Healthy diet
diet that helps maintain or improve general health
A healthy diet (or healthful diet) is a diet that maintains or improves overall health, providing the body with essential nutrition: water, macronutrients such as protein, micronutrients such as vitamins, and adequate fibre and food energy.
A healthy diet may contain fruits, vegetables, and whole grains, and may include little to no ultra-processed foods or sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although additional sources of vitamin B12 are needed for those following a vegan diet. Various nutrition guides are published by medical and governmental institutions to educate individuals on what they should be eating to be healthy. Not only advertising may drive preferences towards unhealthy foods. To reverse this trend, consumers should be informed, motivated and empowered to choose healthy diets. Nutrition facts labels are also mandatory in some countries to allow consumers to choose between foods based on the components relevant to health. The lack of a healthy diet contributes massively to the global disease burden, imposing immense health, economic and social costs.
In 2025 only 30.8% of children aged 6 to 23 months, and 62.7% of women aged 15 to 49 years, consumed a minimally diverse diet. In 2024, 31.9% of the global population could not afford a healthy diet, compared to 36.9 percent in 2020 and 38.4 percent in 2017.
“Healthy diet” enters the record as diet that helps maintain or improve general health. Crown Archives preserves that source wording while asking what Healthy, diet and helps can confirm, complicate or overturn.
Why this record matters
“Healthy diet” is worth following because a concise public description often conceals a longer documentary argument. Here, Healthy, diet and helps provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q5906358. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025, 2024, 2020 and 2017.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
