Scientists agree that having a gut microbiota that is in ‘good shape’ is a crucial component of individual health and well-being. Although exactly how ‘good shape’ is defined is not so clear, many experts recommend consuming more live dietary microbes through including fermented foods that retain live microbial components.

Numerous studies have been published on the impact of factors such as nutrition in early life, mode of delivery and antibiotic intake during this critical period and for future health. With that in mind, scientists have reviewed all the scientific data available on the impact of early life nutrition on the gut microbiota and the long-lasting effects on the brain.

Food, and its food components, nutrients or additives, can affect the composition and function of the gut microbiota. This article provides a summary of the food components that contribute to optimal microbiota health and explains how they can impact it.

Following a diverse diet, rich in fruits, vegetables, whole grains and fermented foods, could play a protective role against severe forms of COVID-19. A new review presents the hypothesis highlighting the link between a less diversified microbiota, a high intake of processed foods and refined sugars and severe Covid-19 cases in Western countries.
