What foods will not raise your blood sugar

When you first found out you had diabetes, you tested your blood sugar often. Doing so helped you understand how food, activity, stress, and illness could affect your blood sugar levels. By now, you’ve got it figured out for the most part. But then—bam! Something makes your blood sugar zoom up. You try to adjust it with food or activity or insulin, and it dips really low. You’re on a roller coaster no one with diabetes wants to ride.

Do you know all these blood sugar triggers?

Knowledge is power! Look out for these surprising triggers that can send your blood sugar soaring:

1. Sunburn—the pain causes stress, and stress increases blood sugar levels.
2. Artificial sweeteners—more research is needed, but some studies show they can raise blood sugar.
3. Coffee—even without sweetener. Some people’s blood sugar is extra-sensitive to caffeine.
4. Losing sleep—even just one night of too little sleep can make your body use insulin less well.
5. Skipping breakfast—going without that morning meal can increase blood sugar after both lunch and dinner.
6. Time of day—blood sugar can be harder to control the later it gets.
7. Dawn phenomenon—people have a surge in hormones early in the morning whether they have diabetes or not. For people with diabetes, blood sugar can spike.
8. Dehydration—less water in your body means your blood sugar is more concentrated.
9. Nose spray—some have chemicals that trigger your liver to make more blood sugar.
10. Gum disease—it’s both a complication of diabetes and a blood sugar spiker.

Watch out for other triggers that can make your blood sugar fall. For example, extreme heat can cause blood vessels to dilate (widen). That makes insulin absorb more quickly and could lead to low blood sugar. If an activity or food is new, check your blood sugar before and after to see how you respond.

Diabetes is a disease in which blood sugar levels are not controlled well because the body either doesn’t have enough insulin or does not use the insulin it does have as well as it should. This causes excess sugar in the bloodstream, which can lead to health problems over time. There are three main types of diabetes: type 1, type 2, and gestational diabetes.

Part of diabetes management is keeping your blood sugar levels in the right range. This means that food choices—specifically those with high simple carbohydrate content—play a major role because the types of foods you eat have different effects on blood sugar. 

This article talks about the importance of food choices in diabetes management. It also provides a list of 10 foods that won’t spike blood sugar and adds how you can incorporate them into your diet.

Importance of Diet in Diabetes

Much of the food you eat is broken down into sugar (glucose), which gets released into the bloodstream. When blood sugar increases, the pancreas, an organ responsible for digestion and blood sugar regulation, releases the hormone insulin. Insulin then helps cells absorb the sugar to be used for energy or stored.

In diabetes, the body does not produce enough insulin to enable the cells to absorb enough sugar from the blood. Or the body might have enough insulin, but the cells do not respond to it. In both cases, this leads to there being too much sugar in the blood, which, over time can lead to serious health issues, such as vision loss, heart disease, and kidney disease.

Reducing sugar and other simple carbohydrates in your diet plays an important role in keeping blood sugar levels down, which can slow the progression of the disease and stave off such complications.

Types of Carbs

Carbohydrates are simply chains of sugar. Anytime you eat foods that contain carbohydrates, blood sugar increases. However, not all carbohydrates affect blood sugar the same. The two main types of carbs are:

• Simple carbohydrates: These are broken down quickly and thus provide quick energy to the body.
• Complex carbohydrates: Just like they sound, these are made up of long, complex chains of sugar, which makes them harder to break down. Because they take longer to break down, they do not cause rapid spikes in blood sugar.

For people with diabetes, choosing foods with complex carbohydrates rather than simple carbohydrates will make managing blood sugar levels easier.

Glycemic Index and Glycemic Load

When it comes to assessing foods based on how they increase your blood sugar, there is a tool for that called the glycemic index. The glycemic index assigns a number value to foods based on how quickly and how high they raise your blood sugar. Foods with a high glycemic index increase blood sugar quickly.

Glycemic load accounts for both the glycemic index and the quantity of carbohydrates in a serving. While it is generally best to eat low-glycemic foods to manage blood sugar, glycemic load might be a better indicator when making food choices. For example, while watermelon is considered a high-glycemic food, it is low on glycemic load.

Carb Counting

When it comes to carb counting, there is no one-size-fits-all approach. The amount of carbs you should eat each day depends on factors like your age, weight, and physical activity level. According to the Centers for Disease Control and Prevention (CDC), people with diabetes should aim to get about half of their calories from carbohydrates.

This requires a bit of math and considers the average number of calories you consume each day and that there are 4 calories per gram of carbohydrate. For example, if you need about 800 calories from carbs, then you would aim to eat about 200 grams of carbs each day.

One tip to bear in mind is that having approximately the same amount of carbs at each meal may help keep blood sugar levels steady throughout the day. Carb counting tools can make this all a bit easier.

10 Foods That Won’t Spike Your Blood Sugar Levels

When making food choices while managing blood sugar levels, it is important to select ones that won’t cause your blood sugar to increase quickly and significantly. Look for whether foods have complex or simple carbohydrates and opt for complex carbohydrates when possible.

Below are 10 foods that won’t spike your blood sugar levels and some ideas for incorporating them into your meals.

Dark Leafy Greens

You have likely heard that dark leafy greens are good for you. They are rich in vitamins A, C, and K as well as minerals like iron and calcium. They are also low in carbs and high in fiber, which aids blood sugar control. Try mixing kale into a bean and veggie-full salad or to soups. Spinach or arugula can add a fresh crunch to savory sandwiches (watercress makes an excellent topping to avocado toast).

Spices

Some spices have hypoglycemic effects—that is, they help lower blood sugar. Thus, adding some of these spices to foods may help control blood sugar at mealtimes. Some hypoglycemic spices include cinnamon, turmeric, and ginger. Try adding cinnamon to oatmeal topped with fruit and nuts or look for ginger turmeric tea.

Non-Starchy Vegetables

Like dark leafy greens, non-starchy vegetables are rich in fiber, low in carbs, and blood-sugar friendly. Because they aren’t starchy and have lots of fiber, they won’t cause a blood sugar spike. Some examples of non-starchy veggies are onions, mushrooms, zucchini, broccoli, celery, and brussels sprouts. Here’s a good sauteed veggie combination to mix into a pasta dish: onion, garlic, broccoli, and zucchini.

Low-Glycemic Fruits

Low-glycemic fruits are sweet without causing a blood sugar spike. Most fruits naturally have a low glycemic index because of the fructose and fiber they contain. Apples, pears, oranges, berries, and grapefruit are some examples. Try mixing these fruits into oatmeal for a hearty breakfast or into Greek yogurt for a satisfying snack.

Whole Grains

Whole grains are low glycemic index foods. Unlike processed, refined grains (like white flour), whole grains are unrefined and, therefore, contain the germ and bran part of the grain. These parts provider fiber, which helps slow the release of sugar into the bloodstream.

Some common whole-grain foods are brown rice, quinoa, amaranth, oats, and whole-grain bread. Oats are whole grains that have been shown to improve glycemic control and insulin sensitivity, which, in turn, help keep blood sugar levels low. Overnight oats make an easy and quick breakfast. For anything you’d pair with toast, try using whole grain bread.

Healthy Fats

Fat helps slow digestion, which delays the absorption of carbohydrates into the blood. Adding healthy fats to your meals not only helps you stay fuller longer but also keeps blood sugar from spiking.

Some examples of healthy fats include:

• Olive oil
• Avocado
• Seeds (chia, flax, sunflower, pumpkin)

Try making your own salad dressings with olive oil at the base or making avocado your bread spread instead of butter.

Protein Sources

Protein, like fat, helps slow digestion, which delays the absorption of carbohydrates into the blood. And because protein takes longer to break down, it helps keep you fuller longer.

Examples of high-protein foods include:

• Quinoa
• Beans and rice
• Soy products
• Eggs
• Dairy

Try quinoa and bean burgers as a protein-rich dinner or a hardboiled egg with paprika for a snack.

Non-Sugar-Sweetened Beverages

While it is becoming increasingly known that sugar-sweetened beverages are unhealthy, they are particularly unhealthful for people trying to manage blood sugar. Unlike the naturally occurring sugars in fruit, the sugar in sugar-sweetened beverages is refined sugar, which causes immediate blood sugar spikes.

Instead, focus on drinking plenty of water. For fun flavors without the sugar, try adding fruit to water to make a naturally sweetened, refreshing beverage. Carbonated waters with no added sugar are also a better option for satisfying that craving for a carbonated beverage without the excess sugar.

Beans, Peas, and Lentils

Legumes are nutrient dense and have a low glycemic index, making them a great addition to diabetic-conscious meals. Some common legumes are lentils, beans, peas, and chickpeas. Legumes are also high in fiber, which helps keep blood sugar from spiking since the fiber slows the breakdown of the foods. Try making a hearty lentil soup or having a chickpea hummus to dip veggies into.

Nuts

Nuts are full of unsaturated fats (monounsaturated and polyunsaturated fats), which are generally considered healthy fats. Research has shown that unsaturated fatty acids may play a part in blood sugar control through reduced insulin resistance.

Nuts high in unsaturated fats include walnuts, almonds, pistachios, pecans, and peanuts. Try peanut butter on celery for a fresh and satisfying snack or add walnuts or pecans to your oatmeal or granola mix.

Summary

The foods you eat directly impact blood sugar, which means that food choices play an important role in blood sugar regulation. Choosing low-glycemic foods, such as those with whole grains and fiber, helps keep blood sugar under control.

A Word From Verywell

For people with diabetes, being aware of how food will impact blood sugar is an everyday feat. Yet, it is worth it. Managing blood sugar has both short-term and long-term benefits, including lowering the risk of diabetes-related complications.

While the importance of making food choices that will keep blood sugar levels in check can’t be understated, it is also important to note that finding what works is an individual choice. We share these ideas on foods that won’t spike your blood sugar as a guide and inspiration when everyday food choices are made.

Food can be fun, even when thinking about how it’s going to affect your blood sugar. We hope this article helps you find new ideas that work for you.

Frequently Asked Questions

• What foods can you eat to lower your blood sugar instantly?

  You may see some sources that claim to instantly lower your blood sugar, but there isn’t enough research to support these claims. It is best to speak to your healthcare provider about how to bring down high blood sugar levels, which may include taking insulin or other blood-sugar regulating medication.

• What can you eat when your blood glucose is high?

  When your blood sugar is high, it is best to avoid foods that will add to the problem, like foods with simple carbohydrates, or refined sugars. Stick to foods with a low glycemic load, like non-starchy vegetables, whole grains, and foods with more healthy fat and protein. Foods with fiber can help slow the release of blood sugar and thus are helpful when blood sugar is high.

• Which drinks can regulate your blood sugar?

  Fruit- or spice-infused water or carbonated water with no sugar added will keep you hydrated without causing problems with your blood sugar. Tea is also a zero-sugar beverage that contains antioxidants, which have been shown to help regulate blood sugar levels.

• In what ways can you lower your blood sugar?

  In addition to making food choices that are blood-sugar-aware, exercise is one way to help lower your blood sugar. When you are physically active, your muscles burn sugar (glucose) for energy and use it for muscle building and repair. This helps pull sugar from the blood, lowering blood sugar levels. Resistance training, such as strength workouts, has been shown to improve blood sugar control.
