peptides

Clippings of papers

study/analysis that found that the pepsin hydrosylated of wheat gluten and casein contain peptides with opioid activity. 

a chart or drawing illustrates the substances that affect energy intake and expenditure, and opioids are included in that drawing (they could be endogenous or exogenous).

Digestive enzymes break down proteins into these long chains of amino acids. Incomplete digestion of protein leaves short chains of amino acids referred to as peptides. 

some peptides can pass from the intestines into the blood stream where they may set up an immune reaction because they are considered foreign substances.

dairy products and grain have been associated with adverse reactions not all of which involve allergen-specific immune response as measured by typical diagnostic techniques 

Some of the peptides associated with digestion of dietary proteins (e.g., milk, wheat) are in the opioid family 

Opioids alter behavior because of their ability to bind to endorphin and enkephalin receptors in the brain. Endorphins and enkephalins are endogenous opioid-peptide neurotransmitters found in various parts of the brain and also produced by the pituitary gland. They are involved in the reduction of pain as well as in pleasure and reward

Exorphins, such as opioids generated from digestion, attach to the same receptors as the endogenous opioids and can inhibit the breakdown of endogenous peptides and change the level of endogenous opioids


FT - so wheat and dairy products are potentially addicting... one more paper saying this.
