Healthful, wholesome, salutary, salubrious, sanitary, hygienic.  (With this group contrast the Disease group below.)

The words of this group are assuredly blessed.  Every one of them has to do with the giving, promotion, or preservation of health.  But health is of various kinds, and therefore the words apply differently. Healthful is the most inclusive of them; it means that the thing it refers to is full of health for us. Wholesome also is a very broad term; what is wholesome is good for us physically, mentally, or morally. Salutary is confined to that which affects for good our moral (including civic and social) welfare, especially if it counteracts evil influences or propensities. Salubrious is confined to the physical; it is used almost solely of healthful air or climate. Sanitary and hygienic apply to physical well-being as promoted by the eradication of the causes for sickness, disease, or the like; sanitary, however, is used of measures and conditions affecting people in general, whereas hygienic connects itself with personal habits.

Assignment for further discrimination:  The word healthy is often confused with healthful.  You have already discriminated between these two terms, but you should renew your knowledge of the distinction between them.
