使用する際の注意点

When a clearer distinction between the senses is required, the use of healthy may be reserved for describing the state of the object, while healthful may be used to describe its ability to impart health to the recipient. Vegetables in good condition are both healthy (i.e., not rotten or diseased) and healthful (i.e., they improve the eaters' health, compared to eating junk food). By contrast, a poisonous plant can be healthy, but it is not healthful to eat it. However, in informal speech, this distinction is not observed.
