Poor nutrition leads to development of chronic diseases

Tuesday, 24 June 2014

International research involving the 成人大片 has shown for the first time that poor nutrition - including a lack of fruit, vegetables and whole grains - is associated with the development of multiple chronic diseases over time.

The results of the study, which looked at health, diet and lifestyle data of more than 1000 Chinese people over a five-year period, are published in this month's issue of the journal .

Researchers found that the proportion of those in the study with more than one chronic disease increased from 14% to 34% over the five years.

"Risk factors such as smoking, lack of physical activity and nutrition are already known to be linked to the development of chronic disease. But this is the first time research has shown that nutrition itself is directly associated with the development of multiple chronic diseases over time," says study co-author , from the 成人大片's .

"Those participants who ate more fresh fruit and vegetables, and more grains other than wheat and rice, had better health outcomes overall.

"Grains other than rice and wheat - such as oats, corn, sorghum, rye, barley, millet and quinoa - are less likely to be refined and are therefore likely to contain more dietary fibre. The benefits of whole grains are well known and include a reduction in cardiovascular disease, diabetes and colorectal cancer.

"Rice intake was significantly lower in the healthy group. This could be because rice is mainly refined and deprived of the benefits associated with fibres, and the kinds of phytochemicals that you find in whole grains," Dr Shi says.

He says the study highlights the role of micronutrients in protecting against disease. "A higher daily intake of iron, magnesium, phosphorous, vitamin C, potassium and vitamin B1 was associated with healthier participants," Dr Shi says.

"Based on our results, it seems that a higher intake of fruit helps to prevent against the onset of the first chronic disease, while a higher intake of vegetables helps to protect against developing more than one chronic disease.

"There is already a lot of general nutrition awareness among the population but this study reinforces the need for broad education programs about the benefits of healthy eating," Dr Shi says.

This study was conducted with colleagues at the Institut national de sant茅 publique du Qu茅bec, the Jiangsu Provincial Center for Disease Control and Prevention in Nanjing, China, Laval University, Universit茅 du Qu茅bec and Universit茅 de Montr茅al.
