Raw Living's sunflower seeds are from Europe (Hungary). They are guaranteed raw. We have used sunflower seeds personally, and in our Sunseeds mix, for years, and we have often found it difficult to find truly raw seeds - even from sources that have promised they are not heat-treated.
Sunflower seeds, or more accurately, sunflower kernels, are a source of vitamins and minerals, phytosterols, and fibre. They contain anti-oxidants thanks to the presence of vitamins E and C, and antioxidants deal with the free radicals that can lead to the development of disease. They are high in linoleic acid (an essential fatty acid), some amino acids e.g. tryptophan, Vitamin B (especially thiomine, pantothenic acid, and folate) They have very high phytosterol content - phytosterols help reduce cholesterol, and the fibre is great for the digestive system.
Sunflower seeds are also high in unsaturated fats, the good fats that may protect the heart.
