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.
