I'm wondering where to ask about the consumption of iron and Daily Value.
If 150% RDV (Recommend Daily Value) of iron is consumed in a day, from foods, is that bad?
If you’re asking about this in terms of exercise or fitness, then Physical Fitness might be a good option. The help section says that it is on-topic to ask about:
- nutrition as it relates to exercise
But the following topics are off-topic:
- nutrition unrelated to exercise, such as food safety, nutritional needs for children, etc.
- wellness, general health, medical advice and injuries unrelated to exercise
If you’re a Vegan or Vegetarian and are worried about getting enough Iron, then you could ask on Veganism & Vegetarianism which says that topics related to:
- How to stay healthy living while living a veg*n.
Personal nutrition is generally off-topic on Biology and Medical Sciences:
Which questions are off-topic?
- personal medical questions and health advice
Often asked questions that are off-topic include:
- medical advice for yourself or others
- questions about nutrition and diet that aren't directly connected to medical treatment
If you were asking about the biology of iron usage, then Biology might be a good option. Similarly, if your question about iron is directly related to understanding a medical treatment (but is not a request for medical advice), you might be able to ask it on Medical Sciences. If you go with either of those options, though, you should be very clear about how your question is about science, not personal medical or nutritional advice.
If you're asking about the accuracy of a published claim about Iron (for example, if you read somewhere that eating 100% of your RDV of Iron is actually bad), then you could ask about the truth of that claim on Skeptics. Note that this must be a notable claim that has been made publicly, so be sure to have a citation for it:
Skeptics Stack Exchange is for challenging unreferenced notable claims, pseudoscience and biased results.
If you have a question about the accuracy of public claims made in the media or elsewhere, if you're interested in the evidence behind what you hear or read, then you are in the right place.
