Throwing away good food while the rest of the world starves is not only an ethical issue, it reflects our unsustainable food system. We need to think about how we produce food, what we consume and what we discard…
For aeons, parents have guilt-tripped children into eating their dinner because less fortunate children are starving somewhere in the world.
Judging by the bounty seen in restaurants, grocery stores, at markets and on the streets, it’s hard to believe half a billion people in the world are going hungry, while the rest are either making terrible food choices or are gluttons.
By 2050, the world’s population growth is projected to be 10 billion (according to the EU Commission’s Health and Food Safety estimates).
Our resources are not infinite, but the way we treat them, you’d think electricity comes from the plug, meat from the supermarket, our greens from the greengrocer and water from the tap.
It takes money to produce all that – money that could be used to drive development in other areas and help the needy.
Food production costs water, it produces emissions, reduces biodiversity and drives climate change.
Our marine ecosystems are being degraded, drought is wreaking havoc, forests are disappearing and millions of people the world over are hungry. We need to start thinking about how we manage and produce food, what we eat and food waste.
Worldwide, 2 billion people are obese, while half a billion starve. In South Africa, the latest Discovery Health figures show 60% of women and 38% of men are clinically obese, with 14 million people going hungry daily.
Yet we throw away up to a third of all our food.
Dr Nadene Marx-Pienaar, from the food retail division in the department of consumer science at Pretoria University, breaks down some staggering figures about our throwaway society.
“It’s estimated that 177kg of food waste is generated annually by the average South African (according to a 2013 study on it by the CSIR),” she said.
“Findings from the study by the Department of Consumer Science at the University of Pretoria on food waste among Gauteng households done in 2014/15 revealed that fruit and vegetables outranked all the other food groups in terms of food mostly wasted by households. Second were cereals and breads (including pasta, rice, cakes and pastries), with dairy products (including milk, yoghurt and cheese) in third place. The fourth most wasted food type is meat, poultry, fish and eggs.
“The self-reported percentage of purchased food wasted indicated that 31% of respondents waste more than 30% of the fruit and vegetables they buy, 34% waste more than 20% of cereals and breads, 27% waste more than 20% of dairy products, and 20% waste more than 20% of the meat, poultry, fish and eggs they buy.”
A 2013 CSIR study titled “The magnitude and cost of food waste in South Africa” found the costs to the economy were estimated at R61.5 billion a year, or 2.1% of our GDP.
“At the same time, 70% of poor urban households in South Africa live in conditions of food insecurity.”
Food is treated as a disposable commodity, especially in developed countries.
“Yet, almost one in seven people globally are estimated to be undernourished.
“Food waste does not only impact on food security, but has environmental impacts, in the form of wasted resources and emissions,” they noted.
Food waste isn’t only what we throw in the bin, though – it includes that which is lost during and after agricultural production; storage; manufacturing; distribution; and consumption, they say.
“The largest costs of food waste occur in food distribution (R19.6bn), followed by processing and packaging (R15.6bn), and agricultural production (R12.5bn). To meet the challenge of feeding growing populations and addressing food insecurity, massive reductions in the amount of food wasted across the food supply chain in South Africa are needed.”
Marx-Pienaar added: “Date codes are the most reported reason for wasting food. This is followed by poor product appearance and poor planning in terms of purchasing, preparation and storage.”
It’s important to note the difference between “best-before” and “use-by”: the former relates to quality, and the latter to safety.
“Use-by” dates mean food can be consumed until that date – after that, if it hasn’t been frozen or preserved, it’s not fit for consumption.
If food has reached its “best before” date, it’s still safe to eat, but it may not be at its best.
Best-before dates are important guidelines to ensure food safety, but they’re not cast in stone, as many foods are still good to eat days – sometimes weeks – after they’ve expired.
Some foods, such as cold meats and ready meals, could become dangerous, but other foods – such as honey, cornflour and sugar – don’t go off and the dates have the psychological effect of encouraging consumers to throw out perfectly good food.
Responsible retailers and manufacturers are doing their bit to mitigate this wastage: last year, their donations enabled FoodBank to feed 170 000 people with 3 350 tons of food and helped 550 non-profit organisations. That’s R23.5m worth of food reclaimed.
Lamees Martin, FoodBank SA’s marketing and communications officer, explained: “We collect edible surplus food from manufacturers, wholesalers and retailers, and redistribute this food to verified NPOs that collectively feed thousands of hungry people daily.
“As a recipient of food donations, FoodBank SA has a responsibility to its beneficiaries to carefully check all products received at its warehouses… such as checking all dates on all products and rejecting expired stock.”
France and Italy have recently been in the news for introducing laws governing food waste. In France, retailers are fined for throwing away food; in Italy, they’ll soon be incentivised for donating unsold food.
As consumers, we have the power to vote with our forks to reduce waste. If we all put more thought into what we eat (and do so sustainably), prepare real food at home (rather than buy processed food) and waste less, we’d not only save resources, but we’d also be teaching our children to prepare for a future in which there’s enough to go around.
