The 3 basic nutrients are carbohydrates, proteins, and fats. Spiritually, they correspond to acts of kindness, prayer, and Torah study.
The Torah describes the most basic act of kindness as providing the poor with bread – carbohydrates.
The service of prayer, compared to that of animal sacrifice, requires great strength – proteins.
Generally speaking, saturated fats are bad for your health whereas unsaturated fats are good. Torah study which saturates your ego is bad.
Unsaturated fats are characterized as possessing double bonds. Learning Torah creates the double bond of Israel to the Torah to God.
In Hebrew, "fat" comes from the root meaning "oil." The Torah, especially its innermost dimension, is likened to pure olive oil.
