Nutrition influences wellbeing and health. This is common knowledge. Tolerance of foods and need for particular nutrients, however, differ between individuals. Genetic variants account for some of these inter-individual differences. For example, a variant of the gene involved in lactose metabolism is a common cause of lactose intolerance; genetic factors predispose to gluten sensitivity; and uptake of iron is increased in genetically predisposed people resulting in a wealth of signs and symptoms that range from nausea to liver damage.
PGS box nutrition investigates genetic variants that contribute to symptoms caused by unsuitable nutrition. Therefore this box is useful to persons who encounter ambiguous, recurring symptoms after eating. Furthermore, testing is also sensible if close relatives suffer from food intolerance. The detection of relevant variants facilitates adjustment of nutrition thus improving health and wellbeing.
