Diet And Gut Microbiota

The human body hosts more microbes than body cells. All human-associated microbes are collectively known as microbiota and the microbiota encoding genes form the microbiome. Gut microbiota also called gut flora is the name given to the microbe population living in our intestine. Our gut microbiota contains tens of trillions of microorganisms, including at least 1000 different species of known bacteria with more than 3 million genes. In fact, it contains ten times more cells than the human body and 150 times more genes than the human genome.

One-third of our gut microbiota is common to most people, while two-thirds are specific to each one of us. In other words, the microbiota in our intestine is like an individual identity card. Although more than 1,000 different known bacterial species can be found in human gut microbiota, only 150 to 170 predominate in any given subject.

About 50% of the fecal mass is made up of bacteria. This population is composed of trillions of microorganisms that belong to 4 main groups: Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria, with 90% predominance of the first two. Each one of us has a unique microbiota but it always fulfills the same physiological functions with direct impact on our health.

Healthy Food - An Attempt to Meet Diners' Desire

Sustainable Development Goal 3 (SDG 3), one of the 17 Sustainable Development Goals established by the United Nations in 2015, was about "Good Health and Well-being". This could be said to be an eye-opener and the source of making people aware of maintaining their health, which became more pronounced due to the Covid-19 pandemic. Consuming healthy food, since then, has become a significant - if not imperative - element in lives of almost everyone. And this healthy and nutritious food is also playing a significant role in the success of restaurants. Diners are now becoming more particular about the food they consume, making the F&B outlets offer a diverse and appealing menu of healthy food options. Ashok Malkani tries to evaluate how the restaurants and chefs are meeting this desire for nutritious food by customers and what are some of the healthy food options.
