8 superfoods to help weight, diabetes, memory and more

There’s a reason why you should splurge on that Brie after dinner or pour whole milk into your coffee. People who ate the most high-fat dairy products (like yogurt and cheese) had about a 50

percent lower risk of developing type 2 diabetes than those who ate the least, according to a 2016 Harvard study published in the journal _Circulation_. And contrary to popular belief,

recent research has found no link between eating full-fat dairy and an increased risk of heart disease.  “It’s thought that some of the fatty acids in full-fat dairy products may actually be

protective against both heart disease and type 2 diabetes,” explains Reinhard. “In addition, it may be that people feel more satisfied with full-fat dairy, so they’re less likely to

compensate by eating more high-calorie carbohydrates, such as cereals, breads and pasta.” HOW TO EAT IT: treat yourself to up to one serving of full fat dairy a day. “You don’t want to make

all of your dairy full fat, as it does have more calories,” advises Reinhard. iStockphoto SARDINES A whole can has under 200 calories, is packed with over 20 grams of protein, and serves as

an excellent source of bone-building calcium (more so than a cup of milk!), energizing B12 and immune-boosting vitamin D, says Blatner. And the rich, oily fish is also full of omega-3 fatty

acids, which research suggests may help bust stress, boost memory and reaction time, and increase brain gray matter (the tissue associated with higher intelligence), she adds. One 2016

Spanish study found that patients with type 2 diabetes who ate the equivalent of a 3.5-ounce can of sardines five days a week had higher levels of adiponectin, a hormone that helps fight

inflammation in the body and reduces risk of heart disease. HOW TO EAT THEM: Blatner recommends just opening the can, draining them, squeezing in some fresh lemon juice and chopped fresh

parsley, mashing it all together and digging in. You could also pair sardines with crackers, olives or a simple salad. iStockphoto KALE Once a superfood, always a superfood. One cup of

chopped kale has just 30 calories but provides more than 130 percent of your daily vitamin A and C needs — nutrients critical for a healthy immune system and healthy skin, both of which

decline with age, notes Sass. And the leafy green's vitamin K helps maintain strong bones, as does the nearly 100 mg of calcium per serving it contains. “Kale also contains natural

substances that protect the bends and branches of blood vessels — areas most prone to cholesterol buildup and inflammation — making it a potent protector of your heart,” she adds.

What's more, a 2015 Rush University study found that seniors who ate one to two servings of leafy greens such as kale each day had the cognitive ability of someone 11 years younger than

those who consumed none. It’s thought that vitamin K, lutein, folate and beta-carotene could be the keys for such brain health benefits, says Sass. HOW TO EAT IT: You can always throw some

into a smoothie or build a salad around it, but a supereasy and tasty way to enjoy kale is it to make it into chips, suggests Blatner. Take two bunches of kale (about 14 large leaves), toss

them with 2 teaspoons of olive oil, place them in a single layer on a baking sheet, sprinkle them with nutritional yeast (a healthier version of parmesan) and sea salt, and bake for 18

minutes at 300 degrees Fahrenheit, until crisp. AVOCADO These fruits are chock-full of heart-healthy monounsaturated fat, which has been shown to improve cholesterol. People who eat an

avocado a day have lower levels of the bad cholesterol, LDL, and higher levels of the good kind, HDL, than those who eat a similar diet without any, according to a 2015 study published in

the _Journal of the American Heart Association_. Avocados are also packed with disease-fighting antioxidants and nearly 20 vitamins and minerals, including vitamins E and K, magnesium and

potassium, notes Sass. And a review of studies published last year found that avocados help reduce the risk of developing metabolic syndrome — a cluster of risk factors such as high

cholesterol, blood sugar, blood pressure and an increased body mass index that raise your risk of developing both type 2 diabetes and heart disease. HOW TO EAT IT: Let’s face it: You can

never get too much guacamole, especially when you're scooping it up with other healthy foods like baby carrots and red peppers. But you can also throw a couple of slices on top of your

sandwich, salad or eggs, or puree avocado and throw it into soup, says Heller.
