Antioxidant Kitchen is a plain-English blog about the polyphenols, flavonoids and carotenoids hiding in ordinary food — what they actually do, where to find them, and why a plate full of colour beats any single pill.
Plants make these compounds to protect themselves. We borrow the benefit when we eat them.
You've seen "antioxidant" on labels for years, usually attached to a powder or a juice with a big number on the front. This blog goes the other way. It's about the real foods those compounds actually come from — the deep red of a pomegranate, the near-black of a blackberry, the orange of a roasted carrot — and the plain-English story of what each family of pigment does inside the body.
No cleanses, no miracle claims, no invented percentages. Just how polyphenols, flavonoids and carotenoids behave, which everyday foods carry them, and why eating a wide range of colours does more than chasing any single "superfood" ever could.
Every colour on your plate is a different family of protective compound. Red isn't purple, orange isn't green — and the point isn't any one of them, it's the range. Here's how to read a plate by its colours and build variety in without a spreadsheet.

The pigment that gives a food its colour usually is the antioxidant. Match the swatch to the food group, and see what that colour tends to do — no numbers, just the honest picture.
Red pigments cluster around anthocyanins in fruit and lycopene in cooked tomatoes — the family most often linked with heart and blood-vessel health.
Pomegranate · red cabbage · tomatoes · strawberries · red grapes
The darkest foods carry the highest anthocyanin load. These are the pigments studied most for brain and memory support.
Blueberries · blackberries · aubergine · black rice · plums
Orange means carotenoids — fat-soluble pigments the body can turn into vitamin A. They absorb far better with a little oil on the plate.
Carrots · sweet potato · squash · apricots · persimmon
Behind the chlorophyll, leafy greens are quietly rich in lutein and zeaxanthin — carotenoids that concentrate in the eye.
Spinach · kale · broccoli · peas · matcha
Yellow spans citrus flavonoids and the vivid curcumin in turmeric — bright, distinctive compounds with a long place in the kitchen.
Turmeric · lemon · yellow peppers · corn · saffron
Pale doesn't mean empty. Onions and garlic carry sulphur compounds and quercetin; cocoa and tea bring some of the densest polyphenols of all.
Garlic · onion · cocoa · green tea · mushrooms
Heat, water and time change what survives on the plate. Here's the honest direction of travel for a few common foods — not exact figures, just which way things tend to move.
It's a broad label for compounds that help keep the body's natural oxidation in balance. Your cells produce reactive molecules called free radicals as a normal part of living; antioxidants — many of them plant pigments — help keep that process in check. It isn't a single ingredient, it's a job that thousands of different compounds do to different degrees.
For most people, no. Whole foods deliver antioxidants alongside fibre, vitamins and a whole mix of compounds that seem to work together. Isolated high-dose supplements have sometimes performed worse than expected in studies, and a pill can't copy the variety of a colourful plate. Food first is the sensible default.
Not necessarily. The body actually uses some oxidation for useful things, like fighting infection and adapting to exercise. The goal is balance and variety, not maxing out a number on a label. A steady, colourful diet does far more than chasing the highest score on any single food.
No. Ordinary, affordable foods carry plenty — onions, carrots, cabbage, apples, beans, tea, coffee, herbs and everyday berries all pull their weight. "Superfood" is mostly a marketing word. Variety across cheap, colourful staples beats one pricey import you eat occasionally.
It depends on the food. Cooking makes some compounds — like lycopene in tomatoes — easier for your body to use, while long boiling can wash others away. There's a whole guide on this on the site. The short version: vary your methods, don't drown vegetables, and eat some things raw and some cooked.
No. It's general nutrition information for interest and education. It isn't a treatment for any condition and isn't a substitute for a doctor or dietitian. If you have a health condition, take medication, or are considering supplements, talk to a professional before making big changes.
