Nuts are nature’s way of showing us that good things come in small packages. These bite-size nutritional powerhouses are packed with heart-healthy fats, protein, vitamins, and minerals. Of course, you can get too much of these good things: Nuts are high in fat and calories, so while a handful can hold you over until dinner, a few more handfuls can ruin your appetite altogether. And although nuts are a healthy choice by themselves, they’ll quickly become detrimental to any diet when paired with sugary or salty toppings or mixes. Here’s a look at the benefits of different types of nuts, as well as the best packaged products on supermarket shelves today.

 

Healhtiest nuts for weight loss

Almonds, Cashews, Pistachios

All nuts are about equal in terms of calories per ounce, and in moderation, are all healthy additions to any diet.Their mix of omega-3 fatty acids, protein, and fiber will help you feel full and suppress your appetite.The lowest-calorie nuts at 160 per ounce are almonds (23 nuts; 6 grams protein, 14 grams fat), cashews (16 to 18 nuts; 5 grams protein, 13 grams fat), and pistachios (49 nuts, 6 grams protein, 13 grams fat). Avoid nuts packaged or roasted in oil, instead, eat them raw or dry roasted, says Caplan. Roasted nuts may have been heated in hydrogenated or omega-6 unhealthy fats, she adds, or to high temperatures that can destroy their nutrients.

Walnuts

While all nuts contain heart-healthy monounsaturated fats, walnuts (14 halves contain 185 calories, 18 grams fat, 4 grams protein) have high amounts of heart-healthy alpha linoleic acid (ALA), a type of omega-3 fatty acid found in plants. Research has suggested that ALA may help heart , and a 2006 Spanish study suggested that walnuts were as effective as olive oil at reducing inflammation and oxidation in the arteries after eating a fatty meal. The authors of this study, funded in part by the California Walnut Commission, recommended eating around eight walnuts a day to achieve similar benefits.

Healthiest nuts for your brain

Peanuts

Technically legumes but generally referred to as nuts, peanuts are high in folate—a mineral essential for brain development that may protect against cognitive decline. (It also makes peanuts a great choice for vegetarians, who can come up short on folate, and pregnant women, who need folate to protect their unborn babies from birth defects, says Caplan.) Like most other nuts, peanuts are also full of brain-boosting healthy fats and vitamin E, as well. One ounce of peanuts (about 28 unshelled nuts) contains about 170 calories, 7 grams protein, and 14 grams fat.

Healthiest nuts for men

Brazil Nuts, Pecans

Creamy Brazil nuts are packed with selenium, a mineral that may protect against prostate cancer and other diseases. Just one nut contains more than a day’s worth, so eat these sparingly: Recent research has hinted that too much selenium may be linked to type 2 diabetes risk. One ounce of Brazil nuts (6nuts) contains about 190 calories, 19 grams fat, and 4 grams protein. Pecans are also good for men’s health: They’re loaded with beta-sitosterol, a plant steroid that may help relieve symptoms of benign prostatic hyperplasia (BPH), or enlarged prostate. One ounce of pecans (18 to 20 halves) contains about 200 calories, 21 grams fat, and 3 grams protein.

Almonds

Relatively low in calories, almonds have more calcium than any other nut, making them a great food for overall health. Plus, they are rich in fiber and vitamin E, an antioxidant that helps fight dangerous inflammation and possibly health conditions such as lung cancer and age-related cognitive decline. Because they’re so versatile, almonds are often a favorite among nut eaters: You can buy them raw, toasted, slivered, or coated with a variety of fun flavors.
