Gastric Emptying, Whey vs Casein

http://www.slideshare.net/martinfried/delayed-stomach-emptying-study

This study shows that whey empties faster than casein. There are many implications to this in everyday life, in all age groups and in all conditions. Ask me about them.

For example, if your newborn baby spits up alot, a whey formula empties from the stomach faster, and improves emptying- thus reducing the number of episodes of reflux. Cow’s milk is 80% curds or casein, and 20% whey. When the make cheese from milk and they stir it until the curds precipitate. They keep the curds and empty out the whey. Most cheeses are 100% casein. This would be a bad choice of food to eat right before laying down to go to bed, knowing that it will take over three hours to empty from your stomach—–and perhaps contribute to nighttime reflux. Milk doesnt contain gluten- as is acceptable as part of a celiac or gluten free diet. Most cows milk is fortified with Vitamin A and D, but is low in iron and should not be used in infants under a year of age.

Curds verses Whey- When is Whey an advantage to take?

Video

 

THis video shows that whey protein which remains a liquid in the stomach, empties faster than curds which become solid in the stomach. Whey emptying is faster and more useful in people with stomach problems that delay gastric emptying. Whey actually restored the emptying of the stomach to normal for a liquid. ( 50% emptied in one hour, and 75% emptied at two hours)
