They need to be mindful of getting enough vitamin D from other fortified foods like certain brands of orange juice, or to consider trying lactose-free dairy products.鈥</p> <p>The researchers also confirmed previous findings that those who have the gene for lactose intolerance are slightly shorter than those who don鈥檛 鈥 suggesting insufficient intakes of these essential nutrients are limiting bone growth.</p> <p>And&nbsp;for the first time, they found that people with just one 鈥&nbsp;instead of two&nbsp;copies 鈥&nbsp;of this variant were also affected by lactose intolerance,&nbsp;albeit to a lesser degree, suggesting that clinical definitions and genetic classifications of lactose intolerance could be expanded.&nbsp;</p> <p>Lactose intolerance was found across ethnic groups 鈥 although the largest proportion by far occurred in people of East Asian heritage.&nbsp;</p> <p>The study&nbsp;of 1,495 Canadian men and women from different ethnicities&nbsp;will be published in the June 2017 issue of the <em>Journal of Nutrition</em>. <a href="http://jn.nutrition.org/content/early/2017/04/26/jn.116.246108.full.pdf+html?sid=7badc5a8-f952-4230-8982-1a918d1826c8">It is available now online</a>.</p> <p>&nbsp;</p> </div> <div class="field field--name-field-news-home-page-banner field--type-boolean field--label-above"> <div class="field__label">News home page banner</div> <div class="field__item">Off</div> </div> Fri, 12 May 2017 16:40:02 +0000 ullahnor 107507 at
