Does fiber decrease dietary fat absorption?

Question

Hello.

I'd like to know if taking my fish oil & vitamin E pills with a high-fiber food like oatmeal (5g dietary fiber: 3g soluble, 2 g insoluble) or metamucil (3 g dietary fiber: 2 g soluble) might be counterproductive.

Could anyone please comment on this? Will soluble or insoluble fiber decrease fat absorption, and *if*so is there a reference range of how much (and for how long) each type of fiber that would significantly interfere with fat absorption?

Thanks Sincerely.

Answer 1

it can if your fat intake is to low. 20% of cals from fats is the minimum.

a lot fat diet combined with too much fiber can decrease test production. you can not sustain a high level of lean body mass with low test levels.

Answer 2

Prevent Fat Absorption

Answer 3

Dan I don't believe you read the question at all he isn't trying to lose weight he is trying to absorb the healthy fats from his fish oil vitamins. I would go with Iv consultant's answer though it is a little hard to understand. Yes fiber does absorb some fats probably better to take the vitamins with a lower fiber meal. Although I've read pretty much everywhere that fiber does absorb some fat from the food we eat nowhere did I find how much or if it is even very significant.

Answer 4

Fiber can decrease fat absorption, which is beneficial for weight loss. Some fibers form a gel and can "absorb" the fat in the intestine, helping to prevent fat absorption and subsequent storage of adipose tissue. The stools of persons eating a high-fiber diet have a higher fat content than stools from someone eating low-fiber meals.


Soluble fiber. Found in dried beans and peas, oat bran, rice bran, barley, and fruit pectin (the substance used to thicken jams and jellies). Soluble fiber absorbs water in the intestines, mixes the food into a gel, and thereby slows the rate of glucose digestion and consequent absorption in the bloodstream.

Insoluble fiber. This is the stringy stuff that holds plants together. It's called "insoluble" because it doesn't dissolve in water. It can be found mainly in plant leaves, peels, skins, and the coverings of whole grains (e.g., wheat bran). Like a disposable diaper, insoluble fiber can absorb many times its own weight in water. This water adds bulk and softness to the stools and keeps them moving along more comfortably. Think of eating fiber like brushing your teeth - it cleans out your intestines daily.
