Nr 218 Should you go nuts?

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.

Here's a look at the pros and cons of different nuts, as well as the best and worst products on supermarket shelves today. 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.

Best nuts for your diet

Almonds, Cashews, Pistachios

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.) 

Worst nuts for your diet

Macadamia Nuts, Pecans

Ounce for ounce, macadamia nuts (10 to 12 nuts; 2 grams protein, 21 grams fat) and pecans (18 to 20 halves; 3 grams protein, 20 grams fat) have the most calories—200 each—along with the lowest amounts of protein and the highest amounts of fats.

However, they're still good nuts: The difference between these and the lowest calorie nuts is only 40 calories an ounce. As long as you're practicing proper portion control and not downing handfuls at a time, says Caplan, any kind of raw, plain nut will give you a good dose of healthy fats and nutrients.

Walnuts

While all nuts contain heart-healthy omega-3 fats, walnuts (14 halves contain 185 calories, 18 grams fat, 4 grams protein) have high amounts of alpha linoleic acid (ALA). Research has suggested that ALA may help heart arrhythmias, 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.

Best 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.

Best nuts for disease prevention

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.

Best 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 (6 nuts) 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.

Worst snack packaging for nuts

Avoid anything in a tub

We're all for buying in bulk to save money and packaging, but it's important not to snack straight from the box (or in this case, the giant tub) when a craving hits. Beer Nuts' "original" formula—peanuts coated with a sweet and salty glaze—aren't a bad choice themselves (170 calories, 14 grams fat, and 2 grams sugar per ounce), but if you're munching on them at a party or during a "long day of game watching," as the company's website suggests, you'll likely be eating more than the recommended serving size. Not to mention, the Party Mix variety also includes M&Ms and sugary yogurt-covered raisins, for an extra calorie boost. A better bet is Beer Nuts' Original Teaser Peanut Sized bags, each containing just half an ounce of nuts.

Best nuts for your sweet tooth

Try all-natural glazed nuts

Want something sweet and satisfying but without the extra calories and high-fructose corn syrup? Look no further than Sahale Snacks glazed nuts, in flavors like Almonds with Cranberries, Honey, and Sea Salt (160 calories, 11 grams fat, 5 grams protein per ounce) or Cashews with Pomegranate and Vanilla (150 calories, 10 grams fat, 4 grams protein per ounce). They're sweetened with organic cane juice and tapioca syrup, and each contains only 6 grams of sugar per ounce. Just be careful not to eat the whole bag!

Worst nuts for your sweet tooth

Check labels for sugar content

Just because something has nuts in it doesn't make it good for you, says Caplan: "Don't justify eating a Snickers because it's got peanuts in it." Anything coated with or tucked inside layers of sugar, toffee, chocolate, or ice cream isn't going to give you much nutritional benefit, and the calories can quickly add up, she says.It's not just candy, though: Beware of seemingly healthful varieties, like Planters Sweet 'N Crunchy Peanuts. Although they still have just 140 calories and 8 grams fat per ounce, the second and third ingredients after peanuts are sugar and butter. In fact, one ounce contains 13 grams of sugar (in just a 28-gram serving size). Considering peanuts only have about 2 grams of sugar naturally, that's 11 grams of added sugar in just one handful, out of a recommended 25 for the whole 

Best nuts for a salt craving

Look for 'lightly salted'Nuts are, of course, available unsalted. But to satisfy a salty craving without going overboard, look for in-between varieties like Planters Lightly Salted peanuts, almonds, and cashews (45-55 mg sodium), or Wonderful Pistachios Lightly Salted (80 mg). Check ingredient labels, too: Some brands, like Back to Nature Salted Almonds (75 mg sodium), conta

Worst nuts for a salt craving

Steer clear of BBQ or boiled nuts

If you're watching your sodium intake, watch out for hot and spicy or barbecue flavors too. Kar's Nuts Blazin' Hot Peanuts, for example, contain 370 mg of sodium per ounce (along with 160 calories and 14 grams fat)—a whopping 15% of your daily recommended value, in just one handful!

Beware boiled peanuts, as well: This Southern treat is made by soaking fresh, raw peanuts, in their shells, in a salty brine. Sodium amounts will vary based on the exact preparation, but Margaret Holmes Peanut Patch boiled peanuts, for example, contain 390 mg per ounce.

Worst nut butter

Skip added oils and sugars

Major brands have eliminated trans fats from their nut butters, but most still contain hydrogenated oils (high in saturated fat) to increase spreadability and prevent separation. Some "natural" product lines swap hydrogenated oils for palm oil, also high in saturated fat. Skippy Natural with Honey, for example, contains 200 calories, 16 grams fat (3.5 grams saturated), and 5 grams sugar per 2-tablespoon serving.Nutella's creamy chocolate-hazelnut combo is terrific for an occasional treat—but it's hardly part of a "balanced breakfast," as its commercials say. Two tablespoons contain just 200 calories, yes, but 21 grams of sugar. In fact, sugar and palm oil are the product's first ingredients, even before hazelnuts
