    About the issue of food and safety,
    people should treat it in a rational, objective and scientific way.
    Food is a necessary part of our life. We want a qualified life, we like
    all kinds of wonderful food. Food can give us energy, food have us feel
    life, food also let us learn to thankful. People have different life
    styles, some may like a cup of coffee in the morning, some may prefer
    some desserts in the afternoon. That's the life.

    Most of us like a
    glass of milk at night, for they want to have a good night. But, some
    people say there are so many additives in milk and they are bad for your
    health. Is that really? Milk contain a wealth of l-tryptophan, and
    l-tryptophan can be used to manufacture hormone 5-serotonin and
    melatonin. L-tryptophan can inhibit the brain activity so as to make
    people sleepy. However, the small amount tryptophan isn't enough to
    cause fluctuation of hormone levels in the body. In addition, the
    tryptophan in the milk to be transported to the brain probably not as
    easy as expected. In order to protect the fragile and important brain,
    the capillary structure of brain prevent a number of compounds in the
    blood go into the brain. That is the so-called blood-brain barrier. Any
    material that want you sleep peacefully must pass through the
    blood-brain barrier firstly. Tryptophan in milk mostly are powerless in
    front of the blood-brain barrier. So, drink a glass of milk at night
    does not play a significant role in sleep.

    In fact, use of food
    additives in processed food is almost inevitable. There are types of
    food additives you may not know. But do not be scared about it. You
    should make sure what are food additives. According to the definition of
    food additives, the most common food additives are bleaching agent,
    leavening agent, colorant, flavor enhancers, preservatives, spices, etc.
    Within national standards for use of food additives are harmless, and
    food safety incidents like formaldehyde, Sudan, or melamine are not food
    additives.

    In my opinion, food safety problems not only people
    should have an positive attitude toward them, but also strict rules need
    to be made to additives manufacturing. Buy regular factory products
    through the formal channels is the best means for consumers to protect
    themselves. There are so many suppliers around the world, choose
    reliable food additives suppliers is a guarantee to food safety.
