Celiac disease and gluten sensitivity

Celiac disease is an allergic reaction to gluten protein in food that causes symptoms like nausea, diarrhea, and bloating. Non-celiac gluten sensitivity causes similar symptoms to celiac but is not an allergic reaction and does not cause permanent intestinal damage.

There are no proven health benefits of eating a gluten-free diet unless a person is allergic or sensitive to gluten. (Locked) More »

Protein check: How much do you really need?

It’s unclear how much protein is essential as people get older. It’s best to follow the current Recommended Dietary Allowance for protein intake, which is 46 grams per day for women and 56 grams for men. As for the type of protein, mounting evidence shows that reducing animal-based proteins and increasing plant-based proteins is a healthier way to eat.

Can drinking wine really promote longevity?

Research on resveratrol may someday lead to improved health and extended life. However, it appears that there is no link between dietary resveratrol levels and the rates of heart disease, cancer, and death in humans. Taking resveratrol supplements comes with some risks. The safe, effective dose for humans is unknown. It is also unknown how long-term use will affect people for better or for worse.

Must-haves from the produce aisle

The summertime brings a bounty of fruits and vegetables that can boost health. Blackberries have only 60 calories per cup, and they are high in fiber, vitamin C, and vitamin K. Zucchini are high in vitamin C and are a good source of B vitamins and potassium. Sweet red peppers are loaded with vitamins C and A, as well as plenty of fiber, vitamin B6, and folate. Swiss chard is rich in sulforaphane, isocyanate and indoles, which counteract the effects of carcinogens—cancer-causing chemicals.  (Locked) More »

Is summer heat putting you at risk?

High temperatures put older adults at risk for heat-related illness, because the body can no longer handle heat and dehydration the way it used to. Symptoms of heat exhaustion include general weakness with dizziness, fatigue, nausea, and feeling faint. To avoid heat exhaustion, people should stay out of the heat, make sure there’s an air conditioner that works at home, stay hydrated by drinking two to three quarts of liquid per day, go outside only in the morning or late afternoon, and wear loose, light-colored clothing.

Restaurant meals: How to make them healthier

Eating in restaurants can ruin the healthiest diets. But one can enjoy a meal on the town by following a few guidelines. Suggestions include reducing portion sizes by splitting an entrée with a dinner partner, asking for food to be steamed or broiled without added butter, requesting that the chef go easy on added salt, asking for sauces on the side, and planning what to order ahead of time by looking at a restaurant’s menu online or visiting the restaurant in advance to check out the offerings.  More »

What too much sugar could do to your heart

Sugar not only leads to weight gain, but also can contribute directly to cardiovascular disease. Research finds people who get 25% of their daily calories from sugar nearly triple their risk of death from heart disease. The American Heart Association recommends that women get no more than 100 of their daily calories from sugar, and the World Health Organization recently lowered its recommendation to no more than 5% of calories a day.
