I saw that the family of Brother G need a great work done for them. H and I have gone to great lengths in this crime of self-abuse; especially is this true of H, who has gone so far in the practice of this sin that his intellect is affected, his eye-sight is weakened, and disease is fastening itself upon him. Satan has almost full control of this poor boy's mind, but his parents are not awake to see the evil and its results. His mind is debased, his conscience hardened, his moral sensibilities benumbed, and he will be a ready victim for evil associates to lead into sin and crime. Brother and Sister G, arouse yourselves, I beg of you. You have not received the light of health reform and acted upon it. If you had restricted your appetites you would have been saved much extra labor and expense; and, what is of vastly more consequence, you would have preserved to yourselves a better condition of physical health and a greater degree of intellectual strength to appreciate eternal truths; you…
"Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?"

Could you know just the nature of the meat you eat, could you see the animals when living from which the flesh is taken when dead, you would turn with loathing from your flesh meats. The very animals whose flesh you eat are frequently so diseased that, if left alone, they would die of themselves; but while the breath of life is in them, they are killed and brought to market. You take directly into your system humors and poison of the worst kind, and yet you realize it not. You love to indulge appetite. You have this lesson to learn: Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.” 2T 404.2"
"What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s."
The EGW passage directly relates the food choices to glorifying God, echoing the sentiment of 1 Corinthians 6:19-20 that our bodies are temples of the Holy Spirit and should be used to glorify God. The connection is clear and intentional.
