Why are onions good for you?

An onion a day?

Sound a bit far-fetched? It's actually not such a bad idea healthwise. Onions are highly recommended for people trying to prevent cardiovascular disease, cancer and infections. Like most vegetables, sweet, yellow onions are fat- and cholesterol-free, and contain very little sodium.

The 4,000-Year-Old Healer

For over 4,000 years onions have been used for medical purposes. Egyptians numbered over 8000 onion-alleviated ailments. The esteemed Greek physician Hippocrates prescribed onions as a diuretic, wound healer and pneumonia fighter. During World War II, Russian soldiers applied onions to battle wounds as an antiseptic. And throughout the ages there have been countless folk remedies that have ascribed their curative powers to onions, such as putting a sliced onion under your pillow to fight off insomnia.

The Modern Day Preventative

Sweet onions are a member of the 500-plus allium family. While garlic, another allium, has been highly touted as a cancer preventative, most people consume far greater quantities of onions. As Americans search for low-fat, low-salt, but tasty meals, they're eating more onions - almost 18 pounds per person, which is 50% more than a decade ago.

Therefore, there is greater hope that the onion will be a key in producing long-term health benefits. In addition to tasting great, onions contain 25 active compounds that appear to inhibit the growth of cancerous cells, help combat heart disease, inhibit strokes, lower blood pressure and cholesterol, and stimulate the immune system. Alliums are also antibacterial and antifungal, so they can help ward off colds and relieve stomach upset and other gastrointestinal disorders.

What Makes Them So Good for You?

Of all the healthy benefits of onions, two elements stand out: sulfur (a compound) and quercetin (a flavonoid). They each have been shown to help neutralize the free radicals in the body, and protect the membranes of the body's cells from damage. Quercetin, an antioxidant, is also found in red wine and tea, but in much lower quantities. Interestingly, white onions contain very little quercetin, so it's better to stick with the yellow and red varieties. Most health professionals recommend eating raw onions for maximum benefit, but cooking makes them more versatile and doesn't significantly reduce their potency. In fact, unlike sulfur compounds, quercetin can withstand the heat of cooking. One researcher, Dr. Leonard Pike, director of the Vegetable Improvement Center at Texas A&M University, is working on producing onions with even higher levels of quercetin.

Onions And Your Heart

As with garlic, onions help prevent thrombosis and reduce hypertension, according to the American H eart Association. The juice of one yellow or white onion a day can raise HDL cholesterol (the good stuff) by 30% over time, according to Dr. Victor Gurewich, director of the Tufts University Vascular Laboratory at St. Elizabeth's Hospital in Boston. Red onions don't provide the same effect.

Sweet Onions - The Tasty Way to Better Health

What tastier way to eat healthier than with sweet onions. Because they are milder and easier to digest, you can consume "sweets" in abundance, thus obtaining all the many health benefits that these delicious alliums offer. Best of all, you won't shed any tears in the process.

Why are beets good for you?

Beets for Iron Health

Blood red and looking like a badly shaped tennis ball with a tail, beets are not high on the favorite foods list. They do show up in Aunt Mabel’s family reunion salad (which ranks right up there with fruitcake), but they are not found very often on dinner plates. Let’s face it, beets are a beaten vegetable.

To beat the beaten image, here are some unknown health benefits of the Beet.

The Facts: One cup of raw beets is high in carbohydrates and low in fat. It contains phosphorus, sodium, magnesium, calcium, iron, and potassium, as well as fiber, vitamins A and C, niacin, and biotin. Beets contain folic acid, which is recommended for pregnant women because it may lower the risk of spina bifida and other neural tube defects in newborn infants.

Heartbeet City

The Facts: According to John Heinerman, in the Encyclopedia of Healing Juices, beets (and beet juices) are a blood-building herb that detoxifies blood and renews it with minerals and natural sugars.

Dr. H.C.A. Vogel, in The Nature Doctor, States that beet juice contains betaine, which stimulates the function of liver cells and protects the liver and bile ducts. Recent studies point to betaine as contributing to the prevention of coronary and cerebral artery diseases.

Beeting the Big C

The Facts: Early research in Hungary indicated that beet juice and its powdered form slowed the development of tumors. Heinerman reports that Alexander Ferenczi, M.D., observed beets aiding cancer patients and performed studies that indicated that beets may help animals fight cancer.

Carrot juice is often used as a "base" juice in juice combinations, as its natural sweetness often masks unpleasant tastes. Many people mix carrot juice with beet juice for liver health.
