In plain words
We must not touch food that increases anger and vexation. That is precisely why in ancient times the ṛṣis who practised yoga kept the rules of food. They took only sāttvic food. If you take rājasic food, anger grows. If you take tāmasic food, sleep comes even while you are eating. We must give up these two and take sāttvic food. We must not eat too much chilli, too much salt or too much sourness. Not only that: before eating we must pray like this:
Brahman is the act of offering, Brahman the oblation, offered by Brahman into the fire that is Brahman; Brahman alone is reached by one absorbed in Brahman in every act.
Then Brahman answers from right within you:
Becoming Vaiśvānara, I dwell in the bodies of living beings; joined with prāṇa and apāna, I digest the four kinds of food.
“You simple fellow! In the form of Vaiśvānara I dwell right within you and digest the four kinds of food you eat,” He says. We must eat only food we are able to digest. We must never eat food that cannot be digested. We must be able to rise after the meal just as easily as we came and sat down to eat, lightly and happily. Some people sit down lightly when it is time to sit, but when it is time to get up they rise panting. That is not good. We must eat in moderation. These are Vināyaka's chief teachings. If you put these teachings into practice in your daily life, you too will become Vināyakas.
