Does genetic predisposition to lactase persistence influence dietary choices beyond dairy?

This discussion will explore genetic predispositions to lactase persistance and their potential impact on dietary decisions beyond dairy. It's important to me as a nutritionist and dietitian that I understand the many factors which can influence our food choices, including genetics. This analysis provides insight into our complex dietary decisions and offers practical advice to those who are influenced by lactase persistency status.

Understand Your Genetic Predisposition

It is vital to understand your genetic predisposition towards lactase persistance as this can have a variety of effects on your diet. Genetics determines lactase persistency, which is the ability to consume dairy products. Lactase inconsistency can cause digestive problems for some people. It could lead to them avoiding dairy products, which can have negative effects on their nutritional intake.

In a study published in The American Journal of Clinical Nutrition, it was found that those with non-persistence of lactase were more likely than others to consume less dairy products and therefore have lowered calcium intake. It is important to know your lactase status. You'll need to supplement your calcium intake if you are lactase intolerant.

What to Do: How to Recognize the Effect of Lactase Resistance

It's important to know whether or not you are lactase-persistent in order to understand the impact on your diet. You can do this by genetic testing, or monitoring the reaction of your body to foods high in lactose. You can then adjust your diet based on your diagnosis.

Even if your lactase persistence is high, you can still have your diet influenced by environmental, cultural and personal factors. Lactase persistency is only one part of the puzzle when it comes to forming our eating habits.

More Tips and Suggestions

It's important to keep a varied and balanced diet, in addition to modifying your food intake to match your lactase status. It is important to include a variety of foods in your diet. This will help you get all the nutrients that your body requires. Exercise, hydration and stress management all play a role in overall health.


Understanding your genetic predisposition towards lactase persistency can influence the choices you make in terms of food, even if they are not dairy. It is possible to maintain an overall healthy diet, regardless of whether you have lactase persistency. When it comes to making informed decisions about your diet, you need knowledge.
