Ways to Reduce Food Waste
To reduce food waste, individuals can take the following steps:
- Utilise meal planning to buy only what is needed.
- Store food properly to prolong its shelf life.
- Compost food scraps to minimise landfill waste.
- Donate excess food to local charities or shelters.
- Repurpose leftovers into new meals.
The Most Wasted Foods
Food waste is a major contributor to climate change. The following are some of the most commonly wasted foods, and what can be done about it:
- Bread: A large portion of bread ends up in landfills contributing to greenhouse gas emissions. It can be repurposed into bread crumbs or used in recipes like bread and butter pudding.
- Fruit and vegetables: These account for a significant portion of food waste due to spoilage and overbuying. Leftover fruit and veg can be frozen for smoothies or used in soups.
- Dairy products: Milk, cheese, and yoghurt often go to waste. Extra milk can be turned into homemade cheese and yoghurt, while cheese rinds can add flavour to soups and stews.
- Meat and seafood: These are often discarded due to over-purchasing or improper storage. Leftover meat and seafood can be transformed into hearty stews or added to pasta dishes.
- Packaged foods: Pre-packaged meals and snacks also contribute to food waste. Unopened packaged foods can be donated to food banks or local charities.
- Canned goods: Excess canned goods from pantry cleanouts can still serve a purpose when donated, reducing waste while helping those in need.
The Role of Meat, Seafood, Dairy, and Plant-Based Diets
