brazil nuts selenium - #28564
I am really confused about this whole thing with brazil nuts and selenium. A few weeks ago, I read that they're like superfoods or something, especially for selenium. I started eating them every day because I thought, why not? I mean, I’ve been feeling kind of sluggish lately. But then I heard that too much selenium isn’t good either, and now I’m worried. I eat 2 or 3 brazil nuts a day, because I've heard that can be enough to cover your daily selenium needs, but does that mean I'm at risk of getting too much selenium? And lately, I’ve noticed some weird symptoms like a metallic taste in my mouth and really dry skin. Could that be linked to the selenium from the brazil nuts, or is it something else? I just don’t know what to think anymore. I read that selenium is good for your immune system and thyroid, but now I'm like, are these nuts really worth it if I might be overdoing it? How much selenium is too much anyway? Should I stop eating brazil nuts or cut back? Any advice would really help me out here!

Doctors' responses
Let’s dive into the facts about selenium and Brazil nuts. Brazil nuts are indeed high in selenium, and just one or two can meet or even exceed the daily recommended intake for most adults, which is about 55 micrograms per day. In fact, a single Brazil nut can contain anywhere from 70 to 90 micrograms, depending on the nut itself. While selenium is important for your immune function and thyroid health, it is possible to consume too much. The upper limit for selenium is set at 400 micrograms per day. Going above this can lead to selenium toxicity, which might explain the symptoms you’re experiencing like metallic taste and dry skin. Other signs of excess selenium can include hair loss, nausea, irritability, and nervous system abnormalities. If you’re regularly consuming 2 to 3 Brazil nuts each day, you might be approaching or exceeding the upper intake level, especially if you’re also getting selenium from other dietary sources. In terms of addressing your current concerns, it would be wise to reduce your intake to one Brazil nut per day or even every other day, depending on your overall diet. It’s also a good idea to keep track of other sources of selenium in your meals, supplements, or fortified foods to avoid excess. Given your symptoms, though not necessarily severe, it would be prudent to discontinue the nuts for now and observe if the symptoms improve over a week or two. If symptoms persist or worsen, it would be sensible to consult a healthcare provider to explore other potential causes and ensure there’s no underlying condition that needs attention. It’s all about balance and making sure your intake aligns with recommended dietary guidelines. Keep everything in moderation to reap the benefits without veering into the realm of risk.
