Calcium Impairs Fat Absorption

Copenhagen, DenmarkIn a recent meta-analysis, researchers concluded that the more calcium included in the diet, the less fat will be absorbed.
The study, published in Obesity Reviews, compared the effect of calcium from dietary supplements or dairy products on the amount of fecal fat excreted.
The researchers estimate that an increase in daily dairy intake of 1,200 mg  can be expected to result in a 5.2 g per day increase in fecal fat excretion45 kcal per day, or 2 kg body weight over a year.
Although the effect was statistically significant, its importance for daily energy balance and body-weight regulation may be minor.
