Adequacy of Essential Fatty Acids in a Vegan Diet
Omega-3 fatty acids (EPA and DHA) are important nutrients especially for brain health and protection against depression, dementia and neurologic disorders. This study tested fatty acid levels in vegan subjects of various ages. Results showed that 64 percent had insufficiencies and that 27 percent had more severe deficiencies. These deficiencies were easily corrected with a low-dose vegan DHA/EPA supplement. This study concluded that due to a wide genetic variability in conversion of ALA to DHA un-supplemented vegans might place themselves at needless risk.
Nutritarian Lifestyle Intervention Study
This brief lifestyle intervention study, which included a nutritarian diet rich in fresh fruits and vegetables, whole grains and various legumes, nuts and seeds, significantly improved health risk factors and reduced systemic inflammation as measured by circulating CRP.The degree of improvement was associated with baseline CRP such that higher levels predicted greater decreases. The interaction between gender and baseline CRP was significant and showed that males with higher baseline CRP levels appeared to have a more robust decrease in CRP due to the intervention than did their female counterparts.
It is likely that the vegetable and high fiber content of a nutritarian diet reduces CRP in the presences of obesity. Neither the quantity of exercise nor the length of stay was significant predictors of CRP reduction. Additionally, those participants who had a vegan diet prior to the intervention had the lowest CRP risk coming into the program. Direct measure of body fat composition, estrogen and other inflammatory mediators such as IL-6 and TNF-alpha would enhance current understanding of the specific mechanisms of CRP reduction related to lifestyle interventions.
Improved Cardiovascular Parameter with a Nutrient-Dense, Plant-Rich Diet-Style:
A Patient Survey with Illustrative Cases
Newly published article describing research spearheaded by Dr. Fuhrman in the American Journal of Lifestyle Medicine.
Cardiovascular disease is the leading cause of death in the United States, accounting for approximately one-third of deaths. Heart disease takes a huge toll on the health of our society and our economy. The evidence suggests that cardiovascular disease is driven in a large part by lifestyle factors, such as low vegetable and fruit consumption, high glycemic load diets, obesity, and a sedentary lifestyle. This survey study documented the dramatic effects a nutritarian diet has on lowering blood pressure and reversing heart disease. In over 450 people systolic blood pressure dropped 26 ml/Hg, within 6 months. That represents more lowering in blood pressure than any other nutritional intervention and even more than most blood pressure medications.
This study also showed powerful case studies of individuals who reversed severe atherosclerotic heart disease making complete recoveries.
