chicken soup has not been studied very rigorously in groups of sick or healthy people, but one group of researchers did carefully investigate the impact of chicken soup on the specific cells of the immune system that increase inflammation when you have an infection. When you have an infection, immune cells called neutrophils migrate to the area to help fight the infection. One of the things those neutrophils do is release chemicals that increase the amount of inflammation going on in your body. This inflammation is part of why you develop more mucus and phlegm when you have a cold. Though some of the inflammation response helps to fight off infection, other aspects of inflammation make you feel lousy.
    Scientists studied whether chicken soup had an impact on the inflammation response. The scientists studied a homemade chicken soup, as well as commercially prepared soups, to determine whether chicken soup prevented the inflammatory cells from migrating or moving to the source of infection. Amazingly enough, chicken soup worked! Various dilutions of the homemade soup and the majority of the store-bought soups inhibited the movement of the neutrophil cells, which might give chicken soup anti-inflammatory properties.
    Chicken soup is not proven to be an effective cold remedy, but it does have some properties that might help you feel a bit better. You may also experience the best kind of placebo effect from chicken soup. Having soup prepared for you by a loved one, or associating chicken soup with memories of someone taking good care of you, may play a powerful role in how much better chicken soup helps you to feel. Chicken soup is not the cure for the common cold, but the science suggests that it may be worthwhile to listen to Grandma on this one. You just might feel a bit better.

Chocolate
    Chocolate or fried foods cause acne
    Those of us with acne will try almost anything to improve our skin. Everyone wants clear skin. When you have pimples popping up all over, your parents and other well-meaning people often tell you to avoid chocolate or fried foods because these foods make acne worse. Many acne sufferers swear that they see differences in how bad their acne is based on what they eat. Whether or not your diet will sabotage your efforts to have clear skin is a question addressed by some interesting science.
    Studies show us that people around the world believe that there is some link between acne and what they eat. The belief that particular foods make acne worse has been reported in studies of acne sufferers and their families from countries ranging from Greece to Britain to Jordan. Greasy food is most often reported as a cause of acne, perhaps reflecting beliefs that greasy skin and eating greasy food are linked. Nonmedical people are not the only ones who are not sure what makes acne better or worse; medical students, nurses, and family practice doctors have also been shown to have very limited knowledge about what worsens acne and what works to treat it.
    The science about acne and what we eat is actually rather tricky to sort through. A number of studies have looked at how many people suffer from acne in different parts of the world. These studies find that acne is more common among adolescents in places like the United States and Canada than it is in certain parts of Africa or in other isolated places, like Papua New Guinea or among certain groups in Paraguay or Brazil. The low rates of acne in places where people are eating very different foods than we do in America make scientists wonder whether your diet really does make a difference for your acne. People in America and Canada do eat more chocolate and more fried, greasy foods than people in these other places. The problem with these studies is that other factors could also be making a difference in the rates of acne. Certain ethnic groups might just be less prone to developing acne. Or other factors related to the environment or skin care practices might play a role.
