I would really explore what is actually in those drinks before you give it to your son. Marketing can make it look like things are healthy and good when they really are not. There are a lot of hidden sugars in practically everything (even bread!), which have the unwanted side effect of lowering the immune system.
Another scary fact I have learned in the last year is that the American Heart Association, American Cancer society, American Lung assn. as well as several others, no longer reccomend the use of antioxidant vitamin supplements. Many vitamins are not bio-available, meaning your body does not absorb them. And in numerous other studies, vitamins have actually caused harm. One of the major problems is that there is no oversight in the vitamin industry. Companies are free to put in or leave out whatever they choose, as well as borrow research from anywhere they choose and apply it to their own product. Not very scrupulous, but legal.
About a year and a half ago a pediatric specialist reccomended a product called Juice Plus for my kids. Juice Plus is fruits, vegitables and grains in a capsule, chewable or gummy. It's not a vitamin (which are synthetic), it's actually food. The company grows all of their own produce, it's organic and vine ripened, and then it is superjuiced and dehydrated, preserving the nutritional essence. What is left is the nutrition from 17 different fruits, vegitables and grains. It comes to about 10 servings a day.
What is really unique about Juice Plus is all the independant research that has been done at major universities all over the world. Juice Plus studies have been published in many prestigious medical journals, such as the journal for the American College of Cardiology. Because of all the research, it's also been FDA analyzed numerous times.
After learning about all the research, and reading a lot about the state of nutrition in this country, I decided to dedicate myself to teaching others. I do wellness presentations in my home and educate people. It's very rewarding. Wether people decide to take Juice Plus, is their decision. In addition to understanding about Juice plus, I want people to take away a lot of information they can apply in their lives.
To learn more about Juice Plus, please visit my website, www.nutritionwithjennifer.com. Be sure to look under the Science of Juice plus tab. There is also another website you might find valuable, www.childrenshealthstudy.com. This is actually a non-profit informal health study. The famous Dr. Sears sits on the board. Juice Plus is dedicated to getting a million children on Juice Plus for free. Kids between the ages of 6 till the day before their 16th birthday are elligable. It's amazing to read about the impact of good nutrition on children. Let me know if you have any questions about all this.
All the best,
