Does anyone know where I can find the name or link to the study Ray references regarding the rabbits whose skin aged differently given their saturated and unsaturated diets? Thanks!

I didn't find Ray's, but here's a good link: Why Eating Polyunsaturated Fats Can Affect Your Skin - MDSUN Skin Care
I myself started using coconut oil and butter as my cooking oils years ago, and many people ask my age. I don't like to tell them, but I ask them how old they think I am, and they're usually off by at least 10 years younger. Heh, heh.

Some quotes from Peat.
In the l960s, Hartroft and Porta gave an elegant argument for decreasing the ratio of unsaturated oil to saturated oil in the diet (and thus in the tissues). They showed that the "age pigment" is produced in proportion to the ratio of oxidants to antioxidants, multiplied by the ratio of unsaturated oils to saturated oils. More recently, a variety of studies have demonstrated that ultraviolet light induces peroxidation in unsaturated fats, but not saturated fats, and that this occurs in the skin as well as in vitro. Rabbit experiments, and studies of humans, showed that the amount of unsaturated oil in the diet strongly affects the rate at which aged, wrinkled skin develops. The unsaturated fat in the skin is a major target for the aging and carcinogenic effects of ultraviolet light, though not necessarily the only one.
From Peat's article Coconut Oil
In Woody Allen's 1973 movie, Sleeper, the protagonist woke up after being frozen for 200 years, to find that saturated fats were health foods. At the time the movie was made, that had already been established (e.g., Hartroft and Porta, 1968 edition of Present Knowledge in Nutrition, who showed that adequate saturated fat in the diet helped to protect against the formation of lipofuscin).
From Peat's article The Great Fish Oil Experiment
Footnote 15 in Peat's article UnSaturated Vegtable Oils: Toxic
15. W. S. Hartroft and E. A. Porta, "Ceroid pigments," chapter VIII in Present Knowledge in Nutrition, 3rd Edition, Nutrition Foundation, N.Y., 1967.
