“…With respect to diet, several studies have found associations between a high consumption of low-fat dairy food, animal proteins, trans unsaturated fats, and carbohydrates, as well as high dietary glycemic load, and ovulatory infertility (5)(6)(7)(8). All these findings suggest that insulin and glucose metabolism may affect fertility.…”

“…From a macronutrient perspective, greater intake of carbohydrates in place of naturally occurring fats was associated with an increased risk of ovulatory infertility in a large cohort of married premenopausal women in the Nurses' Health Study (8). Among the same women, higher protein intake was associated with an increased risk of ovulatory infertility (7).…”

Objective: To investigate potential associations between dietary patterns (defined using factor analysis) and difficulty conceiving.Design: Case-control study nested in a Spanish cohort of university graduates (Seguimiento Universidad de Navarra [SUN] Project).Setting: Female university graduates all over Spain participating in the SUN Project. Patient(s):A total of 485 women, aged 20-45 years, reporting having presented with difficulty getting pregnant, and 1,669 age-matched controls who had at least one child. Intervention(s): None.Main Outcome Measure(s): Reported difficulty getting pregnant. Data were collected from baseline and follow-up questionnaires of the SUN Project.Results: Two dietary patterns were identified. They were labeled as "Mediterraneantype" and "Western-type" patterns. A lower risk of difficulty getting pregnant was apparent in the highest quartile of adherence to the Mediterranean-type pattern compared with the lowest quartile (odds ratio 0.56, 95% confidence interval 0.35-0.95).Greater adherence to the Western-type dietary pattern showed no association with this outcome. Conclusion:A greater adherence to the Mediterranean-type dietary pattern may enhance fertility. Further evidence about the relationship between this dietary pattern and fertility is needed to develop nutritional interventions for women desiring to get pregnant.2 Fertility and Sterility 2011;96:1149-1153 Dietary patterns and difficulty conceiving

“…Diets rich in foods with a high glycaemic index have been associated with an increased risk of diabetes [73], heart disease [74,75], and obesity [76,77], and there are ongoing studies linking diets with a high glycaemic index with age-related macular degeneration [78], ovulatory infertility [79], and colorectal cancer [80]. In this context, energy-restricted diets with a lower glycaemic index can improve energy adaptation during obesity treatment, favouring weight loss and improving lipid (total cholesterol and LDL cholesterol) and glycaemic (insulin and glucose) profiles [81].…”

The metabolic syndrome is a complex condition characterized by dyslipidaemia, high blood pressure, impaired glucose tolerance and abdominal fat accumulation. Subjects with the metabolic syndrome are at high risk of atherosclerosis and coronary heart disease. A comprehensive approach is required for patients suffering this cluster of clinical manifestations. Indeed, subjects with the metabolic syndrome could benefit from life-style modifications, particularly through exercise and diet. In this article, the evidence regarding the role of diet, in particular the role of food patterns based on the Mediterranean-style diet, in preventing and treating the metabolic syndrome are reviewed. Keywords Mediterranean diet · Metabolic syndrome · Diet IntroductionThere are many definitions of the metabolic syndrome, being still a matter of debate ( Table 1). The metabolic syndrome has its origins in 1923 when Kylin described a syndrome involving hypertension, hyperglycaemia and hyperuricaemia [1]. Later, Vague in 1947 linked abdominal obesity to metabolic abnormalities (i.e. diabetes, atherosclerosis, gout and calculi) [2]. In 1967, Avogaro et al. described six obese patients with diabetes, hypercholesterolaemia, and marked hypertriglyceridaemia, all of whom improved on a hypocaloric and low-carbohydrate diet [3]. In the 1970s, Phillips suggested associations of aging, obesity and sex hormone-associated clinical manifestations with heart disease [4,5]. In the late 1980s, Reaven proposed insulin resistance as the critical factor and coined the name syndrome-X [6].However, the most extensive definitions were established by the World Health Organization (WHO) and the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATPIII). In these definitions an enhanced cholesterol/high-density lipoprotein (HDL) ratio is considered a factor in the metabolic syndrome as well as elevated low-density lipoprotein cholesterol, atherogenic dyslipidaemia, insulin resistance, hypertension, abdominal obesity and elevated levels of several inflammatory markers [7,8]. In 2005 the International Diabetes Federation (IDF) emphasized abdominal obesity as the initiating factor in metabolic syndrome [9]. Although the definition of the metabolic syndrome makes little difference to prognosis [10,11], the IDF definition appears to be the most useful in clinical practice and considers different ethnic-related definitions of obesity.Each of the abnormalities promotes atherosclerosis independently, but the clustering of risk factors signifi- cantly reduces the quality of life [12] and increases the risk of cardiovascular morbidity and mortality. Indeed, the metabolic syndrome has been associated with an approximate twofold increased risk of cardiovascular morbidity and mortality in a European population [13]. The risk of cardiovascular morbidity and mortality is significantly higher among people with metabolic syndrome [14] even in the absence of baseline health conditions such as cardiovascular disease (CVD) and diabetes [15].The INTER...

У женщин с ожирением наблюдается увеличение концентра-ции С-реактивного белка в фолликулярной жидко-сти, что указывает на то, что метаболическая среда организма имеет прямое воздействие на процессы фолликулогенеза.…”
