According to the American Dietetic Association position paper on vegetarian diets, people who eat a vegetarian diet have a lower risk of developing heart disease, Type 2 diabetes and high blood pressure. They also tend to have lower LDL cholesterol levels, body mass index (BMI) readings and overall cancer rates (1). However, when it comes to a vegetarian diet, there are right and wrong ways to go about adopting this (largely) healthful way of eating. For this reason, education on a healthful vegetarian diet is critical.
A 2005 poll showed that 3 percent of 8- to 18-year-old children were vegetarians (1). While it's been well established that a vegetarian diet can be healthful and adequate in nutrition, children and teens do require age-appropriate intakes of certain nutrients. Especially important for vegetarians are: protein, calcium, iron, zinc, Vitamin D and Vitamin B12 in amounts sufficient to support growth and development. Guidance from parents in making deliberate food choices helps maintain balance and variety, ensuring that nutritional needs are met. If your child has decided to "go veg," here are the nutrition considerations that need to be taken into account:

Unhealthy veg*ns are usually ones who never learned about or fall in love with all that amazing food we never heard about in school or at home! A few tips:
1. Don't try to just replace animal products with vegans ones. Vegan sausages can be nice but don't rely on them!
2. Try everything more than once, you really can't expect to make vegan food taste amazing the first time, keep experimenting and don't give up...
3. Wikipedia is a great place to learn with great lists of vegetables, nuts, seeds, etc.
4. Check out the USDA Nutrient Database - Thousands of foods nutritionally analysed. Ever wondered what's in broccoli? Probably not, but this will tell you! http://www.nal.usda.gov/fnic/foodcomp/search/
5. Join veggie/vegan forums, people who have years of experience will be happy to help you and share their favourite recipe tips.
I'm here to share & learn.... so daft comments and insults will be ignored. ;-)
With the exception of white rice I would stay away from grains because they have phytates which bind with minerals and make the mineral bio-unavailable for your body to absorb. The harsh insoluble fiber can may also damage your digestive track as well.
Don't even get me started on what grains do to nutrients in the body.
So all of these should be off the menu?
The cavemen who never ate those things either also took a remarkably long time to think up the wheel, reliable medicine, just laws, science not to mention your clothes, your house, electricity, anti-biotics (if you are over 25 you have lived far longer than the majority of them and probably have unnatural medicines to thank for that) and lets not forget how they also didn't invent your computer
:-)
I don't think there is a sound scientific basis for your claim at all. All these lovely things rely on agronomy - not hunting for meat. Agronomy is quite 'unnatural'.
The only hint of science I spotted in your comment was a cursory mention of the nutritional requirements of our bodies which you didn't detail. I personally meet my bodies nutritional requirements by giving it nutrients... which luckily are abundant without relying on meat, thanks to those lovely unnatural plant foods intelligent people spent the last few thousand years improving.
:-P
The most common brand is Red Star, and you can find it on the shelves of any health food store or organic section of the supermarket. Some health food stores sell it in bulk.
Within 3 days of his decision to eat meat again there was an amazing difference. Im sorry it might have some health benefits to certain individuals if done correctly but I also feel most people need some form of animal protein to remain healthy
I am not saying you didn't solve your problem (as you say you did) but honestly, doctors offices are filled with far far FAR more people with health problems of all kinds (and virility problems) who are carnivores. There is no denying that when done right, vegetarian/vegan people are just healthier. But you have to really do it right, know your protein grains, your veggies, where your calcium sources are. In other words: be educated about health. Which one should do, regardless of being veg or carnivore.

Recently, I'm just eating a lot more simple. I'm a good cook and use to go all out. But now a nice salad, green juice, rice and beans, raw veggies or fruit is doing the trick.
