Sardine fishes have high omega 3 which reduces inflammation in the body - I have been giving my dog sardine fishes (not the prepacked ones) , Salmon and Cod fish to reduce toxicity and I can see how much more hyper and healthier he is. My mom is also big on fish oil and sees significant improvements on health, i think you both are the same age. Fish oil and seed oil have very diff impact on the body. With seed oil, it also depends on what types of seeds and if you are consuming it directly or processed.
