articles basically say no beneficial evidence for healthy adults,apart from the cod liver oil (and Korean Ginseng good for erectile dysfunction).
Your diet it pretty good. Fruit, nuts and seeds, yoghurt, vegetables and carbohydrates, pretty good start. Making your own soup is really easy (I have just started). I got a hand blender for £15 off AMazon, you just then need to boil veg a bit, add an onion,garlic, spices, or whatever takes your fancy and some stock if necessary. Then blitz away. Quick and nutricious. Also good way to sneak in veg you don't particularly like, but can hide them. For instance I think spinach is boring and gritty, but you can drop a handful in to the soup and blend it and you have the nutrition without the yuckiness. Also frozen and canned veg is very nutritious, cheaper and easier to store. I'm not advocating not buying any fresh, but pointless if it doesn't get eaten.
Houmous also easy to make and nutritious protein wise, home made means you can control unnecessary fat. Could add some raw veg to houmous and pitta. Make past whole grain for added nutrition and keeps you fuller longer. For bought soup and bread, check the salt levels, as often they have far higher than you would expect (or want!).
Might want to consider some dark green veg as an addition to your good work and check you're getting a good source of protein.
Keep up the good work :o)
