Superfoods for Diabetes
Not all healthy foods are created equal. Greens may be good for you, but the nutrients in iceberg lettuce may not be as plentiful as those in kale, spinach, and Swiss chard.
Besides nutrient content, the glycemic index (GI) of a food may also help you make healthy choices.
The GI measures how quickly a food will raise blood sugar. Low GI foods have a score of 55 or less, while high GI foods have a score of 70 or more.
In general, lower GI foods are a better choice for people with diabetes. Foods that are both nutritious and have a low GI are helpful in managing health and blood glucose levels.
Here are 10 superfoods that are especially good for those with diabetes.
1. Non-starchy vegetables
Non-starchy vegetables have fewer carbs per serving. They include everything from artichokes and asparagus to broccoli and beets.
This category of veggies goes a long way in satisfying your hunger and boosting your intake of vitamins, minerals, fiber, and phytochemicals.
These vegetables are also low in calories and carbohydrates, making them some of the few foods that people with diabetes can enjoy almost with abandon.
People given a low-calorie diet consisting of non-starchy vegetables might successfully reverse type 2 diabetes.
2. Unsweetened Greek yogurt
There is a 14 percent lower risk of type 2 diabetes with daily yogurt consumption.
With a low GI score, unsweetened Greek yogurt is full of healthy probiotics, calcium, and protein. It’s also a better option that regular yogurt due to its higher protein and lower carbohydrate content.
Always check nutrition labels, as some brands have a higher carbohydrate content than others, due to additions such as syrup flavorings, sweeteners, toppers, or fruit preserves.
Top unsweetened Greek yogurt with nuts and low GI fruits such as blackberries, blueberries, or raspberries.
3. Tomatoes
Whether eaten raw or cooked, tomatoes are full of lycopene. This a powerful substance that may reduce the risk of cancer (especially prostate cancer), heart disease, and macular degeneration.
Like other non-starchy fruits, tomatoes have a low GI ranking.
It's found 200 grams of raw tomato (or about 1.5 medium tomatoes) each day reduced blood pressure in people with type 2 diabetes. Tomato consumption might help reduce cardiovascular risk that’s associated with type 2 diabetes.
4. Blueberries and other berries
From vision-protecting vitamin C to filling fiber, blueberries are antioxidant powerhouses.
These berries have some of the highest antioxidant levels of any fruit or vegetable and may reduce the risk of heart disease and cancer. They also have anti-inflammatory properties.
Strawberries, raspberries, and blackberries are also excellent choices for people with diabetes.
5. Oranges and other citrus
The pulpiness of oranges and grapefruit provide a great source of fiber. To maximize this, make sure to eat the whole fruit rather than drink just the juice.
Eating citrus fruits could lower the risk of diabetes in women, but drinking the fruit juice could increase that risk.
The average orange has a GI score of 40 while unsweetened orange juice has a GI score of 50.
The citrus with the lowest GI score is grapefruit. With a score of 25, grapefruit has one of the lowest GI scores of all fruits.
6. Wild salmon and other fish with omega-3 fatty acids
Wild salmon is loaded with omega-3 fatty acids, which may lower your risk of heart disease.
It’s also full of vitamin D and selenium for healthy hair, skin, nails, and bones. Other nutrient-dense fish include herring, sardines, and mackerel.
Since fish and other protein foods don’t contain carbs, they won’t increase blood sugar levels. Adding salmon to a meal can help slow digestion of other foods eaten at that meal and help increase fullness.
Fish oil is another source of omega-3 fatty acids. Ask your doctor before taking any supplements to see which, if any, are best for your condition.
7. Walnuts, flax seeds, and other nuts and seeds
Walnuts and flax seeds contain magnesium, fiber, and omega-3 fatty acids.
Walnuts also contain alpha-linolenic acid, an essential fatty acid that boosts heart health and lowers cholesterol. They’re full of vitamin E, folic acid, zinc, and protein.
Many other nuts provide healthy fats and can curb hunger, but these two are particularly powerful.
Substituting nuts and other healthy fats for carbs can help lower blood sugar. Nuts generally have very low GI scores.
Want another reason to snack on nuts? Older research has shown the people who eat nuts regularly have less risk of developing diabetes.
8. Beans
Beans are among nature’s most nutritious foods.
They’re high in fiber and protein, making them a great option for vegetarians and vegans. They also deliver essential minerals like magnesium and potassium.
They’re low on the GI, too. Soya beans rank in around 16, while kidney beans come in at 24, and chickpeas around 28.
Beans may be a good way to control glycemic levels in people with type 2 diabetes. They can also reduce the risk of coronary heart disease.
9. Kale and other leafy green vegetables
Kale is the king of super healthy greens. It provides more than 100 percent of the recommended daily intake of vitamin A and K.
Collard greens are another leafy green that packs a ton of nutrients into a small package.
Kale contains chemicals called glucosinolates that help neutralize cancer-causing substances. It’s also full of potassium and has been shown to help manage blood pressure.
This is another reason it’s considered a superfood for those with diabetes.
10. Barley, lentils, and other whole grains
Whole grains are full of antioxidants and soluble and insoluble fiber. These help to metabolize fats and keep the digestive track healthy.
People who regularly eat hulled barley typically have lower blood cholesterol. The grain also keeps blood sugar levels stable.
Lentils are another good option since they provide B vitamins, iron, complex carbohydrates, and protein.
While 100 percent stone-ground whole wheat bread is considered a low GI food, other types of whole wheat bread may have medium GI rankings, with scores between 56 and 69.
Eating whole grains may help decrease the risk of developing type 2 diabetes, if you choose the right type.
