The definition of sustainable development described in the Bruntland report states that it includes “meeting the needs of present generations without compromising the possibilities of future generations meeting their own needs”. In short, we must leave a legacy that makes the best use of our culture and traditions to envision a prosperous and comfortable future.
Food, what and how to eat, is a fundamental pillar for inculcating healthy and eco-friendly habits in future generations. As is logical and natural, during childhood and adolescence, the concept of life span is relative and not a priority in decision making.
It is more difficult to prioritize healthy foods in the eating habits of children and young people. It is therefore a good idea to rely on the protection of the environment as a first derivative: the image of a small polar bear on a piece of drifting ice as a symbol of climate change has a great power of conviction, and the relation to this Together with the fact our diet can be a determining driving force in the acquisition of new eating habits.
Fishing: Culture and Sustainability
Fish plays a major role in a balanced and healthy diet such as the Atlantic and Mediterranean diets.
Fishing is not only part of culture and tradition, but also a fundamental element of achieving food sovereignty.
Obviously, the environmental impact of how it is caught is directly affected, but, in general terms, fish and shellfish are the food groups with the best energy return rates in the form of proteins (the ratio between the energy that a food consumes). Provides us by the energy needed for it to reach the dining table) in relation to its carbon footprint.
Heck as a Megafood
Heck is one of our main allies in the task of incorporating fish into a balanced diet, as it combines a variety of key factors:
- Good taste and texture, a small number of bones and easy to clean, which make it an ideal fish to introduce children to the consumption of a healthy and sustainable diet.
- Culinary variety with a wide variety of recipes suitable even for kids.
- High nutritional content and health benefits. Its high protein content stands out, but it is also a moderate source of omega-3 acids (EPA, DPA and DHA) that have been described as important compounds in the development of the nervous system (especially in infants and children). Improvement in heart function.
- Low carbon footprint and minimum percentage in fishing gear such as the bottom long line (or hooked line) of the Galician and Spanish fleets.
The environmental impact of the heck caught with the long lines at the bottom
Hake caught along the bottom longline must have a maximum carbon footprint value of 10.82 kg CO₂ eq/kg and a Protein Energy Return Rate (TREprot) greater than 1.4%, to be considered sustainable according to ecological requirements.
A 2021 study conducted with 26 vessels integrated into the Port of Burella and the Burella Shipowners Association’s association of fishing producers indicates that the bottom long line hack is in Gartner’s magic quadrant, both of the variables analyzed. (carbon footprint and energy return). Rate).
At the Researchers Night held in Santiago de Compostela in 2021, a memo-game based on the environmental impact of the 63 most consumed foods in Spain was presented, in which a large number of primary school students actively participated. The original intention was to convey the message: “What is good for you is also good for the planet”.
The memo-game consisted of 63 cards with specific food items found in shopping carts where it was identified as:
- nutrition: On the face of the card, placing the foods in different groups of the food pyramid.
- carbon and water footprintConversely, highlighting the contribution of each to climate change (Sustainable Development Goal 13) and water management (SDG 6).
The children had to choose the foods of their choice, and then examine the environmental impact on them. Next, he put the number obtained on a ruler where it was compared to the number of kilometers covered by the car. Quickly, they sought to optimize selection within each of the pyramid’s food groups to reduce their environmental footprint. In the end, it was seen that the fish, led by Heck, placed in the race of their final choice.
Let’s take advantage of little ones’ vacations to slowly incorporate healthy and sustainable eating habits. This will be our best legacy for their future and the planet where they develop their lives. We have only one earth at the moment.
