Amen! When do not follow the light given in Scripture reading health, we find that diet is important. Eating things that were never meant for us to eat causes disease. And, not only disease, but because the brain is not healthy, the mind does not function as it should. When we change our diet to follow what God intends for us to eat, the brain is being cleansed and the mind becomes more clear as to what is truth.
The Bible tells us that some food is clean and some unclean. That was true long ago. But, today because of sin, more things which were one time clean are no longer clean. Because of sin, the ways animals are raised they have become diseased. The food they eat and the water they drink are often not clean. Then when these animals and their eggs and milk are eaten by humans, their diseases are passed on to us. There are bacteria and viruses and prions that cause cancer and other diseases like Alzheimers that infect humans when in the animal products.
