Some people understand the importance of a good diet as far as long-term health. Others do not. Most of the others don’t care sufficiently enough to make any changes. While trying to get someone to eat more spinach and lentils, it will probably be both obnoxious and probably futile to present them with supplements that may support their health. It can be tough to convince them that you are concerned enough for their well-being to make the necessary effort. This may be especially helpful if they happen to be suffering from a medical condition, or are in poor health generally.
