When watching an old video about Weston A. Price he mentions tooth decay being linked to deficiencies in fat soluble vitamins from animal foods. The narrator lists the fat soluble vitamins: A, E, D, and F. Obviously I am a little confused normally I hear A, D3, E, K2 so I google vitamin F and apparently it is linoleic acid. To my knowledge linoleic acid is bad because it breaks in sunlight and causes sunburn and such, why would Dr. Price believe it is good for facial and dental development? Is it only good in small amounts from animal fats (or something of the like) or did he get this wrong? Pretty funny to see though...
