The most important health benefits of selenium-rich Brazil nuts include their ability to reduce inflammation, improve heart health, aid in skin care, boost weight loss, reduce the signs of aging, regulate thyroid function, and fight anxiety. These nuts also strengthen the immune system, stimulate growth and repair, improve the digestive process, lower the risk of cancer, and boost male fertility.
What are Brazil Nuts?
(scientifically known as Bertholletia excelsa), are a nutrient-dense and delicious type of nuts that come from a tree in South America bearing the same name. The tree is native to South American countries, including Venezuela, Colombia, Peru, and Brazil, and can often be found along the banks of major rivers. It’s quite a large tree, so the harvest of Brazil nuts is huge. These nuts are majorly exported from the South American continent and can now be found throughout the world.
According to a study by a group of researchers including Dr. Claudia Baider, Departamento de Ecologia, Universidade de São Paulo, Brazil, there is a concern that Brazil nut production has dropped significantly in recent years. Thus, it is now illegal to cut down a Brazil nut tree in Brazil. These trees almost exclusively produce fruit in undisturbed forests and the plants are somewhat fragile, so with Brazil nuts’ production decreasing, prices may rise in the coming years.

Selenium is a trace mineral which is extremely vital for the body as it has strong antioxidant power, fights free radicals and soothes inflammation, thus boosting overall health. Studies show that almost 1 billion people worldwide suffer from selenium deficiency, which makes Brazil nuts an important dietary choice. Selenium also helps reduce toxic mercury levels and thus, the incidence of cancer in the body.

Brazil nuts have a surprisingly high content of healthy unsaturated fats, commonly known as HDL or good forms of cholesterol or omega-3 fatty acids. This includes oleic acid and palmitoleic acid. These varieties of unsaturated fats, magnesium, vitamin E, and selenium content in Brazil nuts are, thus, connected with balancing the cholesterol profile of the body and improving heart health.

The abundant antioxidants in Brazil nuts help in preventing many chronic illnesses, including cancer and coronary heart disease. This is confirmed in a study conducted at the Department of Surgical Oncology, Roswell Park Cancer Institute, Buffalo, New York. The glutathione enabled by the presence of selenium is an enzymatic antioxidant that eliminates free radicals in all parts of the body that cause cancer.
Low levels of selenium are linked to anxiety, stress, and tiredness, according to recent research cited in the Biological Psychiatry journal. Also, nut consumption increases the metabolism of serotonin, a feel-good brain chemical, which controls mood, appetite, and sleep. Thus, regular intake of Brazil nuts rich in selenium can help relieve the various issues caused by selenium deficiency such as depression, mood issues, fatigue, and stress.

The selenium content, in Brazil nuts, plays a major role in the proper functioning of your thyroid gland. The thyroid gland is where some of the essential hormones in the body are produced, distributed, and regulated from.
The comprehensive profile of vitamins and nutrients in Brazil nuts makes it particularly good for improving skin health. The selenium, omega 3-fatty acids, and vitamins C and E in Brazil nuts give the skin a healthy glow and improve the elasticity of the skin, thereby preventing premature aging. Selenium stimulates the activity of glutathione, a powerful antioxidant compound that can remove free radicals from the skin cells that cause wrinkles and even skin cancer.
