explain IN DEPTH HOW AND WHY each line of support promotes longevity.

here is my first draft

“While debates have raged about the role of diet in facilitating longevity and healthy, evidence from theoretical and empirical studies support the fact the diet indeed plays an instrumental role in enhancing longevity and decelerating the process of aging. For example, in a cohort study examining the relationship between diet and longevity, the researcher found out that diet quality and the Mediterranean diet had potential effects on longevity, with the important effects of nutrition on longevity relating with quality, quantity, variety, frequency, and emotional satisfaction [1]. Another study affirmed that dietary restrictions in fatty foods, high cholesterol foods, and reductions in salt intake modulate the genetic pathways that play a direct role in regulating metabolism and aging [2]. In jurisdictions with a reputation of longevity such as Okinawa in Japan and Guiyang province in China, there is high consumption of soybeans as in tofu and other soy products as well as fish that contains taurine, docosahexaenoic acid (DHA), and amino acids, all of which have a positive effect against lifestyle-related disease [3]. Cases of obesity, stroke, and myocardial infarction are less common in these areas because of the consumption of such diets on a daily basis.
Some controversy exists surrounding the factors in exercise that promote longevity and health, but recent advances in the study of the correlation between exercise and longevity have helped to shed light on the factors in exercise that promote longevity and promote healthy aging. A comprehensive literature review relying on 13 evidence-based articles established that sustained physical activity promotes health and longevity via reducing major mortality risk factors including type II diabetes mellitus, coronary heart disease, arterial hypertension, cancer and stroke by 30-35% in physically active individuals [4]. Taking on a longitudinal approach in examining the relationship between longevity and frequency of moderate physical activity, another study found out that increased moderate physical activity increased longevity through reducing cardiac morbidity and improving cognitive functioning as well as the overall quality of life [5]. From a different dimension, researchers investigating the benefits of regular exercise on longevity established that exercises geared towards improving muscle fitness and cardiorespiratory fitness as well as balance and flexibility can preserve functional reserve in the elderly while simultaneously reversing the effects of the aging process on physiological functions [6].
Even though much evidence has amassed on the strong causal relationship between social support and longevity and health, important gaps exist in people’s understanding of the mechanisms of these associations. Drawing from data grounded on longitudinal studies in the United States, one inquiry revealed the a higher degree of social support and social integration improved biomarkers of physical health including BMI, blood pressure, and C-reactive protein in different stages of life, thereby improving health and longevity of citizens with high levels of social support [7]. Similarly, a systematic review conducted on the topic of social support and longevity established that social support improves physical activity in older adults, particularly leisure time physical activity when the support comes from family members, which consequently improves health and longevity [8]. Evidence from a cross sectional study looking at the influence of social support among older Canadians and Latin Americas similarly found out that high levels of social support from family members, partner, children and friends led to low levels of depression and increased the overall quality of life for the participants, leading to better health and higher longevity [9].

This week, you will write the second draft of the Introduction of your paper.  The second draft should include an additional 3  journal articles for EACH paragraph. The first draft had 3 in each paragraph. With 3 added for EACH paragraph, there should be a total of 6  journal articles that provide evidence and support for each topic sentence in EACH of your three paragraphs. The second draft should also explain IN DEPTH HOW AND WHY each line of support promotes longevity. The second draft should be clear and organized and read as a coherent story. Please end the third paragraph with the following sentence (your hypothesis) : The researchers in the present study hypothesize that the impact of lifestyle change will cause an increase in longevity such that higher levels of impact of lifestyle change will cause higher longevity and thus longer life.

In the second draft, make sure to number your  sources as you write and write a list of your sources labelled with the numbers just like you did for the first draft for yourself. Also, make sure there are clear transitions between paragraphs and a few sentences at the very beginning of the first paragraph addressing health and longevity globally before the topic sentence of the first paragraph begins.
