Foods to Lower Your Blood Sugar
Foods to Lower Your Blood Sugar
Blog Article
Several foods may help lower your blood sugar, but some may be more effective than others.
Although factors such as body weight, activity, stress, and genetics also play a role in regulating blood sugar, following a healthy diet is critical for blood sugar management.
While some foods, including those high in added sugar and refined carbs, can contribute to blood sugar fluctuations, others can optimize blood sugar regulation while promoting overall health.
Here are foods that may help regulate your blood sugar.
1. Broccoli and broccoli sprouts
Sulforaphane is a type of isothiocyanate that has blood sugar-reducing properties. This plant chemical is produced through an enzyme reaction when broccoli is chopped or chewed.
Test-tube, animal, and a few human studies have shown that sulforaphane-rich broccoli extract has potent antidiabetic effects, helping enhance insulin sensitivity and reduce blood sugar and oxidative stress markers.
Broccoli sprouts are concentrated sources of glucosinolates such as glucoraphanin. Research suggests that these compounds help promote insulin sensitivity and reduce blood sugar levels in people with type 2 diabetes when supplemented as a powder or extract.
Additionally, eating cruciferous vegetables may reduce the risk of type 2 diabetes, but more research is needed.
The best way to enhance the availability of sulforaphane is to enjoy broccoli and sprouts raw or lightly steamed or add active sources of myrosinase, such as mustard seed powder, to cooked broccoli.
2. Seafood
Seafood, including fish and shellfish, is a valuable source of protein, healthy fats, vitamins, minerals, and antioxidants that may help regulate blood sugar levels.
Protein is essential for blood sugar management. It helps slow digestion, prevents postmeal blood sugar spikes, and increases feelings of fullness. Plus, it may help prevent overeating and promote excess body fat loss, two essential effects for healthy blood sugar levels.
A high intake of fatty fish such as salmon and sardines has been shown to help improve blood sugar regulation.
For example, in a small study with 68 participants, adults with overweight or obesity who consumed 26 ounces (oz), or 750 grams (g), of fatty fish per week had significant improvements in postmeal blood sugar levels compared with those who consumed lean fish.
3. Pumpkin and pumpkin seeds
Brightly colored and packed with fiber and antioxidants, pumpkin is a great choice for blood sugar regulation. Pumpkin is a traditional diabetes remedy in many countries, including Mexico and Iran.
Pumpkin is high in carbs called polysaccharides, which have been studied for their blood sugar-regulating potential. Treatments with pumpkin extracts and powders have been shown to significantly decrease blood sugar levels in both limited human studies and animal studies.
However, more research is needed to determine how whole pumpkins may benefit blood sugar.
Pumpkin seeds are packed with healthy fats and protein, which make them an excellent choice for blood sugar management.
4. Nuts and nut butter
Research has shown that eating nuts may be an effective way to help regulate blood sugar levels.
In a small study of 25 people with type 2 diabetes, consuming both peanuts and almonds throughout the day as part of a low-carb diet reduced fasting and postmeal blood sugar levels.
Also, a review found that consuming various types of tree nuts led to reduced fasting blood sugar levels in people with type 2 diabetes. However, the authors noted that the results were not clinically significant and that more research is necessary.
5. Okra
Okra is a fruit that’s commonly used like a vegetable. It’s a rich source of blood sugar-lowering compounds such as polysaccharides and flavonoid antioxidants.
Okra seeds may be beneficial as a natural remedy for diabetes due to their potent blood sugar-lowering properties.
Rhamnogalacturonan, the main polysaccharide in okra, has been identified as a powerful antidiabetic compound. Plus, okra contains the flavonoids isoquercitrin and quercetin 3-O-gentiobioside, which help reduce blood sugar by inhibiting certain enzymes.
Although animal studies suggest that okra has potent antidiabetic properties, human research studies are needed.
6. Flaxseed
Flaxseed is rich in fiber and healthy fats and may help reduce blood sugar levels.
In an 8-week study of 57 people with type 2 diabetes, those who consumed 7 oz (200 g) of 2.5% fat yogurt containing 1 oz (30 g) of flaxseed each day experienced significant reductions in HbA1c—a marker of long-term blood sugar regulation—compared with those who consumed plain yogurt.
Moreover, a review of 25 controlled studies found that eating whole flaxseed led to significant improvements in blood sugar regulation.
7. Beans and lentils
Beans and lentils are rich in magnesium, fiber, and protein. These nutrients may be able to help lower blood sugar. They’re particularly high in soluble fiber and resistant starch, which help slow digestion and may improve blood sugar response after meals.
For example, a study of 12 women demonstrated that adding black beans or chickpeas to a rice meal significantly reduced postmeal blood sugar levels compared with eating rice alone.
Many other studies have shown that eating beans and lentils can benefit blood sugar regulation and possibly help protect against the development of diabetes.
8. Kimchi and sauerkraut
Fermented foods such as kimchi and sauerkraut contain health-promoting compounds, including probiotics, minerals, and antioxidants. Research associates these compounds with improved blood sugar and insulin sensitivity.
A 2021 review concluded that probiotic foods had a notable effect on blood sugar regulation in people with type 2 diabetes. Researchers noted that these foods had the greatest impact on people whose diabetes was not well managed and those who were not on insulin therapy.
However, most studies into the effect of fermented foods on blood sugar regulation involve rodent or cellular investigations. As a result, further controlled human studies are necessary.
9. Chia seeds
Eating chia seeds may benefit blood sugar regulation. Some studies link chia seed consumption to reductions in blood sugar levels and improvements in insulin sensitivity.
A 2020 review of 17 animal studies concluded that chia seeds might help improve insulin sensitivity and blood sugar regulation and potentially reduce disease risk, including the risk of diabetes.
Also, a study of 15 healthy adults showed that participants who received 1 oz (25 g) of ground chia seeds alongside 2 oz (50 g) of a sugar solution had a 39% reduction in blood sugar levels compared with those who consumed the sugar solution alone.
10. Kale
People often describe kale as a “superfood”—and ”for a good reason. It contains multiple compounds that may help decrease blood sugar levels, including fiber and flavonoid antioxidants.
A study that included 42 Japanese adults demonstrated that consuming either 7 or 14 g of kale-containing foods with a high-carb meal significantly decreased postmeal blood sugar levels compared with placebo.
Research has shown that the flavonoid antioxidants found in kale, including quercetin and kaempferol, have potent blood sugar-lowering and insulin-sensitizing effects.
11. Berries
Numerous studies link berry intake with improved blood sugar regulation. Berries contain fiber, vitamins, minerals, and antioxidants, and all of this makes them an excellent choice for people with blood sugar management issues.
A 2019 study found that eating 2 cups (250 g) of red raspberries with a high-carb meal significantly reduced postmeal insulin and blood sugar in adults with prediabetes compared with a control group.
In addition to raspberries, studies have shown that strawberries, blueberries, and blackberries may benefit blood sugar management by enhancing insulin sensitivity and improving glucose clearance from the blood.
The bottom line
Following a healthy dietary pattern is essential for optimal blood sugar management.
Whether you have prediabetes or diabetes or want to reduce your risk of developing these conditions, including the foods listed above as part of a nutritious diet may help lower your blood sugar levels.
However, keep in mind that your overall dietary intake, as well as factors such as your activity level and body weight, are most important when it comes to optimizing blood sugar regulation and protecting against chronic disease.
