Vegan diet

The vegan diet is a strictly plant-based dietary pattern that completely excludes all animal-derived ingredients, including meat, poultry, fish, dairy, eggs, and honey. Instead, it relies entirely on plant foods such as vegetables, fruits, whole grains, legumes, nuts, and seeds. When properly planned, a vegan diet is highly nutrient-dense, providing an abundance of dietary fiber, vitamins, minerals, and phytonutrients while being naturally low in saturated fats and dietary cholesterol.

A vegan diet works by shifting macronutrient and micronutrient intake toward plant-based sources. Replacing animal products with plant foods significantly increases the intake of dietary fiber, antioxidants, and phytochemicals. This combination slows glucose absorption, stabilizes blood sugar, and promotes satiety. Physiologically, the absence of animal fats and the high fiber content lower low-density lipoprotein (LDL) cholesterol, improve insulin sensitivity, and reduce systemic inflammation. Beneficial shifts in the gut microbiome and reductions in pro-atherogenic compounds, such as trimethylamine N-oxide (TMAO), also contribute to its broad cardiovascular and metabolic benefits.

• Supplement Essential Nutrients: It is strictly recommended to supplement Vitamin B12, as it is absent in plant foods. Also, consider supplementing Vitamin D3, algal Omega-3 (EPA/DHA), calcium, iodine, and zinc to prevent critical nutritional deficiencies. • Prioritize Whole Foods: Emphasize minimally processed, whole-plant foods (legumes, whole grains, vegetables, and nuts) over highly processed vegan meat and dairy alternatives, which can negate health benefits. • Monitor Bone Health: Studies suggest a vegan diet may be associated with an increased risk of bone fractures. Ensure adequate calcium and Vitamin D intake, and engage in weight-bearing exercises to support bone mineral density. • Preserve Muscle Mass: Recent research indicates that while vegan diets improve body composition and reduce fat, they can lead to muscle mass loss without proper countermeasures. Consume diverse protein sources (e.g., soy, lentils, quinoa) and engage in regular resistance training. • Focus on Iron Absorption: Since non-heme iron from plants is less bioavailable, pair iron-rich foods with Vitamin C sources to enhance absorption, protecting against anemia.
