Calories in Walnuts
The omega-3 nut, and one of the most calorie-dense
654 kcal
What makes walnuts so powerful?
Walnuts are about 654 calories per 100 g, the highest of the common nuts, because they are around 65% fat. Unlike most nuts, much of that fat is alpha-linolenic acid, a plant omega-3. A 28 g serving (about 14 halves) is roughly 185 calories. Their ridged shape makes them look lighter than they are, so weigh rather than guess.

Weigh them
Halves are deceptively dense.
💡 When & how to use it
Add a few halves to oats or salads instead of snacking from the bag. Store in the fridge so the oils stay fresh.
