Why do people take barley?

People take barley to try to lower:

People also take barley to try to promote weight loss or help prevent some types of cancer.

Barley is probably effective at reducing total cholesterol and LDL "bad" cholesterol. It may also lower triglycerides and increase HDL "good" cholesterol levels, but the research has been mixed. How much it lowers cholesterol may depend upon how many grams you eat. The effect may also be less when barley is highly processed.

Barley may also lower blood pressure in people who do not have high blood pressure but do have high cholesterol.

Fiber in foods, such as in barley, may help prevent stomach cancer or prolong life in those with the disease. But it doesn't seem to protect against colorectal cancer.

Researchers have not yet proven barley's effectiveness for other purposes. But barley may help control appetite by stabilizing blood sugar and by slowing the emptying of your stomach.

Optimal doses of barley as a food or supplement have not been established for any condition.

However, to try to lower cholesterol, people have used one of these daily doses:

  • 3 grams of barley oil extract
  • 30 grams of barley bran flour
  • 0.4 to 6 grams of soluble barley fiber
  • 3 to 12 grams of pearled barley, or barley flour, flakes, or powder

To try to lower blood pressure, people with moderately high cholesterol have taken 3 to 6 grams daily of:

  • Barley flakes
  • Barley flour
  • Pearled barley

At the same time, they eat a low-fat, low-cholesterol diet.
