The Silent Danger of Brazil Nuts
In a reported case, a sixty-one-year-old woman developed vomiting, diarrhea, and severe abdominal pain after eating half to one Brazil nut per day for weight loss. Her case, published in a medical journal, highlighted a condition called selenosis, which is selenium poisoning.

Brazil nuts are an excellent source of selenium, a mineral important for health. But they are also incredibly concentrated. A single nut can contain more than the daily recommended amount. Eating just a few nuts daily over time can lead to a buildup that becomes toxic, causing symptoms that are sometimes mistaken for other serious conditions.
