Our DNA makes us different: we have different eye colour, different skin, talents, we are differently susceptible to illnesses, and we have completely unique nutritional needs.
The unique needs of every individual are the subject of a new branch of nutrigenomics – personalised nutrition. A personalised nutritional approach is essential and absolutely necessary for an optimal diet, in the same way as your personal physician, who knows you, is necessary for ensuring your health.
An average person should eat at least 30 g of fibre/day, and cover 45-60 % of their daily energy needs with carbohydrates. The daily intake of fats should be between 25-30 %, and the intake of saturated fats should represent only 1/3 of it. An average active adult should ingest 0.8 g/kg body mass of proteins, or 10-15 % of daily calorie needs.
Scientific studies have shown that genetic variants have a great influence on our metabolism making the optimal nutritional needs very specific for each individual. Therefore, for achieving perfect well-being and health, the recommended daily intake of carbohydrates, saturated fats, unsaturated fats, and proteins should be adjusted in accordance to your genetic make-up.
Saturated fats are found mostly in food of animal origin. Our body uses them as a source of energy, but, unfortunately, in connection to genetic makeup, they also have the property of increasing the risk of becoming overweight. Through a 20 year-long study scientists have discovered a gene that causes some people gain weight quicker due to saturated fats than others. They discovered that saturated fats have an even more negative effect on people with an unfavourable variant of the gene APOA2. In case of excessive consumption of saturated fats, their risk of becoming overweight is twice as high, compared to carriers of the common variant of the gene.
Polyunsaturated fats are essential for our body – our body desperately needs to get them from food, as it cannot produce them. They are vital for a healthy heart and brain function, as well as our growth and development. Even though unsaturated fats are very beneficial for our body, they have an even more positive effect for some people. In the research study on which our analysis is
