“…This previous analysis, however, used a subjective estimate of percent density determined by an experienced radiologist. Other breast density studies have reported no associations for fruits (24), nuts and seeds (25), or cereals (24,25), and mixed findings regarding intake of vegetables (24,26), fish (24,26), dairy (24,27), and monounsaturated fatty acids or olive oil (27)(28)(29)(30) A Mediterranean diet effect may be more pronounced when quantified as an overall dietary pattern than when examined in terms of its specific components. Among current smokers in our sample, only three of the nine MDS components were statistically significantly associated with breast density, while six of the nine components were associated in the expected direction.…”

Mediterranean populations' lower breast cancer incidence has been attributed to a traditional Mediterranean diet, but few studies have quantified Mediterranean dietary pattern intake in relation to breast cancer. We examined the association of a Mediterranean diet scale (MDS) with mammographic breast density as a surrogate marker for breast cancer risk. Participants completed a dietary questionnaire and provided screening mammograms for breast density assessment using a computer-assisted method. Among 1,286 women, MDS was not clearly associated with percent density in multivariate linear regression analyses. Because of previous work suggesting dietary effects limited to smokers, we conducted stratified analyses and found MDS and percent density to be significantly, inversely associated among current smokers (β=−1.68, p=0.002), but not among non-smokers (β=−0.08, p=0.72) (p for interaction = 0.008). Our results confirm a previous suggestion that selected dietary patterns may be protective primarily in the presence of pro-carcinogenic compounds such as those found in tobacco smoke.

“…For example, when SFAs has been replaced with polyunsaturated fat, a reduction in low-density lipoprotein cholesterol and a reduction in coronary heart disease risk have been observed (Woodside et al, 2008); and postmenopausal women with an intake of SFAs 415% of total energy intake presented a 7% higher mammary density than postmenopausal women consuming o15% of SFAs of total energy intake (Nagata et al, 2005). The mechanism is not clear, but according with these studies, and in the same way, an excess in SFAs intake could also be linked to asthma.…”

Objectives: To study the relationship between lipid, fatty acid and lipid-rich food intake and current asthma in a group of Spanish schoolchildren. Subjects/Methods: The subjects of this cross-sectional study were 638 Spanish schoolchildren (8-13 years of age). The weight and height of all the subjects were recorded. A questionnaire, completed by the subjects' parents, was used to obtain personal and health information. Current asthma was established when the children had ever had asthma, if they had been diagnosed with asthma by a doctor and if they had been treated with medications at some time in the previous 12 months. Food intake was monitored using a 3-day food record. All foods consumed were converted into energy and nutrients. Results: The energy derived from lipids, saturated fatty acids (SFAs) and myristic and palmitic acids was independently associated with current asthma (Odds Ratio (OR) third tertile 2.85 (1.01-8.07) P ¼ 0.049, 10.00 (0.89-111.97) P ¼ 0.002, 11.21 (1.36-92.24) P ¼ 0.002, 7.58 (1.40-41.03) P ¼ 0.022, respectively), as was the intake of butter (OR third tertile 2.97 (1.01-8.68) P ¼ 0.001). No relationship was seen between this condition and the intake of any other fatty acid, the n-6/n-3 ratio, nor the consumption of margarine, milk products, fish, meat, eggs or vegetable oils. Conclusions: Increased intakes of SFAs, myristic and palmitic acids and butter seem to be related to the risk of current asthma in children.

“…Another [33] reported an inverse association between vegetable intake and breast density, but two others did not [32,34]. In nutrient-based analyses, several studies reported positive associations for total and saturated fat, protein, and alcohol intake [32,33,[35][36][37][38], and inverse associations for intake of fiber, carotenoids, calcium, and vitamin D [33,35,[39][40][41][42]. The generally inconsistent evidence for an association between diet and mammographic density in previous studies leaves open the possibility that mammographic density may not mediate dietary effects, if any, on breast cancer.…”

Objective Whether dietary patterns, rather than single foods or nutrients, are associated with breast density is not known. We investigated this in the Minnesota Breast Cancer Family Study. Methods Participants completed a 153-item food fre quency questionnaire and provided screening mammograms for breast density assessment using a computer-assisted method. We used multivariate linear regression to quantify dietary pattern-breast density associations. Results Among 3,147 women with dietary information, three dietary patterns emerged from principal components analysis: a fruit-vegetable-cereal pattern, a salad-sauce-pasta/ grain pattern, and a meat-starch pattern. Among 1,286 women with breast density estimates, the fruit-vegetable-cereal and salad-sauce-pasta/grain patterns were inversely
