Why is a gene check necessary for a healthy life?

Never before has the human race been able to access so much information about:

nutrition
health
sport and
relaxation

as today. At the same time, there have never before been so many people suffering from:

obesity
osteoporosis
heart disease
cancer

So-called adult-onset diabetes is now common, even among twenty-year-olds. The youngest diabetes patient in Germany is aged just five. The various forms of dementia, especially Alzheimer’s disease, are reaching epidemic levels.
The campaign to educate people has therefore not achieved much.
It is true that many people try to live a healthy life and that information about nutrition, health and sport is generally correct. However, only for a proportion of the population. Because people are genetically individual, it makes no sense for us all to live in a uniform manner. What is healthy for one may be really harmful for another. This applies in particular to diet. The attempt to promote one particular lifestyle as being healthy for all has ultimately been shown to be futile.
Instead, it is more important for the individual to know about his or her genetic predisposition. To accept that we are much more individual than we believed a few years ago. We have long believed that we may be different on the outside but not on the inside. Yet the impact made by our eating habits is different for each person.
