Understanding Flexitarianism
A flexitarian diet blends the principles of vegetarian and sometimes vegan diets with a more lenient approach to meat consumption. Unlike a strict vegetarian or vegan diet, a flexitarian—or "flexible vegetarian"—approach emphasizes plant-based foods while allowing meat and other animal products in moderation.
The foundations of a flexitarian diet involve prioritizing:
Vegetables
Fruits
Legumes
Whole grains
These plant-based foods are selected for their lower carbon footprint relative to meat-based foods and for their health benefits. A flexitarian strives to reduce meat intake, mainly because of the significant environmental impact of animal agriculture.
Dietary protein, often sourced from animal products, is instead obtained through alternative means. For flexitarians, common sources of plant-based protein include:
Beans and peas
Lentils
Tofu and tempeh (What wine goes well with tempeh?)
Nuts and seeds
Occasional inclusion of meats or fish should be viewed as an accompaniment, not the centerpiece. This balance is crucial in reducing one's dietary carbon footprint.
Expert dietitians recognize the flexitarian diet as sustainable and potentially beneficial for health. It can lead to a lower body mass index (BMI) and decreased risks of chronic conditions, such as heart disease and Type 2 diabetes, without sacrificing enjoyment and variety in eating.
Promoting the flexitarian diet underscoring the impact on environmental sustainability, especially in reducing greenhouse gas emissions, connects individual dietary choices with global ecological well-being.
