What assisted living can learn from long-term care: Use of egg-derived emulsifiers is not recommended for people with an egg allergy due to the risk of reaction. In situations where there is no suitable emulsifying agent for a person at risk of developing essential fatty acid deficiency, cooking oils may be spread upon large portions of available skin for supplementation by transdermal absorption.
Another type of fat emulsion Omegaven is being used experimentally within the US primarily in the pediatric population. It is made of fish oil instead of the egg based formulas more widely in use. Research has shown use of Omegaven may reverse and prevent liver disease and cholestasis. Developed in the s by Dr. Dudrick, who as a surgical resident in the University of Pennsylvania, working in the basic science laboratory of Dr.
Jonathan Rhoads, was the first to successfully nourish initially Beagle puppies and subsequently newborn babies with catastrophic gastrointestinal malignancies.

Fiber effectively lowers blood cholesterol levels. It appears that soluble fiber binds to cholesterol and moves it down the digestive tract so that it can be excreted from the body.
This prevents the cholesterol from being reabsorbed into the bloodstream. A high-fiber diet is the preferred nondrug treatment for constipation. Fiber in the diet adds more bulk to the stools, making them softer and shortening the time foods stay in the digestive tract. Fiber in the diet adds more bulk and softens the stool, thus, reducing painful hemorrhoidal symptoms.
Soluble fiber in the diet slows down the rise of blood sugar levels following a meal and helps control diabetes. Dietary fiber makes a person feel full faster. Insoluble fiber in the diet speeds up the movement of the stools through the gastrointestinal tract. The faster food travels through the digestive tract, the less time there is for potential cancer-causing substances to work.
Therefore, diets high in insoluble fiber help prevent the accumulation of toxic substances that cause cancer of the colon. Because fiber reduces fat absorption in the digestive tract, it also may prevent breast cancer. A diet low in fat also promotes good health and prevents many diseases.
