How many times have you heard to eat lots of fruits, vegetables, whole grains, nuts, legumes (beans), and seeds? Study after study finds that eating a diet rich in these foods is linked to all sorts of health benefits. A big reason is that they have lots of fiber - which feeds beneficial microbes in our gut. A recently published review of studies in the prestigious journal Lancet examined studies done over the past 40 years and found numerous health benefits.

The researchers found that people consuming high levels of dietary fiber and whole grains have a lower risk of death from heart disease (cardiovascular mortality) and death from any cause. They also have a lower incidence of heart disease, stroke, type 2 diabetes, and colorectal cancer (as compared to those eating less fiber). There was a dose-response effect - in other words, the more fiber eaten daily, the lower the incidence of these diseases and deaths. They also found that a high fiber diet is also linked to lower cholesterol levels, lower weight, and lower blood pressure.

This study viewed 25 to 29 grams per day as a high fiber diet, but said the findings suggest that higher levels of fiber would be even more protective. Which means put down that delicious white bread and sugary cereal and start eating whole grain foods! Nowadays the average person eats less than 20 grams of fiber per day, but guidelines say to eat at least 30 grams per day. The researchers pointed out that getting fiber from real food is best.

From Science Daily: High intake of dietary fiber and whole grains associated with reduced risk of non-communicable diseases

People who eat higher levels of dietary fiber and whole grains have lower rates of non-communicable diseases compared with people who eat lesser amounts, while links for low glycaemic load and low glycaemic index diets are less clear. Observational studies and clinical trials conducted over nearly 40 years reveal the health benefits of eating at least 25g to 29g or more of dietary fiber a day, according to a series of systematic reviews and meta-analyses published in The Lancet.  ...continue reading "Eating Lots of Fiber Has Health Benefits"
