You may resolve to go vegan – analysis reveals chopping out meat and dairy is without doubt one of the finest methods to cut back your affect on the planet; flexitarian – a ‘informal vegetarian’ weight-reduction plan; or plant-based – any weight-reduction plan that target consuming meals from plant sources. All of them sound nice in principle, however what does that truly appear to be in your plate? What meals do you have to be consuming if you wish to comply with a sustainable weight-reduction plan?
We’ve discovered the ten most sustainable meals everybody ought to eat, and the worst meals on the earth from an environmental perspective.
What’s a sustainable meals?
Good query. The WHO says sustainable diets ‘promote all dimensions of people’ well being and wellbeing [and] have low environmental strain and affect’. In different phrases, they preserve you and the planet wholesome. This implies you’ll have to put some thought into how your meals is produced and the place it comes from; we all know not all vegan meals is environmentally pleasant.
Basically, a sustainable meals ought to have a low carbon footprint, and never contribute to deforestation, water shortage, overfishing or lack of biodiversity. It also needs to offer you sufficient vitamins to dwell a wholesome, joyful life – not simply cease you from getting unwell. It sounds loads to ask, however there quite a lot of meals that match the invoice.
1. Pulses
Pulses embrace lentils, chickpeas, peas and beans: these tiny crops are dietary powerhouses. The UN says they’re full of protein, low in fats, wealthy in soluble fibre and have been discovered to assist cut back your danger of power ailments reminiscent of diabetes, weight problems and coronary heart illness.
Pulses even have an unbelievable skill to ‘self-fertilise’ the soil; their roots include micro organism that convert nitrogen within the air into a distinct type that can be utilized by crops, decreasing the necessity for synthetic fertilisers. Plus, pulses use much less land to supply extra protein – it takes practically 100 occasions extra land to supply a gram of protein from lamb or beef versus peas or tofu.
2. Leafy greens
The WWF calls darkish leafy greens reminiscent of spinach, kale, watercress and broccoli ‘probably the most versatile and nutritious of all kinds of greens’. They’ve been proven to assist decrease your danger of coronary heart illness and diabetes, and are wealthy in antioxidants and anti inflammatory compounds.
What’s extra, they’re a really planet-friendly meals. They’re quick rising (so farmers can get multiple harvest a yr) and have very low carbon emissions throughout their rising and harvesting processes. However be sure to do eat them – the UK throws away 178 million luggage of salad yearly, and meals waste is without doubt one of the greatest contributors to greenhouse gases.
3. Mushrooms
The common-or-garden mushroom was really thought-about ‘the meals of the Gods’ by the Romans! Fungi are wealthy in quite a lot of vitamins reminiscent of B nutritional vitamins and particularly vitamin D, which we usually make through the solar’s rays on our pores and skin. Their style and texture make them superb meat substitutes, or for bulking out meat dishes.
The American Mushroom Institute says a kilogram of mushrooms produces lower than 0.7kg of CO2, whereas different (mushroom-sponsored) research discovered they want much less water and fewer vitality than most different agricultural crops. There are some issues that mushrooms themselves launch massive quantities of CO2, however researchers say we may pipe that carbon again into greenhouses to develop different crops.
4. Regionally grown fruits
This might sound apparent – the additional a meals has to journey, the larger its carbon footprint – however the stats are so surprising, it bears repeating. Solely 7% of the fruits we eat within the UK are grown right here; the remaining are imported, with 70% from outdoors Europe.
The water footprint (WF) of imported fruits is large in contrast with home-grown – raspberries’ WF is 53 occasions larger and plums’ 45 occasions. Imported apples, pears and strawberries have a WF 6-10 occasions increased than these grown on UK soil. One reply is to solely eat what’s in season – and freeze recent fruit in summer time – whereas scientists additionally counsel constructing extra UK ripening services to cut back the affect of refrigerated transport. Till then, get to know your Pippins out of your Pig’s Snout.
5. Seaweed
Seaweed is rising in popularity – not simply as an ingredient in dishes like sushi or laverbread, however seaweed extracts reminiscent of agar can be utilized as vegan alternate options to gelatine. The well being advantages differ relying on the kind of seaweed however normally, seaweed is wealthy in protein and omega-3 fatty acids, vitamin C, antioxidants and iodine.
It has planet well being advantages, too. Algae, together with seaweed, produces round 50% of all of the oxygen on earth, it might take up carbon dioxide, nitrogen and phosphate within the sea – changing agricultural run-off – and may be harvested a number of occasions a yr, offering another earnings for coastal communities to keep away from over-fishing.
6. Mussels
Staying below the ocean, mussels and different bivalves like clams must be in your sustainable menu. They include extra protein than many meat and plant crops, and have excessive ranges of omega-3s, iron, zinc and magnesium. They’re so nutrient-dense, consultants say they’re among the best methods we will feed a rising international inhabitants.
Mussels can even assist us clear up the oceans. Like all bivalves, they feed by filtering water. This removes waste particles, like industrial fertilisers, and carbon dioxide. Farmed mussels don’t use any land, recent water or feed, plus the ropes they’re grown on can present habitats for different sea creatures. Paella, anybody?
7. Cereals and grains
Most of us know that cereals and grains ought to make up a big a part of a wholesome, balanced weight-reduction plan, however the WWF warns that ‘there’s a urgent have to differ the kinds of cereals and grains grown and eaten’. That’s as a result of counting on one or two crops has damaging penalties for each the surroundings and our well being.
From an environmental perspective, monoculture (solely rising one crop) has an affect on soil well being – so farmers want to make use of further fertilisers – and will increase the danger of illness and pest outbreaks, so massive quantities of pesticides and herbicides are then sprayed on the crop. These chemical substances in our meals aren’t nice for us, and we’re lacking out on a variety of nutritional vitamins and minerals if we solely eat sure cereals and grains, reminiscent of white rice, maize or wheat.
Subsequent time you buy groceries, search for alternate options reminiscent of buckwheat, teff, spelt and quinoa. Not solely will you get out of your cooking consolation zone, you’re additionally supporting your long-term well being and that of the planet.

Let’s assume it may be left as grassland for cows. If that land can also be a part of a regenerative farm, the farmer will likely be rearing livestock alongside rising crops in a bid to enhance soil well being.
The pure fertiliser produced by the cows reduces or eliminates the necessity for chemical fertilisers, whereas the animals’ hooves churning up the soil additionally helps it to soak up extra carbon. There may be some analysis to indicate that grass-fed beef may be carbon-negative within the quick time period and carbon-neutral in the long run, however different scientists argue that even when grass-fed cows do contribute to storing carbon, that is solely below superb circumstances. So, there are advantages to rearing grass-fed cattle however they’re not going to resolve local weather change alone.
The EAT-Lancet Fee, which developed the planet nutritious diet, does permit for consuming some crimson meat and if you will eat beef, it must be the ‘least-worst’ possibility. However bear in mind to go for regionally grown grass-feed beef to additional cut back its carbon footprint.
9. Oats
Not satisfied by grass-fed beef? There are some crops that may thrive in probably the most inhospitable locations – enter, oats. They’ll develop at excessive altitudes and with out chemical fertilisers, and may be sown between different crop harvests to assist replenish the soil; referred to as a ‘break crop’. Oat milk makes use of loads much less water than different plant alternate options too, reminiscent of soy or rice milk.
Oats may be referred to as a ‘superfood’. They’re identified to assist decrease unhealthy levels of cholesterol and may cut back hypertension, whereas serving up respectable quantities of fibre and nutritional vitamins reminiscent of magnesium and zinc per serving. Once more, keep on with native varieties somewhat than imported oats to cut back the environmental affect of transport.
10. Figs
Figs style good and do good. For starters, practically 1,300 hen and mammal species eat figs – making them some of the relied-on fruits on the planet – who then go on to unfold the seeds far and extensive. Some scientists say planting fig bushes might help regenerate deforested landscapes, restoring biodiversity, whereas the bushes are additionally fairly resilient to local weather change.
For us, figs might help with digestion, weight administration, bone well being and hypertension. Figs develop in most Mediterranean nations, decreasing their meals miles, however you can even plant a few varieties within the again backyard. And also you’ll get an Adam and Eve fancy gown costume totally free…
And the worst?
No surprises right here – there’s an amazing quantity of proof to indicate beef and dairy are the worst meals for us and the planet. Greenhouse gasoline emissions, land use, water use, transport prices and low quantities of vitamin for all the hassle concerned, mix to make farmed meat and dairy merchandise a nasty alternative for everybody.
Analysis by the Meals Requirements Company discovered 73% of us need to purchase meals with a low environmental affect. The unhealthy information is getting that info included on meals labels continues to be a way off, however the excellent news is that articles like this might help.
Subsequent time you’re planning meals, make the planet a visitor at your desk. This may assist guarantee there’s at all times sufficient meals out there for everybody.
