Fruit and vegetable consumption, cigarette smoke, and leukocyte mitochondrial DNA copy number

Assessment of mitochondrial DNA copy number in peripheral blood leukocyte of opiate abusers and healthy individuals

Background: Based on the studies, variation in the mitochondrial DNA (mtDNA) copy number in peripheral blood leukocytes is associated with increased susceptibility to diseases including cancer. Opiate abusers are at high risk for diseases. In this study, we measured the mtDNA copy number in peripheral blood leukocytes in a group of opiate abusers compared with those in healthy individuals. Met...

Fruit and vegetable consumption.

OBJECTIVES This article focuses on associations between the frequency of fruit and vegetable consumption and other health-related behaviours or conditions, including physical activity, smoking, obesity and alcohol-dependence. DATA SOURCE The data are from the first half of cycle 1.1 of the Canadian Community Health Survey, collected from September 2000 through February 2001. ANALYTICAL TECH...

Low fruit and vegetable consumption

This analysis assessed the levels of mean dietary intakes of fruit and vegetables (excluding potatoes) measured in grams per day. The theoreticalminimum-risk distribution for fruit and vegetable intake was estimated to be 600g/day in adults, 480g/day in children aged 5–14 years, and 330g/day in children aged 0–4 years. It is proposed to use set intervals of 80g/day of fruit and vegetables (equi...

The Role of Fruit and Vegetable Consumption in Mental Health

Pre-diagnostic leukocyte mitochondrial DNA copy number and risk of lung cancer

We prospectively investigated the relationship between mtCN and the risk of lung cancer in 463 case-control pairs from two prospective cohort studies, the Nurses' Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS). The adjusted least-squares means of log-transformed mtCN (log_mtCN) by smoking status were estimated by generalized linear models. Multivariable conditional logis...
