Grill your way to better health

Grilled meat—in particular red meat—has garnered some negative attention from nutritionists in recent years, because in addition to its less-than-stellar nutritional profile, it’s been shown to generate potentially cancer-causing compounds when cooked over high heat. On the grill, the fat and protein in the meat produces harmful, potentially carcinogenic compounds called heterocyclic amines and polycyclic aromatic hydrocarbons. Better options are lean chicken and fish, and grilled vegetables.

How to hydrate

An estimated 40% of seniors are chronically underhydrated, and adults ages 65 and older have the highest hospital admission rates for dehydration. The main problem is that the sense of thirst diminishes with age. In addition, many people are not mindful about drinking water over the course of the day. People can increase their intake by setting up drinking routines, jazzing up drinking water, and increasing their intake of water-rich foods.

Vitamin D and the big C

New research has found an association between high and low levels of vitamin D and cancer risk. However, many older adults don’t get the recommended daily amount of 600 to 800 international units, as the main sources of vitamin D are sun exposure (which many people try to avoid) and certain foods, like fatty fish, fortified milk and cereal. Getting vitamin D levels checked to find a possible deficiency can reveal if someone needs more vitamin D, which may require taking a daily supplement.

Fruit of the month: Stone fruits

Peaches, nectarines, apricots, peaches, plums, and cherries are considered stone fruits because they all contain large, hard seeds or pits. They’re all decent sources of fiber, vitamins A and C, and potassium.

More clues about the healthiest carb choices

Diets that contain low-quality, highly refined carbohydrates (such as sugary drinks, candy, white rice, and foods made with white flour) have a high glycemic index and are linked to an increased risk of cardiovascular disease. Whole and minimally processed carbs that contain fiber and resistant starch (whole grains, legumes, nuts, and fruits and vegetables) have a lower glycemic index and are better for cardiovascular health.

High-glycemic diets could lead to big health problems

A diet consisting primarily of foods high on the glycemic index—those with high amounts of quickly digestible carbohydrates—can increase a person’s risk of cardiovascular disease and early death, suggests a study that looked at almost 138,000 people around the world.

Returning to restaurants — and to healthy eating

Many of us miss dining out. Now that restaurants are offering indoor and outdoor dining again, it's tempting to cut loose and order restaurant meals without thinking about nutrition. But if you're trying to stick to a healthy diet, try these tips when you're out in a restaurant.

Using weight loss or sports supplements? Exercise caution

Magical claims are made in ads for dietary supplements marketed to enhance well-being and solve health problems. But the reality is that most do little or nothing to improve your health, and in some cases weight loss or sports supplements might actually harm you.

By the way, doctor: Is spirulina good for you?

I read that spirulina is the next wonder vitamin. What can you tell me about it?

Potassium and sodium out of balance

The body needs the combination of potassium and sodium to produce energy and regulate kidney function, but most people get far too much sodium and not enough potassium.
