From just well to vigorous
Those five chips above rank physical health words by strength, weakest first. Well just means you are not ill. Fit adds exercise and stamina. Strong points to muscle and resilience. Robust suggests a body that shrugs off germs, and vigorous adds energy and drive, often used for older people who stay active.
For food the scale is flatter. Nutritious is factual, wholesome is warmer and a bit old-fashioned, and good for you is the friendly spoken version.

Healthy vs healthful, and other mix-ups
Healthy vs healthful: some careful writers keep healthful for things that make you healthy (a healthful meal) and healthy for things in good health. Most readers now accept healthy for both, so either is fine outside very strict style guides.
Clean and hygienic mean free of dirt or germs, not good for your body. A clean kitchen can still serve fried food. Skinny or thin are not synonyms at all, since body size and health are different things. Safe means low risk, which differs from nourishing; see the safe synonyms page for that idea.
Opposites, from slightly off to seriously ill
For people, unwell and under the weather are gentle, ill and sick are plain, and frail suggests weakness that lasts. For food or habits, use unhealthy, unwholesome or harmful, the strongest of the three (the harmful synonyms page has more).
- I felt unwell, so I left the party early.
- Skipping sleep every night is a harmful habit.
- The club was struggling until new members joined.
Phrases that do the job better
Sometimes a phrase beats a single adjective. In good shape, fit as a fiddle (playful, old-fashioned) and the picture of health all praise a person. Alive and kicking suits people, and also ideas that refuse to fade. For food, packed with goodness sounds friendly on a label. For a company, in good health or on a solid footing keeps the tone calm and professional.
Frequently asked questions
What is another word for healthy food?
Nutritious, wholesome and nourishing are the best choices. Nutritious sounds factual, while wholesome feels homely and warm.
Which formal words can replace healthy?
Robust works for people and economies, and healthful works for food or habits. Salubrious exists but is rare and can sound showy.
Can I say fit instead of healthy?
Yes, for people and animals. Fit stresses exercise and stamina, so it is the wrong word for food, plants or money.
What does a healthy amount mean?
It means a fairly large, sensible amount, as in a healthy appetite or a healthy bank balance. Substantial or generous can replace it.
Is unhealthy the only antonym of healthy?
Unhealthy is the direct opposite. For people you can also say ill, sick or unwell, and for food or habits harmful or unwholesome.
Is healthful a real word?
Yes. It means good for your health, as in a healthful climate. It is less common than healthy but is correct in formal writing.
