The best dietary strategy when it comes to carbohydrate intake could be neither high-carb nor low-carb, but rather moderation. A study published online August 16 by The Lancet Public Health found that both high- and low-carbohydrate diets were associated with earlier death. But people who got about half to 55% of their calories from carbohydrates — which is considered a moderate amount — lived longer.

The research involved more than 15,000 adults ages 45 to 65 who were involved in the Atherosclerosis Risk in Communities study. Participants filled out a dietary questionnaire when they enrolled in the study, which began in 1987. Researchers then looked for links between what participants ate and their death from any cause over a median follow-up period of 25 years.

The Internet is rife with dubious dietary advice for heart health. Here's how to separate the wheat from the chaff.

Surfing the Web nearly always involves running into a few ads, blogs, and articles about diet and health. Perhaps you also have relatives or friends who send you links about what you should (or shouldn't) be eating to lose weight, lower your blood pressure, or dodge heart disease.

You might be skeptical enough to avoid clicking on suspicious links, like those once-popular ads promising "one weird trick to banish belly fat." Yet sometimes the advice appears to be from a legitimate source — for instance, a purported world-class heart surgeon who's written books about diet and nutrition. But what if the recommendations run counter to what you've mostly heard about a heart-healthy diet? It's no wonder many people feel confused and frustrated about nutrition.

Just a few years ago, cauliflower was considered kind of ho-hum, relegated mainly to frozen vegetable medleys or crudité platters. But these days, the mild white vegetable is far more popular, thanks to its versatility as a carbohydrate substitute. Recent diet trends that encourage people to eat fewer starchy and grain-based foods likely contributed to cauliflower's rise.

Even if you're not avoiding carbs, using cauliflower as a substitute for starchy foods such as rice is a good way to cut calories and eat more fiber. You can also make mashed cauliflower instead of mashed potatoes (see www.hsph.harvard.edu/nutritionsource/mashed-cauliflower). Or try making a pizza with one of the many cauliflower-based pizza crusts now available in most grocery stores.

People with heart disease who eat a traditional Southern diet (rich in meat and fried foods) may be more likely to die sooner than people who follow a plant-based Mediterranean-style diet.

So says a study in the July 12 Journal of the American Heart Association that focused on people with a history of heart disease, such as a heart attack or bypass surgery. Researchers conducted dietary assessments on 3,562 people ages 45 and older and tracked them for about seven years.

Lost your spark and gusto? These strategies can help you recharge.

Everyone has the occasional low-energy day when you are easily fatigued. Often the feeling passes, and you bounce back to your regular robust self. But if you struggle with a constant lack of energy, you may have a problem deep within your cells.

Mitochondria are the power source inside all your body's cells. These tiny structures fuel the body by producing molecules called adenosine triphosphate or ATP. However, as you grow older, your body has fewer mitochondria.
