I occasionally enjoy a vegan meal, especially when traveling in Eastern Europe. But as an O+, I have found that the paleo diet works best for me. I have blood panels done semi annually and my levels are superb, esp. my HDL/trig ratio. I only buy Meat and chicken from organic, local farmers and, being in the PNW, I eat a lot of freshly-caught king salmon and halibut. Also, significant amounts of fresh vegetables, especially of the cruciform variety.
