Put things on the plate

Tap to add, tap again to take off. There is no right plate.

Pick something and the next few hours will appear here.

What it is made of

Open any food. No time, no consequences — just what the thing actually is.

An apple

Mostly water, wrapped around sugar the apple made itself and a mesh of fibre you cannot digest. The sugar comes packed inside that mesh, so it gets out slowly.

A glass of apple juice

The same sugar as the apple with the fibre mesh taken out. Nothing is left to slow it down, so it arrives all at once. This is the clearest example in the whole game: same fruit, different speed.

A bowl of plain oats

Long chains of glucose locked together as starch, plus a kind of fibre that turns thick and gluey in water. Your enzymes have to cut the starch chain one link at a time, and the gluey part makes that slower still.

Two eggs

Protein is a folded chain of amino acids. Heat unfolds it — that is what you are watching when the clear part turns white. Your stomach then cuts the chain back into its links.

A scoop of beans

Both at once: protein chains and fibre your enzymes cannot cut. The fibre travels the whole way to your large intestine still in one piece, which is where the bacteria that live there get to it.

A piece of grilled chicken

Muscle, which is protein arranged in fibres. Cooking unwinds them, which is why cooked meat pulls apart and raw meat does not.

Two slices of white bread

Starch with the bran and germ milled away. The chains are the same glucose chains as in the oats — there is just nothing left in the way, so the cutting goes fast.

Two slices of wholegrain bread

The same starch, with the outer layer of the grain still in it. That layer is the fibre, and it is the difference.

A fast-food burger

Protein from the patty, fast starch from the bun, salt through all of it, and usually sugar in the sauce and the bread. Each piece behaves the way that piece behaves — there is nothing special about it being a burger.

A portion of fries

Potato is starch. Cut into strips and fried, the outside dries and browns while the inside stays soft — two different textures from one vegetable and one pan.

A can of soda

Sugar already dissolved in water. Nothing has to be cut or unwrapped, so nothing slows it down. It is the fastest thing on this list by a wide margin.

A glass of milk

Protein and fat suspended in water, plus milk's own sugar. The protein and fat are why it does not behave like juice.

Raw carrot sticks

Water held in a stiff fibre frame. That frame is why a carrot snaps, and it is the same stuff your enzymes cannot cut.

A glass of water

Water. It is not a trick option — several things on this list make you thirsty, and this is what answers that.

Is organic food more nutritious than the same food grown conventionally?

The USDA Organic seal certifies HOW something was farmed — which substances could be used on it, and how the soil and animals were handled. It is a rule about the farm. It is not a measurement of what ended up inside the food.

People disagree about this

Organic produce is nutritionally better.
Some studies find higher levels of certain compounds in organically grown crops.
The nutritional difference is small or absent.
Reviews comparing the two find differences that are inconsistent between studies and small where they appear at all.

Because the label is on everything and almost nobody is told what it actually certifies. Knowing that it is a farming rule rather than a nutrition rule is worth more than either side of the argument.

USDA National Organic Program

An apple is not an apple

Two apples are not the same. The differences are recorded in public, by named agencies, and you can look them up. That is a better thing to know than any verdict this page could hand you.

Which variety it is: A Honeycrisp and a Red Delicious are both apples and are not the same food. Varieties of one crop differ in sugar, acid, fibre and vitamin content, sometimes by a lot. Supermarket varieties were often selected for how well they ship and store rather than for what is in them.; Check it: Look up two named apple varieties in FoodData Central and put the numbers side by side.; USDA FoodData Central
How ripe it was when it was picked: Produce that has to travel is picked before it is ripe so it survives the trip. Ripening on the plant and ripening in a container are not the same process and do not end in the same place.; Check it: Taste the same fruit in season locally and out of season shipped. You do not need a laboratory for this one.; USDA FoodData Central
How long ago it was picked: Some vitamins break down with time, light and warmth after harvest — vitamin C and folate most noticeably. A vegetable that spent two weeks in transit is not the same as one picked yesterday, even if both are the same variety.; Check it: Frozen produce is usually frozen within hours of picking, which is why it often measures better than 'fresh' produce that travelled a long way. That surprises people and it is in the data.; USDA FoodData Central
The soil and how it was grown: Soil mineral content, water and farming practice all affect what ends up in a plant. The size of that effect differs a lot by nutrient — minerals track the soil more closely than vitamins the plant makes itself.; Check it: Harder to check yourself. This is the one on this list to hold most loosely, and it is why the entry says which nutrients it applies to rather than claiming it for all of them.; USDA FoodData Central
What was sprayed on it: Pesticide residues are measured every year on food bought in actual shops, and the results are broken out by crop and by country of origin. Some crops carry residues far more often than others. This is a public record and almost nobody reads it.; Check it: Open the PDP report for something you buy every week. The detection rates differ enormously between crops.; USDA Pesticide Data Program
What was put in during making: Additives are listed on the package by law. Which additives are permitted differs between countries — a substance allowed in one place can be restricted in another, which means two competent regulators read the same evidence and came to different conclusions.; Check it: Compare the ingredient list of the same brand-name product bought in two countries. People post these side by side and the differences are real and checkable.; FDA food additive and GRAS listings

Still argued over

These are the questions people most want answered, which is exactly why they are not answered here.

Do pesticide residues at the levels usually measured on food affect a person's health?

Not in dispute: Residues are present, they are measured every year, the measurements are public, and legal tolerances exist and are set by the EPA. All of that is documented and checkable.

Typical residues are far below levels shown to cause harm, so the exposure is not a meaningful risk. Tolerances are set with margins below levels where effects were observed in testing, and measured residues usually fall well under the tolerance.
The margins may not account for everything that matters. Long-term low-dose exposure, mixtures of several substances at once, and effects during childhood development are harder to study than single-substance testing and are argued to be less well covered.

Is fruit and veg less nutritious now than it was fifty years ago?

Not in dispute: Nutrient content varies by variety, soil, ripeness and storage. That much is settled and is the top half of this page.

There has been a real decline. Comparisons of old and new food composition tables show lower values for several minerals in some crops.
The comparison does not support the conclusion. The varieties grown changed over the same period, and so did the laboratory methods used to measure them. A difference between two tables can come from either without the food having changed.

It will not tell you whether your food is safe or dangerous. That question is genuinely unsettled at the levels usually measured, and a screen that answered it confidently would be selling you something.

Nothing here says food will hurt you. Food is not clean or dirty. Some apples have more of some things in them than others, people write it down, and you are allowed to go and read what they wrote.

This is what typically happens. Two people can eat exactly this and their bodies do different things with it, which is measured and normal. Nothing here is a prediction about you.

There is no score and no winning plate. Foods are not good or bad. They do different things, and this shows what they do.

This treats each food as one thing so you can build a plate. Real ones differ — by variety, by how ripe it was picked, by how long it travelled, and by what was sprayed on it. All of that is written down in public and you are allowed to go and read it.

If something about eating is worrying you or somebody you love, that is a conversation for a doctor or a registered dietitian — a real one, who can ask you questions a screen cannot.

What this cannot show you

What happens to you specifically: Responses to identical meals differ between people. This shows a typical pattern and cannot know yours.
Anything over months or years: It runs a few hours. Long-run effects depend on far more than one meal, and a game that showed a decade from one lunch would be a threat, not a simulation.
Exact grams of anything: Amounts vary by brand, portion and preparation. The label on the package and USDA FoodData Central are where the real numbers live.
Which apple, and where it came from: Two apples are not the same food. Variety, ripeness at picking, time in transit and what was sprayed all differ, and all of it is recorded in public. This screen models 'an apple' so you can build a plate.
Whether a food is right for you: Allergies, conditions, medicines, budget, culture and what is actually in your kitchen all decide that. None of them are on this screen.
Anything about weight or body shape: Deliberately. This shows what happens inside over a few hours. It will never show a body changing.

Where this comes from

Fibre is a carbohydrate your own enzymes cannot cut apart. It travels all the way to your large intestine still in one piece, and the bacteria living there feed on some of it. Dietary Guidelines for Americans, 2025-2030
Eating carbohydrate together with protein, fat or fibre makes the rise in blood sugar flatter and slower than eating the same carbohydrate on its own. The stomach empties more slowly. Dietary Guidelines for Americans, 2025-2030
Two people eating exactly the same meal can have measurably different blood-sugar responses to it. This is why nothing here is a prediction about you. National Institute of Diabetes and Digestive and Kidney Diseases (NIH)
Salt makes your body hold on to water, and it makes you thirsty. That is why a salty meal is often followed by wanting a drink. National Heart, Lung, and Blood Institute (NIH) — sodium and blood pressure
The current federal guidance says no amount of added sugar is recommended, and works to a ceiling of ten grams in a single meal. Dietary Guidelines for Americans, 2025-2030
Starch is a long chain of glucose joined end to end. Digestion cuts the chain into single links, and an enzyme in your saliva starts doing it before you have even swallowed. MedlinePlus (U.S. National Library of Medicine)
