Miracle diets can produce health issues due to rapid weight loss, excessive energy restrictions, and the exclusion of certain foods or nutrients from the diet.
Foods that are rich in fats and sugars are pleasurable because they stimulate our reward circuits, the same circuits that are activated by drugs. In a context in which unhealthy diets and drug abuse are common from adolescence, it is important to investigate their consequences.
For guidelines to be useful, they must consider cultural, anthropological, educational, social, and economic factors, as well as the usual diet of the target society.
There is a widespread misconception, mainly due to perverse agnogenic practices, that nutrition is hard and confusing, that we do not really know what to eat and that health professionals cannot agree.
Nutritional epidemiology currently studies the diet-disease relationships. In this review, we analyse the impact of diet on health and the importance of dietary factors in the prevention of non-communicable diseases.
Growing concern for health has fuelled interest in the relationship between diet and disease prevention. But despite the remarkable scientific advances, there are still many unanswered questions, and many evidence-based messages do not reach the population and are lost in a sea of misinformation and half-truths.
The monograph, coordinated by José Pío Beltrán, CSIC research professor at the Institute for Plant Molecular and Cellular Biology (CSIC-UPV), analyses biotechnological advances in plant production.
These are just a few examples of how an increase in the generation of energy and food, per se, might not address the needs of the population which is in fact still growing.
We now have more information than ever about nutrition. But, at the same time, we have great difficulties to identify reliable information and, above all, to understand the limitations of science to answer so many of the questions that we make ourselves about how the food we eat and the food we avoid affects our health.
