Proteins: a major challenge

INRA organised a debate on the issue of striking a balance between animal and plant proteins for sustainable diets.

Achieving sustainable diets is a major environmental and economic challenge the world over.

Steps are being taken at consumer and industrial levels to orient the food offer towards greater sustainability in terms of the environment and the preservation of resources, all the while guaranteeing good nutritional value. The European project LiveWell for Life resulted in eight recommendations to help develop healthy and sustainable diets.

In this context, the question of striking a balance between animal and plant protein is closely linked to the accessibility of good-quality protein for people, and diets with a small carbon footprint can contribute to reducing greenhouse gases. Meanwhile, the current global demand for protein is on the rise. That is why complementary sources of protein must be found, both for animals and for people. Forage and seed legumes have a particularly low environmental impact and are an excellent source of protein when combined with other nutrients; when coupled with grains and vegetables, they contribute to a balanced diet and also have agro-ecological benefits. Despite this, the production of forage and seed legumes in France and Europe remains limited because of stumbling blocks that must be overcome, both upstream and down.

In addition to plant sources, insects are a new avenue to be explored, for both animals and people. Here, social and cultural acceptability must be taken into account, as well as environmental, health, safety and regulatory constraints.

Métaprogramme DIDIT

Sur la base de l’expertise collective « Les comportements alimentaires – quels en sont les déterminants ? Quelles actions, pour quels effets ? », restituée à la DGAL en juin 2010, l’Inra a mis en place le métaprogramme DIDIT consacré aux déterminants des pratiques alimentaires et à leurs conséquences sur le bien-être et la santé.
