Choosing and Storing Brazil Nuts
For maximum quality and nutrition, pick Brazil nuts that are full, uniform, and without signs of mold or rancidity. Opt for unsalted and unroasted varieties to control added sodium and preserve healthy fats. Store nuts in an airtight container in the refrigerator or freezer to extend their shelf life and protect them from humidity and spoilage, as their high oil content makes them susceptible to going rancid.
Key Considerations and Potential Interactions
Brazil nuts are highly nutritious, but their selenium content requires mindful consumption. Eating just one or two nuts daily can meet or exceed the recommended daily selenium intake. Consuming large amounts regularly may cause selenium toxicity, with symptoms like gastrointestinal upset, hair loss, and brittle nails. They may also trigger nut allergies in sensitive individuals. Those with specific medical conditions or taking certain medications should consult a healthcare provider before increasing intake.
