Reduced Lactose Whey

Whey is a co-product of cheese production. It is one of the components that separates from milk after <a href="http://en.wikipedia.org/wiki/Curdling" title="Curdling" >curdling</a>, when <a href="http://en.wikipedia.org/wiki/Rennet" title="Rennet" >rennet</a> or an edible acidic substance is added.

Because whey contains <a href="http://en.wikipedia.org/wiki/Lactose" title="Lactose" >lactose</a>, it should be avoided by those who are <a href="http://en.wikipedia.org/wiki/Lactose_intolerant" title="Lactose intolerant" class="mw-redirect" >lactose intolerant</a>. Dried whey, a very common food additive, contains more than 70% lactose.<a href="http://en.wikipedia.org/wiki/Whey#cite_note-Feedstuffs1983-4" >[5]</a> When used as a food additive, whey can contribute to quantities of lactose far above the level of tolerance of most lactose-intolerant individuals.

Liquid whey contains lactose, <a href="http://en.wikipedia.org/wiki/Vitamin" title="Vitamin" >vitamins</a>, <a href="http://en.wikipedia.org/wiki/Protein" title="Protein" >protein</a>, and <a href="http://en.wikipedia.org/wiki/Mineral" title="Mineral" >minerals</a>, along with traces of <a href="http://en.wikipedia.org/wiki/Fat" title="Fat" >fat</a>.

In 2005, researchers at <a href="http://en.wikipedia.org/wiki/Lund_University" title="Lund University" >Lund University</a> in <a href="http://en.wikipedia.org/wiki/Sweden" title="Sweden" >Sweden</a> discovered that whey appears to stimulate <a href="http://en.wikipedia.org/wiki/Insulin" title="Insulin" >insulin</a> release, in type 2 diabetics.<a href="http://en.wikipedia.org/wiki/Whey#cite_note-5" >[6]</a> Writing in the <a href="http://en.wikipedia.org/wiki/American_Journal_of_Clinical_Nutrition" title="American Journal of Clinical Nutrition" class="mw-redirect" >American Journal of Clinical Nutrition</a>, they also discovered that whey supplements can help regulate and reduce spikes in <a href="http://en.wikipedia.org/wiki/Blood_sugar" title="Blood sugar" >blood sugar</a> levels among people with <a href="http://en.wikipedia.org/wiki/Type_2_diabetes" title="Type 2 diabetes" class="mw-redirect" >type 2 diabetes</a> by increasing insulin secretion.
