7 Scientifically-proven health benefits of eating nutrient-rich Brazil nuts

10/27/2019 / By Darnel Fernandez

Brazil nuts not only make a healthy and nutritious snack, they also offer a variety of health benefits. Research suggests that eating these nutrient-dense nuts can help reduce inflammation, improve heart health, and support thyroid function.

Sensational nuts

Brazil nuts, scientifically known as Bertholletia excelsa, are derived from trees with the same name. These trees are native to South America, particularly in the countries of Peru, Bolivia, and Brazil.

Brazil nuts are said to have a smooth and buttery texture and a nutty flavor. They can be eaten raw or blanched.

Here are seven reasons to add these nutritious nuts to your diet:

They are packed with nutrients

Brazil nuts are one of the healthiest nuts on the market. Data from the U.S. Department of Agriculture show that these nuts are a rich source of energy, healthy fats, and protein. An ounce (28.35 grams, g) of Brazil nuts contains the following nutrients:

Calories – 187 kcal
Protein – 4.06 g
Carbohydrates – 3.33 g
Fiber – 2.13 g
Healthy fats – 19 g

According to a study published in the journal Nutrients, Brazil nuts are packed with high levels of monounsaturated fatty acids (MUFA), which can aid in weight management, reduce inflammation, and prevent heart disease.

They are rich in selenium

Brazil nuts are considered one of the best sources of selenium, a mineral that plays a key role in reproductive health, immune response, and metabolism. Each nut contains an average of 96 micrograms (mcg) of selenium, which exceeds the recommended dietary intake of 55 mcg. Studies have also found that higher selenium intake can lead to improved mood, reduced cancer risk, and enhanced immunity.

They support thyroid function

The thyroid is responsible for secreting hormones that help with growth, temperature regulation, and metabolism. Because selenium is important for the production of hormones like triiodothyronine (T3) and proteins that protect the thyroid gland from damage, the highest concentration of this mineral can be found in the thyroid.

Low selenium intake has been linked to reduced thyroid activity and a higher risk of thyroid disorders, such as hypothyroidism. This suggests that meeting the daily requirement for selenium intake is important for the maintenance of proper thyroid function.

They help address thyroid disorders

Adequate selenium intake can also improve the symptoms of thyroid disorders. Studies have shown that selenium supplementation can enhance both mood and immune function in people with Hashimoto’s thyroiditis.

People with another thyroid disorder called Graves’ disease can also benefit from eating selenium-rich Brazil nuts. A study published in the journal Evidence-Based Complementary and Alternative Medicine showed that high selenium intake can improve thyroid function in people with this autoimmune disease.

They reduce inflammation

Brazil nuts are a rich source of antioxidants. Antioxidants help keep cells healthy by neutralizing free radicals, which are unstable molecules that can damage healthy cells. According to Brazilian researchers, a 20 to 50 g serving of Brazil nuts can significantly decrease the levels of inflammatory markers in the blood.

They improve heart health

A study published in The American Journal of Clinical Nutrition showed that consuming nuts can help lower bad cholesterol by at least 25 percent. Brazil nuts, in particular, contain heart-healthy fats like MUFAs and polyunsaturated fatty acids (PUFAs) that can help lower the risk of heart disease.

They improve brain health

Brazil nuts contain a polyphenol called ellagic acid, which has protective effects on the brain. The antioxidants in Brazil nuts also help improve cognitive function, especially in older adults.

Brazil nuts are nutritional powerhouses that provide substantial health benefits. These make them a good superfood to add to any diet. However, to avoid excessive selenium intake, it is advisable to eat Brazil nuts in moderation.
