I'm one of those people that take all these studies and surveys with a grain of salt (yes, yes, I know salt isn't good for you
I just think that if we all buy into this stuff we could go crazy. A few years ago "they" told us bacon causes cancer. We all had to stop drinking raw milk (people on dairy farms aren't even supposed to drink their own milk apparently), and on and on and on. The doctors put all our children on 2% milk so they wouldn't be overweight and then those same parents took their kids to McDonalds several times a week and guess what - the kids are overweight. The only milk in our house is Homogenized and we buy it from a dairy that doesn't put additives in it - same with whipping cream. Check the labels on your whipping cream and try to pronounce the ingredients. The stuff I get has the ingredients listed as: Cream & Milk. That's it!
I drink when I'm thirsty, I eat when I'm hungry. But, I don't eat processed food or quantities of junk food. I eat lots of veggies, fruit and some meat. I am 61 years old and still wear a size 4. I NEVER eat margarine - only butter. I cook with butter, I have 10% or 18% cream in my coffee and I like my coffee light so I use a lot. I also ingest white sugar (brown sugar is just white sugar with molasses) but in moderation. Other than the odd cold I am rarely sick. My hubby eats all the stuff I make and he is the same weight he was when we married - 175 at 6'.
He and I were having a discussion about these sorts of things the other night and we believe that because I don't cook with pre-packaged mixes and foods (I cook from scratch and it doesn't take me any longer to get a meal on the table than some folks that use pre-packaged stuff). I plan our meals so that if I want a good beef stew I'll make it the day before and let it simmer for several hours since we certainly don't want to wait several hours for dinner.
IMHO, if one eats quality food, doesn't go overboard on any one thing like sweets, sugar, salt, etc., then we'd have less obesity and more healthy people.
