Organic Food: More Nutritious

The Quality Low Input Food project, the biggest of its kind, took a 725-acre farm in north-east England, grew conventional produce (like cabbage, lettuce, potatoes and what) next to organic produce, and compared the results.

The biggest contrast was found for milk. The study found that levels of antioxidants in milk from organic cattle were between 50% and 80% higher than conventional milk (60% to 80% more nutrients in the summer than conventional milk, and 50% to 60% more in the winter). Organic milk also has higher levels of vitamin E, and 60 percent more antioxidants and desirable fatty acids. Antioxidants help with a healthy circulatory system and help keep cancer and heart disease away.

Other highlights:

1. Fruit and vegetables contain up to 40% more nutrients if they are grown without chemical fertilizers and pesticides.
2. Up to 40% more antioxidants could be found in organic fruit and vegetables than in those conventionally farmed.
3. Potatoes, kiwi fruit and carrots were among the organic produce found to be higher in vitamin C.
4. Higher levels of minerals and antioxidants were found in organically- farmed lettuce, spinach and cabbage. Organic spinach and cabbage have more minerals.
5. Organic produce also had higher levels of iron and zinc, vital nutrients lacking in many people's diets.
6. Organic cheese can have up to twice as many nutrients than conventional varieties.
7. Organic tomatoes, wheat, potatoes, cabbage, onions and wheat have 20 to 40 per cent more antioxidants than conventional fruit and vegetables.

Weight Management Reduces Risk of Cancer

WEDNESDAY, Oct. 31 from HealthDay News -- Weight management, exercise and proper nutrition are key to reducing your risk of cancer. And the earlier in life you adopt these practices, the better off you'll be, a new study suggests.

Factors such as birth weight, childbearing, breast-feeding, and adult height and weight also influence cancer risk, according to the report released Wednesday by the American Institute for Cancer Research and the Britain-based World Cancer Research Fund (WCRF). Understanding how these factors affect cancer risk, and how to put this information to use to prevent the disease, offer promising new directions for cancer research, the study authors said.

The WCRF said obesity can be linked to six types of cancer, five more than its last report, 10 years ago.

"We need to think about cancer as the product of many long-term influences, not as something that 'just happens,' " Dr. Walter J. Willett said in a prepared statement. Willett, a professor of epidemiology and nutrition at the Harvard School of Public Health, was one of 21 authors of the report, Food, Nutrition, Physical Activity, and the Prevention of Cancer: A Global Perspective.

"Examining the causes of cancer this way, across the entire lifetime, is called the life course approach," he added.

Among the new types are colorectal (bowel) and post-menopausal breast cancer.

The report, an analysis by scientists from around the world of more than 7,000 studies, offers 10 recommendations to help prevent cancer. They include staying lean, getting at least 30 minutes of exercise daily, limiting your intake of red meat and alcohol, and avoiding processed meats.

"These findings are right on," said Colleen Doyle, director of nutrition and physical activity at the American Cancer Society. "They are consistent with our own nutrition and physical activity guidelines. They clearly put the emphasis where the emphasis needs to be, and that's on controlling your weight."

"This is a good-news report," added Karen Collins, a nutrition adviser at the American Institute for Cancer Research. "If we are watching our weight, working regular physical activity into our daily life and eating a healthy balance of foods, we could prevent a third of cancers," she said. "Extra weight is not dead weight," she said. "It's an active metabolic tissue that produces substances that promote the development of cancer."

"People should take this message to be empowering," Collins said.
