lder citizens looking for an activity that will help bolster whole-person health — physical and mental — might want to start by getting their hands dirty.

That’s the message from Janice Gregg of the Oregon State University Extension Office in Linn County, who’s planning to teach a pair of classes this month on “Gardening for Healthy Aging.” “What can gardens contribute to our health and our quality of life?” Gregg asked in a recent interview as she prepared to teach the free two-hour classes. (See the box for class dates and times.) The answer: Plenty, regardless of whether the gardener is working on a big plot of land or smaller sites. Gregg said the benefits of gardening can be useful even if participants are tending to a simple raised bed or even just a handful of pots. The gardening work can be great for the body. But it also has plenty to offer the mind and soul as well, she said. She noted, for example, studies that show “if you work in a garden, you’re better able to cope with stress and life’s challenges.” “Gardening can contribute to all of these aspects of health and wellness,” she said. And gardens also give outlets for creativity and social interaction with others. One of

OSU extension’s Jancie Gregg talks about healthy gardening activities.

Like any physical activity, gardening can involve some exertion. Here are some tips on how to avoid injury: • Use raised beds or pots so you don’t have to bend your back so much. • Use tools with long handles. • Garden early in the morning or later at night so that you’re not working in the heat of the day. • Just as you would before any physical activity, warm up before and after. Your muscles don’t have to be sore after a day of gardening. • Carry a whistle or a cellphone with you just in case you need assistance.

the keys to the success of the long-running Master Gardeners program, Gregg said, is its social component. But you don’t need to be a Master Gardener to start enjoying the activity. Beginners, for example, could start planting herbs in pots or a small raised bed.

Calcium: Get it from food, not pills Evidence suggests supplements may damage heart while helping bones BY GISELA TELIS THE WASHINGTON POST

When a 2012 study in the journal Heart found that calcium supplements might raise your risk of a heart attack, I was more than a little alarmed. Might the overthe-counter supplements I’d been taking to strengthen my bones be damaging my heart? The answer: Maybe. “Over the last five years, there have been some studies to suggest that taking a calcium supplement raises blood calcium levels and could precipitate into the arteries,” says Felicia Cosman, senior

clinical director of the National Osteoporosis Foundation and author of “What Your Doctor May Not Tell You About Osteoporosis.” “But this whole line of evidence is very controversial, and I think the jury is still out.” What isn’t controversial is calcium’s important role in overall health: Your body needs it to maintain heart and nerve function and to build and keep strong bones. The Institute of Medicine recommends that most adults get 1,000 to 1,200 milligrams a day. But as for meeting your daily requirement in whole or in part by taking supplements, there’s a lot of conflicting evidence. The 2012 Heart study and an earlier study in the journal BMJ both suggested links between calcium intake and heart attacks, but the latter study also found that getting too little

calcium can contribute to heart disease. The same ambiguity goes for kidney stones, another side effect of calcium supplements. A large 2006 study in the New England Journal of Medicine found that women taking a 1,000-milligram calcium supplement were more likely to develop kidney stones than women taking a placebo. But an even larger study in 2004 found that overall dietary calcium intake actually reduced kidney-stone risk. It’s confusing, even for doctors. But there’s a common thread: None of the heart or kidney risks was associated with calcium from food. That has changed how many physicians advise their patients, Cosman says, and it has brought their focus back to what their patients eat. “We want people to concentrate

on modifying diet wherever possible,” Cosman says. “Most of the data show that dietary calcium is better for you and your bone integrity, so if you can get the calcium you need through your diet, you shouldn’t take a calcium supplement.” Considering the abundance of calcium-rich and calcium-fortified foods out there, getting enough calcium from diet alone isn’t hard. Some breakfast cereals offer as much as 1,000 milligrams in a single serving. Unless you have a medical condition (such as celiac disease) that impairs your ability to absorb nutrients, eating a varied, healthful diet that includes calcium-rich foods such as milk and yogurt should do the trick, Cosman says — no supplements required.

The three leading causes of death among Americans in 2000 were all behaviorrelated (tobacco use contributed to 18.1 percent of deaths that year, poor diet and exercise habits played a role in 16.6 percent of deaths, and alcohol was a factor in 3.5 percent of deaths), according to data from the Centers for Disease Control and Prevention. Two health policy experts from Harvard University wanted to find out how the public was responding to what they called “new frontier” public health initiatives aimed at changing consumer behavior, such as New York City’s ban on super-sized sodas. Stephanie Morain and Michelle M. Mello conducted an online survey of 1,817 Americans, asking them about a variety of policies. Overall, 75 percent said the CDC was doing a “good” or “excellent” job, and more than half gave the same ratings to their state and local public health agencies. When it came to assessing the government’s public health agenda, there was broad support for preventing cancer (89 percent were in favor), preventing heart disease (86 percent), preventing obesity in children (81 percent) and adults (76 percent), preventing and reducing tobacco use (76 percent) and reducing alcohol consumption (70 percent). In addition, 84 percent agreed that the government should help people with diabetes control their disease. — Los Angeles Times

Safer oysters possible with less bacteria Oregon State University has improved an old method of making oysters safer to eat so that more bacteria are removed without sacrificing taste and texture. The improved process nearly clears their digestive tracts of the bacteria Vibrio parahaemolyticus, which can cause gastroenteritis, an infection marked by severe abdominal pain, vomiting and diarrhea. Each year in the United States, more than 40,000 cases of Vibrio parahaemolyticus infection are linked to the consumption of seafood. “This bacteria is a huge safety concern,” said YiCheng Su, an OSU professor of seafood microbiology and safety. “Cooking oysters easily kills it, but many consumers want to eat raw shellfish without worrying about foodborne illness.” To make oysters safer, processors place the mollusks in tanks of clean seawater at room temperature, a method known as depuration. The shellfish filter clean water through their system and excrete most bacteria from their digestive tracts into the water. Seeking a better alternative, Su and his colleagues tweaked the depuration method. — Oregon State University

HIV: Progress made, but not enough A 20-year-old diagnosed with HIV or AIDS today can expect to live 50 years, due to groundbreaking advances in treatment since the discovery of the virus 30 years ago. Despite the progress, troubling trends remain: 47,500 new cases of HIV infection are diagnosed each year in the U.S. — The Record (Hackensack,N.J.)
