머리 의 R&D at Fazer Mills, Markku Mikola (Ph.D. Food Science) has worked with oats for over 30 years, first as a researcher and later in oat commercialization. Mikola explains how oat beta glucan became such a hot topic, key health benefits of oat beta glucan – and busts a few myths.
"It's hard to pinpoint exactly when the hype around oat ‑glucan health benefits began, but in 1987 a medical journalist named Robert Kowalski wrote a best-selling book called the {{}}Week Cholesterol Cure, in which he made sever health claims about oats. This sparked a great deal of interest in researchers and health-minded consumers alike," Mikola describes.
"Fast forward ten years and in in 1997, the US Food and Drug Administration FDA approved the first health claims relating to oats," he adds.
The FDA 규정된 that in the US companies could claim that eating foods made from rolled oats, 귀리 밀기울, and 귀리 밀가루 may 감소시키다 the 위험 of 관상동맥 심장 질병[vii] – 제공 그것 the 귀리 포함 충분히 용해성 섬유, 및 그들 있다 소비된 as a 부분 of a 저지방 다이어트.
"In Europe, health claims relating to oat ‑glucan first gained official status in 2009, when the European Food Safety Authority, EFSA, stated that regular consumption of this soluble fiber contributes to the maintenance of normal blood cholesterol levels," Mikola remarks.
"A 년 나중에, in 2010, the EFSA acknowledged that 소비 3 그램 of 귀리 ‑글루칸 매일 감소 the 콜레스테롤 수준 in the blood," Mikola 계속. At the same time, the EFSA 또한 승인 another health claim about 귀리 베타 글루칸: that 그것 느려지는 아래로 the 상승 의 혈액 설탕 수준 after a 식사.
"The 정확한 EFSA 건강 청구 is that the 소비 of ‑글루칸 from 귀리 as part of a meal 기여 to the 감소 of the 혈액 포도당 상승 after that 식사 – if the food contains at least 4 grams of ‑glucan from oats for each 30 grams of available carbohydrates," Mikola recites.
어떻게 귀리 베타 글루칸 감소 콜레스테롤?
All in all, the EFSA has approved four health claims relating to 귀리 or 귀리 beta glucan[ix]. Mikola reminds that health claims on food products are an effective way to communicate the link between a food and a specific health benefit and thus help consumers choose healthy diets.
"높음 콜레스테롤 is a 위험 요인 in the 발달 의 관상동맥 심장 질병, so 추가 귀리 ‑글루칸 to 당신의 다이어트 is 확실히 something I would advise doing," Mikola affirms.
하지만 어떻게 정확히 귀리 베타 글루칸 도움 감소 콜레스테롤? 미콜라 밑줄 that while the 정확 메커니즘 is unknown, the 넓게 받아들여지는 설명 사이 연구원 is 공정하게 simple:
언제 소화, 귀리 베타 글루칸 용해 및 생성 a 높이 점성, 껌 같은 젤 in the 내장. the 젤 감소시키다 the 흡수 의 콜레스테롤이 풍부한 담즙 산 및 식이 콜레스테롤, 배설물. 이 안에 회전 촉진 생산 의 새로운 담즙 산, which 감소시키는 the 콜레스테롤 in the 혈액.
"To put it a bit crudely in layman's terms, when you consume enough oat ‑glucan, you eventually flush a portion of your cholesterol down the sewer," he clarifies.
