From a nutritional point of view
Everything we do to our food changes its subtle electrical reality, its electrical matrix and how it interfaces with our body. (Heistand and Coleman, 1999)
If we eat junk food, food that has been sprayed and preserved, food that has been flavored or frozen, these foods will have confusing energy that has been adulterated, and by eating these foods we will be developing faults in our network of energy. The results of such insults to over-eating and eating preserved foods are chronic fatigue, intestinal disorders, stomach ulcers, and so forth - all because of an electrically and chemically unstable stomach brought about by our improper ingestion of food or over-eating. Islam, therefore, has advised its followers to abstain from junk food (though the religion has not made these foods forbidden), sprayed and preserved foods, etc. - foods that are un-natural.

In Elixir of Love, one of the Shaykh Rajab Ali's devotees related about him that the Shaykh was once holding a session in one of his friends' house. Before starting his talk, he felt somehow weak due to hunger and asked for some bread. The householder brought him half a loaf of bread for him to eat, and then he started the meeting. The following night he said:
Last night I made salutations to the holy Imams (AS) but I did not see them. I pleaded to find the reason. I was told intuitively, You had half of that food and the hunger alleviated. Why then did you eat the other half! Having some food enough for body's need is all right, but extra to that would cause veil and darkness.
