Figuring out the best foods to eat when you have diabetes doesn’t have to be tough.
To keep things simple, your main goal should be managing your blood sugar levels.
It’s also important to eat foods that help prevent diabetes complications like heart disease.
Your diet can have a major role in preventing and managing diabetes.
Here are the 16 best foods for people living with diabetes, both type 1 and type 2.
Best foods for people living with diabetes
1. Fatty fish
Salmon, sardines, herring, anchovies, and mackerel are great sources of the omega-3 fatty acids DHA and EPA, which have major benefits for heart health (1Trusted Source).
Getting enough of these fats on a regular basis is especially important for people with diabetes, who have an increased risk of heart disease and stroke.
DHA and EPA protect the cells that line your blood vessels, reduce markers of inflammation, and may help improve the way your arteries function.
Research indicates that people who eat fatty fish regularly have a lower risk of acute coronary syndromes, like heart attacks, and are less likely to die from heart disease.
Studies show that eating fatty fish may also help regulate blood sugar.
A study involving 68 adults who had overweight or obesity found that participants who consumed fatty fish had significant improvements in post-meal blood sugar levels than participants who consumed lean fish.
Fish is also a great source of high quality protein, which helps you feel full and helps stabilize blood sugar levels.
2. Leafy greens
Leafy green vegetables are extremely nutritious and low in calories.
They’re also very low in digestible carbs, or carbs absorbed by the body, so they won’t significantly affect blood sugar levels.
Spinach, kale, and other leafy greens are good sources of many vitamins and minerals, including vitamin C.
Some evidence suggests that people with diabetes have lower vitamin C levels than people without diabetes, and they may have greater vitamin C requirements.
Vitamin C acts as a potent antioxidant and also has anti-inflammatory qualities.
Increasing dietary intake of vitamin C-rich foods can help people with diabetes increase their serum vitamin C levels while reducing inflammation and cellular damage.
3. Avocados
Avocados have less than 1 gram of sugar, few carbohydrates, a high fiber content, and healthy fats, so you don’t have to worry about them raising your blood sugar levels.
Avocado consumption is also associated with improved overall diet quality and significantly lower body weight and body mass index (BMI).
This makes avocados an ideal snack for people with diabetes, especially since obesity increases the chances of developing diabetes.
Avocados may have properties specific to preventing diabetes.
A 2019 study in mice found that avocatin B (AvoB), a fat molecule found only in avocados, inhibits incomplete oxidation in skeletal muscle and the pancreas, which reduces insulin resistance.
More research is needed in humans to establish the connection between avocados and diabetes prevention.
4. Eggs
Regular egg consumption may reduce your heart disease risk in several ways.
Eggs may decrease inflammation, improve insulin sensitivity, increase your HDL (good) cholesterol levels, and modify the size and shape of your LDL (bad) cholesterol.
A 2019 study found that eating a high fat, low carb breakfast of eggs could help people with diabetes manage blood sugar levels throughout the day.
Older research has linked egg consumption with heart disease in people with diabetes.
But a more recent review of controlled studies found that eating 6 to 12 eggs per week as part of a nutritious diet did not increase heart disease risk factors in people with diabetes.
What’s more, some research suggests that eating eggs may reduce the risk of stroke.
5. Chia seeds
Chia seeds are a wonderful food for people with diabetes.
They’re extremely high in fiber, yet low in digestible carbs.
In fact, 11 of the 12 grams of carbs in a 28-gram (1-ounce) serving of chia seeds are fiber, which doesn’t raise blood sugar.
The viscous fiber in chia seeds can actually lower your blood sugar levels by slowing down the rate at which food moves through your gut and is absorbed.
Chia seeds may help you achieve a moderate weight because fiber reduces hunger and makes you feel full. Chia seeds may also help maintain glycemic management in people with diabetes.
A study involving 77 adults with overweight or obesity and a diagnosis of type 2 diabetes found that eating chia seeds supports weight loss and helps maintain good glycemic control.
Additionally, chia seeds have been shown to help reduce blood pressure and inflammatory markers.
6. Beans
Beans are affordable, nutritious, and super healthy.
Beans are a type of legume rich in B vitamins, beneficial minerals (calcium, potassium, and magnesium), and fiber.
They also have a very low glycemic index, which is important for managing diabetes.
Beans may also help prevent diabetes.
In a study involving more than 3,000 participants at high risk of cardiovascular disease, those who had a higher consumption of legumes had a reduced chance of developing type 2 diabetes.
7. Greek yogurt
A long-term study involving health data from more than 100,000 participants found that a daily serving of yogurt was linked to an 18 percent lower risk of developing type 2 diabetes.
It may also help you lose weight, if that’s a personal goal.
Studies show yogurt and other dairy foods may lead to weight loss and improved body composition in people with type 2 diabetes.
The high levels of calcium, protein, and a special type of fat called conjugated linoleic acid (CLA) found in yogurt may help keep you full for longer.
What’s more, Greek yogurt contains only 6–8 grams of carbs per serving, which is lower than conventional yogurt.
It’s also higher in protein, which may promote weight loss by reducing appetite and thus decreasing calorie intake.
8. Nuts
Nuts are delicious and nutritious.
Most types of nuts contain fiber and are low in net carbs, although some have more than others.
Research on a variety of different nuts has shown that regular consumption may reduce inflammation and lower blood sugar, HbA1c (a marker for long-term blood sugar management), and LDL (bad) cholesterol levels.
Nuts may also help people with diabetes improve their heart health.
A 2019 study involving more than 16,000 participants with type 2 diabetes found that eating tree nuts — such as walnuts, almonds, hazelnuts, and pistachios — lowered their risk of heart disease and death.
Research also indicates that nuts can improve blood glucose levels.
A study with people with type 2 diabetes found that eating walnut oil daily improved blood glucose levels.
This finding is important because people with type 2 diabetes often have elevated levels of insulin, which are linked to obesity.
9. Broccoli
Broccoli is one of the most nutritious vegetables around.
A half cup of cooked broccoli contains only 27 calories and 3 grams of digestible carbs, along with important nutrients like vitamin C and magnesium
Broccoli may also help manage your blood sugar levels.
One study found that consuming broccoli sprouts led to a reduction in blood glucose in people with diabetes.
This reduction in blood glucose levels is likely due to sulforaphane, a chemical in cruciferous vegetables like broccoli and sprouts.
10. Extra-virgin olive oil
Extra-virgin olive oil contains oleic acid, a type of monounsaturated fat that may improve glycemic management, reduce fasting and post-meal triglyceride levels, and has antioxidant properties.
This is important because people with diabetes tend to have trouble managing blood sugar levels and have high triglyceride levels.
Oleic acid may also stimulate the fullness hormone GLP-1.
In a large analysis of 32 studies looking at different types of fat, olive oil was the only one shown to reduce heart disease risk.
Olive oil also contains antioxidants called polyphenols.
Polyphenols reduce inflammation, protect the cells lining your blood vessels, keep oxidation from damaging your LDL (bad) cholesterol, and decrease blood pressure.
Extra-virgin olive oil is unrefined, so it retains antioxidants and other properties that make it so healthy.
Be sure to choose extra-virgin olive oil from a reputable source, since many olive oils are mixed with cheaper oils like corn and soy.
11. Flaxseeds
Also known as common flax or linseeds, flaxseeds have a high content of heart-healthy omega-3 fats, fiber, and other unique plant compounds.
A portion of their insoluble fiber is made up of lignans, which may help decrease heart disease risk and improve blood sugar management.
A review analyzing 25 randomized clinical trials found a significant association between whole flaxseed supplementation and a reduction in blood glucose.
Flaxseeds may also help lower blood pressure.
A 2016 study involving participants with prediabetes found that a daily intake of flaxseed powder lowered blood pressure — but it did not improve glycemic management or insulin resistance.
More research is needed to investigate how flaxseed can help prevent or manage diabetes.
But overall, flaxseed is beneficial for your heart and gut health.
Plus, flaxseeds are very high in viscous fiber, which improves gut health, insulin sensitivity, and feelings of fullness.
