To begin, not eating is surprisingly the way to get healthy, not eating provides more benefit to health than eating. Malnutrition is not healthy. In nations that eat too much and nations that are malnutrition are both deleterious to heath and longevity. The more money you have the longer you will likely live and this is down to placebo which plays a significant role in health and longevity.
However, let's discuss diet. The vegan diet is by far the best diet.
The vegan diet is the wholefood diet, comprised of low sugar fruits and vegetables, nuts and legumes and medicinal plants and herbs as they arrive with minimal processing, not strictly such as extra virgin olive oil to season salads and similar. They are not faux animals products, nor are they sugar sweets. They are not rice, bread, coke and fries. The vegan diet is incomplete, and vegans must be enterprising to complete the vegan diet.
Vegans cannot source Vitamin B12 from the plant sources. The efforts to resolve these issues are...
- Take a Vitamin B12 or a B-Complex pill supplement
- There are exotic forms of B12 in plants, e.g. the water lentil. Such low B12 plant source would need to be re-engineered to produce more B12. Water lentils could be in a spice powder seasoning format.
