Dr. Martin shares an interesting observational study about colorectal cancer in today's episode.

The populations of India and Pakistan are known for having very high rates of diabetes. They share similar diets, but it turns out that India has 400% more colorectal cancer than in Pakistan.

Why is this you may ask? Indians generally eat much less meat than their Pakistani neighbours because of their religious beliefs. Pakistan is almost a 100% Muslim population and they eat more meat.
