This advice is particularly robust and aligns perfectly with current scientific data on general vitality. Regarding fiber, a meta-analysis of observational studies conducted by Reynolds et al. (The Lancet) demonstrates that a daily intake of 25 g or more is ideally linked to better cardiovascular well-being. Furthermore, a meta-analysis of randomized controlled trials (RCTs) published by So et al. in the American Journal of Clinical Nutrition confirms that such fiber intake positively shapes the microbiota by promoting the activity of beneficial bacteria. Concerning plant intake, the target of 500 to 600 g per day also proves to be highly relevant. A large meta-analysis of prospective observational studies conducted by Aune et al. (International Journal of Epidemiology) indicates that protective benefits for general health continue to optimize between 500 g and 800 g per day. Although the classic minimum threshold of official recommendations is often set at 400 g per day, aiming for the higher range proposed by the creator helps maximize micronutrient and water intake without any exaggeration.
