Family and friends may not have accurate or evidence - based nutrition knowledge. Magazine ads are often designed to promote products rather than provide reliable nutrition info. Social media posts can be unregulated and full of misinformation. Medical associations, on the other hand, base their information on scientific research and medical expertise, making them a reliable source for nutrition - related information.
