Today I stopped by Baja Fresh and had the cheapest, most delicious lunch. For $2.88 I had a huge plate of black beans topped with a large side of fresh guacamole and three different kinds of fresh salsa. Sprinkled on top was fresh chopped cilantro.
I could barely finish the entire plate of beans. I left with a full stomach and lots of nutrients about to circulate through me! Black beans are really good for you. Here is what the experts say:
"Black beans are a very good source of cholesterol-lowering fiber, as are most other legumes. In addition to lowering cholesterol, black beans' high fiber content prevents blood sugar levels from rising too rapidly after a meal, making these beans an especially good choice for individuals with diabetes, insulin resistance or hypoglycemia. When combined with whole grains such as brown rice, black beans provide virtually fat-free high quality protein. You may already be familiar with beans' fiber and protein, but this is far from all black beans have to offer.
Sensitive to Sulfites? Black Beans May Help
Black beans are an excellent source of the trace mineral, molybdenum, an integral component of the enzyme sulfite oxidase, which is responsible for detoxifying sulfites. Sulfites are a type of preservative commonly added to prepared foods like delicatessen salads and salad bars. Persons who are sensitive to sulfites in these foods may experience rapid heartbeat, headache or disorientation if sulfites are unwittingly consumed. If you have ever reacted to sulfites, it may be because your molybdenum stores are insufficient to detoxify them. A cup of black beans will give you 172.0% of the daily value for this helpful trace mineral.
A Fiber All Star
Check a chart of the fiber content in foods; you'll see legumes leading the pack. Black beans, like other beans, are rich in dietary fiber. For this reason, black beans and other beans are useful foods for people with irregular glucose metabolism, such as diabetics and those with hypoglycemia, because beans have a low glycemic index rating. This means that blood glucose (blood sugar) does not rise as high after eating beans as it does when compared to white bread. This beneficial effect is probably due to two factors: the presence of higher amounts of absorption-slowing protein in the beans, and their high soluble fiber content.
Soluble fiber absorbs water in the stomach forming a gel that slows down the metabolism of the bean's carbohydrates. The presence of fiber is also the primary factor in the cholesterol-lowering power of beans. Fiber binds with the bile acids that are used to make cholesterol. Fiber isn't absorbed, so when it exits the body in the feces, it takes the bile acids with it. As a result, the body may end up with less cholesterol. Black beans also contain insoluble fiber, which research studies have shown not only helps to increase stool bulk and prevent constipation, but also helps prevent digestive disorders like irritable bowel syndrome and diverticulosis.
Loaded with Antioxidants
Research published in the Journal of Agriculture and Food Chemistry indicates that black beans are as rich in antioxidant compounds called anthocyanins as grapes and cranberries, fruits long considered antioxidant superstars.
When researchers analyzed different types of beans, they found that, the darker the bean's seed coat, the higher its level of antioxidant activity. Gram for gram, black beans were found to have the most antioxidant activity, followed in descending order by red, brown, yellow, and white beans.
Overall, the level of antioxidants found in black beans in this study is approximately 10 times that found in an equivalent amount of oranges, and comparable to that found in an equivalent amount of grapes or cranberries.
Promote Optimal Health
A study published in Food Chemistry and Toxicology suggests not only that black beans may help protect against cancer, but that whole foods naturally contain an array of compounds that work together for our benefit. When researchers fed laboratory animals a 20% black bean diet to see if it would cause any mutagenic or genotoxic activity, not only did black beans not promote cancer, but a clear reduction in the number of pre-cancerous cells was seen, even in animals who were simultaneously given an agent known to promote cancer, the mutagen, cyclophosphamide.
In an attempt to identify the bean components responsible for this protective effect, the researchers tested a single commercial anthocyanin, but instead of being protective on its own, the flavonoid, at the highest dose administered (50 mg per kg of bodyweight), actually induced DNA damage. The moral we draw from this tale: the synergy of compounds brought together by Mother Nature in the creation of whole foods is highly likely to be of greater benefit than a single extracted compound.
Lower Your Heart Attack Risk
In a study that examined food intake patterns and risk of death from coronary heart disease, researchers followed more than 16,000 middle-aged men in the U.S., Finland, The Netherlands, Italy, former Yugoslavia, Greece and Japan for 25 years. Typical food patterns were: higher consumption of dairy products in Northern Europe; higher consumption of meat in the U.S.; higher consumption of vegetables, legumes, fish, and wine in Southern Europe; and higher consumption of cereals, soy products, and fish in Japan. When researchers analyzed this data in relation to the risk of death from heart disease, they found that higher consumption of legumes was associated with a whopping 82% reduction in risk!
Check out Baja Fresh for lots of bean dishes. Chipotle and Anita's are also good choices.
