Weight-related stroke risk varies for different stroke types, analysis finds

In an observational study of 1.3 million women, excess weight was linked to an increased risk of strokes caused by blood clots but a lower risk of strokes caused by bleeding. 

There’s no sugar-coating it: All calories are not created equal

The view that calories are calories regardless of their source has been shown to be outdated. Foods with a low glycemic index are better because they tend to raise blood sugar more slowly, and they are also more likely to be healthier foods overall. By choosing the low-glycemic foods and thus the minimally processed foods, people can lose more weight, feel fuller longer, and remain healthier.

Can I substitute nuts for animal protein?

Nuts are a good source of plant fats and protein, but they are high in calories. It’s a good idea to limit nut consumption to 1 ounce per day.

Is eating dried fruit healthy?

Ask the doctor

Q. I love dried fruit and thought it was healthy. But I hear that you gain a lot of weight eating dried fruit, which is not healthy. What's the truth?

A. The truth is that the actress and comedian Mae West was wrong when she allegedly said "Too much of a good thing ... can be wonderful!" Food contains calories, and eating too many calories-even of healthy foods-leads to weight gain. But there are healthy calories and unhealthy ("empty") calories, and fruit is a healthy source of calories. That's as true of dried fruit as fresh fruit.

Why will the new food labels highlight added sugars?

The new Nutrition Facts labels will list “added sugars” in a serving of food. Until the labels appear, one should look for sugars such as dextrose and sucrose on a label’s list of ingredients.

How to avoid the health risks of too much salt

Stick to fresh foods, and fill your salt allotment from healthy sources like whole-grain breads.

As we reported in August 2016, the FDA is encouraging the food industry to cut back on added sodium in commercially processed and prepared food. It's a good reminder for all of us that too much salt in the diet is risky for health. How much is too much? "It's controversial, although I don't think anyone is in favor of unlimited salt intake," says Dr. Randall Zusman, a cardiologist with Harvard-affiliated Massachusetts General Hospital.

Salt risks

How much is too much?

So what's the controversy about? It centers on how much salt is safe for consumption, and it's still being debated. The American Heart Association recommends a limit of 1,500 milligrams (mg) per day. The FDA recommends a limit of 2,300 mg of sodium per day. The U.S. Dietary guidelines used to recommend a limit of 1,500 mg per day for a wide swath of people (everyone 51 and older, all African Americans, and anyone with high blood pressure, kidney disease, or diabetes), but this year changed it to 1,500 mg per day only for people with high blood pressure, and 2,300 mg for everyone else.

Common sources of sodium

What you should do

It's best to avoid processed food. Choose fresh, frozen (no sauce or seasoning), or no-salt-added canned vegetables, and opt for fresh poultry, seafood, and lean meat, rather than processed meat and poultry.

Krivitsky recommends limiting sodium to 500 or 600 mg per meal, and making sure it comes from healthy sources, like whole-grain breads and cereals.

How can you find out about sodium content? Start reading Nutrition Facts labels. You really can find low-sodium options. For example, one cup of Post Shredded Wheat has no sodium, and half a cup of Prego No Salt Added pasta sauce has just 40 mg of sodium.

Krivitsky also recommends ditching saltshakers and flavoring food instead with spices, such as cumin, rosemary, basil, ginger, or dill; flavored vinegars; and lime or lemon juice. "Low salt doesn't mean less flavor," points out Krivitsky. "It just means less salt."

How about a salt substitute?

When you want to add something salty to food, a salt substitute may do the trick. Substitutes are made from potassium chloride, which is similar to table salt (sodium chloride).

Substitutes fall into two categories: low-sodium or "light" salt, which replaces up to half of the sodium chloride with potassium chloride, and no-sodium or "salt-free" salt, which contains only potassium chloride.

For some people, potassium chloride can leave a bitter aftertaste. People with certain types of heart or kidney disease, or taking certain potassium-retaining medicines, may be told to avoid potassium-based substitutes. For others, potassium chloride is advisable: it not only helps avoid excess sodium, but also helps lower blood pressure.

 

 

 

Higher BMI linked to early death

A large international study published Aug. 20, 2016, in The Lancet suggests that an unhealthy body mass index increases the risk of early death.

Less than 1 in 10 teens gets enough exercise: What this means for them and says about us

Teens don’t exercise enough, and with a third of U.S. adults classified as obese, it’s important that exercise is encouraged in children and teens. Starting healthy habits when they’re young keeps kids healthy into adulthood. Studies show that obese adults rarely lose the weight, so it’s better to keep the weight off in the first place. A lot has to do with our biology but also our lifestyle, and we can change the latter. So let’s get our children and teens moving.
