During the last annual physical, I was shocked to test high in trans fat. I eat super healthy.

Upon investigation, I finally zoomed to a few boxes of very delicious oil-free, salt-free walnuts that a friend of mine sent to me. Once I get started with these walnuts, I could not stop. They are delicious and crispy. It would not take much time for me to consume a box. I knew I should not eat too much nuts at one time because its calories. However, my excuse was at least it's healthily cooked.

Well, as I dig deeper, I wondered why I am not so addicted to the home roasted raw walnuts. It does not taste that great. The meat is more oily (non-crispy) and bitter. I suddenly realized that to make the delicious nuts crispy, the manufacturer has to put the nuts through high temperature drying process. Oils, especially polyunsaturated oils may oxidize and hydrogenate under really high temperatures.

So be careful about oils (such as nuts) under high temperature.

Indeed, nature makes foods that naturally limit your appetite. Human learned to process delicious unhealthy foods that can greatly increase your appetite.
