Brazil nuts are large and creamy nuts that are produced by the Bertholletia excelsa tree found in the Amazon rainforest region. Brazil nuts are mostly famous for having very high levels of selenium, a mineral that is required by the body in small quantities.
Some other nutrients that one will obtain from Brazil nuts include healthy fats, proteins, fibre, magnesium, copper, and zinc. Although nutritious, Brazil nuts are not like other nuts owing to their high levels of selenium. This makes it necessary to consume them in moderation.
Nutritional Content of Brazil Nuts
In a regular 28-gram serving of Brazil nuts, there are about 185-190 calories, 4 grams of protein, 19 grams of fat, and about 2 grams of fibre.
Most of the fat found in Brazil nuts is unsaturated. Other nutrients in Brazil nuts include magnesium, phosphorus, copper, zinc, and vitamin E. Selenium is the most notable nutrient in Brazil nuts, although it has varied levels.
- Excellent Source of Selenium
Brazil nuts are one of the most selenium-rich foods.
Selenium is necessary for many enzymes and proteins that are essential in antioxidant defence, thyroid hormone metabolism, and normal immune system function.
Since Brazil nuts contain so much selenium, having more does not always mean better. Just a few nuts will supply you with plenty.
- Promotes Healthy Thyroid
Thyroid glands require selenium in order to produce and metabolise thyroid hormones, which regulate metabolism, growth, and energy expenditure.
Therefore, eating Brazil nuts can provide dietary selenium and thus promote normal thyroid function, provided they are consumed in adequate amounts.
However, Brazil nuts should not be seen as a way to treat any thyroid problems like hypothyroidism, for example. If you have any thyroid issues, please follow your doctor’s recommendations.
- Serves as an Antioxidant
One of the components of many antioxidant enzymes is selenium. Antioxidant enzymes are crucial to protect your body from oxidative stress.
Brazil nuts are also rich in other naturally occurring antioxidants.
It has been shown in scientific studies that consumption of Brazil nuts can increase the level of selenium in the body and improve its antioxidant potential, especially when selenium intake is low.
- May Support Heart Health
The nuts are known sources of monounsaturated fats, polyunsaturated fats, magnesium, and other nutrients.
Replacing foods with saturated fat content with proper proportions of nuts with higher amounts of unsaturated fat can be one part of heart-focused dietary habits.
The research on Brazil nuts and cholesterol yielded conflicting results, which is why these nuts cannot be used as a treatment for high cholesterol and heart disease.
- Helps to Maintain Proper Functioning of Immune System
Selenium, zinc, and other nutrients contained in Brazil nuts help to maintain normal functioning of the immune system.
Selenium takes part in immune reactions and antioxidative defences. Nonetheless, the consumption of high amounts of selenium does not mean having an improved immune system and can result in selenium toxicity.
It is still necessary to have a varied diet and enough rest and exercise for maintenance of proper functioning of the immune system.
- Can Be Helpful for Nervous System
Brazil nuts include selenium, magnesium, and healthy fats, which help to maintain a normal nervous system.
Moreover, the researchers studied the connection between selenium deficiency and cognitive functioning. It seems like an interesting topic, but Brazil nuts should not be promoted as a prevention for memory loss and dementia.
Their benefit lies in the provision of valuable nutrients for the body.
- Provides Magnesium
The Brazil nut is a good source of magnesium, a mineral essential for many biochemical reactions in the human body.
It has a role in ensuring proper functioning of muscles and nerves, energy metabolism, and bone health.
Consuming Brazil nuts with vegetables, whole grains, pulses, seeds, and other nuts will help you get magnesium from various sources in your diet.
- Helps in Appetite Control
As mentioned earlier, the Brazil nut contains healthy fats, proteins, and fibre in small quantities. It may keep you satisfied.
You may want to consume it as a replacement for high-calorie snacks. However, the Brazil nut has a high caloric content. Therefore, controlling the portion size is crucial for effective weight management.
- Promotes Skin Health
The Brazil nut contains selenium, vitamin E, healthy fats, and other nutrients, which help maintain proper skin and cell functioning.
Its antioxidants play a part in protecting cells from oxidative stress, while the fats from the diet help in the maintenance of proper skin structure.
Nonetheless, the Brazil nut is certainly not a remedy for any skin condition like acne, wrinkles, or pigmentation.
- Convenient Nutrient-Dense Snack
The Brazil nut requires no preparation and contains several nutrients in one small portion.
You can eat it raw or chop it into your oatmeal, yoghurt, or salad. The unsalted Brazil nut is better, especially when consumed often by people who are trying to reduce their sodium intake.
How Many Brazil Nuts Should You Eat?
This is crucial to understand regarding Brazil nuts since their selenium content varies widely and each nut may have a significant amount of selenium.
Instead of consuming a handful of Brazil nuts as one does with almonds or cashews, Brazil nuts are recommended to be consumed in small amounts. Consuming too many Brazil nuts regularly will cause the consumption of excess selenium.
Those who take selenium supplements need to be especially cautious with their consumption of Brazil nuts.
Side Effects
Too much consumption of selenium will lead to nausea, diarrhoea, bad breath that smells like metal or garlic, brittle nails, and hair loss. Too much of it will cause severe side effects in people.
Consuming Brazil nuts will also cause an allergic reaction in people who are allergic to tree nuts.
People suffering from kidney diseases, tree-nut allergies, and those whose diet is medically restricted need to seek individual dietary advice before consuming Brazil nuts.
Personal Preference for Brazil Nuts
My personal interest in Brazil nuts is the nutritional density of this food despite its small size. In most other foods, when a handful is a portion, it shows that it needs to be consumed moderately.
In the case of Brazil nuts, I prefer to use them occasionally when I eat a mixture of various nuts in a handful.
Conclusion
Brazil nuts provide selenium, healthy fats, protein, magnesium, copper, and antioxidants. In moderate quantities, they will help in maintaining proper thyroid function, antioxidant protection, and the immune system.
