Research Shows: The sooner teens start, the greater the results... North American teens lack balanced nutrient intake. They often substitute junk food for wholesome foods. They dont get enough quality sleep. Their food choices are low in vitamins, minerals, fibre, etc. They spend less time at home. They skip meals. Their lifestyles swing between frenetically active and sedentary. Their need for independence challenges your attempts at creating balance. A Childrens Hospital and Harvard Medical School study found 42% of adolescent participants were vitamin D deficient, a condition that eventually leads to osteoporosis, and has been tied to multiple sclerosis, type 1 diabetes, rheumatoid arthritis, depression, auto-immune diseases and psychiatric disorders. Another Canadian-American study found that lower dietary intake of antioxidants (vitamins A, C, E and omega-3 fatty acids) can increase the risk of respiratory problems such as coughs, asthma and lung infections ... even relatively low levels of omega-3 fatty acids appear to protect teens from higher reported respiratory symptoms.
