How to eat ethically and sustainably on a budget

Food, glorious food! When it comes to what we eat, we’ve never had more choice.

5 ways to eat sustainably on a budget

Did you know there is no legal definition of ‘sustainable food’? That’s why you don’t find food labelled as such in your local supermarket, and it can be tricky to work out how to make the best food choices for sustainability. Here are the 5 easiest things you can do to make ethical choices while sticking to your budget.

  1. Eat what’s in season

Choosing seasonal vegetables and fruit is one of the best ways to eat healthy on a budget and a low-cost sustainable option. You’ll save money as seasonal produce is generally cheaper because you won’t have to shoulder the costs of food storage or transportation. Also, when a type of food comes into season and is more readily available, it's generally sold at lower prices to keep demand high.

  1. Plan meals to reduce food waste

It might surprise you that around a third of the food produced globally goes to waste. Or that the UK throws away 9.5 million tonnes of food waste in a single year. This waste emits a huge amount of greenhouse gases, so it’s better for the environment to buy only what you plan to use. Choose loose produce where possible, so you can avoid wasting money on food you’ll end up throwing out, and freeze anything you can’t eat while fresh.

If you fancy adding a little spontaneity to your life, why not sign up for the odd recipe box from Hello Fresh or Gousto? With perfectly portioned ingredients and step-by-step instructions, you could whip up a feast in the kitchen without a crumb going to waste.

  1. Shift to a plant-based diet

If you grew up with meat as the centre of your meals, it might be easier to cut it down rather than out. But bear in mind that the benefits of a plant-based diet are indisputable, from less inflammation in the body to a reduced carbon footprint.

Cutting down on meat is particularly impactful for climate change. The rearing of livestock generates 14% of global carbon emissions, similar to the amount generated by all forms of transport put together. Shifting to a plant-based diet is probably the single easiest way we can reduce our impact on the planet. And as research has found that plant-based meals cost around 40% less than meals featuring meat or fish, you’ll save good money too.

  1. Grow your own

Lucky enough to have a garden? Try your hand at growing your own produce to reduce your carbon footprint. Ok, we know what you’re thinking: is it really worth growing your own vegetables? Well, that depends. Some crops, such as potatoes and onions, are pretty cheap to buy in shops, so growing your own might not save you much money. But cherry tomatoes, courgettes, and runner beans can be prolific in a small space, while raspberries, strawberries, spinach and rocket are easy to grow and pricey to buy.

  1. Reduce your plastic

So simple and yet so effective. Bring a reusable bag when you shop rather than forking out for carrier bags and look for sustainable food packaging like paper over plastic. Why not cut even more plastic out of your kitchen with our free voucher codes for Bower Collective? This innovative zero-waste refill brand delivers pouches of household products like detergent and washing-up liquid for you to decant into reusable containers. You simply post your empties back in the pre-paid envelope provided. Plus, with our free voucher codes, you might score yourself a discount.


What is the cheapest sustainable food?

As well as seasonal fruit and vegetables, pulses are one of the cheapest sustainable foods in the UK. Lentils, beans, and chickpeas have a low carbon footprint and don't use excessive amounts of water to produce.

Pulses are a staple of any sustainable healthy eating diet, plus they're a cheap way to eat protein — helpful if you're cutting down on meat! Fancy getting creative with the magic beans in your kitchen? Turn to Jenny Chandler, the Queen of Beans, and her bestselling Pulse cookbook for enticing recipes galore.

A seasonal produce guide for the UK

Why is it better to eat seasonal food?

Locally-sourced, seasonal produce is fresher and has a much lower carbon footprint than food that’s shipped vast distances or stored for longer periods. When those crisp apples and juicy oranges ripen naturally and are harvested at just the right time, they’ll be richer in flavour and have a higher level of nutrients. That’s just science.

By choosing locally-sourced produce, you can also avoid the kind of pesticides that might come from countries with very relaxed laws about what can be sprayed on crops. Plus, eating with the seasons will give you a new appreciation for the planet — winter vegetables offer comfort and are made for hot stews and casseroles, while summer crops provide beta-carotene that protects us from sun damage along with delicious salad vegetables for lighter meals.

Chefs such as Nigel Slater and Hugh Fearnley-Whittingstall are avid advocates of seasonal eating - and for good reason too. Here's our guide to seasonal produce in the UK:

How do you source local produce?

Buying local takes a little more time and planning than grabbing whatever you fancy off of the supermarket shelf. Look for farm shops, farmer’s markets, local butchers, fishmongers, and cheesemongers.

If you’re trying to keep costs low, don’t expect to do a full food shop at these places, but you can use your visit to gather information and purchase the kind of ethical items it’s hard to find in supermarkets.

What questions should you ask at your local farmer’s market? Ask about sprays, pesticides and herbicides, animal welfare, and whether they have certifications like the Soil Association gold standard for organic and ethical produce.

When it comes to food choices and sustainability, the world of fish, meat and dairy can be tricky to navigate. Here’s what to look out for:

Meat and eggs

Only meat carrying the Pasture for Life logo has been 100% grass-fed. Otherwise, the animals may only have been partially grass-fed with unnatural feed like grain and cereal used to increase weight gain before slaughter.

The Soil Association is the UK’s oldest and largest organic certification organisation. And the presence of its logo also reflects the highest standards of animal welfare in the UK. Unlike RSPCA Assured, the Soil Association only accredits free-range producers, so animals have adequate access to the outdoors and actually see the light of the sun. This certification also means that animals are not treated with preventative antibiotics or fed GM food.

Fish

Can’t resist a fish dinner? Head straight to the Marine Conservation Society’s Good Fish Guide to discover everything you need to know about fish sustainability. Our oceans are becoming dangerously overfished with industrial vessels and unregulated fishing damaging our delicate ocean ecosystem. So, it's important to not only choose the right species but to choose ethically-sourced fish too.

Wild-caught Alaskan salmon, European hake, and farmed molluscs like clams, mussels, and oysters are some of the best sustainable seafood choices. While bluefin tuna, grouper, and Atlantic cod are just a few of the fish to throw back into the sea.

Milk

The BBC’s Science Focus suggests that all non-dairy milks are better for the environment than cow’s milk. So, perhaps it’s time to push dairy aside and find a suitable replacement for your coffee.

The award for plant-milk with the lowest greenhouse gas emissions goes to almond milk, although it does require the most water to produce. Soy is arguably the most eco-friendly plant-milk as it uses the least amount of water and only creates slightly higher emissions.

Why is it important to eat sustainably?

The issue of climate change can't be ignored. We need to do what we can to protect the planet and future generations. The way we have chosen to shop and eat has placed giant stress on the environment, contributing to climate change through deforestation, the use of pesticides, soil loss, overfishing, and more.

We need to act now and make the changes we can to avoid wasting natural resources and causing more damage to the planet. We can all make sustainable eating a part of our daily lives without it costing the earth.
