Hi all, on the recent brain-building and eating discussion, w-3 fats, and where to search them in the food have been discussed frequently ("eat brain or purslane"). I must say that I'm not much of a fatty-acid specialist. Consuming much of plant oils I wasn't too concerned about that up to now. Could someone well-informed - Todd that seems to be a homeplay for you- please help a little here for clearness? I know, that polyunsaturated fats are essential ("vitamin f"). You mentioned w-3 fats that must come from food (animal brains, sardines) or can be built from a plant-based predecessor. That sounds like vitamin-character too. To be able to look after that: What are the fat ty-acid's names in the USDA-Database ("ALA" ...)? They ought to be in human milk, if of importance for the growing brain, isn't it? I got for mothers milk: Lipids Fatty acids, saturated g 2.009 10:0 g 0.063 12:0 g 0.256 14:0 g 0.321 16:0 g 0.919 18:0 g 0.293 Fatty acids, monounsaturated g 1.658 16:1 g 0.129 18:1 g 1.475 20:1 g 0.040 Fatty acids, polyunsaturated g 0.497 18:2 g 0.374 18:3 g 0.052 20:4 g 0.026 Cholesterol mg 13.900 Which one is it, the w-3 source?? Any references on a RDA on one of these? Woul you recommend any net-available references on the importance of these? Thanks in advance for any informations on the topic regards Amadeus
