Dietary Fats and Substitutes (IV)
Types of fat-reducing ingredients
The fat substitutes were designed to duplicate the taste and texture of fat, and usually fall into three categories based on carbohydrates, protein-based or based on fat. To begin with, many of the products with lower fat content offered on the market were the result of new processing techniques that made use of common ingredients such as water, gums and sugars.
Other fat substitutes are extracted from the protein or fat itself. Each type of fat substitute ingredient provides some or all functions of the original fat, for example, moisture in baked goods. The ingredients used to replace fats depends on how food is prepared for consumption. For example, not all fat substitutes ingredients are stable against heat. Therefore, the type of substitute that is used in a salad dressing can not be used in a mixture for preparing baked masses.Calories are still important and common sense
Many nutritionists explain that low-fat foods may be effective to help reduce the fat in our diet when used to replace foods high in fat. As with all food choices, it is important that consumers recognize that the calories and portion size are still important even if you consume foods with lower fat content.
The specific question for researchers is whether consumers compensate or overcompensate the calories or fat when fed exclusively from nutrient-modified foods. In general, research indicates that those who are able to regulate their calorie intake on a regular basis, continue to do so even if you only eat foods low in fat. The result: the same amount of total calories with a lower percentage from fat. By contrast, those who only care about body weight, tend to reduce calorie intake of foods using fat modified.
As more studies are done in the short and long term in the various communities will bring a better understanding of the impact of foods with modified fat content on fat and calories. There is evidence that the availability of nutrients options modified foods is of great help to achieve compliance in the long-term weight maintenance programs.
Health professionals can play a key role in helping consumers understand how to take advantage of lower fat foods to meet dietary recommendations of fat in a well balanced diet that incorporates the recommended amounts of different types food. To help manage the intake of fat and calories, consumers could obtain more benefit to low-fat food choices to replace other foods with more fat, and not to incorporate into the diet.
Despite the continued consumer demand for lower fat foods, common sense will always play an important role in a healthy diet. Enjoy low-fat version of their favorite food is a good way to reduce fat intake, and may contribute to a healthy lifestyle that can be enjoyed.
