Question

We are one hundred percent vegetarian and so are getting the advantages mentioned by you.
Do you think vegetarians have a better health on an average with those compared to the non-vegetarians?

Answer

This is a deep and complex subject with many different ways of looking at it. Here are some of my thoughts.

Species Specific
When you look at human teeth, they are much more like horses (herbivores) than cats (carnivores). This means that our diet should be more focussed on plant based food than animal based food. This is also upheld by our intestines. Short intestines are suitable for raw meat, which comes pre-digested, if you like. Plant based food takes longer to digest than raw meat. Our intestines are much longer than carnivores (proportionately), showing that our food should be mostly plant based.

However, we are able to digest meat. Our closest cousins, the chimpanzees do go hunting occasionally - perhaps once a week or once a month depending on where they live and what is available.

Whole Food
However, ALL carnivores consume bones along with the meat. Meat needs large amounts of calcium to digest. Humans, in our infinite wisdom, have removed the bones from the food. This means that to digest meat, calcium is leached from our teeth and bones. No wonder osteoporosis is so common.

Raw Food
Cooking not only destroys many nutrients, it alters protein. So raw meat is much healthier to eat.

Compassion, Ethics and Farmed Animals
The food we eat contains the energy that went into its production. Farmed animals are, for the most part, treated with great cruelty, with a total lack of compassion. This, along with all the antibiotics and hormones that are so commonly used to increase rapid weight gain, and so profit, is passed on to the consumer.
Can this be healthy for you?

Cancer
Some people feel that cancer is caused by a nutrition deficiency. Although I don't personally agree with this, I do feel that it can contribute to it. How can you be healthy on the common diet of modern humanity - high sugar, high fat, virtually all processed food, high animal protein, scant regard to fresh produce, little compassion for the animal providing the food.
All forward thinking practitioners will put their cancer patients on a vegetarian or vegan diet. This speaks for itself.

Protein
It is a common belief that only animal protein can provide you with sufficient protein. As many top performing athletes are turning vegan, they are finding that their performance improves. This means that everyone can get their protein from plant based food. All vegetables are high in protein, but some more so than others. Nuts and seeds are high in protein.
All plant based food which contains protein, also contains calcium, as well as all the other nutrients essential to a complete and balance digestion and utilisation by the body.

Calcium
People often consider that dairy is the best source of calcium. However dairy is meant for babies. Of the same species. Cows and humans are physiologically very different. Once an infant is weaned, dairy is no longer easily digested, or utilised. The best source of calcium is green leafy vegetables, blue-green algae and nuts and seeds. Not only is the calcium easily absorbed and utilised by the body, these are all whole foods, with all the supporting and essential nutrients.

Environment
It takes much less land and natural resources to grow enough plant based food for people than it does to grow farm animals. So a vegan diet is good for our planet with its burgeoning population.

In conclusion, I feel that a vegetarian/vegan diet is not only more healthy for you, but also for the planet. However, occasional animal protein (once a week or less often), as long as it is from ethical and humane sources, and preferably raw, is unlikely to harm you and may be helpful.
