• protein quality

    Some proteins are absorbed extremely well, an example would be egg albumin, which is a protein found in the white of an egg rather than the yolk. The egg white protein has an extremely high biological availability and all of the essential amino acids in the right balance. Gelatin though has many of the essential amino acids however does not have an amino acid called tryptophan and because it is lacking – it isn’t considered a complete form of protein. If it is combined with other sources of protein it is okay. The bottom line is if you are looking at carbohydrates, fat or protein, it is important to look at the composition of them. You can read the declarations of the food labels. Often snack foods will contain inefficient protein, or protein that does not contain all
    the essential amino acids. It is important to know that all carbohydrates, fat and proteins are made up of these building blocks and it is important to know to have a balance of all of these building blocks for good health.

     
  • Functional foods

    It is a term that gets bantered about by people who are food scientists or food companies that are talking about different kinds of foods. Usually when they are talking about a functional food it is a food analog, which is a food that has been put together by a food manufacturer. It might also be called a nutraceutical. Functional foods can also be natural foods which have been found to be beneficial for a specific purpose. Some companies manufacture internal tube feeding formulas for hospital use. The composition of the product contains all the nutrition in the right proportions for protein and amino acids plus fat with the right fatty acids and the right vitamins and minerals and you put all that together and it has a particular food functionality. There are foods that are designed to resolve particular health problems. Let’s take something common like lactose intolerance, people have trouble digesting the lactose because they are missing an enzyme called lactaid. So an example of a functional food would be a food that was put together without any milk protein or lactose sugar. It functions with that person who is lactose intolerant. You can take that example and apply it to anyone else who has special feeding needs.
