How does intake of common salt cause heart disease?
S.SangeethaChennai ANSWER: Intake of common salt is primarily related to the development of hypertension 9HT, which is a major risk factor for the development of heart attack called Coronary Heart Disease(CHD). For many diseases, the disease agent is still unidentified, e.g., CHD, cancer, peptic ulcer, mental illness, etc. In these conditions, the cause of the disease is generally discussed in terms of risk factors. Risk factors are often suggestive, but absolute proof of cause and effect between a risk factor and disease is usually lacking. The effect of risk factors is multiplicative rather than additive; thus, people with combination of risk factors (e.g., smoking, HT, diabetes etc.,) have the greater risk of developing CHD. It is important to distinguish between relative risk (the proportional increase in risk) and the absolute risk (the actual chance of an event). Thus, a person of 35 with high cholesterol level who smokes 40 cigarettes a day is relatively much more likely to die
