Lactose intolerance is a kind of chronic illness often seen among a vast range of people. It may be considered as a common issue in humans. But it can cause some serious deficiencies in terms of a major nutrient. The latest study evolved by a group of scientists from the University of Toronto hinted that humans who are genetically intolerant to lactose have a lower level of Vitamin D in their blood. The researchers also suggested that the those of lactose intolerants must consume foods and fruits having a greater level of Vitamin D to stabilize the deficiency in their blood.
According to Medical News Today, lactose intolerance in human majorly arises due to a special gene segment. This kind of gene, often found in ethnic groups, makes those humans unable to digest lactose, an essential sugar content found in dairy products, such as milk, butter, cheese etc. The study suggested that the people intolerant to lactose have a very rare chance of consumption of dairy products on a regular basis. And thus they also hold very low levels of Vitamin D, as dairy products are filled with the major nutrient. And therefore, they should always opt for other similar non-dairy food contents, possibly fruits and juices.
Besides of the Vitamin D deficiency, there are other side effects of lactose intolerance as well. MedicalXpress pointed that those, who suffer from lactose intolerance due to the presence of one or more certain genes in their body, are also shorter than the rest. A slight or major difference in height seems in the cases as the limited existence of Vitamin D also affects bone growth.
Ahmed El-Sohemy, a professor of nutrition at the Faculty of Medicine at the University of Toronto, who also co-authored the study rightly said:"These findings speak to the need for greater awareness for those who limit dairy because of lactose intolerance. 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."
The study was published in the Journal of Nutrition recently. It also fetched new ways to combat against the featured sort of mall nutrition caused by Vitamin D deficiency.
