucose checks for most patients to every six hours

Not only did the algorithm lower patients’ glucose levels to an acceptable target range (generally 150-180 mg/dL), it also lessened the burden on frontline health care workers.

“We developed this early in the course of the pandemic, and we have continued to adapt and improve it based on lessons learned daily on the frontlines,” Pop-Busui says. “Others have started to use variations of this algorithm as well.”

What This Means For You:

If you have diabetes or even prediabetes, keeping your blood sugar levels well-controlled can help you reduce the risk of complications if you contract COVID-19.

COVID-19 Can Trigger Hyperglycemia

The Michigan Medicine researchers also found that some of the COVID-19 patients who had been referred to them for treatment developed high blood sugar levels even though they did not have diabetes.

“The severe inflammatory reaction triggers insulin resistance and high blood sugar even in people who may not have had known diabetes, but could have been in a prediabetic state,” Pop-Busui says.

A recent study published in the Journal of Medical Virology corroborates this idea, showing that out of 184 patients hospitalized with COVID-19, about 24% of patients were prediabetic.3

What is Prediabetes?

Prediabetes is a precursor to type 2 diabetes. According to the Centers for Disease Control and Prevention, more than 1 in 3 Americans have prediabetes. Over 84% of people with prediabetes are unaware that they have it.4

However, factors beyond diabetes and prediabetes can contribute to high blood sugar.

“[Patients with hyperglycemia] may also simply have stress hyperglycemia, which can occur from the stress of illness,” Roma Gianchandani, MD, another author of the Michigan Medicine study, tells Verywell,

Regardless of whether patients have prediabetes, diabetes, or stress hyperglycemia, Pop-Busui says their high blood sugar levels need immediate and sustained treatment.

Risks of Untreated Hyperglycemia

Romy Block, MD, an endocrinologist and co-founder of Vous Vitamin, tells Verywell that long-term, high blood sugars can directly injure blood vessels. Several health problems can result from this damage, including:

“In many medical conditions, tightly controlled sugars can decrease the duration of illness and decrease the [number of] days spent in the hospital,” Block says.

Treatment for hyperglycemia usually includes the administration of insulin—either given intravenously (directly into your vein) or under the skin—to bring down high blood sugar levels. 

BENIGN PROSTATE ENLARGEMENT

An enlarged prostate means the gland has grown bigger. Prostate enlargement happens to almost all men as they get older. An enlarged prostate is often called benign prostatic hyperplasia (BPH). It is not cancer, and it does not raise your risk for prostate cancer.

Age-associated prostate gland enlargement that can cause urination difficulty.

This type of prostate enlargement isn’t thought to be a precursor to prostate cancer.

With this condition, the urinary stream may be weak or stop and start. In some cases, it can lead to infection, bladder stones and reduced kidney function.

Treatments include medication that relaxes the bladder or shrinks the prostate, surgery and minimally invasive surgery.

Note:

  • Very common
  • More than 1.5 million cases per year (Nigeria)
  • Treatable by a medical professional
  • Requires a medical diagnosis
  • Lab tests or imaging often required
  • Chronic: can last for years or be lifelong

SYMPTOMS:

  • Frequent or urgent need to urinate.
  • Increased frequency of urination at night (nocturia)
  • Difficulty starting urination.
  • Weak urine stream or a stream that stops and starts.
  • Dribbling at the end of urination.
  • Inability to empty the bladder.

How do you check if your prostate is enlarged?

Diagnosis?

  • Digital rectal exam. The doctor inserts a finger into the rectum to check your prostate for enlargement.
  • Urine test. Analysing a sample of your urine can help rule out an infection or other conditions that can cause similar symptoms.
  • Blood test. …
  • Prostate-specific antigen (PSA) blood test.

 

TREATMENTS:

Treatment consists of supportive care and urinary retention medications

Treatments include medication that relaxes the bladder or shrinks the prostate, surgery and minimally invasive surgery.

Don’t resign yourself to living with BPH. Addressing your symptoms now can help you avoid problems later. Untreated BPH may lead to urinary tract infections, acute urinary retention (you can’t go at all), and kidney and bladder stones. In severe cases, it can lead to kidney damage.

Treatment options include medications and surgery. You and your doctor will consider several factors when you evaluate these choices. These factors include:

  • how much your symptoms interfere with your life
  • the size of your prostate
  • your age
  • your overall health
  • any other medical conditions

Can enlarged prostate Be Cured?

These are tablets that relax the muscles in the prostate and around the opening of the bladder, making it easier to urinate. They don’t cure an enlarged prostate, but they can help to relieve symptoms. Alpha-blockers are usually the first type of medicine you will be offered unless your prostate is very large.

Note Also:

If you have BPH or prostatitis, make an effort to reduce your caffeine intake by cutting back on coffee, soda or energy drinks. Avoiding caffeine can make a big difference in your urinary health. Another important drink for your prostate is water. Stay hydrated, and do not try to drink less to reduce your urine.

Various types of exercises can be helpful for men with prostate problems or OAB. Kegel exercises can strengthen and train your pelvic floor muscles to help control urination. Exercises such as walking, jogging, swimming, and tennis are also beneficial.

What foods hurt your prostate?

  • Red meat and processed meat. A diet high in meat, particularly if it’s cooked well-done, may be associated with an increased risk of developing prostate cancer. …
  • Dairy. Consuming large amounts of dairy products may increase your risk of developing prostate cancer. …
  • Alcohol. …
  • Saturated fats.

Green leafy vegetables are especially important because they are rich in antioxidants. Cruciferous vegetables such as broccoli also reduce the risk of prostate problems, including BPH and prostate cancer. People who eat onion and garlic regularly may also benefit from a lower risk of BPH.

Our Journey As Social Changer

Four years ago, we started this journey of impacting life based on the fearful life experience and research done by one of our founders who almost lost it all to high blood pressure (hypertension). It was not a palatable story, based on our finding that hypertension and diabetes are two non-communicable diseases that kill without signs or symptoms and which millions of Nigerians are battling. More than half of the numbers are not aware how deadly these ailments are. According to the World Health Organization (WHO), hypertension and diabetes are responsible for an estimated 45% of adults’ deaths due to heart diseases and 51% of deaths due to stroke globally. To end this surge, it has to start with you and me, and that is what we are doing at Rays of Hope Support Initiative: raising awareness, providing medical screening, health tips, medication and follow-up. We are asking you to join us and let us join hands in putting a stop to these silent killers.

IS WALKING A GOOD EXERCISE?

IS WALKING A GOOD EXERCISE?

Walking is great. It helps you clear your head; it keeps you active and it’s low-impact and joint-friendly. But is walking a good exercise? The short answer is yes, but like all things there is a skill to it. So, read on if you would like to find out more about the intricacies of walking!

Walking is your body’s natural movement. To count as exercise, you should aim to walk at a brisk pace for about 30 minutes, at least four times a week. Pay attention to your posture and footwear choices, and always warm up and cool down after your walks.

I’ll go through some of the benefits of including walks into your daily routine. You’ll also need some pointers on the kinds of shoes you should wear on your walks. On top of running, you can also add some other exercises to help increase your heart rate and burn calories.

Benefits Of Walking:

While many people wouldn’t don’t consider walking as exercise, it certainly benefits you in many ways, both physically and mentally.

Physical Condition

Walking at a moderate intensity for at least 30 minutes, five times a week is the minimum recommended amount of exercise. In particular, walking a longer distance at a faster pace will provide even more benefits.

People who walk regularly were found in a study to have a 31 percent decrease in their risk for cardiovascular diseases. 

Other benefits include:

  • The stress release from walking will help you sleep better.
  • Your overall health will improve as you lower your blood pressure and cholesterol.
  • Like any exercise, it helps you maintain muscle tone and bone density.

Walking will also help you burn some calories. Depending on your age and weight, a brisk 30-minute walk can help you burn an average of 129 more calories a day. If you’re also following a healthy diet, this can add up in the long run and help you lose weight.

Mental Wellbeing

If you take your walks as a moment to get in contact with yourself, you’ll get benefits that go far beyond the physical impact of the exercise. Exercise at even a moderate intensity can help reduce stress and anxiety and even improve cognitive function.

You can use walking to get an active start to your day and a moment to focus on your goals for the day. You can also take a walk at the end of the day to unwind and release stress.

How To Turn Walking Into Exercise:

Walking is a natural movement of your body. It’s low-impact and meditative and helps you crank up the steps on your Fitbit. If you don’t do any exercise, starting a walking habit will certainly be an improvement for your health.

It’s also a lot easier for your joints than running, especially if you’re overweight or have underlying problems. This is what makes it a good way to get active for beginners.

But for such a low impact, is it even exercise? 

Yes, if you do it correctly. 

While some may consider walking an inferior form of movement, it’s a good way to burn calories and add activity. However, walking as an exercise doesn’t mean peacefully strolling around. 

To be an effective exercise, walking needs to be brisk. This means you have to be a little winded and feel your heart rate going up. Your pace should be fast enough so that it would be hard for you to talk while you’re walking.

How Long Does It Take To Walk A Mile?

You should be able to walk a mile in fifteen minutes for it to count as brisk.

If you’re not able to do this at first, take your time and work on increasing your speed. Give yourself a goal to get a minute or 30 seconds out of your mile every time you go out. You’ll get to a 15-minute mile in no time.

Good Walking Form

The right form and speed are the most important things to get the biggest benefit out of your walks.

Warm up your muscles at a slower pace before starting and cool down after you’ve finished. Always stretch after your walks to maintain and increase your mobility. 

  • Back: Keep your back straight, your shoulders back and your head high—that means no looking at your phone!
  • Shoulders: Try to relax your shoulders and keep your arms slightly bent and swinging freely.
  • Breathing: Focus on your breathing correctly, taking profound inhales.
  • Feet: Try to walk as neutrally as possible, with your toes pointing forward. Land on the heel at first and then let your weight move naturally toward your toes.
  • Engage: Keep your core and your legs and glutes engaged.

Walking Equipment

Walking for exercise doesn’t require much equipment to be effective, but you may need to pay attention to your clothes and shoes. You can also invest in some poles to try out Nordic walking.

Comfortable Clothes

Make sure you’re wearing comfortable clothes that don’t inhibit your movement or cause other types of discomfort. Your regular workout clothes will be fine, as long as they’re stretchy and don’t have seams that will make you chafe.

Rather than wearing your regular comfy clothes, go for specific lightweight active wear. These offer protection from the elements while keeping you warm and will wick moisture away.

A Good Pair Of Shoes

Walking is free, but you might want to invest in the most basic piece of equipment before you get started: shoes. The right shoes are the most important thing to take into consideration when you’re starting a walking hobby. 

The first thing is to wear shoes that are made for exercise and are comfortable. They need to have enough support and cushioning to help you get through many miles of walking without injury.

Running Shoes Vs. Walking Shoes

Running shoes aren’t your best bet for walking practice. The two patterns of movement impact your foot differently, so you should give your foot the support it needs for the specific movement.

Running will impact your heels more as they’re the first point of contact with the ground. Walking puts more pressure on the middle of your foot. That’s why running shoes have more cushioning in the heel, whereas walking shoes usually focus more on arch support.

Finding Your Perfect Shoe

Depending on your previous underlying conditions, you might need to find a shoe that adapts specifically for them.

For example, people with flat feet need a little more support for the arch. If your arches are very high, you may need to balance them out to correct the alignment. This will help keep your ankles, knees and hips safe from unnecessary strain.

If you have plantar fasciitis, you may need more cushioning in the heel to keep it slightly elevated.

Spend some time figuring out whether you have flat or high arches or if your gait is neutral or if you tend to pronate. Then, make sure you’re wearing shoes that are right for you.

Nordic Walking Poles

Nordic walking can be helpful for people who are rehabilitating from injury. It can give some assistance in your upper body movement when walking and prevent your shoulders from curving forward. This is especially important for older adults.

Nordic walking also helps you burn more calories since it gets your whole body moving. You’ll be using 80–90 percent of your muscles by engaging the upper body instead of 50 with normal walking. This helps you burn up to 67 percent more calories every time you work out.

When you start with Nordic walking, make sure you’re using the right technique:

  1. The poles should be kept low, instead of ahead of your body.
  2. You should slightly swing your arms forward and back. 

Walking For Weight Loss

Walking can be very therapeutic and a great way to aid you in weight loss. Keep these pointers in mind to get the most out of your walking workouts.

Calories

The basic equation of weight loss is that the calories you ingest need to be lower than the calories you use in a day. Your calorie expenditure depends on many things, from your weight to your age and general activity level. 

According to Health Department guidelines, an adult woman would need around 1,600 to 2,400 calories per day. A man would need from 2,000 to 3,000 calories a day.

You can evaluate the calories you’ve burned with exercise with many apps or online calculators. Keep in mind that these are always rough estimates according to your body weight, as people have very different metabolisms.

Also, remember that weight loss is dependent on a healthy and balanced diet. Half an hour of walking won’t help you burn through hundreds of extra calories, so make sure your diet is in check.

Difficulty

Try to challenge yourself with your pace. Increase your velocity slowly when you get more comfortable.

Another way to increase the intensity of your walk is to choose a terrain you’re not as familiar with. Walking on the beach will add some real difficulty to your workout. Hiking up a hill will also help you burn extra calories and target your leg and glute muscles more.

Intervals

Doing intervals is also very beneficial for your weight loss goals and can help you improve your aerobic capacity faster. You could end up burning 20 percent more calories by simply changing your pace.

This is also great if you’re having a hard time keeping up with a faster pace for longer periods.

Try increasing your speed for a couple of minutes at a time and then relaxing it for another minute or two. It’s good if you can add these intervals to your walks a couple of times a week to really see improvements.

Treadmill Walking

If you’re walking indoors on a treadmill, you can easily make it more intense and add to the calorie burn. You can use different speeds and adaptable inclination to make your exercise more varied and interesting.

Try starting slow and gradually increase the inclination on the treadmill to a degree you can handle for a couple of minutes. Then go back, give yourself a breath, and repeat. You can also try some intervals at a higher speed.

Keep In Mind

One important thing before you head to the treadmill, however, is not to hold onto the supports. 

You’ll end up relying too much on them and even putting some of your weight on top of the handles. This will not only make the exercise less effective but will also affect your posture in the long run.

Keep your chin up and your arms swinging from side to side just like you would outdoors. If you need to grab the handles to give yourself a breath, only do it for a couple of seconds.

Curved Manual Treadmills

You might have seen the curved manual treadmills at your gym in recent years. They’re non-motorized, which means you move the treadmill with your steps. Since they’re concave, each step you take propels the movement of the treadmill.

What’s great about this device is that it significantly ups the intensity of your exercise. It helps reduce the impact on your joints, while at the same time making it harder for your muscles to keep up. You can also make it more difficult by turning on the resistance of the treadmill.

These kinds of treadmills can be a bit hard to master at first, especially with the balance. Ask a gym instructor for help, and lightly hold on to the railing until you’re sure you’re balanced.

Overall, a curve treadmill can be a nice addition to your walking routine. Try to switch it up between a normal treadmill and walking outside to avoid affecting your gait.

Other Exercises To Aid With Walking

Getting in some muscle-strengthening exercises will help you have more power in your legs and improve your endurance and speed. It will also help your general wellbeing and, if done correctly, keep you injury-free.

Another perk for building muscle is that it will help you burn more calories. While fat is more of a passive component, muscle needs calories to maintain density. This is why your body will burn more calories, even when resting when you have more muscle.

  • Legs: Do basic squats or lunges to improve the strength in your legs.
  • Upper body: You’ll need some strength in your shoulders to help balance out your walk and carry yourself with good form.
  • Core: Doing some back and ab work will help you keep your core better engaged when you’re walking.

You can even get in exercises in the middle of your walk to get your heart rate up. Try jumping or doing squats every so often to increase the difficulty. If there are stairs somewhere in your walking route, take advantage of them in your workout. 

How To Pass The Time While Walking

If being alone with your thoughts doesn’t sound appealing and you get bored easily, there are a couple of things you can do to pass the time.

Find A Friend

It can be easier to start a walking habit if you do it with someone else. Even if you walk at a pace that will make it harder for you to talk, the miles will pass faster when you’re with someone else.

You’ll also be more motivated and won’t want to let your walking buddy down, which helps for those inevitable days when you’re just not feeling up to it.

Change Your Routes

By changing your scenery, you may be able to ward off some boredom. Taking yourself outside of the city or even to a new neighbourhood makes things more interesting.

Listen To Music

Try listening to your favourite music to help you relax. Focus on the music and let it guide your breathing.

Music can even help you get more intensity out of your workout. How about creating a playlist that alternates between up-tempo and slower songs?

Find Podcasts and Audio books

If music doesn’t provide you enough distraction, try listening to a podcast or an audio book. Today, you have an incredible amount of podcasts to choose from, in every possible topic. You can learn a new language, gain new insights on health, business, or politics, or listen to comedians while you walk.

For those who struggle to find the time to read a book, try listening to them. Most bestsellers from fiction to non-fiction are now published in audio versions, so you have an amazing range to choose from.

If you’re walking on a treadmill, try not to use this time on your phone or watching shows on Netflix. You’ll keep your head down in an uncomfortable angle, and you might feel this in your neck later.

Focus On Breathing

If you’re naturally tense and need some help winding down, take a meditative approach on walking. Focus on your breath and try to clear your mind of all other thoughts. It can take some getting used to, but soon you’ll be able to disconnect and only focus on your body.

Ready, Set, Go

You’re just about ready to start your new walking habit to improve your health and overall wellbeing. You’ve got your shoes, your music, and your walking buddy with you. It’s time to get outside.

A minimum of 30 minutes four times a week will help you keep your blood pressure down and improve your heart health. Adding strengthening exercises and increasing the difficulty of your walks adds to the calorie burn and your overall fitness level.

Remember to keep your pace brisk and always stretch after your walk. Pay attention to your breathing and your form. Keep your shoulders down, your chin up and your arms swinging.

 

 

A BEGINNER’S GUIDE TO THE LOW GLYCEMIC DIET

A BEGINNER’S GUIDE TO THE LOW GLYCEMIC DIET

The low glycaemic (low GI) diet is based on the concept of the glycaemic index (GI).

Studies have shown that the low GI diet may result in weight loss, reduce blood sugar levels, and lower the risk of heart disease and type 2 diabetes.

However, the way it ranks foods has been criticized for being unreliable and failing to reflect foods’ overall healthiness.

This article provides a detailed review of the low GI diet, including what it is, how to follow it, and its benefits and drawbacks.

The low glycaemic (low GI) diet is based on the concept of the glycaemic index (GI).

Studies have shown that the low GI diet may result in weight loss, reduce blood sugar levels, and lower the risk of heart disease and type 2 diabetes.

However, the way it ranks foods has been criticized for being unreliable and failing to reflect foods’ overall healthiness.

This article provides a detailed review of the low GI diet, including what it is, how to follow it, and its benefits and drawbacks.

What is the glycaemic index (GI)?

Carbohydrates are found in breads, cereals, fruits, vegetables, and dairy products. They’re an essential part of a healthy diet.

When you eat any type of carb, your digestive system breaks it down into simple sugars that enter the bloodstream.

Not all carbs are the same, as different types have unique effects on blood sugar.

The glycaemic index (GI) is a measurement system that ranks foods according to their effect on your blood sugar levels. It was created in the early 1980s by Dr. David Jenkins, a Canadian professor (1Trusted Source).

The rates at which different foods raise blood sugar levels are ranked in comparison with the absorption of 50 grams of pure glucose. Pure glucose is used as a reference food and has a GI value of 100.

The three GI ratings are:

  • Low: 55 or fewer
  • Medium: 56–69
  • High: 70 or more

Foods with a low GI value are the preferred choice. They’re slowly digested and absorbed, causing a slower and smaller rise in blood sugar levels.

On the other hand, foods with a high GI value should be limited. They’re quickly digested and absorbed, resulting in a rapid rise and fall of blood sugar levels.

You can use this database to find the GI value (and glycemic load, described below) of common foods.

It’s important to note that foods are only assigned a GI value if they contain carbs. Hence, foods without carbs won’t be found on GI lists. Examples of these foods include:

  • beef
  • chicken
  • fish
  • eggs
  • herbs
  • spices

Factors that affect the GI of a food

A number of factors can influence the GI value of a food or meal, including:

  • The type of sugar it contains. There’s a misconception that all sugars have a high GI. The GI of sugar ranges from as low as 23 for fructose to up to 105 for maltose. Therefore, the GI of a food partly depends on the type of sugar it contains.
  • The structure of the starch. Starch is a carb comprising two molecules — amylose and amylopectin. Amylose is difficult to digest, whereas amylopectin is easily digested. Foods with a higher amylose content will have a lower GI (2Trusted Source).
  • How refined the carb is. Processing methods such as grinding and rolling disrupt amylose and amylopectin molecules, raising the GI. Generally speaking, the more processed a food is, the higher its GI (2Trusted Source).
  • Nutrient composition. Adding protein or fat to a meal can slow digestion and help reduce the glycaemic response to a meal (3Trusted Source4Trusted Source).
  • Cooking method. Preparation and cooking techniques can affect the GI too. Generally, the longer a food is cooked, the faster its sugars will be digested and absorbed, raising the GI.
  • Ripeness. Unripe fruit contains complex carbs that break down into sugars as the fruit ripens. The riper the fruit, the higher its GI. For example, an unripe banana has a GI of 30, whereas an overripe banana has a GI of 48 (5Trusted Source).

The amount of carbs is also important

The rate at which foods raise blood sugar levels depends on three factors: the types of carbs they contain, their nutrient composition, and the amount you eat.

However, the GI is a relative measure that doesn’t take into account the amount of food eaten. It’s often criticized for this reason (1Trusted Source).

To solve this, the glycemic load (GL) rating was developed.

The GL is a measure of how a carb affects blood sugar levels, taking both the type (GI) and quantity (grams per serving) into account.

Like the GI, the GL has three classifications:

  • Low: 10 or fewer
  • Medium: 11–19
  • High: 20 or more

The GI is still the most important factor to consider when following the low GI diet.

However, the Glycemic Index Foundation, an Australian nonprofit raising awareness about the low GI diet, recommends that people also monitor their GL and aim to keep their total daily GL under 100.

Otherwise, the easiest way to aim for a GL under 100 is to choose low GI foods when possible and consume them in moderation.

Low GI diet and diabetes

Diabetes is a complex disease that affects millions of people worldwide (6).

Those who have diabetes are unable to process sugars effectively, which can make it difficult to maintain healthy blood sugar levels.

However, good blood sugar control helps prevent and delay the onset of complications, including heart disease, stroke, and damage to the nerves and kidneys (7Trusted Source8Trusted Source9Trusted Source).

A number of studies suggest that low GI diets reduce blood sugar levels in people with diabetes (10Trusted Source1112Trusted Source).

A 2019 review of 54 studies concluded that low GI diets reduced haemoglobin A1C (a long-term marker of blood sugar control), body weight, and fasting blood sugar levels in people with prediabetes or diabetes (12Trusted Source).

What’s more, some research has linked high GI diets with a greater risk of developing type 2 diabetes. One study in over 205,000 people found that those with the highest GI diets had up to a 33% greater risk of developing type 2 diabetes than those who consumed the lowest GI diets (13Trusted Source).

A systematic review of 24 studies reported that for every 5 GI points, the risk of developing type 2 diabetes increased by 8% (14).

The low GI diet may also improve pregnancy outcomes in women with gestational diabetes, a form of diabetes that occurs during pregnancy.

Moreover, the low GI diet has been shown to reduce the risk of macrosomia by 73%. This is a condition in which newborns have a birth weight over 8 pounds and 13 ounces, and it’s associated with numerous short- and long-term complications for the mother and baby (15Trusted Source).

Other benefits

Studies have shown that the low GI diet may also have other health benefits:

  • Improved cholesterol levels. One study showed that low GI diets reduce total cholesterol by 9.6% and LDL (bad) cholesterol by 8.6%. LDL cholesterol is also associated with an increased risk of heart disease and stroke (1617Trusted Source1819).
  • May help you lose weight. Some evidence suggests that low GI diets can promote fat loss. However, more research is needed to determine whether low GI diets are effective for long-term weight loss (1620Trusted Source21Trusted Source).
  • May reduce the risk of cancer. Some studies suggest that people who consume high GI diets are more likely to develop certain types of cancer, including endometrial, colorectal, and breast cancer, compared with people on low GI diets (22Trusted Source2324Trusted Source).
  • May reduce the risk of heart disease. Recent research has strongly associated high GI and GL diets with an increased risk of heart disease (24Trusted Source25Trusted Source).

Foods to eat on the low GI diet

There’s no need to count calories or track your protein, fat, or carbs on the low GI diet.

Instead, the low GI diet involves swapping high GI foods for low GI alternatives.

There are plenty of healthy and nutritious foods to choose from. You should build your diet around the following low GI foods:

  • Bread: whole grain, multigrain, rye, sourdough
  • Breakfast cereals: steel cut oats, bran flakes
  • Fruit: apples, strawberries, apricots, peaches, plums, pears, kiwi, tomatoes, and more
  • Vegetables: carrots, broccoli, cauliflower, celery, zucchini, and more
  • Starchy vegetables: sweet potatoes with an orange flesh, corn, yams, winter squash
  • Legumes: lentils, chickpeas, baked beans, butter beans, kidney beans, and more
  • Pasta and noodles: pasta, soba noodles, vermicelli noodles, rice noodles
  • Rice: basmati, Doongara, long grain, brown
  • Grains: quinoa, barley, pearl couscous, buckwheat, freekeh, semolina
  • Dairy and dairy replacements: milk, cheese, yogurt, coconut milk, soy milk, almond milk

The following foods contain few or no carbs and therefore don’t have a GI value. These foods can be included as part of the low GI diet:

  • Fish and seafood: including salmon, trout, tuna, sardines, and prawns

Drawbacks of the low GI diet

Although the low GI diet has several benefits, it also has a number of drawbacks.

First, the GI doesn’t provide a complete nutritional picture. It’s important to also consider the fatproteinsugar, and fiber contents of a food, regardless of its GI.

For example, the GI of frozen french fries is 75. Some varieties of baked potato, a healthier alternative, have a GI of 93 or more.

In fact, there are many unhealthy low GI foods, such as a Twix bar (GI 44) and ice cream (GI 27–55 for low fat versions).

Another drawback is that the GI measures the effect of a single food on blood sugar levels. However, most foods are consumed as part of a larger mixed meal, making the GI difficult to predict in these circumstances (26).

Lastly, as mentioned earlier, the GI doesn’t take into account the number of carbs you eat. However, this is an important factor in determining their effect on your blood sugar levels.

For example, watermelon has a high GI of 72–80 and therefore wouldn’t be considered the best option when following a low GI diet.

However, watermelon also has a low carb content, containing under 8 grams of carbs per 100 grams. In fact, a typical serving of watermelon has a low GL of 4–5 and a minimal effect on blood sugar levels (27Trusted Source).

This highlights that using GI in isolation may not always be the best predictor of blood sugar levels. It’s important to also consider the carb content and GL of a food.

The bottom line

The low glycemic (low GI) diet involves swapping high GI foods for low GI alternatives.

It has a number of potential health benefits, including reducing blood sugar levels, aiding weight loss, and lowering your risk of heart disease and type 2 diabetes.

However, the diet also has multiple drawbacks.

At the end of the day, it’s important to consume a healthy, balanced diet based on a variety of whole and unprocessed foods, regardless of their GI.
