exercise are crucial factors. But according to the research finding published by the American Journal of Preventive Medicine, it has been found that calorie intake may not be a major factor in causing death by heart disease.
The finding was based on a 17-year study of almost 9,790 Americans, who participated in the First National Health and Nutrition Examination Survey, a national study which was done from 1971 to 1975. The participants were grouped based on reports of caloric intake (low, middle, high), recreation exercise (least, moderate, most) and body mass index (normal, overweight, obese).
During 17 years of follow-up, 1,531 participants died of heart disease. Adjustment for BMI and physical activity was done and the researches found that caloric intake was unrelated to heart disease, while those who exercised more and ate more were both leaner and had less than half the cardiovascular disease mortality than did those who exercised less, ate less and were overweight. The difference in mortality rates was 55 percent.
The research finding highlights that expending energy through physical activity may be the key to cutting the risks of heart disease and living a longer, more healthful life. Concurrently the outcome of Heart disease was not determined by a single factor, but rather by a compound of behavioral, socioeconomic, genetic and clinical characteristics.
The most practical outcome of the study was for a focus on increased energy expenditure rather than reduced caloric intake as the most productive behavioral strategy by which to extend healthy life.
