A most interesting and challenging article called Raw versus Cooked Foods: Which is Better? came across my desktop. When Dr. Bruce Ames from UCLA was quoted, I took special notice as I have had much respect for his work.
I think every one knows eating raw fruits and vegetables is healthy and nutritious; but few may know why. (I always feel very much energized after eating a small plate of veggies with dip– as well as a banana, apple or orange.) Some even find properly prepared raw meat (such as beef liver, oysters or sushi) to be beneficial.
Personally, I would never become a raw foodie, as some swear by and avoid anything cooked–some religiously (“don’t touch that– cooked green beans have been on that plate”). I would rather increase consumption of raw, and continue eating al dente many of the veggies.
The info contained in this wonderful article is based on a lot of testing and research. Although much of it I am sure is true, I think the article omits the facts that when something is properly cooked it makes digestion easier and increase absorption of other nutrients, I still would rather have my grass-fed Porter Houses charbroiled on the grill at medium rare with lots of cancer-causing char on the outside– and take the risk it might take 10 days off my life.
The article mentions that about 120 degrees F is the cooking max, go figure. An African reader commented here (somewhere) that you can cook potatoes in a cast iron, covered skillet in the hot sun– although that could reach 180 degrees.
Here is an excerpt:
Excessive Heat Denatures Nutrients
Burn your finger and skin tissue dies. Overly apply heat to food and nutrients are progressively destroyed. Fresh food prior to wilting or rotting sustains life to a high degree of wellness. Harvested food from field and orchard provides raw materials to replenish your cells and tissues. Overly cooking food destroys live plant and animal tissue whose nutrients no longer bear any relationship to your living body. A diet containing an abundance of raw, unfired food maximizes well being.
The chemical changes that take place to individual nutrients, as excessive heat is applied will now be examined. It is well understood and recognized in scientific literature that heat breaks down vitamins, amino acids and produces undesirable cross-linkages in proteins, particularly in meat. When food is cooked above 117 degrees F for three minutes or longer, the following deleterious changes begin, and progressively cause increased nutritional damage as higher temperatures are applied over prolonged periods of time: ï‚· proteins coagulate, ï‚· high temperatures denature protein molecular structure, leading to deficiency of some essential amino acids, ï‚· carbohydrates caramelize, ï‚· overly heated fats generate numerous carcinogens including acrolein, nitrosamines, hydrocarbons, and benzopyrene (one of the most potent cancer-causing agents known), ï‚· natural fibers break down, cellulose is completely changed from its natural condition: it loses its ability to sweep the alimentary canal clean, ï‚· 30% to 50% of vitamins and minerals are destroyed, ï‚· 100% of enzymes are damaged, ï‚· the bodyâ€™s enzyme potential is depleted which drains energy needed to maintain and repair tissue and organ systems, thereby shortening our life span, ï‚· pesticides are restructured into even more toxic compounds, ï‚· valuable oxygen is lost, ï‚· free radicals are produced, ï‚· cooked food pathogens enervate the immune system, ï‚· heat degenerates nucleic acids and chlorophyll, ï‚· cooking causes inorganic mineral elements to enter the blood and circulate through the system, which settle in the arteries and veins, causing arteries to lose their pliability, ï‚· the body prematurely ages as this inorganic matter is deposited in various joints or accumulates within internal organs, including the heart valves.
As temperature rises, each of these damaging events reduces the availability of individual nutrients. Modern food processing not only strips away natural anti-cancer agents, but searing heat forms potent cancer-producing chemicals in the process. Alien food substances are created that the body cannot metabolize.
