Suppose A new study published in the Journal of Nutrition suggests that a diet high in whole grains can lower the risk of developing type 2 diabetes. The study followed over 10,000 participants for a period of 10 years and found that those who consumed more whole grains had a 30% lower risk of diabetes compared to those who consumed refined grains.
Can we infer that "Eating whole grains is the only factor that influences the risk of developing type 2 diabetes."? Yes, no, or maybe?
