The Environment on a Platter

Transcription

1 We are what we eat, and what we eat affects both our health and the wellbeing of the planet. The Environment on a Platter In fact, food is one of the three main culprits in the pollution of the environment, together with housing and traffic. When determining the environmental impacts of various foods, the key factor is how the food is produced and processed, including cultivation, fertilizing, harvesting and preparation methods.

2 Carbon footprint kg The carbon footprint of food indicates how much greenhouse gas emissions are released into the atmosphere from the production, transport, preservation and processing of food. The carbon dioxide equivalent ( e) represents all the greenhouse gas emissions. Of all the domestic environmental factors, the food production chain is responsible for over 5 percent of the eutrophication of our water systems. It contributes well over half of the nitrogen and phosphorous runoff. The impact of 1 kg of phosphorous contamination in the water is expressed with the phosphorous equivalent ( e). This brochure describes the impacts of food on the environment, including carbon emissions and eutrophication. The effects are very similar for all foods, with the exception of fish. Fish caught in the wild reduce eutrophication while farmed fish have the opposite effect. The preparation of food plays a significant role in its environmental impact. For instance, the heating of ovens and stoves requires electricity. Cooking oatmeal on a stove accounts for almost two thirds of its entire environmental impact, while preparing it in a microwave reduces this impact considerably. When using an oven to prepare food, it is recommended to heat the oven only once and to use the resulting heat to make several dishes. Throwing away food is not only a burden on the environment, it is also a waste of energy and money. Before preparing meals, it is worthwhile to estimate as precisely as possible the amount of food that will be consumed. If anything is left over, you can use it the next day, take it to work as lunch or turn it into a new dish. The plate model provides guidance on eating in an environmentally-friendly manner. Foods can be divided roughly into two groups based on their environmental impact. Crops and vegetables grown on farmland have been shown to have the lowest carbon footprints and eutrophication impacts. In contrast, animal products and plants that require a lot of energy to grow have high impacts. Also the packaging and cold storage of food, requires a lot of energy. To best take the environment into account when choosing your meals, fill your plate with vegetables that are in season, and add only moderate amounts of dairy products, meat or fish. It is the meal as a whole that counts. Choose ingredients for your meals based on the current season. In the summer, opt for farm-grown vegetables, and in the wintertime, pick foods that can be stored without freezing, such as carrots, beets, cabbage, rutabagas and turnips. Complete your diet with berries, fruit and fish from the wild when they can be enjoyed fresh from nature. Plate model» In the model, half the plate is filled with vegetables, a fourth with meat, fish or legumes, and the remaining fourth with potatoes, pasta, rice or grains. A glass of milk or buttermilk, bread and a bread spread and a dessert also belong to this example meal.» The portion size has been calculated for women and teenage girls doing light work and engaging in moderate exercise. One portion corresponds to about 1/3 of your daily energy needs (around 65 ). Portions for primary school-aged children can be attained by reducing about 1 from the example meal, and portions for teenage boys and men by adding about 2.

Domestically grown potatoes and root vegetables have the lowest carbon dioxide emissions per kilogram, under.4 kg e/kg. Increasing the portion of fruits and vegetables in one s diet reduces its environmental impact and is also better for one s health. 1,61

In Finland, wheat is the most common grain grown for human consumption.» Almost all cereals are environmentally-friendly and have a carbon footprint of under 1 kg e/kg. Rice is the only exception, with various research placing its carbon footprint at anywhere from 2.5 to 6 kg e/kg. Rice can be replaced with domestic alternatives such as barley. Remember to select whole grains, when possible.

The size of the carbon footprint depends on the origin of the fish. Catching fish in the wild removes nutrients from the waters and reduces eutrophication. Wild fish also do not consume fish feed, so their environmental effects are much smaller than those of farmed fish.» Pike and Baltic herring, for example, are easy on the pocket and also environmentally-friendly. However, old and large specimens should be consumed in moderation since they may contain higher levels of dioxins or mercury.

One kilogram of rainbow trout has triple the eutrophication impact of one kilogram of beef, and quadruple that of one kilogram of pork. The environmental impact of rainbow trout has fallen by about a fifth over the last ten years. This is mostly the result of a more efficient use of feed.

This means that the easiest way to reduce environmental impacts is to limit the use of meat.» The production of beef has the largest carbon dioxide emissions, reaching as high as 2 kg e/kg in Finland. On the other hand, cattle grazes on grass that people cannot eat, and grass binds nutrients in the soil and prevents their runoff into the waters. Grazing can also preserve traditional landscapes.

Approximately 1 liters of milk are used to make one kilo of cheese, which increases cheese s carbon footprint by more than 1 kg e/kg. In other words, it is worth limiting the consumption of dairy products in your daily diet to milk, buttermilk, yogurt and similar products. Leave cheese aside for those special moments.

Their carbon footprint is about 1 kg e/kg. The environmental impact of olive oil is less than that of butter, which has a carbon footprint of about 4.8 kg e/kg. Since unsaturated fats are an essential part of a healthy diet, remember to include them in your meal plans. Sources of fats include not only oils and butter but also meat and fish.
