Document Summary
In 1960, 13% of us adults were obese. Today, 69% of us adults are overweight/obese. Health risks of obesity classified using three indicators: bmi, waist circumference, disease risk profile. How to measure body fat percentage: dexa, skinfold test (callipers) High obesity rates are a problem because of obesity associations with other health conditions. Multiple mechanisms: connection between chronic disease, inflammation, and fat: adipokines (hormones released by fat cells) Central obesity: visceral fat vs. subcutaneous fat. Us: 83 million men and women suffer from cvd. Atherosclerosis: hardening of the arteries, begins with soft fatty streaks along inner artery walls, gradually enlarge and become hard, fibrous plaques that damage and narrow artery walls. Decreasing your risk: lower saturated and trans fat intake, intake of omega 3"s, maintain appropriate weight and blood pressure, physical activity, avoid smoking and alcohol. Nutrition and cancer: energy intake, physical activity, alcohol, red meat and meats at high temperature, fiber, phytochemicals.
