Cooking Veggies...No Big Deal

I admit. For a long time I thought cooking vegetables killed them. Not so according to Dr. Fuhrman. He explains:
The raw-food movement continues to make converts, thanks to a devoted group of individuals and celebrities who embrace the belief that an all-raw food diet is the best diet. The idea that stirs the most enthusiasm for this diet is the contention that cooking both destroys about fifty percent of the nutrients in food, and destroys all or most of the life promoting enzymes.
Now, what about these enzymes? More from Dr. Fuhrman:
Contrary to what many raw-food web sites claim, the enzymes contained in the plants we eat do not catalyze chemical reactions that occur in humans. The plant enzymes merely are broken down into simpler molecules by our own powerful digestive juices. Even when the food is consumed raw, plant enzymes do not aid in their own digestion inside the human body. It is not true that eating raw food demands less enzyme production by your body, and dietary enzymes inactivated by cooking have an insignificant effect on your health and your body’s enzymes.
And here’s an interesting factoid, cooking can actually be beneficial. Dr. Fuhrman again:
In many cases, cooking destroys some of the harmful anti-nutrients that bind minerals in the gut and interfere with the utilization of nutrients. Destruction of these anti-nutrients increases absorption. Steaming vegetables and making vegetable soups breaks down cellulose and alters the plants’ cell structures so that fewer of your own enzymes are needed to digest the food, not more. The point is that this “cooked food is dead food” enzyme argument does not hold water. On the other hand, the roasting of nuts and the baking of cereals does reduce availability and absorbability of protein.
Get a load of this. Some new research has also determined that cooking vegetables might not damage their nutrient-load. More from CBS News:
The University of Parma's Nicoletta Pellegrini, PhD, and colleagues bought freshly harvested carrots, zucchini, and broccoli at a local market.

In their lab, the scientists measured levels of various antioxidants in the raw vegetables. Then they boiled, steamed, or fried the vegetables. Lastly, they measured antioxidant levels in the cooked vegetables.

Raw vegetables were loaded with antioxidants. After cooking, their antioxidant levels were a mixed bag.

In some cases, the veggies lost antioxidants to cooking. But not all antioxidants decreased when cooked -- and in some cases, certain antioxidant
levels rose when cooked.
Okay, this post isn’t intended to bash raw food—heck, Dr. Fuhrman eats plenty of raw veggies—in fact, he’ll tell you first hand, raw food is wonderful! Here’s one last quote:
Certainly, there are benefits to consuming plenty of raw fruits and vegetables. These foods supply us with high nutrient levels and the smallest number of calories. But the question we are looking at is this—Are there advantages to eating a diet of all raw foods and excluding all cooked foods?

Clearly, the answer is a resounding “No.” In fact, eating an exclusively raw-food diet is a disadvantage. To exclude all steamed vegetables and vegetable soups from your diet narrows the nutrient diversity of your diet and has a tendency to reduce the percentage of calories from vegetables, in favor of nuts and fruit, which are lower in nutrients per calorie.
I should point out, I’m eating a raw fruit and veggie chocolate pudding right now—YUM!

Bad News for Toxins

Will Dunham of Reuters reports, smoking increases your risk of developing diabetes. Here’s more:
Here's another reason to throw away the cigarettes: Smoking, already known to cause lung cancer, heart disease and stroke, also raises one's risk for the most common form of diabetes, researchers said on Tuesday.

Smokers faced a 44 percent increased risk of developing type 2 diabetes when compared to nonsmokers, the Swiss researchers found.

Dr. Carole Willi of the University of Lausanne in Switzerland and colleagues analyzed 25 studies exploring the connection between smoking and diabetes published between 1992 and 2006, with a total of 1.2 million participants tracked for up to 30 years.
High ozone levels seem to explain why some residents of Sydney Australia had sudden cardiac events. Reuters reports:
A sudden spate of urgent cardiovascular syndromes resulting in severe chest pain that required emergency department visits among residents of Sydney, Australia, in 2005 has been traced to high solar radiance and ozone levels.

Surveillance data indicated an increase in urgent visits to city hospitals by individuals with chest pain assessed as "imminently or immediately life-threatening on arrival" in April and May 2005, Dr. Robin M. Turner of New South Wales Department of Health in North Sydney and colleagues report in the journal Environmental Health.

Emergency department visits increased from 4.0 per day in 2004 to 5.7 per day for the 8 weeks of April and May 2005.
