Research Study 2025

Intermittent Fasting & Metabolic Health

Recent meta-analysis of 27 randomized controlled trials reveals significant improvements in insulin sensitivity, blood lipid profiles, and inflammatory markers with time-restricted eating patterns. The study, published in Nature Metabolism, demonstrates that 16:8 intermittent fasting protocols can enhance metabolic flexibility without compromising muscle mass.

Systematic Review 2025

Plant-Based Diets & Cardiovascular Health

Comprehensive review of 45 prospective cohort studies involving over 2.3 million participants shows strong association between plant-based dietary patterns and reduced risk of cardiovascular disease. The research, featured in the Journal of the American Heart Association, highlights the protective effects of whole grains, legumes, and nuts.

Published: November 2025
Clinical Trial 2025

Omega-3 Fatty Acids & Cognitive Function

Randomized double-blind placebo-controlled trial with 1,200 participants aged 65+ demonstrates that daily supplementation with EPA and DHA omega-3 fatty acids significantly improves cognitive performance and reduces age-related cognitive decline. Findings published in Neurology suggest optimal benefits at doses of 1,000-2,000 mg daily.

Meta-Analysis 2025

Gut Microbiome & Immune Function

Analysis of 38 studies reveals strong correlation between gut microbiome diversity and immune system resilience. Research published in Cell Host & Microbe demonstrates that dietary fiber intake directly influences beneficial bacterial populations, which in turn modulate immune responses and reduce inflammation markers.

Evidence-Based Nutrition Pyramid

1

Foundation: Whole Foods

Base your diet on minimally processed whole foods including vegetables, fruits, whole grains, legumes, nuts, and seeds. These provide essential nutrients, fiber, and phytochemicals.

2

Macronutrient Balance

Maintain appropriate ratios of carbohydrates (45-65%), proteins (10-35%), and fats (20-35%) based on individual needs, activity level, and health goals.

3

Micronutrient Adequacy

Ensure sufficient intake of vitamins and minerals through diverse food choices. Focus on nutrient-dense foods to meet daily requirements without supplementation when possible.

4

Timing & Frequency

Consider meal timing, eating frequency, and circadian rhythms. Research suggests aligning eating patterns with natural biological rhythms may optimize metabolic health.

5

Personalization & Adaptation

Tailor dietary patterns to individual genetics, metabolism, health status, preferences, and lifestyle. Monitor and adjust based on health markers and outcomes.
