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.

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.

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.

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.

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?

Expand your healthy cooking oil choices

The healthiest fats for cooking and using on food come from plants. Plant oils consist mostly of unsaturated fat, which in limited amounts is good for the heart. One can enjoy a wide variety of plant oils, such as avocado, canola, corn, flaxseed, grapeseed, olive, peanut, rice bran, safflower, soybean, sunflower, and walnut oils. But high heat can break down plant oil molecules and reduce health benefits. The most fragile plant oils include extra-virgin olive oil and nut oils, such as walnut oil.

Fruit of the month: Berries

Strawberries and blueberries are rich in beneficial plant compounds known as anthocyanins, which give berries their vibrant red, blue, and purple hues. Several studies have linked diets with anthocyanin-rich foods to better heart health.

Are you wasting money on supplements?

Taking multivitamins doesn’t prevent heart attacks or strokes, and most dietary supplements (such as fish oil, red yeast rice, and coenzyme Q10) offer no or limited benefits for avoiding heart-related problems. For people who don’t have heart disease, eating two servings of fatty fish weekly or following a healthy vegetarian diet rich in nuts, legumes, and healthy oils makes more sense than spending money on over-the-counter fish oil supplements. People with heart disease would be better off asking their doctor about the prescription drug icosapent ethyl (Vascepa), a high-dose, purified EPA that lowers cardiovascular risk when taken with a statin.
