Comparisons between meat and plant-based diets are hotly debated both in the research community and
When it comes to more extremeeating patterns, paleo and keto diets are on one side of the field, and veganism is on the other. Paleo dieters focus on meats, vegetables, fruits and nuts while avoiding beans and grains, while keto practitioners cut out almost all carbohydrates, instead focusing on meats and grains. fats Vegans avoid all animal products, including by-products. Keto diet is one of the most popular at the moment. Global interest in the ketogenic diet is expected to continue to grow, with the market reaching more than $15 billion by 2027. The Paleo diet, another low-carb diet, is gaining popularity.
Researchers from Tulane Universitytook an unusual approach to compare meal plans: They tracked the carbon footprint of paleo and keto diets versus plant-based diets. Carbon dioxide is a key factor in global warming.
To summarize the results, the scientists usedinformation from the dataField database. It tracks the carbon footprint of various foods. The researchers also examined the nutritional effects of different types of diets by applying scores from the federal Healthy Eating Index to data from more than 16,000 adults who participated in the Centers for Disease Control's National Health and Nutrition Examination Survey.
They found that for every 1,000 consumedcalories from the keto diet account for almost 3 kg of carbon dioxide, while the calories from the paleo diet account for 2.6 kg of greenhouse gases. The carbon footprint of a vegan diet is significantly lower - only 0.7 kg of carbon dioxide for every 1,000 calories consumed. This means that paleo and keto diets create almost four times more greenhouse gas emissions than vegan diets.
