Nutritional guidelines face new scrutiny

An analysis by Anses, France’s food safety agency, questions whether nutritional recommendations may have unintended effects on mental health and eating behaviors, despite being based on solid scientific expertise aimed at preventing chronic diseases.

Focus of French health program

The National Nutrition and Health Program in France promotes messages such as eating more fruits and vegetables, limiting alcohol and red meat, and preferring whole grains. These guidelines aim to reduce the incidence of chronic diseases such as cardiovascular diseases, certain cancers, and type 2 diabetes.

Algorithm-driven food recommendations

Anses uses an algorithm to explore numerous combinations of foods, proposing adapted benchmarks by categories. These recommendations vary according to age and dietary preferences, such as plant-based diets, to ensure they are tailored and effective for different groups.

Unintended mental health effects

The analysis published on the Anses website, relayed by The Conversation, raises concerns that these recommendations, although nutritionally relevant, could lead to guilt, loss of self-confidence in relation to food, or even a real deregulation of eating behaviors when internalized as rigid and non-negotiable norms.

Individual responses vary

Not everyone reacts the same way to dietary recommendations, as individual perception filters influence how people think, feel, and organize their eating according to their history, sensitivity, and relationship with food. Adverse effects of cognitive control tend to intensify in unfavorable contexts, such as limited access to diverse food or budget constraints.

Balancing health and well-being

Anses suggests that while the guidelines remain valuable for public health, there is a need to consider the balance between prevention, pleasure, and psychological well-being. Finding the right balance between health messages and a peaceful relationship with food seems to be the real challenge for the years to come.
