Music can evoke positive emotions, which in turn can lower stress levels. In a survey study, positive emotions were experienced more often and more intensively in connection with music listening. The more the participants liked the music, the less stress they experienced. To get the positive effects of music, you have to listen to music you like.

Health Alert: Slow Brain Growth In Babies Linked To Depression During Pregnancy!
Many women experience a roller coaster of emotions during pregnancy: stress, confusion, fear, sadness and depression. Babies whose mothers are depressed during pregnancy have a greater chance of growing slower, resulting in the head and body showing retarded growth. Also, antidepressants increase the risk of slow growth in the development of babies' brains.

Diet: High-Fat Diets Increase Colon Cancer Risk.
Eating too much fat and sugar puts a person at greater risk for colon cancer and obesity. In normal tissue from patients with colon cancer, they found that epigenetic marks on genes involved in breaking down carbohydrates, lipids and amino acids (abundant in the fatty Western diet) appeared to have been retrained. Epigenetic marks are chemical modifications that serve as on/off switches for many genes. These foods are changing the methylation patterns on a person's insulin genes so that they express differently, pumping out more insulin than the body requires.

Exercise: Exercise Linked To Change In DNA.
Exercise almost immediately alters DNA in healthy but inactive men and women. Although the genetic makeup is not altered, DNA molecules change structurally and chemically when a person exercises. One researcher noted, "Our muscles are really plastic. We often say 'You are what you eat.' Well, muscle adapts to what you do. If you don't use it, you lost it and this is one of the mechanisms that allow that to happen."

Wellness/Prevention: How Much Selenium?
While too much selenium may result in the development of type 2 diabetes, high selenium intake has been shown to protect against certain cancers, such as lung, colorectal, bladder, and prostate cancer. It also increases male fertility and has positive effects on antiviral function. Low selenium intake has been linked to memory and brain decline, low immune system quality, and a greater risk of death.
