They're particularly high in selenium, a mineral with potent antioxidant properties. Eating Brazil nuts may reduce inflammation, support brain function, and improve your thyroid function and heart health. To avoid consuming too much selenium, limit your intake to one to three Brazil nuts per day.

Reduced Risk of Heart Disease

Brazil nuts contain high levels of monounsaturated fats, which are healthy fats.  Incorporating monounsaturated fat into your diet can help to improve your cholesterol levels, which can reduce your risk of heart disease. The dietary fiber in Brazil nuts can also help to lower blood cholesterol levels, reducing the risk of heart disease and stroke.

Diabetes Management

Some studies show that the selenium in Brazil nuts can help to lower insulin levels and boost insulin sensitivity, improving blood sugar levels in people with type 2 diabetes.

Inflammation Relief

Brazil nuts have several antioxidants, including vitamin E and phenols. Antioxidants can help to fight free radicals, reducing oxidative stress and inflammation in your body. Lowering inflammation can help to reduce your risk of various health conditions, such as heart disease, diabetes, and certain types of cancer.

Bone Health

Brazil nuts have calcium and magnesium, both of which are necessary for bone health. A 1-ounce serving of Brazil nuts has about 25% to 33% of your recommended daily dose of magnesium, which plays an important role in bone density. More magnesium can lead to higher bone density.

Brain Health

Low levels of selenium are linked to neurodegenerative conditions such as Parkinson’s disease and Alzheimer’s disease. The antioxidants in Brazil nuts, including selenium, can help to boost your brain health. Some research also shows that increasing your selenium intake can help to improve your mood.
