Food and the Law of Signatures

Have you guys heard of the Law of Signatures? It's somethign which I think most of us have received through email. The law states that the shape of the fruits and vegetables can somehow guide us into determining what we should be eating? How so? Read on to find out:

• Kidney Beans actually heal and help maintain kidney function and yes, they look exactly like the human kidneys.
• Egg Plant, Avocadoes and Pears target the health and function of the womb and cervix of the female - they look just like these organs. Today's research shows that when a woman eats 1 avocado a week, it balances hormones, sheds unwanted birth weight and prevents cervicle cancers. And how profound is this? .... it takes exactly 9 months to grow an Avocado from blossom to ripened fruit.
• A Walnut looks like a little brain, a left and right hemisphere, upper cerebrums and lower cerebelums. Even the wrinkles or folds are on the nut just like the neo-cortex. We now know that walnuts help develop over 3 dozen neuro-transmitters for brain function.
• Some observers have said that the figs look like the male genitals when two of them are hung together (apologies, don't mean to be crude!). Figs are full of seeds and the nutrients in them are said to increase the number of sperms to overcome male sterility. In many cultures throughout the world, figs are associated with fertility. They seem to act like nature's Cialis however unlike Cialis figs don't protect against Prostate Cancer
• A sliced Carrot looks like the human eye. The pupil, iris and radiating lines look just like the human eye...and YES science now shows that carrots greatly enhance blood flow to and function of the eyes.

I have received several variations of emails like these and while they sound so promising and wonderful but I have heard arguments against them as well. For example, it is apparently a misconception that carrots are good for the eyesight. One website claims that this was news spread by the British army to cover up a certain technology they had at that time that allows them to track things, so they just told people that they fed their army carrots that's why their eyesight are all excellent.

Figs on the other hand, don't appear on the list of things good for one's sexual organs. Soy, tofu, soymilk still top the list of food that promote prostate and sexual health in men. It has been said that these kinds of food lessen the need for cialis and viagra...figs have never been cited in medical journals.

I am now confused as to the veracity of the Law of Signatures. Do you guys think this is true?
