For example, ensuring that you're eating minimally processed foods, reducing plastic packaging, eating locally, seasonally and some may argue most importantly, reducing your food waste are all ways to reduce your environmental impact.
For example, if you're reducing your meat intake but getting to the end of the week and throwing loads of wilted vegetables away, then reducing your food waste might be an area to work on (learn ways to reduce food waste here). Or perhaps you feel your diet already has a relatively low environmental impact but is not nutritionally adequate. Then including more foods from each of the food groups might be the area you need to focus on.
If you've decided to reduce your meat intake but are not replacing this meat with plant-based sources of protein and iron, then this may be the most important next step. Regardless of what area you choose to improve next, we know that every little step towards maintaining a healthy and sustainable diet will make an impact on your health and the environment, so choose an area to work on and take the next step!
