In an eight-week trial, researchers found that a plant-based meat analog diet did not significantly improve cardiometabolic health biomarkers compared to an omnivorous diet in a Singaporean cohort.
By Hugo Francisco de SouzaReviewed by Susha Cheriyedath, M.Sc.Jun 28 2024 In a recent study published in The American Journal of Clinical Nutrition , researchers conducted an eight-week-long randomized controlled trial to evaluate the impacts of consuming a plant-based meat analog diet versus one composed of an omnivorous animal-based one .
Background Despite being naturally omnivorous, religious and cultural edicts have historically resulted in many geographically diverse human communities primarily consuming plant-based diets . This observation is particularly prevalent in Asian and Indian regions, wherein some religious sects require their followers to abstain from meat and meat products.
About the study In the present study, researchers hypothesize that substituting ABDs with PBMDs will gradually improve human cardiovascular health, observable through a postulated reduction in negative cardiometabolic risk markers. They tested their hypothesis in a publicly sourced Singaporean cohort conducted at the Clinical Nutrition Research Centre, Singapore. Sample screening comprised participants' completion of questionnaire-based lifestyle, food frequency, and health histories.
"These included a selection of 6 frozen foods that were broadly categorized as follows: 1) beef mince, 2) pork mince, 3) chicken breast, 4) burger patty, 5) sausage, and 6) chicken nuggets provided via scheduled deliveries to each participant's home. Corresponding to this list, the PBMD group was provided with the following foods: 1) Impossible Beef , 2) OmniMeat Mince , 3) Chickened Out Chunks , 4) Beyond Burger , 5) Beyond Sausage Original Brat , and 6) Little Peckers .
Dietary evaluations revealed that proteins and saturated fats both presented time effects, wherein values postintervention were substantially higher than at baseline. In contrast, carbohydrate intake was observed to reduce. Protein increases were most prominent in the AMBD cohort, while the PBMD cohort displayed more significant reductions in cholesterol, sodium, and potassium. Study intervention compliance was observed to be high overall – 87% in PBMD and 95% in ABMD participants.
