Secret of Health according to Islam: Healthy Eating Food Guide
Religion Islam is a complete way of life which encompasses all aspects of human life: spiritual as well as physical, personal as well as communal, physical health as well as material wealth, and religious matters as well as political issues. In Islam, our body and health are considered as important gifts of Almighty Allah (SWT). Imam Ali (pbuh) said: "Health is the best of blessings." In another narration, he says, "One of the blessings [of God] is the abundance of wealth; however, better than abundance of wealth is the health of the body." Imam Ja'far as-Sadiq (pbuh) said, "A believer who is physically strong is better than a weak believer." It is in this sense that our body is considered to be the trust given to us by Allah (SWT). And we have to safeguard and protect this trust.
Prophet of Islam, Muhammad (pbuh) said, Almighty Allah (SWT) did not create any illness without also creating the remedy, except death [old age].
Also Prophet of Islam, Muhammad (pbuh) has said that, the belly is the house of diseases, while dieting is the best of all medicines.
When advising his son Imam Hasan (pbuh), Imam Ali (pbuh) says: "Do not eat until you are hungry, and leave the table before you are fully satisfied."
Therefore, the basic Islamic guideline on food and drink is the rule of moderation. If we are moderate, then it does not matter what we eat or drink. (Of course, we are talking about Halal items only!)
O mankind! Eat the lawful and good things out of what is in the earth, and do not follow the footsteps of the Shaitan; surely he is your open enemy. (Holy Qur'an, 2:168)
Psychological effects of food: Scientists agree that food has both good and bad physical and psychological effects on us.
Imam Ja'far as-Sadiq (pbuh) said, Almighty Allah (SWT) only allowed some things for us to eat due to their good effects on us and forbade some things for us to eat or drink due to their ill effects.
Prophet of Islam, Muhammad (pbuh) said, "The prayers of whoever eats one bite of a forbidden meal shall not be accepted for forty days. Flesh grown from a forbidden meal deserves to be burnt in fire."
One of the important teachings of Islam is to refrain from obesity and becoming overweight. This can be accomplished by moderation in eating. And if one wants to lose weight, then that can be accomplished, from the religious point of view, by fasting.
We are familiar with the term Zakat, which means giving away a portion of our money in charity. In Islamic literature, they are different kinds of Zakats: Zakat al-Mal (charity with wealth), Zakat al-Ilm (charity with knowledge), and Zakat al-Badan (charity with body). The narrations say that the Zakat of body is fasting.
There are many sayings that encourage fasting (other than the month of Ramadan). "Fast and you will be healthy."
O Children of Adam! Wear your beautiful apparel at every time and place of prayer: eat and drink: But waste not by excess, for Allah loveth not the wasters. (Holy Qur'an, 7:31)
This is the most important advice for our health. Scientists have proved that the roots of many diseases lie in excess food and not eating healthy food.
Prophet of Islam, Muhammad (pbuh) said, "Do not spoil your hearts by overeating or overdrinking. The hearts die just as the cultivated land will when it is over-irrigated."
Similarly Imam Sajjad (pbuh) has instructed us to practice moderation. Under eating and hunger is also harmful. He writes in Risalat al-Huquq ("Charter of Rights"): "It is the right of your stomach that you should not turn it into a receptacle of what is unlawful, whether it is a little or a lot; and that you should not overeat, because that will turn eating into gluttony and shamelessness instead of giving you strength; and you should keep it under control when hungry or thirsty, because overeating (which sometimes ends even in diarrhea / dysentery) causes laziness, hinders from work, and cuts a man away from every goodness and nobility; and overdrinking (which ends sometimes into intoxication) makes a man look idiotic, ignorant and disgraced."
Once, Heraclius, Byzantine Emperor sent a few presents to Prophet of Islam, Muhammad (pbuh). One of these presents was a doctor. The doctor came to Prophet of Islam, Muhammad (pbuh) and said, "Sir, His Excellency sent me to serve you. I will examine your patients free of charge." Prophet of Islam, Muhammad (pbuh) accepted him. He (pbuh) ordered the Muslims to give him a home and it was carried out. Every day they brought him delicious food and drinks. Days, months passed, but no Muslim visited the doctor. Ashamed, the doctor came to Prophet of Islam, Muhammad (pbuh) and said, "Sir, I came here to serve you. Up to now, no patient has visited me. I have just sat idly, eating and drinking. Let me go back now."
Upon his request, Prophet of Islam, Muhammad (pbuh) smiled and said, "It is up to you! If you would like to stay longer, it is the first duty of a Muslim to serve a guest, to show honour to him. If you would like to go, good luck! Only, let it be known that nobody will visit you if you stay here for years, since my Ashab (companions) do not become sick! The religion of Islam has shown the way of how not to become sick. My Ashab (companions) are extra careful about being clean. They do not eat anything before getting hungry and they leave the meal table before becoming satiated with food."
It is seen that a Muslim, that is, he who obeys the commandments of Islam, does not suffer from illness. Those Muslims who suffer from illnesses are those who do not learn and carry out the commandments. Yes, the illness of death will come to everybody. This illness is a blessing upon Muslims. It is the herald of the voyage to the next world. It is an alarm for getting ready, repenting and saying one's last will. Allah (SWT) has rendered various diseases the causes of death. Everybody will catch a disease when the appointed time of death comes: Since there is death in the world, a headache is no more than a pretext.
