Sources and limitations
A guide to eating has to stand behind every word, because people easily take food advice personally. Here we explain where our information comes from, why there are so few numbers in our texts, and how to check information you come across elsewhere.
A guide can explain general principles. Only a professional who actually sees a person can tailor eating advice to them.
How we choose sources
Our foundation is the World Health Organization's advice on healthy eating. It summarises a large body of research and is revised as new evidence emerges.
Information on food labelling is based on the Eurasian Economic Union labelling rules (TR CU 022/2011). We summarise them in general terms and do not claim legal precision. Labelling rules differ by country, but listing ingredients in descending order by weight is common practice; check your local rules.
We deliberately use few numbers: we only quote figures taken from the sources named here and never invent our own targets.

How to check advice about food
Ask yourself who wrote the advice and what they want you to buy. If a recommendation ends with a link to a shop, it deserves a closer look.
Compare the advice with the WHO's position and your own doctor's view. Reliable information usually sounds measured, talks about variety and doesn't promise instant change.
Notice how a text talks about people. Content that shames people for how they look, splits foods into forbidden and allowed, or uses scare tactics rarely helps and can increase anxiety around food.
If the advice concerns treatment, tests or special eating for an illness, the only reliable person to ask is your own doctor, who knows your history.

This guide draws on the World Health Organization's general advice on healthy eating and on food labelling requirements as they stood when it was written. Recommendations are updated from time to time, and decisions about your own eating are best made together with a doctor.
