Growing your own vegetables indoors in a warm, well-ventilated space is the most sustainable way to eat vegetables, a new study has found.
Vegetables grown indoors in the UK are typically grown in greenhouse systems, which can grow a lot of vegetables but are not as nutrient dense as indoor growing systems.
Growing vegetables in the same greenhouse system with no light or ventilation can be a lot harder to manage, so the best option for veg enthusiasts is to grow their own indoor vegetable garden.
According to the research, indoor vegetable gardens can provide up to 4,000 calories per day.
That is about 30 per cent more than indoor growing plants, which provide 2,500 calories.
Researchers also found that indoor growing can help people with obesity reduce their weight, and help them avoid chronic illnesses.
The research, published in the British Journal of Nutrition, also found growing vegetables in a greenhouse can help reduce air pollution and carbon emissions, which could help reduce the global warming emissions caused by the burning of fossil fuels.
The study looked at 1,000 indoor vegetable growing systems across the UK and found that the average indoor greenhouse has around 50 per cent less nitrogen and phosphorus than a typical greenhouse.
It also found a 10 per cent increase in plant productivity, which is related to increased carbon and nitrogen uptake.
If a greenhouse was fully grown and the plant’s leaves were in full flower, the research found the plants’ production was 3 per cent higher, and the carbon dioxide emissions were reduced by 6 per cent.
The UK has around 300,000 greenhouse systems for vegetable production, and as a result, there are about 100,000 vegetarians in the country, according to the Vegetarian Society.
There are currently more than 20,000 garden centres in England, which offer vegetables as well as fruit, vegetables, nuts and seeds.
