Brazil nuts are the number one source of selenium, with one ounce (about 6 kernels) serving 774% DV. 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 connected with balancing the cholesterol profile of the body and improving heart health.
The high ellagic acid and selenium levels in the nuts make it a top anti-inflammatory food source. Ellagic acid also has potent neuroprotective properties. Furthermore, zinc in Brazil nuts reduces inflammations and helps flush out toxins.
Brazil nuts, with their high selenium content, are often called a testosterone superfood. Dietary selenium can help to improve sperm quality, motility, and volume, according to a research study published in the Journal of Andrology. This, in turn, is linked with testosterone levels in men as higher the testosterone, higher the sperm count. L-arginine in the nuts is also an effective treatment for erectile dysfunction.
The abundant antioxidants in Brazil nuts help in preventing many chronic illnesses, including cancer and coronary heart disease. 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. 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. Also, Brazil nut oil is an excellent emollient which helps prevent skin dryness, eczema, and psoriasis. Additionally, grinding a handful of nuts and mixing it with an egg makes for a deeply nourishing skin exfoliator.
Copper in Brazil nuts aids in the production of melanin, a color pigment that protects the skin from harmful ultraviolet rays, and thereby prevents skin cancer.
