Meat lovers and others who want to live a longer life should eat meat from ruminants. Ruminants are animals with 4 stomachs who chew the cud. The benefit is from the 4 stomachs actually breaking down and "pickling" the food that they are eating. This pickling causes all kinds of micro-biological nutrients to be created in the stomachs - micro-biological nutrients that aren't found in plants, except possibly in tiny quantities. These nutrients are passed into the meat of the ruminants, and then to the people who eat ruminant meat. - https://duckduckgo.com/?q=ruminants&ia=definition - Many good articles at this search site.
