Would you believe that your diet can make a big difference in keeping a youthful appearance? It seems strange to think that the food we take in could result in fewer wrinkles. Wouldn’t it be better to put things on our skin rather than in our mouths?
Well, according to one scientific theory, our bodies start aging because of oxidation. This means the certain oxygen-containing molecules in our cells, called free radicals, have the capability to attach to and damage parts of our cells, including our DNA. Our bodies can repair this damage, but as we get older, these repair mechanisms start to break down, resulting in the signs of aging. Free radicals are actually reduced by our bodies, but their numbers can also increase because of the food we eat.
Besides avoiding foods which could potentially produce more free radicals, eating foods which contain certain vitamins and micro-nutrients can also contribute to keep us looking young. These vitamins help produce molecules called antioxidants, which actually help reduce the production of free radicals. Even better, foods containing antioxidants are not rare. Common antioxidants, like vitamins A and E, can be found in many dark-coloured vegetables. For example, carrots, seaweed, spinach, and broccoli are excellent sources of these helpful vitamins. Also, you can eat orange-coloured fruits like apricots and peaches. Vitamins A and E are particularly good for your skin remain young-looking. These nutrients strengthen your skin and make it soft. However, if you really want to stock up quickly on nutrients that benefit your skin, you should eat cow’s liver. One small piece of cooked cow’s liver contains twice as much A as half a cup of cooked carrots.
More recently, green tea has also been tentatively added to the list of youth-promoting substances. Although research about green tea’s effects on our bodies is at an early stage, scientists certainly believe that it is good for us. Scientists, however, are still cautious about predicting its capability to keep us looking youthful. But from recent experiments, its antioxidant properties seem to be able to repair cell damage already sustained as well as prevent damage in the future. In fact, green tea works even better if you apply it directly to your skin as an ingredient in facial cream.
"You are what you eat. " This old proverb certainly seems to be true the more we find out a-bout how our body works. Think about that the next time you sit down at the table.
