Phytochemicals

Polyphenols, carotenoids, glucosinolates and many more: thousands of compounds that only plants make. They are considered protective for the heart, blood vessels and cells.

Keep an eye on it when eating animal products

What the body needs it for

  • Protect cells from oxidative stress
  • Can dampen inflammatory processes
  • Support a diverse gut flora

How much you need

There are no fixed reference values. The DGE recommends at least 3 portions of vegetables and 2 portions of fruit per day – as colourful as possible.

Where they are found

  • Berries and red grapes: anthocyanins
  • Broccoli, kale, Brussels sprouts: glucosinolates
  • Tomatoes and carrots: carotenoids
  • Onions and garlic: sulphides
  • Pulses: saponins and phytoestrogens
  • Herbs, spices, cocoa and green tea: flavonoids

How to make the most of it

  • Eat colourfully: each colour stands for different compounds.
  • Eating a lot of meat often crowds out vegetables – make vegetables the main side.
  • Eat some raw and some cooked: heat makes some compounds more available.
