FAQ
Are roasted peanuts as healthy as raw ones?
Roasting slightly reduces some heat-sensitive nutrients like B vitamins but does not significantly alter the protein, fat, or mineral content. The main difference is the added salt in many roasted varieties.
Why do peanuts sometimes cause digestive discomfort?
Peanuts contain fiber and phytic acid, which can cause gas or bloating in some people, especially if eaten in large quantities. Soaking or cooking peanuts (as in boiled peanuts) can reduce phytic acid and improve digestibility.
What's the best way to store roasted peanuts?
To maintain freshness and prevent the oils from going rancid, store them in an airtight container in a cool, dark place. For longer storage, the refrigerator or freezer is ideal.
