I don't understand how this is feasible. As a young healthy male I never had my full blood count have values anything other than within reference range. Even when I ate noodles everyday in college because I was broke, or now I eat balanced and healthy unprocessed food, veggies, lean meat etc I have similar blood counts. How do you measure a diet's effect within your lifetime? It seems like even if you look healthy by all measures a normal person is capable of measuring right now, but still be eating unhealthy.
