For sustainable eating according to one sustainable diet there are ten rules. Local products, tap water, organic products and the others that we see below. Why sustainable diet it is the one that is good for our life but also for the environment according to the definition of sustainable diet developed by FAO: low environmental impact food regime that contributes to food and nutritional security, but also to a healthy life for present and future generations.
The 10 rules of the sustainable diet
- Buy local products. Even if not everything we eat can be found in the area, the benefits of zero km are undeniable. Long live the fresh products that support the local economy and contain CO2 emissions by reducing transport.
- Eat seasonal products. Well yes, sometimes we forget it but fruit and vegetables have their own seasonality. A diet that follows the seasons is healthier, tastier and reduces costs for the environment.
- Limit your consumption of meat. The sustainable diet is close to the Mediterranean diet and excludes a menu with a prevalence of animal proteins (which, among other things, costs more). Meat should be consumed in moderate quantities a few times a week, preferring that produced with traditional (non-intensive) and organic zootechnics.
- Choose the fish well. Apart from respecting the minimum size rule, local species should be preferred even if they are not the most valued on the market. To the classic 'fish steak' species (tuna, sea bass, salmon ...) you can prefer blue fish or in any case diversify your choice.
- Avoid food waste. It is not sustainable that almost a third of the food purchased ends up in the dustbin. This enormous waste involves a huge environmental impact, in addition to the economic loss.
- Give preference to organic products. Italy excels in organic matters in terms of cultivated areas, but in the consumption of organic products it could do better. Organic farming is to be preferred because it is based on respect for nature, resources (soil and water) and protects biodiversity by eliminating the use of chemicals extraneous to natural processes.
- Reduce packaging. It makes no sense that around a few grams of food there is a bulky package of paper, cardboard, plastic and metal. Packaging is transformed into waste and therefore into a social cost. Goods with less packaging should be preferred.
- Avoid overly processed foods. Some argue that the right rule is that of 5 and say: 'avoid products that contain more than 5 ingredients!'. One wonders 'why not 4' or 'why not 6', but that's not the point. Certainly over-processed foods require many resources to be produced and have a high environmental impact. They also usually contain too many sugars, salts and fats.
- Drink tap water. It is guaranteed healthy and often good too. Bottled water may not necessarily be better than tap water and if we protect the water tables we can have excellent water at home. There are many systems for purifying domestic water.
- Avoid waste in the stove. It could be a sequel to rule number 5, but it deserves a separate emphasis: in addition to not wasting and recycling food, good use of the stove helps not to waste resources and money.
