Salty Foods Can Age Overweight Teens’ Cells

The salt contained in the junk foods and fast foods so many overweight and obese teens consume may be aging their cells, a process that can lead to heart disease. A study presented at this year’s American Heart Association’s Epidemiology & Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions found that the protective ends of chromosomes (telomeres), which normally shorten with age, were significantly shorter in overweight and obese teens whose sodium intake was high compared to teens who consumed less sodium. In normal weight teens, sodium consumption didn’t affect telomere length. Obesity is associated with increased levels of inflammation, which also speeds telomere shortening, and carrying extra pounds appears to boost sensitivity to salt. The findings suggest that high sodium intake and obesity may act synergistically to accelerate cellular aging, according to study leader Haidong Zhu, M.D., Ph.D., assistant professor of pediatrics at Medical College of Georgia. The solution: cutting back on salty foods may help and may be an easier first step toward health for overweight teens than losing weight, Zhu said. High sodium intake among the teens in the study averaged 4,142 milligrams per day; low-intake averaged 2,388 mg per day. The American Heart Association recommends limiting sodium intake to 1,500 mg per day.

Why Peaches and Watermelon Could Be Really Good for You

Who doesn’t love a juicy fresh peach or a chilled slice of watermelon? New research suggests that both may benefit health in important ways. In a study with mice, polyphenols from peach extract proved to slow the growth and spread of breast cancer. Researchers at Texas A&M AgriLife Research gave the peach extract to mice that had been implanted with breast cancer cells. After 12 days the researchers observed less tumor growth than in control animals. In addition, there was also a paucity of the blood vessel formation that helps cancer spread and less evidence of enzymes involved in cancer spread in the mice fed high levels of the polyphenols. The investigators suggested that eating two to three peaches daily might help to slow or stop breast cancer spread in humans and might even help prevent the disease. As for watermelon, a 12-week study with 13 obese adults with high blood pressure demonstrated that a daily dose of four grams of the amino acid L-citrulline and two grams of L-arginine, both from watermelon extract, led to significantly improved blood pressure when the study subjects were under stress, as well as lowering the participants baseline blood pressures at rest.

Optimism Wins Again

Optimistic women have better luck adopting healthy eating habits than women with a more negative outlook on life. But optimism itself isn’t what makes the difference, according to a new study from the University of Arizona, Tucson. Instead, researchers found that the behavioral skills that tend to accompany optimism led to success. These skills include being aware of your own behavior as it is unfolding, monitoring your eating habits by making a mental note of what you’ve eaten or keeping track of your food intake in a journal, and finding a healthy way to cope with unpleasant emotions or stress (instead of smoking or reaching for junk food). For the study, the researchers analyzed information from 33,500 women between the ages of 50 and 79. Among the data gathered were responses to a questionnaire that evaluated optimism levels and a survey of the healthfulness of the participants' diets when the study began and a year later. Overall, the researchers found that the most optimistic one-third of the women improved their diets the most.

My take? We know that optimism can benefit health by positively influencing the immune system, lowering production of the stress hormone cortisol and even reducing the risk of chronic disease. Rather than this trait simply being self-fulfilling, however, I believe optimism can be learned. The trick is remaining mindful enough to identify habitual thoughts and images that make you feel sad or anxious, and substituting positive ideas for negative ones, as well as spending more time with the optimists among your friends and family.

Are Grapes Good For Your Heart?

Want to promote heart health? Look to the grapevine!

Whether you eat the fruit, seeds or skin; drink the juice; or sip on red wine, grapes can help reduce the risk of heart disease. These bright fruits are rich in polyphenols (naturally occurring plant compounds known to have antioxidant activity and other health benefits) including resveratrol, phenolic acids, anthocyanins, and flavonoids, which help to:

  1. Slow or prevent cell damage caused by oxidation, which is an important step in deterring the development of atherosclerosis.
  2. Reduce blood clotting and abnormal heart rhythms.
  3. Lower blood pressure in patients with hypertension.

Choose the darker colored varieties of grapes for the most polyphenol benefits and opt for eating the fruit or skins over juice when able.

How Lifestyle Can Affect Your Vision

Being physically active and having an occasional alcoholic drink both seem to reduce the risk of developing vision problems as you age. Researchers from the University of Wisconsin noted that visual impairment in the U.S. population is projected to increase by 70 percent between the year 2000 and 2020. They attributed most of these projected changes to the expansion of the aging population and the prevalence of age-related eye diseases. The investigators looked at the relationships between the incidence of visual impairment and smoking, drinking alcohol and staying physically active in an ongoing study of nearly 5000 adults aged 43 to 84. They found that only two percent of physically active participants developed visual impairments compared to 6.7 percent of those who were sedentary. After adjusting for age, the researchers found that physically active study participants had a 58 percent reduced risk of developing eye problems. And here’s a surprise: only 4.8 of study participants who drank alcohol occasionally (defined as having consumed alcohol in the previous year, but averaging less than one drink a week) developed visual impairment compared to 11 percent of non-drinkers. Heavy drinkers and smokers also had a higher risk of vision impairment than study participants who never drank heavily and never smoked, but the association was not statistically significant.
