What Happens to Your Body When You Eat Peanuts — Surprising Benefits (and a Few Cautions)

The Humble Snack With Remarkable Nutrition

Peanuts are often overlooked in favor of almonds, walnuts, pistachios, and other trendy snack foods. Yet despite their modest reputation, peanuts are among the most nutrient-dense foods available.
