Question 1 of 20 Correct

What's the healthiest preparation for nuts?

Correct! Sorry, that’s incorrect.

The correct answer is: Raw and unsalted: that's the best way to go nuts. When heated, as in roasting or drying, nuts can lose up to 15 percent of their healthy oils. Can't find raw, or just not a fan? Toast and roast your own -- you can control the temperature. Or look for nuts that are roasted without added fats or salt.

Your body needs a steady supply of protein to preserve your lean body mass (without protein, your body will begin tearing down your lean body mass for fuel). How many grams of protein are in a quarter cup of nuts?

Correct! Sorry, that’s incorrect.

The correct answer is: With the exceptions of pecans and macadamia nuts, a quarter cup of nuts packs between 5 and 10 grams of protein. Enjoy small portions of nuts as a snack or with a meal to keep your protein intake at sufficient levels.

Question 3 of 20 Correct

What effect do nuts have on cholesterol?

Question 4 of 20 Correct

True or false: A person who is allergic to peanuts is also likely allergic to all other nuts.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. Peanuts are technically a legume, so being allergic to peanuts fortunately does not mean you must swear off tree nuts. Check with your allergist.

Question 7 of 20 Correct

Which of these foods, despite its name, is not actually a nut?

Correct! Sorry, that’s incorrect.

The correct answer is: Despite their "nutty" names, none of these are actually nuts. In some circles, the coconut is considered a nut, but it's also categorized as a seed or even a fruit. Nutmeg is a seed, and water chestnuts are the edible portion of a root plant.

Question 8 of 20 Correct

True or false: Peanut and nut butters do not offer the same health benefits as nuts themselves.

Question 9 of 20 Correct

People with a history of what health condition should avoid nuts?

Question 10 of 20 Correct

Diabetics may want to eat two ounces daily of which of these nuts to improve heart health?

Correct! Sorry, that’s incorrect.

The correct answer is: All of the above. One recent study found that eating two ounces of mixed nuts per day, including peanuts, almonds and walnuts, improved blood sugar control and LDL in people with diabetes. Not a fan of mixed nuts? Some research shows that walnuts and almonds individually can help with blood sugar control as well.

Question 11 of 20 Correct

Question 12 of 20 Correct

Just one of these nuts each day gives you all the selenium you need for the week.

Correct! Sorry, that’s incorrect.

The correct answer is: Eat one Brazil nut each day, and you'll get your fill of selenium. Our bodies need 55 to 70 micrograms each day; a Brazil nut averages about 70 to 90 micrograms of selenium per nut.

Nuts About Nuts
Question 13 of 20 Correct

True or false: The only health downside to Brazil nuts is their high calorie content.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. Brazil nuts contain a lot of calories, as do all nuts, but that's not the only health concern associated with these guys. Consuming just 3/4 of an ounce per day of the selenium-rich nut can lead to selenosis, or selenium toxicity. Symptoms of the toxicity include garlic-scented breath, hair loss and fatigue. You should only eat Brazil nuts occasionally because of their very high selenium content.

Nuts About Nuts
Question 15 of 20 Correct

A recent study found that which of these nuts has fewer calories than once thought?

Correct! Sorry, that’s incorrect.

The correct answer is: Pistachios may have fewer calories than we previously thought. One study from July 2011 discovered that the human body isn't capable of absorbing some of the fats in pistachios, which reduces the calorie load. Pistachios may have as much as six percent fewer calories than originally thought.

Question 16 of 20 Correct

Which of these helps promote sleep?

Nuts About Nuts
Question 17 of 20 Correct

Which is healthier: Regular peanut butter or low-fat peanut butter?

Correct! Sorry, that’s incorrect.

The correct answer is: When you take fat out of peanut butter, you lose flavor. Peanut butter manufacturers often add extra sugar to make up for that diminished flavor. That's why it's healthier to eat regular peanut butter -- in moderation, of course.

Nuts About Nuts
Question 18 of 20 Correct

True or false: Eating peanuts while pregnant can help your child avoid a peanut allergy.

Correct! Sorry, that’s incorrect.

The correct answer is: This is false. American researchers studied women who ate peanuts while pregnant to see if their peanut consumption affected their unborn child's allergy risk. In short, it does, and negatively: Babies whose mothers ate the greatest number of peanuts or peanut products while pregnant were more likely to test positive for allergic factors related to a peanut allergy. (The study did not definitely diagnose the children with a peanut allergy, only the likelihood that they would develop one.)

Nuts About Nuts
Question 19 of 20 Correct

Just two of which nuts have the same number of calories as an egg?

Correct! Sorry, that’s incorrect.

The correct answer is: Just two Brazil nuts nets you 66 calories -- about the same amount as an egg.

Nuts About Nuts
Question 20 of 20 Correct

True or false: Nuts can help you lose weight.

Correct! Sorry, that’s incorrect.

The correct answer is: This is true. Even though they're high in calories, nuts may actually help you lose weight, because they help you feel fuller longer, which reduces snacking or overeating. The sins of the calories are also reduced when you take into account how much good the unsaturated fats and vitamins and minerals do for your body.
