Several studies have now shown that vegetarians, and especially vegans, have better biomarkers than meat eaters. OK, great, but what the heck is a biomarker?
A biomarker is a chemical substance found in blood, other body fluids, or tissues that is a sign of either disease or health. The good news is that vegetarians and vegans have more of the biomarkers that indicate good health and less of the ones that indicate a disease process.
Studies have shown that vegans and vegetarians have lower levels of biomarkers that indicate inflammation, heart disease, diabetes, kidney disease and other diseases such as rheumatoid arthritis than meat eaters. This puts them at a lower risk of getting these diseases.
Even more impressive is a recent study that showed that vegetarians appear to have a healthier biomarker profile than meat-eaters for adults of any age and weight, and is also unaffected by smoking and alcohol consumption. Now this does not mean vegetarians can go out and start smoking and abusing alcohol, but it does show the power of a plant- based diet and that the greater positive health impact of a vegetarian diet can even outweigh the negative effect of smoking and alcohol consumption.
