UK households threw away 6.0 million tonnes of food and drink in 2022, about 88 kg per person, or 210 kg per household (WRAP, Household Food and Drink Waste in the UK 2022). That is total waste (edible plus inedible). High-income countries average about 81 kg per person per year at the household stage (UNEP Food Waste Index 2024).
Those are not “1,000 kg per household.” They are not “a third of the food you buy” (that FAO one-third figure is about food produced, not a typical shopping basket). And USDA’s ~31% figure is consumer-level food supply, not “30% of food a family purchases.”
If you want a labelled range for your household size and region, use the household food waste calculator, still estimates, still WRAP/EPA scopes, not a second encyclopaedia.
Most of what you can actually change is bought-not-cooked: the spinach you meant to use, the leftovers you never labelled, the second jar of the same sauce. This piece maps where that happens in a kitchen, then seven habits that stick. Money (pounds and dollars) lives on the sibling: what household food waste costs. If you want the product that ranks what to cook first, see the food waste reduction app. For the shelves themselves, the pantry inventory is the sibling hub.
The honest stat (with sources)
| Metric | Geography | Year | What it measures |
|---|---|---|---|
| 6.0 million tonnes; ~88 kg/person; ~210 kg/household | United Kingdom | 2022 | Household food and drink waste, edible + inedible (WRAP 2022) |
| ~81 kg per person per year | High-income countries | 2024 index | Household-stage food waste only (UNEP 2024) |
| ~31% of the food supply | United States (consumer level) | USDA ERS (ongoing series) | Food available in the supply, not “share of groceries you bought” |
WRAP’s 2022 report also splits edible waste at 4.4 million tonnes (73% of that household total). Use that split if you talk about “food you could have eaten.” Do not mix edible tonnes with the 210 kg household figure without saying so.
What these numbers are not
- Not FAO 2011 “one third of food produced.” Production and household shopping are different scopes.
- Not the global 1.05 billion tonnes in UNEP’s index. That is every sector, every country, not your bin.
- Not restaurant or retail waste. Those are real; they are not this article.
- Not a 2024 WRAP kilogram figure. The report cited here is the 2022 UK household study.
UK vs US vs “average family”
There is no single “average family” number that travels. WRAP is UK households in 2022. UNEP’s 81 kg is a high-income household-stage average. US consumer-level supply loss is a different statistic. If someone quotes “the average household wastes X kg,” ask: which country, which year, edible or total, household or whole supply chain.
Where the waste happens (5 places)
In rough order of how much kitchen waste they cause, this is a map of habits, not a WRAP table:
1. The fridge back, behind something else. A leek, a half-can of beans, a tub of yogurt. Out of sight, forgotten until it's gone. This is where most fresh-vegetable waste happens.
2. The bread bin / counter, going stale. Bread is among the most-wasted items in many UK kitchens. Bought weekly, only half eaten, stales by Thursday, gets thrown out by Saturday.
3. The fridge door, expired condiments. Less waste by weight than the above, but a steady drip. Half a jar of pesto, a jam from 2023.
4. Leftovers in opaque containers. Saved with good intentions, never seen again. Discovered three weeks later, "what is this?", binned.
5. The "I'll make it eventually" produce. Bought because it looked good or seemed virtuous. Sat. Wilted. Got thrown out a week later.
Fix the layout and the visibility of these zones and the waste drops. The fridge organization method is the physical version; a pantry you can actually see is the dry-goods version.
The 7 fixes (one per habit)
Ranked by how reliably people stick to them.
Fix 1: Designate an "eat me first" shelf. Already covered in fridge organization. The single most effective change. Time to implement: 5 minutes. Stick rate: high.
Fix 2: Freeze bread the day you buy it. Cut into the slices you'll use, freeze in a zip-lock bag, toast straight from frozen. Bread waste drops hard. Stick rate: high once tried.
Fix 3: The 90-second pre-shop check. Before you leave for the supermarket, look at the fridge and pantry for 90 seconds. Write down what you have. Don't buy duplicates. The single biggest cause of fridge waste is buying things you already have. Stick rate: medium, needs to become a habit.
Fix 4: Cook the wilting things on Sunday. Soup, stir-fry, frittata, fried rice. Pick whichever your wilting things fit into. One pan, twenty minutes, two more dinners worth of food saved. Stick rate: medium. Plan from the ingredients you already have if you want the app to pick the pan.
Fix 5: Label leftovers. A piece of tape on the lid with the date. You'll eat the 2-day-old leftover; you won't eat the 8-day-old one. Without the date, you can't tell which is which, so all leftovers become 8-day-old. Stick rate: medium-high. USDA FSIS: cooked leftovers in the fridge for 3–4 days; freeze if later (leftovers and food safety). Apply that window to the day you cooked on how long leftovers last.
Fix 6: One "eat down the freezer" night per month. No new groceries that night. Cook from what's already in the freezer. You'll be surprised what's in there. Stick rate: medium.
Fix 7: Track your inventory. App, paper, whatever. The act of knowing what you have changes shopping behavior more than any other intervention. Dietrack does this automatically; a notebook works too. Stick rate: high if it's automated, low if manual.
The 30-second weekly check
Once a week, open the fridge and the freezer. Spend 30 seconds. Identify the 2-3 things that will go bad first. Plan tonight's dinner around them. That's it. The check itself is the intervention, you can't waste what you've noticed.
If you do this for a month, the muscle memory builds and the check shrinks to 10 seconds because there are fewer surprises in the fridge. That's the goal state.
The "shelf-of-doom" again
If only one of the seven fixes sticks, make it Fix 1 (the eat-me-first shelf). Every kitchen has a shelf where things go to die. Naming it changes the dynamic. Things on that shelf get cooked. Things in the back of the fridge, behind the milk, do not.
You don't need a label. You don't need a sign. You just need to know where the shelf is and use it.
After the habits: snap the fridge so “eat me first” isn’t a sticky note. Dietrack is free on iOS and Android. It does not cut household waste by a promised percent.
FAQ
Is composting a fix?
It's a fix for the planet (the food doesn't go to landfill, doesn't produce as much methane. It's not a fix for your wallet) you've still bought food you didn't eat. Compost is the safety net, not the strategy.
Are "ugly produce" boxes a fix?
They're a fix for systemic waste (food rejected before reaching consumers). They're not a fix for your waste. If you buy a box of ugly produce and don't cook it, you've moved the waste, not eliminated it.
Are best-before dates legally binding?
In most countries, no, "best before" indicates quality, not safety. "Use by" is the safety date. Many people throw out food on the best-before date when it's perfectly fine. Use your senses (smell, look, taste a small bit). The exception: high-risk foods (raw meat, fish, soft cheese, deli items) where you should respect the use-by.
Can a single household actually move the needle on national food waste?
Household waste is a large slice of what WRAP and UNEP measure in rich countries. You cannot personally fix global tonnes. You can change the 210 kg-shaped problem in your kitchen. That's the job this article is for.
