Snack staples may be behind the rise of cancer in the United States.
Brazil nuts, a common nut rich in antioxidants, contain beneficial minerals and nutrients. They are a good source of B vitamins, calcium, zinc, magnesium and vitamin E.
Nuts are high and very low in monosaturated fats, which help lower cholesterol and improve heart health and reduce the risk of stroke. They are also said to relieve inflammation in the body, strengthen bones and improve cognition.
It is believed that an essential mineral in Brazil nuts can boost the immune system and support thyroid function, but in fact too many can have the opposite effect and be harmful to your health.
People over 14 years of age are advised to receive 55 micrograms (MCG) of selenium per day. Recommendations for infants, children and adolescents range from 15 MCG and 40 MCG per day.
Selenium does have benefits, but it is easy to over-consuming this powerful mineral, while Brazil nuts contain high concentrations – about 544mcg per 1 ounce of portion, usually only six nuts.
Because of this high content, people warn to consume more than one or two nuts a day, because excessive selenium is associated with dyspnea, tremors, kidney failure and heart attacks.
Although previous studies have shown that selenium has cancer prevention properties, newer studies actually show that the opposite is true – it may increase the risk of disease.
Brazil nuts contain a high concentration of selenium – about 544 mm per 1 ounce of the plot, usually only six nuts.
The daily recommended value of minerals is also easy to get in tuna, sardines, shrimps, beef, pork, turkey, eggs and spaghetti – but these can be enjoyed without worrying about overdose of Selenium.
Dr. Steven Quay, a physician-scientist who specializes in cancer research, calls selenium a “double-edged sword.”
He told Dailymail.com: “On the one hand, this is an important trace mineral for your body to use for DNA synthesis, thyroid function and immunity. Another? Going past the 400 mcg/day line, you are flirting with selenium – garlic breathing, crisp nails and worse.
“Some studies praised it for its toxicity to neutralize Mercury, while others warned: “Guys, it’s not cancer.” “The truth? Dosage is important. Like all powerful tools, it is balanced-not abundant.
Although people only need a small amount of selenium, it does play an important role in the body. It is involved in DNA production and protection, and according to NIH, it has been shown to improve cognitive scores and improve sperm movement in older people.
“Selenium is a limited amount recommended by doctors does have benefits when it comes to limited amounts,” urologist Dr. Martina Ambardjieva told Dailymail.com.
But, people who consume too much – NIH says the maximum safety limit for people over 14 is 400 mcg – can cause selenium toxicity and cause various symptoms.
These include nausea, vomiting, diarrhea, hair loss, nails, rotten teeth, arthritis and inflammation, Dr. Ambardjieva said.
It is not yet known how many selenium toxic cases are recorded each year.
Despite the dangers, minerals have long been believed to play a role in preventing cancer due to the DNA-protecting properties of selenium.
But a comprehensive review of the matter found.
Cochrane 2018 Review Whether selenium intake or supplementation, known as selenium prevention, is reduced by selenium tests.
Analyzing data from 10 studies involving 27,000 people, the review found no evidence that selenium supplements reduce cancer incidence.
Additionally, the researchers said some of the studies included in their comments “has attracted people’s attention” as they reported the occurrence of prostate cancer and type 2 diabetes in people taking selenium supplements.
Not only does minerals not prevent cancer, but other studies have shown that it may actually increase the risk.
It is also easy to get the daily recommended value of selenium in the supplement, as well as tuna, sardines, shrimps, beef, pork, pork, turkey, eggs and pasta

2024 study Nature published in Nature found that people with the lowest and highest selenium intakes have a greater chance of cancer.
After analyzing nearly 3,000 people in the Vietnamese database, the researchers found that the “safe” intake levels of selenium were 111 mcg to 124 mcg.
Those who consume 28 to 77 MCG, while those who consume 169 MCG to 332 MCG are at an increased risk of cancer. Gastric, colon, rectum, and lung cancer are the highest.
For high endurance, the chance of developing cancer is 86%. The chances of low smart groups are three times higher.
Research Since 2002, the population with the highest levels of selenium in the blood – 122 or higher Ng/ml (nanograms per milliliter) – has increased cancer incidence by 20%. However, people in the two low-dose groups (less than 122 ng/mL) showed 30% to 49% of the cancer incidence.
Separate from the third one study The second most common type of skin cancer was found to be a “statistically significant” increase (25% increase) in selenium supplementation with squamous cell carcinoma.
Additionally, health officials warn that selenium may impair the effects of immunosuppressants, birth control and cholesterol drugs, while aggravating the effects of anticoagulants and sedatives.
Because of the wide range of results and sometimes contradictory conclusions, experts say more research is needed to examine the relationship between selenium and cancer.
Prior to this, it is recommended to take only doctor-assisted medications.
