There's no doubt based on the research done, that a nutritious diet is one that comprises a high complex-carbohydrate intake, having minimal protein (from plant matter) and fat intake. Meat (pork, fish, steak, lamb etc.) contains three to six times more dangerous, cholesterol-raising saturated fat. Before animals were sick, meat used to be a nutritious source of protein but now it carries a number of problems. The RDA (Required Daily Allowance) for protein is 45-60g, most people however; tend to eat 2-3 times more than this. The continual excessive amount of protein consumption in the diet is hard on the kidneys, promotes gout and causes calcium to be leached (drawn/removed) from the bones.
“Cooked and smoked meat products contain potentially harmful substances such as polycyclic aromatic hydrocarbons, heterocyclic amines and N-nitroso compounds which lead to degeneracy ” Clinical nutritionists, prove that since meat products have a low carbohydrate content, when it reaches the colon, it increases the ammonia concentration and this causes cell proliferation (rapid reproduction/multiplying) which in turn leads to cancer of the colon in the long run.
In the early 1900's, meat was still safe to eat, but as time has progressed, animal sicknesses like mad cow disease, bird flu, scrappy fish cancer among others have also increased, thus making it unsafe to eat. In our grandparent's day, animals were raised differently in farms and were allowed to graze all day eating organic food (grass etc.) whereas in most of today's holdings, the animals are kept in feedlots and cages with practically no exercise and are kept in unhygienic conditions with urea and droppings.
Drugs and antibiotics are used to make the animals grow at considerably fast rates. Modern animal husbandry treats animals as commodities since they are fed anything that promotes growth. Most of these animals are even deprived the natural process of mating and reproducing, and are artificially inseminated instead. This process of artificial insemination enables the animal to produce more off-spring than the animals original/natural capacity.
Animals fertilizers and pesticides used in the animal's food (no longer organic), contains harmful chemicals which are bad for both animal and consumers. The risk that is involved in contaminated animals and genetically engineered animals especially livestock, is something to consider. A diet free from animal products, and mainly comprising a variety of fresh whole foods is guaranteed to supply any individual with excellent nutrition as well as act as a protector against many of the most prevalent diseases associated with the Western diet.
