According to a new study by Andrew Reynolds, PhD, Prof Jim Mann, DM, Prof John Cummings, MD, Nicola Winter, MDiet, Evelyn Mete, MDiet, Lisa Te Morenga, PhD it has been shown that more complex carbohydrates with higher fibre content, will lead to a longer life span. The glycemic index, however did not have an effect.
In the 135 million person-years of data from 185 prospective studies and 58 clinical trials with 4635 adult participants late found that dietary fiber intake is associated with substantial health benefits including lower all-cause mortality, while dietary glycemic index/load is not.
Fiber reduces mortality (RR 0·85), heart disease, diabetes, cancer… Greatest effect between 25-29 g/d.
“The complementary findings from prospective studies and clinical trials, which show that higher intakes of dietary fibre or whole grains are associated with a reduction in the risk of mortality and incidence of a wide range of non-communicable diseases and their risk factors, provide convincing evidence for nutrition recommendations to replace refined grains with whole grains and increase dietary fibre to at least 25–29 g per day, with additional benefits likely to accrue with greater intakes. Considering current evidence, dietary glycaemic index or glycaemic load might be less useful as overall measures of carbohydrate quality than dietary fibre and whole grain content.”
From this one can perhaps surmise that whilst using alternative sources of carbohydrates can be utilized, the importance of a higher fibre load is key for a longer life.
Replacing carbohydrates in diet with lower fibre source may thus be seen to possible lower your life span.
