However, the underlying mechanisms are not understood. 10 subjects participated in a randomized crossover study of three isocaloric 1-week diets with: low calcium and normal protein (LC/NP: 500 mg calcium, 15% of energy (E%) from protein), high calcium and normal protein (HC/NP: 1800 mg calcium, 15E% protein), and high calcium and high protein (HC/HP: 1800 mg calcium, 23E% protein). RESULTS: The calcium intake had no effect on 24-h EE or fat oxidation, but fecal fat excretion increased approximately 2.5-fold during the HC/NP diet compared with the LC/NP and the HC/HP diets (14.2 vs 6.0 and 5.9 g/day; P < 0.05). The HC/NP diet also increased fecal energy excretion as compared with the LC/NP and the HC/HP diets (1045 vs 684 and 668 kJ/day; P < 0.05). There were no effects on blood cholesterol, free fatty acids, triacylglycerol, insulin, leptin, or thyroid hormones. CONCLUSIONS: A short-term increase in dietary calcium intake, together with a normal protein intake, increased fecal fat and energy excretion by approximately 350 calories per day. This observation may contribute to explain why a high-calcium diet produces weight loss, and it suggests that an interaction with dietary protein level may be important.
We put Cox proportional perils models, with age due to the fact hidden go out metric, so you can guess danger of colorectal cancers
2005 Learn from Calcium supplements Faster Colorectal Malignant tumors: Calcium supplements out of diet and drugs was regarding the smaller witryna mobilna sudy danger of colorectal cancer tumors in the a prospective cohort of women
We investigated the association between calcium intake and colorectal cancer in a prospective cohort of 45,354 women without a history of colorectal cancer who successfully completed a 62-item National Cancer Institute/Block food-frequency questionnaire. Women were followed for an average of 8.5 years, during which time 482 subjects developed colorectal cancer. For increasing categories of calcium from supplements, the risk ratios (and 95% CI) relative to no supplement use were 1.08 (0.87-1.34), 0.96 (0.70-1.32), and 0.76 (0.56-1.02), P(trend) = 0.09. Simultaneously high consumption of calcium from diet and calcium from supplements resulted in even further risk reduction, RR = 0.54 (95% CI, 0.37-0.79) compared with low consumption of both sources of calcium. These data indicate that a difference of < 400 to > 800 mg of calcium per day was associated with an approximately 25% reduction in risk of colorectal cancer, and this reduction in risk occurred regardless of the source of the calcium (i.e., diet or supplements)
Fat reduction pursuing the enhanced proteins diets was associated with of use metabolic consequences that are not affected by protein source
Effectation of calcium supplements and you will dairy food inside the high-protein, energy-restricted diets on the weight loss and you can metabolic variables when you look at the obese adults.
OBJECTIVE: Evaluate the results two-high-protein (HP) diets one differ inside the weight-loss calcium supplements and you will proteins source towards the pounds loss, system composition, glucose and you can lipid k-calorie burning, indicators regarding the liver setting, fibrinolysis and you can endothelial setting and you will blood pressure level. DESIGN:: Randomized, parallel research (several wk of your energy restrict, cuatro wk of energy equilibrium) regarding higher dairy healthy protein/high-calcium supplements (DP, 2400 milligrams Ca/d) and high blended healthy protein/modest calcium (MP, five-hundred mg California/d) dieting (5.5 MJ/d, 34% proteins, 41% carbs, 24% fat). SUBJECTS:: In every, 50 suit, heavy (many years 25-64 y; body mass index twenty-five-thirty-five kg/m(2);) people (n=20) and you may female (n=30). RESULTS:: Death of total weight (-nine.7+/-step 3.8 kilogram), weight mass (-8.3+/-0.cuatro kg) and you can slim bulk (-step one.6+/-0.step three kg) was basically separate away from weight reduction class. Developments from inside the accelerated insulin, lipids, systolic/diastolic blood pressure levels, and you can markers out-of the liver means, fibrinolysis and you can endothelial setting was in fact independent of weight loss intervention. CONCLUSIONS:: Enhanced weight loss calcium supplements/dairy products for the an electrical power-minimal, Hp diet will not apply to weight reduction or system structure.
