This study examined the effect of the level of dietary intake of medium-chain triglycerides (MCTs) on their energy value. The MCT oil tested for the purpose replaced baker's shortening in a traditional muffin formula and provided, through muffins added to the diet of the rats, 20 or 30% of total energy. Changes in body composition of the rats due to MCTs fed over a three-week period formed the basis of calculating energy value. Rats fed MCTs deposited significantly (P < 0.05) less fat in their carcasses than did rats fed shortening. Calculations showed the MCT oil tested to contained 7.0 cal/g at both levels (20 and 30%) of energy intake, In an earlier study, this MCT showed an energy value of 6.8 cal/g when fed at a 40% energy level. Thus, the level of feeding MCTs, unless quite excessive, may have a limited effect on the energy level of MCTs, which appears to be about one-fourth lower than that of conventional fats.
