About GesundeFakten
GesundeFakten explains what research actually knows about nutrition and health. Every article is grounded in the evidence, not in the latest trend or in anyone’s opinion.
The idea came from an annoyance many people will recognize. If you want to know whether psyllium husks help with constipation, or whether it’s fine to reheat cooked beetroot, you can find ten answers within minutes, and they contradict one another. One site promises miracles, the next warns of dangers, and hardly any of them says what they base their claims on. The actual studies are often locked behind paywalls and written in a technical language that almost nobody outside medicine reads.
That’s why GesundeFakten exists. Every article starts with a question from everyday life and ends with an answer based on published research in humans. Preferably on review papers, which pool the results of many individual studies. The sources are listed beneath every article and link directly to the original paper, so you can check every claim yourself.
What matters to us
When we say something is backed by evidence, it is. Anything that can’t be supported by studies either stays out of the article or is explicitly flagged as an open question. If a study was done only on mice, we say so. And if a food has a measurable effect but only a small one, the text says exactly that and no more.
It’s just as important that you can understand the texts. We turn statistics and technical terms into clear sentences, and where numbers help, you’ll find them in a table. Many articles answer very practical questions, such as how long a food keeps, how much of it was used in studies, or what to look for when shopping.
Mistakes happen all the same. If you find one, you can get in touch at any time. We’ll check your report, correct the article and note what has changed.
What you’ll find here
There are now more than 200 guides on nutrition, health and exercise, all available in eleven languages. On top of that come recipes based on the evidence, many of them from anti-inflammatory cooking. For everyday use, there are tools such as the vitamin D converter and the lab values converter, and on kochen.gesundefakten.com you can cook recipes step by step using voice control.
Our editorial policy describes in detail the rules we follow when choosing topics and assessing studies.
Who is behind it
GesundeFakten is run by me, Simon Gütter. I’ve been working on health optimization for over ten years, mainly with plant-based nutrition and wild herbs. I’m interested in nutrition as a whole, meaning how foods work together and how mindful cooking fits into normal everyday life. Along the way I’ve come across countless promises that didn’t hold up to closer scrutiny. That’s why I read the studies myself before passing anything on, and that is exactly the standard this site aims to meet.
What this site can’t do
GesundeFakten is no substitute for seeing a doctor. We don’t make diagnoses or recommend personal dosages, and our calculators merely convert units. If you have symptoms, take medication or are unsure, you should talk to a doctor or a pharmacist.
