BACKGROUND The role of dairy calcium intake and serum vitamin D concentrations in weight loss is controversial. OBJECTIVE The objective was to assess the association of dairy calcium intake and serum vitamin D with weight loss. DESIGN We analyzed data from participants in the 2-y Dietary Intervention Randomized Controlled Trial (DIRECT) [n = 322; mean body mass index (BMI; in kg/m²): 31; me...

Evidence from randomized controlled trials suggests that calcium may protect against recurrence of colorectal adenomas, which could lead to the subsequent prevention of cancer. Yet the trials used only a large single dose and were of small sizes, and thus, knowledge of the dose-response relationship and influence on high-risk adenomas is limited. To address these issues, we conducted linear and...

BACKGROUND Dietary calcium and vitamin D are essential for bone development. Apart from diet, physical activity may potentially improve and sustain bone health. OBJECTIVE To investigate the relationship between the dietary intake of calcium and vitamin D, physical activity, and bone mineral content (BMC) in 13-year-old Malaysian adolescents. DESIGN Cross-sectional. SETTING Selected public...

OBJECTIVE : To identify influences on type of milk consumed and the impact of milk choice on calcium intakes in Australian women of pre- and postmenopausal age. DESIGN AND SETTING : Questionnaires covering calcium intake, health-related dietary issues and priorities self-completed in a group setting. SUBJECTS : A total of 300 women recruited from community groups and government departments....

BACKGROUND AND PURPOSE No prospective studies have examined the association between calcium intake and the risk of cardiovascular disease in Japanese populations with a low mean calcium intake. METHODS Between 1988 and 1990, 110,792 Japanese subjects (46,465 men and 64,327 women) 40 to 79 years of age without a history of stroke, coronary heart disease, or cancer, completed a lifestyle questi...

Excess dietary proteins and "acid ash" diets have been suspected to increase the risk of osteoporosis, but experimental and epidemiological evidence is mixed. We aimed to determine whether the association between protein intake and the overall acid-base equilibrium of the diet (as renal net acid excretion [RNAE] estimate) and fracture risk vary according to calcium intake. During an average of ...

OBJECTIVE The purpose of this study was to prospectively examine the association between vitamin D and calcium intake and risk of type 2 diabetes. RESEARCH DESIGN AND METHODS In the Nurses' Health Study, we followed 83,779 women who had no history of diabetes, cardiovascular disease, or cancer at baseline for the development of type 2 diabetes. Vitamin D and calcium intake from diet and suppl...

Assessing calcium intake is necessary for epidemiological studies on osteoporosis. This study was aimed at developing a valid food frequency questionnaire (FFQ) to estimate the dietary calcium intake of Japanese people. The FFQ contains 26 items, representing common sources of calcium. The respondents, 74 women aged 15 - 79 years living in Fukui city, whose dietary calcium intake was estimated ...

BACKGROUND Colorectal cancer in Korea has become more prevalent over the few last decades, and calcium is considered a preventive factor for colorectal cancer development. We examined the associations between total and dietary calcium intake and the prevalence of colorectal adenoma in Korean adults. METHODS This cross-sectional study included 112 colorectal adenoma cases and 252 adenoma-free ...

Recommendations for daily calcium intake from dairy products are variable and based on local consensus. To investigate whether patients with a recent fracture complied with these recommendations, we quantified the daily dairy calcium intake including milk, milk drinks, pudding, yoghurt, and cheese in a Dutch cohort of fracture patients and compared outcomes with recent data of a healthy U.S. co...
