“10 grams/day was Pauling’s recommendation (He died of prostate cancer - at age 93). It would take 5000 cups of shredded Romaine lettuce, or 80 cups of orange juice to get that amount.”

Ok now I doubt pretty much everything you say. If we really needed to ingest that much to avoid a fatal condition, then the human race would have died out long before we invented supplements. Actually, if that were true, the mutation that stripped us of the ability to synthesize vitamin C could never have gained prevalence in the human population, due to natural selection. Obviously, if it became a ubiquitous mutation, it must not have much negative impact on us at all, considering our normal eating habits.

Natural selection can allow a population to survive if a condition doesn't kill them until they've passed sexual maturity and can produce children and live long enough to get them sexual maturity. Arteriosclerosis takes longer than that to cause death. Some studies. Autopsies performed on casualties of the Korean War revealed coronary artery involvement in 77.3% of the hearts studied, and data after the Vietnam War noted the presence of atherosclerosis in 45% of casualties with severe disease in 5%..

Science isn't easy.
