Almonds are a favorite among nut-eaters. Try them sprinkled in salads or churned into butter. One ounce of almonds packs 6 grams of protein and almost half of your daily vitamin E needs. Like most nuts, they contain monounsaturated fats, which have been known to lower cholesterol and your risk of heart disease. Just be sure to stay away from the roasted stuff -- they're usually deep-fried in unhealthy fats.

Keep on cracking! These popular nuts -- grown in the heart of California -- are a must-have. Not only are they an excellent source of body-essential copper and manganese, but they make the AICR's (American Institute for Cancer Research) list of foods that fight cancer.

Avoid canned cashews that contain unhealthy fat and salt.

According to the International Tree Nut Council, 1 ounce of the smooth ivory seeds contains 4 grams of protein and more zinc than any other tree nut, which helps immune system functioning and enhances your senses of taste and smell.
