As a science insider in nutrition, two things concern to me.

Preservation of the ancestral gut biome
Too much ultra-processed food and not enough healthy food can alter our gut microbiome in a negative way, contributing to chronic inflammation. It’s like "global warming" on the inside, increasing the risk of T2 Diabetes, Fatty Liver, Heart Disease, Stroke and Dementia.

The extinction of key gut bacteria—passed down for generations before industrialization, may have unknown but severe consequences for our future health and resilience.

Epigenetic changes
The food choices we make today don’t just impact us—they shape the health of future generations. Poor nutrition and inactivity alter our genetic expression, and it’s passed onto our children, increasing the likelihood of type 2 diabetes, fatty liver, and accelerated fat storage in them. With each generation, these inherited changes could weaken the human genome, creating a cascade of health risks we can’t afford to ignore.

The stakes are high, but the solutions are within reach. By getting and staying organized around nutrient-dense foods and a lifestyle that supports our genetic and microbial heritage, we can steer ours and humanity’s health trajectory in a much better direction.
