Identical twins ate two different healthy diets and vegan clearly won in study
Evidence shows that a vegan diet presents potential cardiovascular benefits from improved diet quality, so a clinical trial studied identical twins who ate two different healthy diets – and the findings showed a clear winner.
Facts and figures about food have always been popular, with studies showing how cutting down processed meat in your diet can reduce major health risks, or how maintaining a Mediterranean diet can reduce acne. An investigation into the cardiometabolic effects of omnivorous compared to vegan diets has been researched in identical twins and the results will help clinicians in the future.

Investigation into identical twins eating two different healthy diets
The study published in the JAMA network questioned the cardiometabolic effects of a healthy plant-based, vegan diet compared to a healthy omnivorous diet among identical twins, during an eight-week intervention in 2022.
22 healthy, adult, identical twin pairs were randomized to follow either a healthy vegan diet or a healthy omnivorous diet for eight weeks. Diet-specific meals were provided using a meal delivery service from baseline through week four, and from weeks five to eight participants prepared their own diet-appropriate meals and snacks.
An omnivorous diet�includes both plant and animal foods whereas a vegan diet includes only plant foods such as fruits, vegetables, beans, grains, nuts, and seeds, and doesn’t contain any animal foods, like dairy, eggs, and honey, as per WebMD.
It was undertaken since increasing evidence suggests that a vegan diet confers potential cardiovascular benefits from improved diet quality in comparison to an omnivorous one. Cardiovascular disease is�an umbrella name for conditions that affect your heart or�circulation.
Medical News Today reports that studies have shown�an omnivorous diet rich in meats is associated with an increased risk of cardiovascular disease than plant-based diets.
According to Harvard Medical School, your cardiovascular system includes your heart, blood, and blood vessels. Cardiometabolic health is a term that refers to a combination of many of these risk factors.

Results of the vegan vs omnivorous diet show a clear winner
The objective of the investigation was to compare the effects of the two different diets on cardiometabolic measures.
Those consuming a healthy vegan diet showed significantly improved low-density lipoprotein cholesterol concentration, fasting insulin level, and weight loss compared with twins consuming a healthy omnivorous diet.
The findings suggest that a healthy plant-based diet offers a significant protective cardiometabolic advantage compared with a healthy omnivorous diet. In the trial, the healthy vegan diet led to improved cardiometabolic outcomes compared with a healthy omnivorous diet.
Clinicians can therefore consider this dietary approach as a healthy alternative for their patients.
