During food irradiation, food is exposed to very high doses of radiation, in the form of gamma rays, X-rays or electron beams. Irradiation can kill nearly all bacteria in food, both good and bad (yes, some bacteria is good for you!), but it is helpless against mad cow disease and viruses i like foot and mouth disease and hepatitis.
How is food irradiation different from microwaving?
The main purpose of food irradiation is to preserve foods and extend the shelf life of products. Food irradiation is considered to be a "cold" process because it achieves its effect with hardly any increase in the irradiated foods' temperatures. It uses gamma rays with short wavelengths and high frequencies that penetrate food so rapidly that little or no heat is produced. Microwave radiation uses longer wavelengths and less energy than irradiation. Unlike irradiation, microwaving causes foods to heat rapidly, and they can undergo changes in texture and shape as well. For example, microwaved corn kernels change shape and texture as they become hot popcorn. ii

Why Large Amounts of Fruit May Not Be Healthy

The editorial linked below appeared in the American Journal of Clinical Nutrition. It traces the rise in fructose consumption, and the rise in chronic diseases that have come in its wake.
Fructose is a simple sugar found in honey, fruit, table sugar, and high-fructose corn syrup (HFCS). Because of the increase in the consumption of these sweeteners, fructose intake worldwide has quadrupled since the early 1900s.
Over the past three decades, there has been an even greater acceleration in consumption, in part because of the introduction of HFCS. The increase in fructose consumption parallels the rise in obesity, diabetes, hypertension, and kidney disease.
Studies in animals have shown that fructose can induce insulin resistance, elevated triglycerides, abdominal obesity, elevated blood pressure, inflammation, oxidative stress, endothelial dysfunction, microvascular disease, hyperuricemia, glomerular hypertension and renal injury, and fatty liver. The consumption of large amounts of dietary fructose also can rapidly induce insulin resistance.

Six Ways to Reduce Inflammation -- Without a Statin Drug
|
Experts predict that as a result of the so-called JUPITER study, which seemed to show that the statin drug Crestor lowers the risk of heart attacks and strokes in those with high levels of inflammation, will lead to millions of people being put on statin drugs.
But the benefits were actually tiny -- about 0.72 percent of the statin takers in the trial had a heart attack or stroke, compared with 1.5 percent of those taking placebos.
Instead of a statin drug that comes with dangerous side effects, try these six measures instead:
-
- Stop smoking. Smoking hardens the arteries and increase inflammation. But research shows you can reverse all the damaging effects to your arteries within 10 years of quitting.
- Think olive oil, fish, and nuts. People who stick with a Mediterranean-style diet based on fruits, vegetables, nuts, and olive oil can lower their levels of inflammation. It works by increasing the amount of foods you eat that are rich in omega-3 fats, which fight inflammation.
- Get active. Exercise a great way to lower inflammation without any of the side effects associated with medications.
- Shrink your waist size. If you're a woman with a waist measurement of over 35 inches or a man with a waist of over 40 inches, you probably have high inflammation. Whittling a few inches off the waist by reducing your portions and increasing activity can go a long way toward solving that problem.
- Get enough sleep. A new study shows that elderly people with high blood pressure who sleep less than 7.5 hours a night have dramatically elevated chances of having a stroke or heart attack. Other research has shown that both too little and too much sleep increases inflammation. The American Academy of Sleep Medicine says most adults need between seven and eight hours of sleep each night.
- Reduce stress. High levels of stress hormones can lead to the release of excess inflammatory chemicals.
