Coconut oil the Super Food
Is it Right for Everyone?
Most people who think about healthy foods think about coconut oil. With the surge of interest you can now find it in every store. But the question most people should be asking is if it is right for everyone. FABP2 is a gene that is involved in fat absorption through the digestive tract by encoding for a protein that is crucial for the effective binding of fatty acids2. Some people have an allele that causes them to absorb certain types of fatty acids more easily, this variant is called Ala54Thr2,3,4. These people have a change in the common gene that causes an amino acid conversation to take place in the fatty acid binding protein there by increasing its binding affinity for both long chain saturated fats and unsaturated fatty acids by two-fold2,3,4. It is no surprise that a person with this genetic variation might struggle with maintaining a healthy BMI.
In the past, all foods containing saturated fatty acids were thought to be unhealthy, however research concerning coconut oil has shown that not all these fats contribute to disease. Research has shown that coconut oil contains mostly medium chain triglycerides (MCT) that are formed from fatty acids of chain length 8:0 to 14:05. MCT have been shown in research studies to decrease fat deposits in comparison to consumption of other fats. Because coconut oil contains mostly medium chain triglycerides, its absorption rate is not affected by the variant FABP2.
