Adding Nuts to Your Diet

Serving Size Tips
You can support good nutrition by choosing the right serving size of nuts each day. The recommended daily intake for optimal vitamin and mineral intake is 30 grams. This amount equals about 20 almonds or 10 walnuts. You get health benefits such as a reduced risk of heart disease when you follow this guideline. Most nuts contain healthy fats, protein, and fiber. You absorb fewer calories from nuts than you might expect because their fibrous structure prevents complete digestion.
