As a runner, you have two jobs. One is to eat wisely to run well. The other is to stay healthy. That includes sleeping well, eating well, and living well. Wellness was the theme of the 35th Annual Symposium for the more than 7,000 sports dietitians who are members of SCAN, the Sports and Cardiovascular Nutrition dietary practice group (SCANdpg.org) of the Academy of Nutrition and Dietetics. Here are some highlights that offer food for thought and tips for health:
• Health claims made about coconut oil are misleading. They were created by marketing gurus using research based on medium chain triglyceride (MCT) oil, not coconut oil. Coconut oil does contain MCTs, but primarily lauric acid, a MCT that behaves like a long chain saturated fat in terms of digestion and metabolism. Lauric acid raises bad (LDL) cholesterol, inflammation, coagulation and insulin resistance (1).
One tablespoon of coconut oil has 13.5 grams saturated fat. Given the American Heart Association recommends limiting saturated fat intake to less than 7% of total calories, that’s only 15.5 grams a day per 2,000 calories. Runners with high LDL would be wise to use coconut oil only sparingly.
• Does drinking 1 to 2 glasses of wine a day offer positive health benefits? Perhaps not, given there are 25 alcohol-related diseases, to say nothing of links between alcohol and certain cancers, CVD, intestinal issues, injuries from accidents, and suicide. Unless you are among the estimated 35% of Americans who abstain from alcohol, the least harmful way to drink is to limit alcohol to one to two drinks only three to four times a week (not daily). And be sure that one drink is actually just one standard drink (6 oz wine, 12 oz beer, 1.5 oz spirits)—and not the “bartender’s special.”
• Lutein (in egg yolk, spinach, avocado, dark green, and yellow and orange foods) is important for eye health; it curbs age-related macular degeneration. Lutein is also good for your brain and is associated with a reduced risk for dementia. Adults with normal brain function have three times more lutein in their brain than those with cognitive impairment. Enjoy lots of colorful fruits and veggies to consume the recommended lutein intake.
• Knowledge is necessary, but not sufficient, for runners to make sustained lifestyle changes that improve their health. We change our behaviors based on our values. For example, vegetarians generally express concern about the environment and animal welfare. In light of environmental concerns, seems like we need public health campaigns that focus on values, so that more people will eat less meat, waste less food, and choose fewer snacks in single-serve plastic containers.
• Runners can easily lose sleep by going to bed too late, drinking too much coffee, having sleep apnea, and needing to urinate during the night. Sleep loss is associated with accidents, metabolic disorders, weight gain, and hunger (due to increases in the hunger-hormone grehlin). Exercise does not protect against the harmful effects of sleep deprivation. Routinely dragging yourself out of bed in the morning to run might not be a wise plan. Seven hours of sleep a night are recommended to avoid sleep deprivation.(08/11/2019) ⚡AMP
