Much of the wisdom in the divine design for meats was confirmed by a 1953 study in which Dr David Macht of John Hopkins University reported the toxic effects of animal flesh on a controlled growth culture. A substance was classified as toxic if it slowed the culture’s growth rate below 75 percent. In each case, the blood of all animals Dr Macht tested showed up more toxic that the flesh.The results show that the lower the growth percentage of the culture, the more toxic the flesh. Note that the flesh of animals and fish given to us by God for food are all non-toxic, but all the forbidden animals lie in the toxic range. (Animals without percentage rankings in the chart were not studied, but are included here to provide a more comprehensive list of clean and unclean meats.)
Don’t get confused: any number above 75% is non-toxic or clean to eat
Below 2 charts should make it easy for us to identify which meats we should choose to eat. It also makes it apparent that we are eating many toxic substances that were not created for food.
The difference between clean and unclean animals appear to be related to their primary food source and to their digestive systems. Scavengers that eat anything and everything are unclean, not suitable for food, according to the Bible. Animals described as clean and therefore good for food, primarily eat grasses and grains.
This examination of clean and unclean flesh could be a more revealing study considering today’s modern toxicologic technology.
A loving God protects His people by showing them just which foods are safe.
He summarized His will in Leviticus Chapter 11.
