As mentioned previously, recent findings suggest that a dietary intervention based on the Mediterranean diet (MD) could be useful to improve the mental health and overall quality of life of patients who have recovered from depression. The MD is a diet rich in plant-based foods, whose hallmark is the liberal consumption of olive oil, which represents its main culinary fat. A recent clinical trial carried out in Spain investigated the impact of a dietary intervention based on the MD on the quality of life of patients who had recovered from depression and found that the intervention resulted in significant improvements in the physical and mental quality of life of the participants, as well as reductions in anxiety and fatigue.
In the same vein, another study was carried out by researchers in Italy to determine the relation between adherence to the MD and various aspects of mental and physical health in older adults. They found that higher adherence to the MD was associated with better cognitive function and lower risk of depressive symptoms, and that the participants were more likely to have a better quality of life. The researchers also found that adherence to the MD was associated with successful aging, defined by a combination of physical, psychological, and social factors. These findings suggest that adherence to a MD may be an important factor in promoting successful aging and maintaining mental and physical health in older adults.
Finally, going further, Irish researchers investigated the effectiveness of a personalized nutrition approach based on individual metabolic characteristics, or “metabotypes”, in improving dietary quality and metabolic health. The study revealed that participants who received personalized nutrition advice based on their metabotype had greater improvements in dietary quality and metabolic health parameters compared to those who received standard dietary advice. Specifically, the personalized nutrition intervention resulted in greater improvements in body weight, blood pressure and blood lipid levels. These findings suggest that personalized nutrition approaches that take into account individual metabolic characteristics could be effective in promoting healthy eating habits and preventing chronic disease.
