Modern diets have halved human gut microbial mass
  • In the 1950s, an average adult harbored about 21 kg of gut microbes; today that number has dropped to roughly 11 kg, a loss of nearly 50 %.
  • Dr. Vali attributes this decline to low‑fiber, high‑sugar diets that starve beneficial bacteria.
  • The reduction correlates with rising autoimmune and metabolic disorders, as the microbiome loses its regulatory functions.
  • He emphasizes that millet’s soluble and insoluble fibers act as pre‑biotics, feeding the remaining microbes and encouraging regrowth.
  • Restoring fiber intake to 30‑40 g per day, primarily from millets, can reverse the microbial loss within months.

Gut Microbiome: Fiber's Hidden Power

A core theme is how millet's high fiber content fuels a diverse gut microbiome, which in turn protects against a host of chronic diseases. Dr. Vali provides quantitative data on microbial mass loss over the past decades.
