According to Doreen Virtue

For example, here are three foods which will instantly increase your Intuitive Clarity:

1. Fresh Pineapple: It’s the life-force energy in foods which increase our psychic energy. Pineapple has the highest life-force energy when it is sun-ripened. It goes right to the pineal gland (which is named for the pineapple because it’s shaped like the fruit) to increase your ability to visualize and have accurate visions.
2. Organic Broccoli: Broccoli is the winner of all foods that support endocrine glands associated with intuition. Just be sure it’s organic, as pesticide residue is an intuitive blocking agent.
3. Raw Organic Almonds: Besides the stress-reducing act of chewing on almonds, the boost of protein, Vitamin E, and calcium is gratefully absorbed by your endocrine glands and chakras, resulting in greater clarity with your intuition.
