Because of the propaganda, you can be forgiven for thinking that cholesterol is a harmful alien substance that should be avoided at all costs. In fact, nothing could be further from the truth. Cholesterol is an essential component in the body. It is found in all the cells of the body, particularly in the brain and nerve cells. Body cells are continually dying and new ones being made. Cholesterol is a major building block from which cell walls are made. Cholesterol is also used to make a number of other important substances: hormones (including the sex hormones), bile acids and, in conjunction with sunlight on the skin, vitamin D 3 . The body uses large quantities of cholesterol every day and the substance is so important that, with the exception of brain cells, every body cell has the ability to make it.
It has also long been known that simple events, such as putting a cuff around the arm prior to taking a blood sample, or fear of the needle, can result in raised cholesterol values.
The idea that fibre could protect against heart attacks was hypothesised by Trowell in 1972, again based on research on rural Africans. The dietary intervention trials mentioned earlier, however, concluded that increasing dietary fibre had no beneficial effect on heart disease.
Fibre, by speeding food through the gut faster so that less nutrients are absorbed, inhibits the absorption of iron, calcium, phosphorus, magnesium, energy, proteins, fats and vitamins A, D, E and K. This happens with all types of fibre although with a normal Western-style, nutrient-rich diet, the loss caused by vegetable fibre intake is unimportant. More importantly, phytate found in cereal fibre (bran) also binds with calcium, iron and zinc making them indigestible, which in turn causes malabsorption. One study, for example, showed that subjects absorbed more iron from white bread than from wholemeal bread even though their intakes of iron were fifty percent higher with the wholemeal bread. Bran has also been shown to cause faecal losses of calcium, iron, zinc, phosphorus, nitrogen, fats, fatty acids and sterols, thus depleting the body of these materials
