INSIGHT

Traffic Light Food System

  • Dr. Greger uses a traffic light system to classify foods as green (go), yellow (caution), and red (stop).
  • Green means eat more whole plant foods; red means avoid processed and unhealthy foods.

Plants and Processing Matter

  • Plant foods generally contain protective nutrients and fewer disease-promoting factors than animal foods.
  • Unprocessed foods tend to be healthier than processed foods, but there are exceptions.

Processing Can Harm or Help

  • Processing often removes nutrients, like milling whole grains to white flour, which caused diseases like beriberi.
  • But some processing, like making tomato juice, can boost nutrient availability.
