The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The author found that the interesterification processing procedure of fats may lead to heart disease.

There are two basic methods for producing interesterfied oil blends. The most common uses a chemical catalyst, such as sodium methoxide or ethoxide (dangerous and highly toxic industrial solvents), or hazardous metallic sodium or sodium-potassium alloy. The first three require heat of 80o C to 120oC to produce interesterified fatty acids. The product must then be neutralized (to remove the caustic catalyst), bleached (to get rid of the resultant dark brown color) and deodorized (a process which can actually introduce trans fats into the mix).

Another method uses enzymes to produce the interesterified fats. It is more expensive but results in less loss of oil through the formation of soaps, esters and mono- and di-glycerides.

Whichever method is used, rest assured that this is a highly industrialized process involving heat that begins with oils that have already been subjected to a highly industrialized process. The resulting product may be trans-free, but it will still contain chemical residues, hexanes and many dangerous breakdown products full of free radicals.
