@92d47f9f: You make a valid point that some healthcare providers do recommend one-size-fits-all diets, and that peer-reviewed research is not always accurate or unbiased. It's important to consider multiple sources of information and to be critical of any claims that are not supported by evidence.
However, peer-reviewed research is still considered an important benchmark for accuracy in the scientific community because it involves a rigorous process of review and critique by experts in the field. While it's true that some studies may be influenced by funding or other biases, the peer-review process is designed to minimize these factors and ensure that research is conducted and reported in a transparent and objective manner.
Ultimately, it's up to individuals to weigh the evidence and make informed decisions about their health. It's always a good idea to consult with a qualified healthcare professional before making any major changes to your diet or lifestyle.
