She pointed out that, unlike the prevailing wisdom we have been told the last few years, fats are not always bad for you and fiber is not always good. The principal source of these fatty acids is fish oil, but preparation of the fish oil is somewhat tricky because mincing the fish results in rapid oxidation of the oil, which ruins its benefits. Apparently some fish oil capsules are prepared without mincing the fish and also have added anti-oxidants so that they are beneficial to take. Of course, another way to get your fish oil is to go eat a fish.
Dietary fiber comes in two varieties, water soluble and water insoluble.
Oats, guar gum, and pectin are water soluble. Eating them reduces the glycemic index of your meal, which is generally considered good, and reduces the LDL cholesterol, but also slows down the movement of the food through your intestine, resulting in increased fermentation and increasing your risk of colon cancer. Thus, your choice of fiber depends on how you want to balance your risks. Vitrification is the process of cooling to a glassy, but not crystalized, state. This is important because successfully vitrifying and thawing a complete organ is much more difficult than doing so for isolated cells.
