As part of the new study, the researchers looked at 30 randomized trials published between 1982 and 2022, with a total of 2,372 participants. They examined the effects of a vegetarian or vegan diet compared with an omnivorous diet that includes animals and plants on:
-Low-density lipoprotein, also known as LDL or “bad” cholesterol
-Triglycerides; a type of fat or “lipid” found in the blood
-Apolipoprotein B, also known as apoB, a protein that helps carry fat and cholesterol in the blood
This is the first meta-analysis on the topic published since 2017, and the first to look at the effects of continent, age, body mass index and health status, as well as the effect of diet on concentrations of apoB — a harmful fat in the body and a good indicator of total cholesterol.
Benefits of a plant-based diet.
“We found that vegetarian and vegan diets were associated with a 14 percent reduction in all artery-clogging lipoproteins, as shown by apolipoprotein B. This is equivalent to a third of the effect of taking cholesterol-lowering drugs, such as statins, if A person who maintains a plant-based diet for five years also reduces their risk of cardiovascular disease by 7 percent,” Dr. Ruth Frikke-Schmidt, chief physician at Rigshospitalet in Copenhagen, said in a press release.
