It's well known that obesity was declared a world health problem by the U.N. Dr. Robert Lustig was talking about what he considers something worse than obesity - kids that are more than obese because they are sick. He cites sugar as the reason. I haven't seen the movie, but sucrose being bad for you is far from new news.
He also talked about children drinking juice and that being a contributing factor to infants and toddlers being obese. I have seen programs that show obese infants and toddlers and realize that that's a problem. I had never seen that when my children were growing up. I did have a personal experience with juice with my first baby. My doctor who was ignorant about breast feeding told me that my baby was not getting enough calories because she was underweight so suggested that I supplement her diet with juice. She got diarrhea, so it was obviously bad for her. She stayed on the low side of normal for weight in spite of nursing strongly every 2 hrs., but it was because she was physically active - she kicked and moved a lot. What I remember also about the juice experience, though, was that she seemed to want the juice and not breast milk for a while after she was introduced to juice and it almost seemed like she had become addicted to it. Maybe that is what's happening today - mothers introduce juice too soon and then their babies demand juice by not accepting milk. If they give them what they want, they could get hooked on it. What a shame! NO JUICE FOR BABIES should be a simple message.
Dr. Lustig also seems to have coined the term "TOFI" for "thin outside and fat inside". Sugar is hurting children's liver even if they're not becoming fat. This reminded me of my recent research about low-carb diets.
My husband was given a diet that's very carbohydrate restrictive and he thought it was not a healthy diet - that it was based on bad science and he was skeptical. So I did some research. I found several sites on the topic, including studies on NIH and articles that referenced peer-reviewed studies. Low carb diets look pretty well proven to lose weight, lower cholesterol, reduce blood pressure, and lower blood sugar levels. This site reviews the studies and references some. However, the part of the diet that recommended no artificial sweeteners, my research showed that that may not necessary. It seems that its the psyche and habits of people who use artificial sweeteners that's more of the problem, but researchers indicate that better studies need to be done to determine the relationship between artificial sweetener intake and obesity. This report says artificial sweeteners can be beneficial in losing weight if used in moderation (as is best with all things). There's also not much risk of other health problems from them according to this report.
Of course, we need to remember to exercise, too. My doctor says 1/2 hr. minimum walking for my bone health to help calcium be properly absorbed is needed.
Good health to you!
