New phrases showing up on packaging don't always tell you if the food is better for your health.

You're not alone if you don't know the meaning of certain terms on food labels lately. A new language has developed to describe healthy ways to produce meat, vegetables, fruit, and other products in the grocery store. "It's not just the terms that are confusing, but also various associated health claims," says Vasanti Malik, a nutrition researcher at the Harvard T.H. Chan School of Public Health.

Organic vs. natural

Some food is labeled "organic" or "natural." What's the difference? The FDA doesn't have a definition for "natural," although it doesn't object to the term if a food does not contain added color, artificial flavors, or synthetic substances.

It's easy enough to look up how much vitamin C or calcium you should get each day. It is also easy to read the back of a vitamin bottle to see just how much of a given vitamin or mineral the product provides. But how can you tell if what you eat — which should be your primary source of important nutrients — is giving you what you need?

One way is to focus on the big picture: eat a balanced diet that contains a variety of colorful fruits and vegetables, whole grains, beans, nuts, dairy products, seafood, lean meats, and poultry. Focus on nutrient-dense foods like these, which are packed with vitamins and minerals relative to the number of calories they deliver, and you should be fine.

What if men approached their health at midlife the same way that financial experts advise them to plan for retirement? Some of the same rules apply: take a close look at where things stand now, and then take steps to protect your future. Midlife is a good time to lower health risks and invest for long-term health benefits.

How? First, acknowledge what you can't control. Then put your energies into changing what you can — for the better.

Research suggests that moving out of your comfort zone is the key to staying mentally and physically young.

Finding role models who are older than we are gets more difficult as we age. But in the last few years, medical science has identified a new group we can aspire to join — the super-agers. The term refers to people in their 70s and 80s who have the mental or physical capability of their decades-younger counterparts.

What makes a cognitive super-ager?

Dr. Bradford Dickerson, a neurologist at Harvard-affiliated Massachusetts General Hospital and his colleagues have been studying super-agers for several years. Their results suggest that embracing new mental challenges may be the key to preserving both brain tissue and brain function.
