Despite substantial possible biological and atomic evidence contrary to the evidence that certain vitamins prevent heart disease. The theoretical preventative effects of completely diets and particular food habits cardiovascular disease have been brought to light by using Nutritional Methods for Heart Disease (DASH) initiative. To ensure a precise evaluation of the correlation between diet and illness, these patterns were assessed in adherence to the latest prevention guidelines for heart disease. Adherence to the "Healthy", "Prudent", "The Mediterranean", and "dash compliant" diets has demonstrated to substantially reduce the incidence of cardiovascular disease by 10-60%, according to extensive observational research. Nevertheless, the statement is devoid of precision due to the omission of the specific research to produce the aforementioned outcomes. While this research seems to lend support to whole-diet approaches for disease prevention, the categorization of dietary scores is based on a limited or erroneous understanding of the correlation between diet and illness. Given the scarcity of high-caliber intervention studies that utilize whole cuisines and condition aims as the primary result, this is particularly concerning. In addition to critiquing diets that are based exclusively on data concerning particular nutrients, this review emphasizes in the notion that general dietary practices reduce the possibility of heart disease. It advocates not only for the adoption of comprehensive dietary and food-based approaches for avoiding heart disease, but also for the enforcement of stricter regulations in this regard, controlled trials.
