Background
As reported in JAMA, early phaseolamin products did not have sufficient potency or stability to effect any in vivo changes. In addition, impurities contained therein caused complaints of GI distress including flatulence. In the late 1990s, the first standardized starch blocker, "Phase 2 Carb Controller" (also known as StarchLite), was developed . Phase 2 is a fractionated extract of the white bean that has been clinically shown in 13 studies to delay the digestion and absorption of starch calories. Phase 2 neutralizes some of the digestive enzyme alpha amylase, temporarily delaying the digestion and absorption of carbohydrates, allowing a portion of them to pass through the system before they can be converted into glucose, and then fat. Phase 2 is considered generally recognized as safe by independent toxicologists and usually does not cause side effects. Phase 2 is available as an ingredient that can be formulated in a variety of nutritional supplements, foods and beverages. It is also sold as "StarchLite" in Europe.

Famous quotes containing the word background:
“Silence is the universal refuge, the sequel to all dull discourses and all foolish acts, a balm to our every chagrin, as welcome after satiety as after disappointment; that background which the painter may not daub, be he master or bungler, and which, however awkward a figure we may have made in the foreground, remains ever our inviolable asylum, where no indignity can assail, no personality can disturb us.”
—Henry David Thoreau (1817–1862)
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
“They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.”
—Jimmy Carter (James Earl Carter, Jr.)
