For example, genes associated with traits that allowed early Europeans to produce vitamin D and digest milk into adulthood showed strong signs of selection, but only in the most recent time periods.

While light skin pigmentation likely aided early farmers in producing vitamin D in less sunny climates, the ability to digest animal milk enabled people to utilize milk as a nutrition source after dairy farming became common in Europe.

Now a new study from the University of Copenhagen and Bispebjerg Hospital suggests that a form of vitamin B3 may be the key to improving quality of life for these patients.

The patients either received a placebo or the vitamin B3 in doses of two grams a day.

In other words, the group treated with vitamin B3 experienced reduced lung inflammation during the study.
