"Chapter 25—Extremes in Diet Not all who profess to believe in dietetic reform are really reformers. With many persons the reform consists merely in discarding certain unwholesome foods. They do not understand clearly the principles of health, and their tables, still loaded with harmful dainties, are far from being an example of Christian temperance and moderation. MH 318"
"And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible."
This verse speaks of temperance in all things, which aligns with the idea of moderation in diet and avoiding extremes.
"Another class, in their desire to set a right example, go to the opposite extreme. Some are unable to obtain the most desirable foods, and, instead of using such things as would best supply the lack, they adopt an impoverished diet. Their food does not supply the elements needed to make good blood. Their health suffers, their usefulness is impaired, and their example tells against, rather than in favor of, reform in diet. MH 318.2"
"For bodily exercise profiteth little: but godliness is profitable unto all things, having promise of the life that now is, and of that which is to come."
This verse speaks to the value of bodily exercise, but also implies that neglecting the body through an 'impoverished diet' is not beneficial.
"Others think that since health requires a simple diet, there need be little care in the selection or the preparation of food. Some restrict themselves to a very meager diet, not having sufficient variety to supply the needs of the system, and they suffer in consequence. MH 318.3"
"Hast thou found honey? eat so much as is sufficient for thee, lest thou be filled therewith, and vomit it."
This verse warns against eating too much honey, suggesting that even good things can be harmful in excess, which parallels the idea that even a simple diet needs variety and balance.
