A new dietary review of 49 observational and controlled studies finds plant-based vegetarian diets, विशेष रूप से शाकाहारी आहार, कुल कोलेस्ट्रॉल के निचले स्तर के साथ जुड़े रहे हैं, including lower levels of HDL and LDL cholesterol, compared to omnivorous diets.
The meta-analysis appears as an online advance in Nutrition Reviews.
The study authors — Yoko Yokoyama, पीएच. डी., मील प्रति घंटे, Susan Levin, M.S., आर.डी., C.S.S.D., and Neal Barnard, एम. डी., F.A.C.C. — reviewed 30 observational studies and 19 क्लिनिकल परीक्षण, which met their inclusion criteria. They find:
A plant-based vegetarian diet is associated with total cholesterol that’s 29.2 mg/dL lower in observational studies.
नैदानिक परीक्षणों में, a plant-based diet lowers total cholesterol by 12.5 मिग्रा /.
In observational studies, a plant-based vegetarian diet is associated with a 22.9 mg/dL reduction in LDL cholesterol and a 3.6 mg/dL reduction in HDL cholesterol, compared to control groups following an omnivorous diet.
नैदानिक परीक्षणों में, a plant-based vegetarian diet lowers LDL cholesterol by 12.2 mg/dL and reduces HDL cholesterol by 3.4 मिग्रा /, compared to control groups following an omnivorous, low-fat, calorie-restricted, or a conventional diabetes diet.
A plant-based vegetarian diet is not associated with statistically significant changes in triglyceride levels in observational studies or in clinical trials.
The authors predict the strong correlation between vegetarian diets and lower cholesterol levels may be due to the association a plant-based diet has with a lower body weight, a reduced intake of saturated fat, and an increased intake of plant foods, like vegetables, फल, फलियां, पागल, and whole grains, which are naturally rich in components such as soluble fiber, soy protein, and plant sterols.
The study authors hypothesize that the greater risk reduction for total, एचडीएल, and LDL cholesterol levels observed in the longitudinal studies is likely due to long-term adherence to plant-based eating patterns and changes in body composition.
“The immediate health benefits of a plant-based diet, like weight loss, कम रक्त दबाव, and improved cholesterol, are well documented in controlled studies,” says study author Susan Levin, M.S., आर.डी., C.S.S.D. “Our goal with studying plasma lipids throughout the lifespan is to capture the net risk reduction of using a vegetarian diet to control lipid levels. We hope to empower patients with new research about the long-term cardiovascular health benefits of a vegetarian diet, which include a reduced risk of a heart attack, स्ट्रोक, and premature death.”
Charles Ross, डी. ओ., a member of the nonprofit Physicians Committee and a former emergency department physician, has firsthand experience with putting a plant-based diet into practice.
डॉ.. Ross is in his late 60s, takes no medications, and lowered his previously high total cholesterol from 230 mg/dL to a healthy 135 mg/dL after adopting a whole-food, plant-based diet in 2012. Within the first month of making the dietary change, he effortlessly lost 10 पाउंड. Within a year, डॉ.. Ross traded a 34-year career of practicing emergency medicine for a new career path: lifestyle medicine. के बाद 5.5 years of making the career switch, he continues to host free biweekly nutrition classes for his primary care patients and the community. से अधिक 700 people have enrolled to learn how to lose weight, eliminate the need for medications to treat type 2 मधुमेह, उच्च रक्तचाप, and elevated cholesterol, and to simply feel better. His former hometown of Roseburg, अयस्क।, is now a Blue Zones community. He is a part-time instructor at the College of Osteopathic Medicine of the Pacific Northwest and hopes to set an example for future physicians.
“I no longer work for a living,” नोट्स डॉ.. Ross, who now resides in Westfir, अयस्क. “I wake up every day eager to hear about how a plant-based diet and a healthful lifestyle is changing and saving lives in our community. What I’ve found is that if you want your patients to make significant health changes, you have to make them yourself. The prescription started to spread soon after my family, co-workers, neighbors, and friends heard about my experience.”
For clinicians concerned about spending extra time in and outside of the exam room, the study authors encourage time-strapped health care providers to refer patients to registered dietitians who can help with the transition to a plant-based vegetarian diet. को 2015 Dietary Guidelines for Americans highlights a healthy vegetarian diet as one of three healthful eating plans to follow.
The study authors also note hyperlipidemia, or elevated cholesterol and triglycerides, is often underdiagnosed and undertreated. A 10 percent increase in the prevalence of treatment for hyperlipidemia can prevent 8,000 deaths each year. Taking small steps, like those proposed by the National Cholesterol Education Program Adult Treatment Panel 3, which include assessing heart disease risk, making lifestyle and dietary recommendations, and assessing the need for future follow-up appointments and pharmaceutical interventions, could prevent approximately 20,000 दिल के दौरे, 10,000 cases of coronary heart disease, and save almost $3 billion in medical costs each year.
“To make any form of health care work and to truly power economic mobility, we have to get healthy,” says Levin. “The first place to start is by building meals around nutrient-packed, plant-based foods, which fit into nearly every cultural template, taste preference, and budget.”
