Are Ape Diets Suited To Humans? For relative sizes of small and large intestine in apes and humans.
How Many Minutes A Day Do You Spend Eating (Chewing)? Apes take 6 hours/day to eat 1800 calories of raw food.
Thank you. I kept trying to remember where I had previously read about this study when it came out. I was going to mention it on your last post.
"Some had difficulty finishing it."
You know, most people can kill a 500-600 cal. burger with little effort and still have room for fries. Give someone the same amount of calories in raw fruits and vegetables, and I bet they would struggle to finish it in one sitting. Do you think this has something to do with the obesity problem? Maybe our bodies were designed to eat foods that filled us up much quicker than the processed foods so predominate today? We don't even have to discuss the nutritional value etc. . .
caulfieldkid.. sure, our bodies are definitely designed to eat foods that fill us up quicker than processed foods. It's no argument processed foods are bad for us (or at least, not positive).
My notice with this diet is it's high in fiber and carbohydrates, but low in protein (aside from the nuts). I haven't gotten to the protein part in my Nutrition course (it's coming up next), but don't we *need* protein? (No, I don't agree with a strictly vegetarian diet). Please correct me if I'm wrong.
Perovskia, we definitely need protein but don't forget that fruits, vegies and nuts all contain protein (small amounts, sure) and fish was included in the diet in the 2nd week which would boost the protein level dramatically.
I agree with Duyvken, plant foods have a lot of protein. I'll post some thoughts, although anyone can chime in.
I've been reading about diets of the great apes. Fascinating. Maybe I'll post more about that too.
Right, I forgot about the fish.
I'm not used to plants having a lot of protein (that's not the way society has 'conditioned' me). Hopefully with more reading though, I'll find otherwise.
How did their blood sugar do?
I asked that about the blood sugar b/c, A) it's a concern of mine (as you know); and B) I am curious if all the fruit in the diet had an impact on it.
I don't know, Melinda. The info I saw on the experiment didn't say.
My suspicion is that fasting blood glucose declined ... because weight declined. (Weight loss is associated with improved blood glucose control.) That doesn't inform on the effect of the fruit though.
Another reason I suspect it declined is the low fat in the diet. Fat in the diet is linked to insulin resistance. See:
"Dietary fat has been implicated in the development of insulin resistance in both animals and humans. Most, although not all, studies suggest that higher levels of total fat in the diet result in greater whole-body insulin resistance. Although, in practice, obesity may complicate the relationship between fat intake and insulin resistance, clinical trials demonstrate that high levels of dietary fat can impair insulin sensitivity independent of body weight changes. In addition, it appears that different types of fat have different effects on insulin action. Saturated and certain monounsaturated fats have been implicated in causing insulin resistance, whereas polyunsaturated and omega-3 fatty acids largely do not appear to have adverse effects on insulin action. Given the importance of insulin resistance in the development of diabetes and heart disease, establishing appropriate levels of fat in the diet is an important clinical goal."
And some evidence, from that May issue of the Am J Clin Nutr I blogged about:
"a low-fat vegan diet appeared to improve glycemia and plasma lipids more than did conventional diabetes diet recommendations"
Thanks for the info Bix! Very helpful!
Wow nice post..
Thanks that's very useful
