What are the four nutriments? Describe these nutriments.

Buddha said we feed our happiness or suffering with four nutriments: edible food, sense impressions, intention and consciousness. Not eating mindfully causes suffering, as well as smoking, drinking and toxins, which also affects our children. We absorb toxins through our sense impressions, especially through exposure to the media. Being mindful will help us know what we are "ingesting," and what poisons to avoid. We must also keep our intentions and volitions positive, and whatever we think will make us happy can often be obstacles to happiness. The fourth nutriment, consciousness, is composed of "all the seeds sown by our past actions and the past actions of our family and society.
