The concept of “healthy food” is often presented as simple and universal: eat more fruits and vegetables, avoid processed foods, choose low-fat or low-sugar options, and your body will thrive. Grocery stores reinforce this idea with neatly labeled aisles, influencers promote it through curated meal plans, and public health campaigns distill it into easy slogans. Yet despite these well-meaning efforts, the reality is far more complex. Foods widely considered healthy are not always healthy for everyone, and in some cases, they can even be harmful. Health is deeply individual, context-dependent, and influenced by biology, culture, mental well-being, and access. Treating “healthy food” as a one-size-fits-all solution oversimplifies nutrition and can lead to unintended consequences.
