Limit Your Brazil Nut Intake
Nuts contain heart-healthy protein and are a great source of energy, but eating too many Brazil nuts may cause problems. Brazil nuts contain selenium, and consuming too much of it can lead to selenium toxicity. If you get selenium toxicity, you might experience hair loss, decreased nail health, and can even digestive and memory problems.
It’s recommended that you don’t eat any more than 300 micrograms of Brazil nuts per day. The recommended daily amount is 50-70 micrograms.
