I only drink water and tea with occasional coffee. No sugar in food/drinks. I love exploring new and interesting vegan recipes.
Minimize high GI (glycemic index). It spikes blood sugar and insulin.
Eat many healthy fats. Avocados, Flax seed oil, etc.
Eat lots of high quality protein.
The Academy of Nutrition and Dietetics, the largest professional organization for nutrition and dietary professionals, says plant-based diets can be safe and healthy at all stages of life. Additionally, a sizeable percentage of Seventh Day Adventists eat a plant-based diet, and population studies show that Adventists have overall excellent health. Evidence and scientific consensus are solidly on the side of plant-based diets being healthy.
So think about it this way, all of the animals people eat are herbivores, they eat plants only. All of the nutrients in animal products come from the plants they eat. All you're doing is cutting out the middle man and putting those plant nutrients directly into your body. On the B12 issue, most animal feeds are supplemented with it because they no longer graze on pasture where they would get it naturally. So again, you can take the supplement yourself or through an intermediary.
Final note, according to Michael Pollan unless you are actively ill with diabetes, heart disease, or some other ailment this diet can help, there is a negligible difference between a full whole foods vegan diet and someone who eats up to 10% of their calories from animal products. Personally I wouldn't for moral reasons. It's anecdotal but I reversed pre-diabetes and lost 40lbs eating this way and I have all of my blood levels done yearly. ALL of my markers are significantly better than before I was plant based.
Highlights from high-carb diet may explain why Okinawans live so long article:
sweet potato, rather than rice, is high-consumption food in the Okinawan diet
high engagement in agriculture and fishing jobs → high physical activity
possible effects of genetics — high presence of FOXO3 gene
10-to-1 carbs-to-protein consumption ratio, like in other particularly-long-lived populations – linked studies support the conclusion, though too early to judge definitively
most of the diet is vegetables and fruits; meats and fish are rare
calorie consumption is, on average, 13% lower than general population
studies suggest that plant-based protein intake have a more positive effect on the human organism than meat- and fished-based
their diet is not the "elixir of youth", as multiple interacting factors may be in play
