Regular Exercise and Fish Oil May Keep Arteries Clear and Reduce Body Fat
At a Glance: Fish oil supplements and regular exercise both reduce body fat and improve cardiovascular and metabolic health. Read more about this research below. A combination of prolonged exercise and fish oil can dramatically reduce levels of a fat that can cause hardening of the arteries, a leading cause of heart disease. Fat in the bloodstream is a primary contributor to atherosclerosis, or partial blockage of the arteries. A recent study found that people who do prolonged aerobic exercise have muscle cells that are able to quickly break down and reduce levels of a fat called triglycerides. Taking a fish oil supplement can reduce triglyceride levels even more. The researchers studied triglyceride levels in recreationally active men after they'd eaten high-fat meals. One group ate a fatty meal after they exercised. A second group ate a high-fat meal after taking a four-gram fish oil supplement. A third group ate a high-fat meal after exercising and taking the fish oil supplement. A control group ate a high-fat meal only. The study found a 38 percent decline in peak triglyceride levels in the men who took a fish oil supplement before they ate a high-fat meal. Peak triglyceride levels dropped 50 percent in the men who exercised and took a fish oil supplement before they ate a high-fat meal. Regular exercise and fish oil supplements may be beneficial for people who are concerned about maintaining a healthy triglyceride level. Metabolism. 2004 Oct;53(10):1365-71. In a similar, more recent study, combining fish-oil supplements with regular exercise improved both body composition and heart disease risk factors. Overweight participants with various heart disease risk factors were assigned to one of three groups: fish oil (approximately 1.9 grams/day of omega-3 fats), fish oil and exercise, or placebo (sunflower oil). The exercise group walked 3 days/week for 45 minutes. Heart disease risk factors and body composition were measured at 0, 6, and 12 weeks. The group taking fish oil had a significant reduction in triglycerides, increased HDL cholesterol, and improved arterial vasodilation (blood flow). Both fish oil and exercise independently reduced body fat. This study showed that increasing intake of omega-3 fatty acids could be a useful addition to exercise programs aimed at improving body composition and decreasing cardiovascular disease risk.

PICKING HEALTHY RESTAURANT FOODS NOT SO EASY
Nisan 18, 2007
Poll finds most people can’t identify best choices at chain eateries
Picking the healthiest item on a restaurant menu is not as easy as it seems, according to a new poll that found most respondents were unable to identify the dishes lowest in calories, salt and fat.
In the poll, which was commissioned by the California Center for Public Health Advocacy, 523 respondents were given a choice of four menu items from popular restaurant chains and asked to select which were lowest in fat, calories and salt.
The first question asked people to choose which Denny’s dish was lowest in calories: a ham and cheddar omelet, country fried steak and eggs, three slices of French toast with syrup and margarine, or three pancakes with syrup and margarine.
The answer? Country fried steak and eggs.
The poll’s other three questions asked respondents to make similar choices about menu items from Chili’s and Macaroni Grill, both units of Dallas-based Brinker International Inc., and from No. 1 restaurant chain McDonald’s.
None of the respondents answered all four questions correctly, and 68 percent failed all of them. Less than 1 percent answered three of four questions correctly, and education and income levels had no impact, the CCPHA said.
The CCPHA said the poll’s results contrast with the restaurant industry’s claims that eateries “offer plenty of healthy choices and people just need to order better.”
“I have a doctorate in public health, and I failed this quiz,” Dr. Harold Goldstein, executive director of the CCPHA, said. “Common sense does not help … who would think that a large chocolate shake at McDonald’s has more calories than two Big Macs?”
In recent years, many chains, including Denny’s and McDonald’s, have voluntarily posted the nutritional information of their foods online or in their restaurants.
Those moves came as restaurant chains faced increasing criticism from health advocates and others for contributing to the prevalence of obesity among U.S. adults and children.
