Fiber has almost no food value for humans because our guts cannot break down the fiber cell walls. But some foods which have a lot of fiber also contain useful vitamins and minerals (eg. fruit and vegetables). Fiber passes through the human gut almost untouched.

Alcohol gets into the blood faster than anything else we eat or drink. The blood carries it to the liver where some of it is broken down. If there is too much for the liver to cope with at once it stays in the blood. When the blood reaches the brain the alcohol very easily passes into the brain cells. This causes the typical mood changes that occur after drinking alcohol. But smelling alcohol will not affect you. Too much alcohol over too long a time can damage your liver. But this is not the only harm it can cause.

Arteries carry the blood away from the heart and out to all parts of the body. It is returned to the heart along the veins. Sometimes – for reasons that are not yet fully understood – fat-like particles carried in the blood are deposited on the inside of an artery wall and make the passage narrower. Eventually it may become so narrow that blood cannot pass through. The part of the body supplied by that artery is then starved of vital oxygen carried by the blood. If this happens in the coronary arteries the heart’s own blood supply) part of the heart muscle dies.
