As some artichoke aficionados know, anything you eat or drink right after eating this unique vegetable tastes sweeter than usual. Artichokes contain chlorogenic acid and cynarin, which partially inhibit the sweet receptors on your tongue. Whatever you eat or drink right afterwards washes off the compounds, fooling your brain into perceiving sweetness that isn't actually there. Try serving an artichoke alongside another vegetable you find less palatable, and alternate bites!

Cynarin also seems to increase the liver's production of bile, which helps remove cholesterol from the body.

Q. I have read that vitamin K supplements can help prevent heart disease. Should I take them?

A. Vitamin K — which is found in high levels in green leafy vegetables like spinach, kale, and romaine lettuce — plays a role in helping the body make blood clotting proteins. Although some observational studies have suggested a heart benefit from diets high in vitamin K, studies of supplements have not shown a protective effect.

Here's some encouraging news about how many sugary drinks we're guzzling in the United States: an observational study led by Harvard researchers, published online Nov. 14, 2017, by Obesity, suggests that consumption of sugar-sweetened beverages fell significantly between 2004 and 2014. Researchers looked at data collected from more than 18,000 children and teens and more than 27,000 adults ages 20 or older. Every two years, people were asked about the kinds of drinks they'd had in the previous 24 hours, such as soda or juice. About 60% of kids and 50% of adults reported drinking a sugary beverage on any given day in 2014, down from 80% of kids and about 62% of adults in 2004. The percentage of adults ages 60 or older who reported drinking a sugary beverage on any given day dropped from 46% in 2004 to 39% in 2014. While the declines are a step in the right direction, consumption of these drinks was still highest among those at higher risk for obesity, such as African American and Hispanic participants (across all age groups). Remember: the average can of soda has about 40 grams of added sugar, far more than the American Heart Association's recommended limit of 24 grams of added sugar per day for women, and 36 grams per day for men. Consuming too much added sugar is associated with weight gain and an increased risk for developing type 2 diabetes and a heart attack.

Despite their striking colors — ruby red, golden yellow, and even candy-striped — beets aren't exactly the most popular vegetable on the block. But what if you make them sound more enticing? It turns out that people may eat more "dynamite chili and tangy lime-seasoned beets" than plain old "beets."

In a study done at a Stanford University cafeteria, researchers found that people ate about 25% more vegetables if the selections were described in indulgent terms rather than basic or healthy terms (such as "lighter-choice beets with no added sugar") even though all the dishes were prepared exactly the same way. Other examples of indulgently named veggie dishes included "zesty ginger-turmeric sweet potatoes" and "sweet sizzlin' green beans and crispy shallots." So if you're hoping to entice friends or family to try beets (or other vegetables), add some appealing adjectives to the description.

Eating nuts has been linked with a lower risk of heart disease. Now, the largest study to date on the subject suggests that regular consumption, and not any specific nut, offers the greatest benefit. The research, published online Nov. 13, 2017, by the Journal of the American College of Cardiology looked at more than 210,000 people who shared information on their eating habits and health over a 32-year period.

The results showed that those who ate nuts — such as peanuts or tree nuts like walnuts, almonds, and cashews — on a daily basis had a much lower risk of developing cardiovascular disease or coronary artery disease compared with people who rarely or never ate nuts.

Even if you can't, you can still substantially reduce your risk of heart attack and stroke through lifestyle changes and certain medications.

In your 20s, maybe you sometimes chose fast-food burgers and fries over healthier foods. Perhaps in the decades that followed you pursued a series of fad diets, questionable lifestyle choices, and too many days when you skipped your workout in favor of the couch.

You're now repenting for the sins of the past, but the question is, can you undo the damage? Can you unclog clogged arteries (otherwise known as atherosclerosis) and reduce your risk of heart disease in the process?

If you’re like most Americans, you aren’t eating enough fruits and vegetables, according to the CDC. A study published in the CDC’s Nov. 17, 2017, Morbidity and Mortality Weekly Report shows only about one in 10 adults meets federal recommendations, which call for most women to eat 1.5 cups of fruit and between 2 and 2.5 cups of vegetables each day.

"In 2015, just 9% of adults met the intake recommendations for vegetables, ranging from 6% in West Virginia to 12% in Alaska. Only 12% of adults met the recommendations for fruit, ranging from 7% in West Virginia to 16% in Washington, D.C.," reported the CDC.

You might be surprised to learn that what you eat affects your ability to move.

• The nutrients in the food you eat help your body build bone, power muscle, repair and replace tissues, and keep your brain active and your heart pumping.
• Your diet also influences your chances of developing chronic diseases such as type 2 diabetes, heart disease, and osteoporosis — all of which can compromise your well-being and hinder your ability to live an active and independent life.
• Eating the right foods is important, but so are how much you eat and how well you balance the calories you take in with those you burn off. Simply being overweight can make it more difficult to move easily in your day-to-day activities.

Keys to healthy eating

There is no shortage of diet books and healthy eating plans that claim to help you slim down and live a longer and healthier life. But healthy eating is surprisingly simple.
