In this edition of Ask the Expert, John Bagnulo, PhD, Kripalu Healthy Living faculty, addresses questions on whether to eat or avoid common ingredients including fish, eggs, stevia, and whey.
The jury still seems out on the benefits vs. harm of eating fish. Based on the newest available evidence, what are the biggest risks, and do you recommend eating it at all?
I do advise people to eat fish. It offers nutrients that are more elusive in a vegan diet, without the health compromises that other sources of animal protein require you to make. I highly recommend sardines and mackerel as they are small, very clean, and packed with beneficial oils and trace minerals. They are on my top-five food list, in spite of being animals. I recommend that people avoid all big fish, especially large varieties of tuna and swordfish. These are tainted with PCBs, which I am much more concerned with than mercury.
Is there any harm in eating just egg whites (not the yolks)?
