Centenarian Food Composition Analysis

The long version of the original study is a PDF file, which is available here:

Here is a nice summary of it I found on some forum (since I can't copy and paste the PDF text):

I wasn't sure whether to post this as it is not low carb, but we are all looking for better health and centenarians don't get to their age without being in good health right? Some believe all carbs are pure evil, few believe that fiber is damaging to our health, and fewer still believe that vegetables are just poison!... Well the centenarians would disagree as they consumed an average of around 465g of them!

I figured that some of you might be interested in it at least... So here it is :thup:

A survey of the dietary nutritional composition of centenarians

To read the whole thing go here:


ObjectiveTo make a survey of the nutritional composition of the diets of centenarians.

Methods Thirty- four centenarians were selected as subjects. Retrospective surveys were made on the variety and amounts of food consumed and their nutritional composit ion. Physical examinations with laboratory tests such as cardiograms, ultrasoni c B rays, and blood, urine and hair tests were performed. Neutron activation te sting was done on hair content. The transmission turbidimetric method was used to measure apolipoprotein content.

Results The main food of the centenarians showed the characteristics of low calories, protein and fat but high fiber and mineral content. Laboratory results showed that the content of the elements of Cu, Se and Mn in hair was higher (P<0. 01) . Zn was normal. The apoA1/apoB100 ratio was higher than in the contro l group (P<0. 0I), and total cholesterol (TC) was lower than in the control group (P<0. 01).

Conclusions The variety of diet and its nutritional composition may be the main factors influencing not only the content of elements in body, but also the levels of apoA1 and apoB100, which may be helpful in preventing arteriosclerosis and forming and maintaining immunity. The diet of these centenarians might aid in preventing cardiovascular and cerebrovascular diseases and malignant tumors.

Some important parts:

- Diets were low in calories (1419k/cal), protein and fat, but high in fiber and minerals
- Vegetable intake was high
- -apoA1, apoB100, TC, HDL- C and LDL- C levels of centenarians are all lower than those of the control group
- It seems as though their healthy eating habits was the main reason for their longevity

and my fave

-the typical diet of Japanese centenarians shows sweet potato slices as their main staple food which is very similar to the diet of Chinese centenarians

I love my sweet potatoes! :hyper:

Here is something the poster left out: the Chromium level from the hair analysis was very low as well. It's interesting that even though chromium has been touted for its effect on blood sugar, it has also been shown to mutate mitochondrial DNA, which is the biggest no-no in longevity attainment, since mitochondria have not yet evolved a method for repairing its DNA. This is also why a methionine-restricted diet can be beneficial (perhaps contributing to why many centenarians seem to be vegetarianesque).

I love that sweet potato is a commonality between Japanese and Chinese centenarians. And look at the sheer quantity that they eat:
