Healthy eating for older adults Archive

Your salt shaker usually isn't the worst culprit. Instead, check your condiments, sauces, and spice blends, many of which are high in sodium.

For decades, health experts — especially cardiologists — have been telling people to eat less sodium, one of the main components of salt. Most Americans still consume far too much of this mineral, which raises blood pressure and the risk of heart disease.

Despite these warnings, the average sodium intake in this country is around 3,200 milligrams (mg) per day. That's about 30% more than is recommended by the federal dietary guidelines, which advise people to limit their daily sodium to 2,300 mg. And it's more than twice the target suggested by the American Heart Association of 1,500 mg per day.

These shiny, reddish or golden-brown seeds are the richest natural source of alpha linolenic acid (ALA), an omega-3 fatty acid that's also found in soybean oil, canola oil, and walnuts. Because our bodies can't make omega-3 fats, we must get them from food. The other main omega-3s, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are found mainly in fatty fish. Nutrition experts recommend getting at least one rich source of omega-3 fats daily. So if you don't eat fish, flaxseeds are a good option.

Flaxseeds, which have a slightly nutty taste, contain other healthful nutrients, including protein, fiber, and lignans (plant chemicals with antioxidant effects). Small studies suggest that consuming whole or ground flaxseeds may lower cholesterol levels and blood pressure.

Research we're watching

People who eat chili peppers on a regular basis appear to lower their risk of dying from heart disease, a new study finds.

Researchers analyzed the diets and health records of more than 22,000 people living in southern Italy and followed them for a median of just over eight years. People who ate chili peppers more than four times a week were about one-third less likely to die of heart disease than those who rarely or never ate the spicy-hot peppers. This protective benefit was evident regardless of whether people followed a Mediterranean-style diet (which is often recommended for heart health) or a less healthful diet.

Catching a ride to the doctor or grocery store has never been easier, thanks to rideshare services like Uber or Lyft. You simply download an app to your smartphone and enter your credit card information. Then you can just tap a button whenever you need a ride. But if you're not comfortable with the concept, take heart: the United States now has about a thousand rideshare services that cater to older adults, according to a CDC-funded study conducted by NORC, a nonprofit research organization based at the University of Chicago. The results were released Dec. 5, 2019. Researchers found more than 900 individual nonprofit rideshare services and three for-profit rideshare companies (with a total of 888 locations) available for older adults in the United States. The rides weren't just for doctor or grocery store visits. Many rides were for other errands, work, or fun (an important point, since older adults are at risk for isolation). Also appealing: about two-thirds of the rides were free, and about a third of the services provided help in and out of the vehicle. Want to give it a try? Contact your local Area Agency on Aging (www.health.harvard.edu/aaa) to find groups that offer rides for older adults.

The FDA is urging consumers to use caution with products infused with cannabidiol (CBD), the cannabis-derived extract that's touted as a cure-all. CBD is widely available in creams, tinctures, oils, patches, gummy bears, capsules, and more. But some products are being sold illegally, with claims that CBD can treat health conditions. In November, the FDA cracked down on 15 companies that were making such claims, or that were illegally adding CBD to food or selling it as a dietary supplement. "We remain concerned that some people wrongly think that the myriad of CBD products on the market, many of which are illegal, have been evaluated by the FDA and determined to be safe, or that trying CBD can't hurt.' Aside from one prescription drug approved to treat two pediatric epilepsy disorders, these products have not been approved by the FDA, and we want to be clear that a number of questions remain regarding CBD's safety," says FDA Principal Deputy Commissioner Amy Abernethy. Even legal CBD products have potential health risks such as liver injury, drug interactions, sedation, diarrhea, decreased appetite, and mood changes. Talk to your doctor before trying any new supplement, especially if it contains CBD.

The Nutrition Facts label that appears on packaged foods has been updated to provide consumers with more thorough information, and also to more accurately reflect typical consumption habits.

There is a lot you can do to lower your chances of having a stroke. Even if you've already had a stroke or TIA ("mini-stroke"), you can take steps to prevent another.

Controlling your weight is an important way to lower stroke risk. Excess pounds strain the entire circulatory system and can lead to other health conditions, including high blood pressure, diabetes, high cholesterol, and obstructive sleep apnea. But losing as little as 5% to 10% of your starting weight can lower your blood pressure and other stroke risk factors.

Between 1959 and 2014, average life expectancy in the United States rose astoundingly by nearly a decade. Then it began declining. A recent report examining this situation raises tough questions about that unexpected change.

There is ample evidence to support the healthfulness of a vegan diet. However, those who choose vegan eating may not get enough of some nutrients unless they pay careful attention to their food intake, or choose to take supplements.
