"<p>I've experienced that raw carrots, finely grated and sprinkled with lemon juice, are not only a refreshing food but also calm the nerves, especially the nerves in the eyes. I have heard - but I have not personally experienced this - that one of the components of raw carrots, carotene, definitely strengthens the optic nerves and sometimes prevents blindness and clears incipient cataracts. This is possible, but not certain. What is certain is that raw, grated carrots, sprinkled with lemon juice and eaten with a meal or instead of a salad, are invigorating, refreshing, beneficial, and healing. It is also certain that it does no harm. In the same way, I can recommend unpeeled apples - one every day when it's the season - and a generous consumption of lemon and orange juice. I have noticed that in years when I have eaten plenty of raw carrots, lemon, and orange juice every day at the end of winter, I have not had colds or infectious diseases.</p>"
