What is a flexitarian diet? How does it work

A flexitarian diet, also known as a semi-vegetarian diet, emphasizes plant foods with limited or occasional meat consumption. As per a new study, published in the journal BMC Nutrition, a flexitarian diet was linked with lower cardiovascular risk than an omnivorous diet.

The study underlines the benefits of eating more plant-based foods instead of meat for better cardiovascular health.

A total of 94 participants were studied
The study aimed to investigate the effects of a flexitarian diet on heart health. It involved 94 participants between the ages of 25 and 45 who had been following a vegan, omnivorous, or flexitarian diet for at least a year prior to the study. Individuals who consumed less than 50 grams of meat per day were classified as flexitarians, while those who consumed 170 grams or more of meat were categorised as omnivores. Vegans, who completely avoided animal products, constituted the third group.


To assess the participants' dietary habits and lifestyle factors, questionnaires were used.

Outcomes of the study
On the day of the study, blood samples were collected from the participants to evaluate cardiovascular disease biomarkers. Additionally, the researchers measured the participants' blood pressure, body mass index, and arterial stiffness during the visit. The blood biomarker analysis revealed that both flexitarians and vegans had better cardiovascular health than omnivores. Specifically, they exhibited lower levels of total cholesterol and low-density lipoprotein (LDL) cholesterol than omnivores.

Furthermore, compared to omnivores and flexitarians, vegans showed lower fasting insulin levels, although the difference lost significance when the researchers adjusted for cofounders. Lastly, flexitarians and vegans had lower metabolic syndrome severity scores, which is a composite measure of various cardiovascular risk factors, including blood glucose levels, blood pressure, cholesterol levels, and weight.

What does a flexitarian diet include?

A flexitarian diet primarily consists of plant-based foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. Flexitarians occasionally incorporate animal products like meat, poultry, fish, dairy, and eggs into their meals but in smaller quantities and less frequently than traditional omnivores. The emphasis is on plant-based eating for health and environmental benefits, with flexibility to include animal products based on personal preference or occasional cravings. This approach encourages a diverse and nutrient-rich diet while reducing overall meat consumption, making it suitable for those seeking a more sustainable and balanced way of eating.

Benefits of a flexitarian diet

The flexitarian diet offers numerous health benefits by emphasizing plant-based foods while allowing occasional consumption of animal products. It promotes weight management due to its focus on nutrient-dense, lower-calorie plant foods and reduced intake of high-calorie meats. Flexitarians typically have lower risks of chronic diseases such as heart disease, diabetes, and certain cancers due to higher intake of fiber, antioxidants, and phytonutrients. Additionally, the diet supports digestive health, boosts energy levels, and improves overall well-being. From an environmental standpoint, reducing meat consumption lowers greenhouse gas emissions and reduces water usage, making the flexitarian diet a sustainable choice for both personal health and the planet.
