Benefits of Beets

My beets are ready now, and the link given below by jfh had good information about the benefits of them. I knew they were good for the liver, but this tells better why they are.


THere's more, but here's some of the information:

Promote Optimal Health

The pigment that gives beets their rich, purple-crimson color-betacyanin-is also a powerful cancer-fighting agent. Beets' potential effectiveness against colon cancer, in particular, has been demonstrated in several studies.

In one study, animals under the double stress of chemically induced colon cancer and high cholesterol were divided into two groups. One group received a diet high in beet fiber while the other group served as a control. The beet fiber-fed animals rose to the challenge by increasing their activity of two antioxidant enzymes in the liver, glutathione peroxidase and glutathione-S-transferase. The liver is the body's primary detoxification organ where toxic substances are broken down and eliminated, a process that generates a lot of free radicals. Glutathione peroxidase and glutathione-S-transferase are the bodyguards for liver cells, protecting them from free radical attack, so they can continue to protect us.

In other animal studies, scientists have noted that animals fed beet fiber had an increase in their number of colonic CD8 cells, special immune cells responsible for detecting and eliminating abnormal cells. With the increased surveillance provided by these additional CD8 cells, the animals in one of the studies given beet fiber had fewer pre-cancerous changes.

In stomach cancer patients, when scientists compared the effects of fruit and vegetable juices on the formation of nitrosamines, cancer-causing compounds produced in the stomach from chemicals called nitrates, beet juice was found to be a potent inhibitor of the cell mutations caused by these compounds. Nitrates are commonly used as a chemical preservative in processed meats.

Protection Against Heart Disease

In the first study mentioned above, not only did protective antioxidant activity increase in the livers of beet fiber-fed animals, but also their total cholesterol dropped 30%, their triglycerides dropped 40% (elevated triglycerides, the form in which fats are transported in the blood, are a significant risk factor for cardiovascular disease), and their HDL (beneficial cholesterol) level increased significantly.

Beets' Betaine Helps Lessen Inflammation

People whose diets supplied the highest average intake of choline (found in egg yolk and soybeans), and its metabolite betaine (found naturally in vegetables such as beets and spinach), have levels of inflammatory markers at least 20% lower than subjects with the lowest average intakes, report Greek researchers in the American Journal of Clinical Nutrition (Detopoulou P, Panagiotakos DB, et al.)

Compared to those whose diets contained <250 mg/day of choline, subjects whose diets supplied >310 mg of choline daily had, on average:

22% lower concentrations of C-reactive protein
26% lower concentrations of interleukin-6
6% lower concentrations of tumor necrosis factor alpha
Compared to those consuming <260 mg/day of betaine, subjects whose diets provided >360 mg per day of betaine had, on average:

10% lower concentrations of homocysteine
19% lower concentrations of C-reactive protein
12% lower concentrations of tumor necrosis factor alpha
Each of these markers of chronic inflammation has been linked to a wide range of conditions including heart disease, osteoporosis, cognitive decline and Alzheimer's, and type-2 diabetes.

In an accompanying editorial in the American Journal of Clinical Nutrition entitled, "Is there a new component of the Mediterranean diet that reduces inflammation?," Steven Zeisel from the University of North Carolina at Chapel Hill noted that choline and betaine work together in the cellular process of methylation, which is not only responsible for the removal of homocysteine, but is involved in turning off the promoter regions of genes involved in inflammation.

"Exposure to oxidative stress is a potent trigger for inflammation. Betaine is formed from choline within the mitochondria , and this oxidation contributes to mitochondrial redox status ," Zeisel continued.

"If the association between choline and betaine and inflammation can be confirmed in studies of other populations, an interesting new dietary approach may be available for reducing chronic diseases associated with inflammation," he concluded.

Recommended daily intakes of choline were set in 1998 at 550 milligrams per day for men and 425 milligrams a day for women. No RDI has been set for betaine, which, since it is a metabolite of choline, is not considered an essential nutrient.

Practical Tip: Egg yolks are the richest source of choline, followed by soybeans. Beets, spinach and whole wheat products are primary sources of betaine. (Olthof MR, van Vliet T, et al. J Nutr)

Protection against Birth Defects

Beets are particularly rich in the B vitamin folate, which is essential for normal tissue growth. Eating folate-rich
