In part one of “Vancouver: Raw food revolution in the making” the discussion related to the following (see part two below):
The people of Vancouver are awakening to a new revolution – a raw food revolution.
Raw food is essentially real food – nutritious living foods without contaminants, chemicals, and growth products unaltered by laboratory interventions, heat and processing.
Foodies are going back to their roots and changing their diet in an obvious yet dramatic way. The New Year 2010 has brought more focus on wellness, prevention and awareness of what happens to and through the body. The revolution in raw food eating can be observed in all hubs in the city of Vancouver.
In this article (part two), an introduction to raw foodism will be discussed. Here is an excerpt (in part) that covers excellent points not always mentioned with beginning this type of diet:
People must be aware that certain nutritional deficiencies can occur on the raw food diet, including:
-B12: The Journal of Nutrition study found that a raw food diet increased levels of homocysteine due to vitamin B-12 deficiency.
Critics of the raw food diet say while it’s true that some enzymes are inactivated when food is heated, it doesn’t matter because the body uses its own enzymes for digestion. In addition, cooking makes certain phytochemicals easier to absorb, such as beta-carotene in carrots.
Another critique is that the human body has changed in response to eating cooked foods. Some of these changes are that are jaws and teeth have become smaller, our stomachs have shrunk, and our small intestines have grown longer, lengthening the digestive surface area.
According to other alternative diet theories, such as Macrobiotics, Ayurveda, and Traditional Chinese Medicine (TCM), a raw-only diet may not be appropriate for people living in colder climates or for people with certain constitutional types.
The raw food diet may not be appropriate for certain people, such as:
Pregnant or nursing women
People with [severe] anemia
People at risk for osteoporosis
Some people experience a detoxification reaction when they start the raw food diet, especially if their previous diet was rich in meat, sugar, and caffeine. Mild headaches, nausea, and cravings can occur but usually last for several days.
Typically, change in diet will allow the body to rest, recuperate and detoxify. A healthy amount of pure water is extremely important when practicing this diet, however most raw fruits and vegetables have enough water content to disable the idea of drinking large amounts, i.e. 6-8 glasses of water a day. Stress management, fitness resolutions, meditation and eight hours of sleep are simple and important methods to practice while taking part in raw foodism.
