salmon中的omega-3和walnut中的不一样，对健康跟有帮助。

“Omega-3 fatty acids come in more than one form. The types found in fish, called DHA and EPA, appear to have the strongest health benefits. Another form known as ALA is found in vegetable oils, flaxseed, walnuts, and dark leafy vegetables such as spinach. The body converts a small amount of ALA into EPA and DHA, and ALA also has some health benefits of its own.

But it’s best to avoid salty fish, such as smoked salmon."
