@Ragman,
Almond oil is popular, but I usually avoid it. Here's the reason: I just found out I am slightly allergic to vegetables of the Nightshade family. These are South American vegetables, and include, besides tobacco, Tomatoes, Potatoes, (sweet potatoes are a different family and not Nightshade), and Green and Red Peppers, (not peppercorns). I cut them out and found out my digestion improved a bit. I can have them now and then, even for a week or two, but if I have a steady diet of them eventually I'll feel an effect.
One thing to understand is that Nightshade vegetable all used to be poisonous, but the Native Americans down in South America bred out the poison, and these vegetables feed a good portion of the world now. After my experience with Nightshade veggies, I decided that I didn't want to use any food that once was poisonous but the poison has been bred out of it. Because in most cases, the poison has not been completely bred out, it has just been reduced to the point that it doesn't bother most people. When it reaches that point, then they stop trying to breed the rest of the poison out and start breeding for resistance to pests and other things.
Almonds used to be poisonous, but again, the poison has been bred out. Or bred down. Since there are alternatives to almond oil, I use the alternatives which are as good or better. Just a personal thing, but I thought I would relate it.
Here's a list of the densities of oils, the lower the better. Almond is fairly low, grapeseed is one of the lowest. The list is on pages 26 & 27 of the pdf. Different color text means they got the number from a different study-but most studies are fairly consistent.
