SCIENTIFIC THINKING Another aspect of the Nurses’ Health Study introduced in Module 3.9 looked at the percentage of change in the risk of coronary heart disease associated with substituting one dietary component for another. These results estimated that replacement of 5% of energy from saturated fat in the diet with unsaturated fats would reduce the risk of heart disease by 42%, and that the replacement of 2% of energy from trans fat with unsaturated fats would reduce the risk by 53%. Explain what these numbers mean.

For instance, some promoters of weight-loss diets claim that carbohydrate (for example, rice) is harmful and should be omitted from the diet or intake of carbohydrate significantly reduced. There is a saying that “fats burn in the fire of carbohydrates”. What is the meaning of this? What would be the effect of a significant reduction in carbohydrate intake on the utilization of fats for energy? Cite the biochemical mechanisms that support your answer.
