Substitutes of different ingredients:
There is a need to find a low energy food substitute that is acceptable for some ingredient of a high energy food. This is needed for converting a food into its diet version. This can be done simply, by making a replacement in some of the sugar ingredients of the food with any type of substitute for sugar. For example, there is Coke Diet as a substitute of regular Coke. In some other food materials like snacks and stuff, they are baked instead of being fried. This reduces the energy of the food. There are other cases as well when the high calorie ingredients are replace with low fat ingredients. Different companies use such ways for making diet foods and thus make the diet meals delivered.
In foods containing whole grains, the content that is high in fiber is supposed to be displacing some of the component of the starch of the flour. As there are some fibers that do not have any sort of energy, the result is a reduction in energy modestly. There is another technique as well, that depends upon the addition that is done intentionally of other ingredients of reduced energy food, like a starch or fiber that is resistant or dietary respectively, for replacing part of the flour and achieving a reduced energy more significantly.
Controversies and reality:
In the foods for diet, in which sugar is replaced with low energy substitutes of food, some controversy is seen which is based on the possibility of the fact that the substitutes of sugar that are used for replacing sugar are themselves supposed to be harmful. The sweeteners that are created artificially have been a source of high scrutiny for a lot of recent years. But, according to NCI (National Cancer Institute) and other agencies known for healthcare, there is no strong scientific proof that any of the sweeteners prepared artificially that are approved to be used are a source of causing cancer or any other health issues that are considered to be serious.
