14 Low GI Foods for a Healthier Diet

14 Low GI Foods for a Healthier Diet

Diet trends may come and go, but a low-GI diet remains one of the few that has been shown to include benefits based on science. Low GI foods provide substantial health benefits over those with a high index, and they are key to maintaining a healthy weight.

What is GI? Glycemic index (GI) is the rate at which the carbohydrate content of a food is broken down into glucose and absorbed from the gut into the blood. When you eat foods containing carbohydrates, your body breaks them down into glucose, which is then absorbed into your bloodstream.[1]

The higher the GI of a food, the faster it will be broken down and cause your blood glucose (sugar) to rise. Foods with a high GI rating are digested very quickly and cause your blood sugar to spike. This is why it’s advisable to stick to low GI foods as much as possible, as the carbohydrate content of low GI foods will be digested slowly, allowing a more gradual rise in blood glucose levels.

Foods with a GI scale rating of 70 or more are considered to be high GI. Foods with a rating of 55 or below are considered low GI foods.

It’s important to note that the glycemic index of a food doesn’t factor in the quantity that you eat. For example, although watermelon has a high glycemic index, the water and fiber content of a standard serving of water means it won’t have a significant impact on your blood sugar.

Like watermelon, some high GI foods (such as baked potatoes) are high in nutrients. And some low GI foods (such as corn chips) contain high amounts of trans fats.

In most cases, however, the GI is an important means of gauging the right foods for a healthy diet.

Eating mainly low GI foods every day helps to provide your body with a slow, continuous supply of energy. The carbohydrates in low GI foods is digested slowly, so you feel satisfied for longer. This means you’ll be less likely to suffer from fluctuating sugar levels that can lead to cravings and snacking.

Let’s continue with some of the best examples of low GI foods.

1. Quinoa

GI: 53

Quinoa has a slightly higher GI than rice or barley, but it contains a much higher proportion of protein. If you don’t get enough protein from the rest of your diet, quinoa could help. It’s technically a seed, so it’s also high in fiber–again, more than most grains. It’s also gluten-free, which makes it excellent for those with Celiac disease or gluten intolerance.

2. Brown Rice (Steamed)

GI: 50

Versatile and satisfying, brown rice is one of the best low GI foods and is a staple for many dishes around the world. It’s whole rice from which only the husk (the outermost layer) is removed, so it’s a great source of fiber. In fact, brown rice has been shown to help lower cholesterol, improve digestive function, promote fullness, and may even help prevent the formation of blood clots. Just remember to always choose brown over white!

3. Corn on the Cob

GI: 48

Although it tastes sweet, corn on the cob is a good source of slow-burning energy (and one of the tastiest low GI foods). It’s also a good plant source of Vitamin B12, folic acid, and iron, all of which are required for the healthy production of red blood cells in the body. It’s healthiest when eaten without butter and salt!

4. Bananas

GI: 47

Bananas are a superfood in many ways. They’re rich in potassium and manganese and contain a good amount of vitamin C. Their low GI rating means they’re great for replenishing your fuel stores after a workout.

They are easy to add to smoothies, cereal, or kept on your desk for a quick snack. The less ripe they are, the lower the sugar content is! As one of the best low GI foods, it’s a great addition to any daily diet.

5. Bran Cereal

GI: 43

Bran is famous for being one of the highest cereal sources of fiber. It’s also rich in a huge range of nutrients: calcium, folic acid, iron, magnesium, and a host of B vitamins. Although bran may not be to everyone’s tastes, it can easily be added to other cereals to boost the fiber content and lower the overall GI rating.

6. Natural Muesli

GI: 40

Muesli–when made with unsweetened rolled oats, nuts, dried fruit, and other sugar-free ingredients–is one of the healthiest ways to start the day. It’s also very easy to make at home with a variety of other low GI foods. Add yogurt and fresh fruit for a nourishing, energy-packed breakfast.

7. Apples

GI: 40

Apple skin is a great source of pectin, an important prebiotic that helps to feed the good bacteria in your gut. Apples are also high in polyphenols, which function as antioxidants, and contain a good amount of vitamin C. They are best eaten raw with the skin on! Apples are one of a number of fruits[2] that have a low glycemic index. Be careful which fruits you choose, as many have a large amount of natural sugars[3].

8. Apricots

GI: 30

Apricots provide both fiber and potassium, which make them an ideal snack for both athletes and anyone trying to keep sugar cravings at bay. They’re also a source of antioxidants and a range of minerals.

Apricots can be added to salads, cereals, or eaten as part of a healthy mix with nuts at any time of the day.

9. Kidney Beans

GI: 29

Kidney beans and other legumes provide a substantial serving of plant-based protein, so they can be used in lots of vegetarian dishes if you’re looking to adopt a plant-based diet[4]. They’re also packed with fiber and a variety of minerals, vitamins, antioxidants, and other beneficial plant compounds. They are great in soups, stews, or with (whole grain) tacos.

10. Barley

GI: 22

Barley is a cereal grain that can be eaten in lots of ways. It’s an excellent source of B vitamins, including niacin, thiamin, and pyridoxine (vitamin B-6), fiber, molybdenum, manganese, and selenium. It also contains beta-glucans, a type of fiber that can support gut health and has been shown to reduce appetite and food intake.

Please note that barley does contain gluten, which makes it unsuitable for anyone who is Celiac[5] or who follows a gluten-free diet. In this case, gluten-free alternatives might include quinoa, buckwheat, or millet.

11. Raw Nuts

GI: 20

Most nuts have a low GI of between 0 and 20, with cashews slightly higher at around 22. Nuts, as one of the best low GI foods, are a crucial part of the Mediterranean diet[6] and are really the perfect snack: they’re a source of plant-based protein, high in fiber, and contain healthy fats. Add them to smoothies and salads to boost the nutritional content. Try to avoid roasted and salted nuts, as these are made with large amounts of added salt and (usually) trans fats.

12. Carrots

GI: 16

Raw carrots are not only a delicious low GI vegetable, but they really do help your vision! They contain vitamin A (beta carotene) and a host of antioxidants. They’re also low-calorie and high in fiber, and they contain good amounts of vitamin K1, potassium, and antioxidants. Carrots are great for those monitoring their weight as they’ve been linked to lower cholesterol levels.

13. Greek Yogurt

GI: 12

Unsweetened Greek yogurt is not only low GI, but it’s an excellent source of calcium and probiotics, as well. Probiotics help to keep your gut microbiome in balance and support your overall digestive health and immune function. Greek yogurt makes a healthy breakfast, snack, dessert, or a replacement for dip. The most common probiotic strains found in yogurt are Streptococcus thermophilus[7] (found naturally in yogurt) and Lactobacillus acidophilus[8] (which is often added by the manufacturer). You can also look into probiotic supplements for improving your gut health.

14. Hummus

GI: 6

When made the traditional way from chickpeas and tahini, hummus is a fantastic, low-GI dish. It’s a staple in many Middle Eastern countries and can be eaten with almost any savory meal. Full of fiber to maintain satiety and feed your good gut bacteria, hummus is great paired with freshly-chopped vegetables, such as carrots and celery.

Bottom Line

If you’re looking to eat healthier or simply cut down on snacking throughout the day, eating low GI foods is a great way to get started. Choose any of the above foods for a healthy addition to your daily diet and start feeling better for longer.

13 Best Foods to Eat at Night (Advice From a Health Coach)

13 Best Foods to Eat at Night (Advice From a Health Coach)

We’ve all had late-night cravings. Those times when you would lie in bed but your mind is on the fridge. You try to fight it, but you find out that you can’t. Food—you want food—to chew and to drink and to swallow. It usually goes this way: after much hesitation, you would get off your bed and walk over to the kitchen where you would stand for seconds and maybe even minutes contemplating a lot of things.

You have heard about it—read about it, too—the famous “eating late at night isn’t good for you.” You know well about how eating late at night can cause you stress and make you gain weight. But you just want to eat—and eat you must.

But what must you eat? What are your best and most healthy options? Here are the 13 best foods to eat at night.

1. Turkey

If you aren’t a vegetarian, then you most probably love turkey. It is not only very tasty and delicious, but it is quite nutritious, too. Turkey contains a lot of protein. As little as 28 grams of turkey already contains eight grams of protein.[1]

It also contains some amount of vitamins and a nutritive compound called selenium. Selenium is a powerful antioxidant that plays an important role in ensuring the thyroid gland functions properly.

Turkey passes as one of the best foods to eat at night because the protein tryptophan, which it contains in a considerable amount, is believed to promote tiredness and thus, sleepiness.[2]

2. Fish

Another great choice for non-vegetarians is fish, especially fatty fishes like salmon, tuna, and mackerel. These are considered healthy choices because they contain a considerable amount of Vitamin D. Vitamin D helps your body regulate its calcium levels and is good for your kidneys, parathyroid glands, skin, etc.

Fatty fishes also contain omega-3 fatty acids. Omega-3 fatty acids are a group of healthy fatty acids that can serve as anti-inflammatory agents and are good for the brain. Omega-3 fatty acids are shown to be able to increase the amount of serotonin produced by the nervous system, and thus, make sleep feel better.[3] This means that fishes would not keep you awake! You don’t have to roll from side to side trying to fall asleep after eating them.

Fishes also contain nutritive oils that are good for your body and skin.

3. White Rice

White rice is just rice that has no bran germ—that is, both bran and germ have to be removed as a result of processing from brown rice to make it white rice. This removal of bran and germ causes white rice to contain lower fiber, nutrients, and antioxidants when compared with brown rice. However, white rice still contains a commendable amount of nutrients such as thiamine, folate, and manganese and so is great as a late-night meal.

White rice has a high Glycemic Index. (GI). A food’s glycemic index is simply the measure of the rate at which that food increases the body’s sugar level. Taking in foods with a GI index, such as rice, can improve the quality of one’s sleep. This is as long as one takes these foods one hour before sleep. If you plan to sleep by 7 p.m, then it is a good idea to eat white rice by 6.p.m.[4]

4. Bananas

Finally, Something for vegetarians. A fruit! Bananas not only taste good, but they are also rich in the compounds potassium and tryptophan, making them one of the best foods to eat at night.

Tryptophan, as earlier stated, is an essential protein that plays a role in relaxation. Some bananas before meals can improve the quality of your sleep. Plus, they contain vitamins and are rich in antioxidants. They also contain compounds that are capable of making bowel movements easier.

5. Cheese and Crackers

Cheese and crackers, crackers being a source of carbohydrates and cheese a source of tryptophan, can help balance the body’s sugar level. When you take cheese and crackers together, more tryptophan is made available to your brain.[5] The sugar in cheese feeds your brain, and tryptophan helps with the production of melatonin.

This means that there would be more serotonin and melatonin production in your nervous system when you take cheese and crackers together. Serotonin improves the quality of a person’s sleep.

6. Warm Cereals

Cereals are great sources of fiber. Ones like oats also contain an impressive amount of melatonin, which improves sleep.

Before bed, a hot bowl of cereal and maybe even whole grains are a good choice. They do not contain a lot of calories and would most likely not keep you awake.

7. Yoghurt

Yogurt tastes good, and kids and adults love them. They are also a rich source of calcium. Calcium is an essential mineral to the body. It is necessary for the growth of bone and teeth, and skeletal, smooth, and cardiac muscles need it for muscular contractions to happen.

Your body also needs calcium to produce melatonin from tryptophan. If calcium levels are low, there will be a reduced rate of production of melatonin—and thus, low quality sleep. Yogurt also contains casein. Casein is believed to reduce early morning hunger.

Unsweetened yogurt is a great snack and one of the best foods to eat at night.

8. Eggs

Eggs are great sources of protein and don’t contain many calories. As a late-night snack, eggs are a great pick. They are easy to cook and can go along with many different kinds of snacks.

Eggs also contain tryptophan, which—as you must now already know—can improve the quality of one’s sleep.

9. Protein-Pineapple Smoothie

As you may have noticed, most of the snacks and foods on this list of best foods to eat at night are protein-rich foods. Protein-rich meals taken around bedtime can boost muscle repair. They can also combat age-related muscle mass loss especially in people who frequently exercise.

As a late-night snack, you can blend some pineapple pieces into milk. Milk is a great source of the protein tryptophan from which the body produces melatonin. Pineapples do not contain a lot of calories and might not prove a threat to your body’s normal digestive functions. Pineapples can also boost your body’s serotonin levels.[6]

10. Tart Cherries

Juices made from tart cherries are great alongside other snacks, such as crackers and cheese. Tart cherries have anti-inflammatory effects. Even though in small quantities, tart cherries contain the sleep hormone melatonin. They also contain procyanidin B-2, which is believed to keep stable the essential amino acid tryptophan.[7]

Tart Cherries have low calories, too. This means that they are not too heavy and do not pose the threat of fat deposition, and they would not keep you awake.

11. Honey

Honey harvested from bees is nutritious and does not contain a lot of calories. It is known to be capable of increasing the production of melatonin in one’s body.[8]

It also contains healthy sugars, such as fructose and glucose, and can have a healthy effect on your body’s sugar level. Honey is one of the best food to eat late at night.

12. Popcorn

When it isn’t swathed in sugar and milk and other fatty stuff, popcorn presents as a great late-night snack. Popcorn is a low-calorie snack and contains a rich amount of fiber.[9] High-fiber grains are believed to lower the risk of heart disease, diabetes, and some cancers.

Also, popcorn contains polyphenols. Polyphenols are antioxidants believed to improve circulation and in general, health.

13. Baked Sweet Potato Fries

French fries are amazing. They taste so good. Do you like french fries? Then baked sweet potato fries are a great pick you might want to consider.

As a late-night snack, you can very well bake sweet potatoes instead of frying them. They are easier to prepare when baked and do not contain so much fat. Sweet potatoes contain a good quantity of fiber and vitamins.[10]They also contain some great amounts of protein.

Final Thoughts

When next you have the craving for a late-night meal, you should know that not all meals are great when eaten at night. Some are about right, and others could contribute to excessive weight gain, heart diseases, digestive disorders, and other health issues.

Have you ever woken up with swollen eye bags, felt nauseous, or had malaise after a late-night meal? Then it’s possible the meal was not a great pick.

When choosing the best meals and snacks to eat at night, you should choose meals that contain low calories—not more than 200 calories—and have high protein content. Proteins like tryptophan enhance the quality of sleep. Some of these foods include eggs, turkey, cheese, bananas, yogurt, juices, etc.
