Protein: Never Give It Up for the Following Reasons
There are many sources of protein, including meat, chicken, fish, eggs, and whey. Interest in protein has increased since the emergence of protein-based diets for weight loss.
Learn about the importance of protein, especially for women:
What is protein?
Human weight is made up of approximately 75 percent protein. It is found in almost every part of the body and tissue, including muscles, bones, skin, and hair. Amino acids are the building blocks of proteins.
There are two types of protein:
Complete proteins: These are animal proteins that contain all the essential amino acids needed to build new proteins.
Incomplete proteins: These are other protein sources that lack one or more essential amino acids that the body cannot produce. Examples include fruits, vegetables, grains, and nuts.
Protein and Disease Prevention
According to a study investigating the link between dietary protein and heart disease or stroke, women who consumed protein (about 110 grams daily) were 25 percent less likely to have a heart attack or die from heart disease than women who consumed less protein (about 68 grams daily) over a 14-year period.
It was not known whether the protein came from animals or plants, or whether it was part of a low-fat or high-fat diet. These results suggest that eating plenty of protein is not harmful to the heart.
Soy is a protein source that has received a lot of attention. Some research indicates that regularly eating soy-based foods may contribute to:
Reducing hot and cold flashes.
Reducing the risk of breast and prostate cancer.
Enhancing memory and cognitive abilities.
These effects may be due to the high concentrations of isoflavones in soy, a type of phytoestrogen.
Tip: Consume all types of protein from natural sources (food) to ensure you get all the amino acids you need.
