If Americans ate just one more serving of fruits or vegetables per day, this would save more than 30,000 lives and $5 billion in medical costs each year.
If Americans were to follow current USDA recommendations for daily consumption of fruits and vegetables, those numbers would go up to more than 127,000 lives and $17 billion saved.
The increased longevity that would result if Americans ate the recommended amount of fruits and vegetables is worth over $11 trillion.
An enterotype is a classification of living organisms based on its bacteriological ecosystem in the gut microbiome. Humans can be roughly divided into three enterotypes depending on which genus of bacteria dominates their gut: Bacteroides, Ruminococcus, or Prevotella.
- People who eat a lot of meat and saturated fat tended to have more Bacteroides in their flora.
- Ruminococcus prevailed in people who consumed lots of alcohol and polyunsaturated fats.
- Prevotella favored a diet rich in carbohydrates.
Long-term diet is strongly associated with the gut microbiome composition. If switching gut enterotype is possible, it may take a long-term dietary intervention.
Chimpanzees have enterotypes that are compositionally analogous to those found in humans.
