What Should You Really Eat? 6 Evidence-Based Food and Nutrition Principles

This article examines six evidence-based principles of food and nutrition, synthesising current nutritional science, microbiome research, and the dietary wisdom of the Indian Ayurvedic tradition. The six principles examined are: the primacy of food quality over macronutrient ratios (whole foods vs processed foods as the most significant dietary distinction); the gut microbiome as the primary mediator of nutritional outcomes (diversity, fibre, fermented foods); the anti-inflammatory dietary pattern (Mediterranean and traditional Indian diets as the best-evidenced long-term health frameworks); the timing of eating and its interaction with circadian biology; the specific nutritional requirements of the Indian population given genetic, cultural, and epidemiological factors; and the Ayurvedic understanding of Agni — digestive fire — as the framework for personalised nutrition based on constitutional type and seasonal variation. Common nutritional myths are identified and corrected with current research evidence.
