SuppVersity - Nutrition and Exercise Science for Everyone

The good news is: Frying fish is not as bad as you may have thought it was. The oxylipin content even decreases. I won't tell you something you didn't know already when I quote from the introduction of a recent paper in Food Science and Nutrition  that "[s]tudies show that a decreased risk of cardiovascular disease (CVD) is correlated with a diet high in long-chain (LC) omega-3 (n-3) polyunsaturated fatty acids (PUFA)" (Flaskerud 2017)" and remind you that, outside of supplements, the primary dietary source of LCn-3 PUFA is fatty fish (Mori, 2014). Against that background, it is of paramount (health) importance that you don't damage the precious and oxidative not exactly stable DHA and EPA in your fish during the cooking/frying/baking process.

If you google images for food radiation, you get an idea of the (misplaced) prejudices against killing bacteria with ionizing radiation instead of nutrient damaging heat or potentially health-threatening chemicals -- No wonder companies still avoid it. You may remember that I asked you to send in questions/research topics for the new SuppVersity Kitchen Science  series in my recent article about different frying methods . Well, until now, the response has been - to be honest - disappointing. The first of the readers' suggestions I am going to address is Boban's question whether the (meanwhile) common practice of food irradiation is (a) sensible and (b) safe. Now, I have to admit that the irradiation doesn't take place in the kitchen. I do, however, consider the act of grocery shopping part of "kitchen science"; after all, the choices you make in the super- or at the farmers' market will significantly affect the outcome of your "kitchen sessions...

Air- or deep-frying, what's healthier? For most people that's not even a real question... rightly so?  "That's even a question?" I know, I know... With the health aura surrounding air frying it appears to be hilarious to even base a complete episode of SuppVersity | True or False  on the question whether air frying is in fact so much healthier than deep frying, but listen up: a recent study from the University of Porto  says that "most chemical parameters were similar on both frying processes, including [pro-carcinogenic]  acrylamide content" (Santos 2017). Can it really be that the air frying devices are another overhyped kitchen device you don't really need?

Within the fried fish category the study did unfortunately not distinguish between regularly fried (left) and breaded or otherwise crumbed fried fish. While this may be simply because they simply didn't have the data, it clearly reduces the practical value of the study. Sometimes, eating healthy can be more difficult than you'd think. Let's take your two weekly servings of fish as an example. With fish, there are the issues with nasty heavy metals and plastics in wild-caught and the increased omega-6 fatty acids in farmed fish that I've addressed at length in my 2013 and 2014 articles "Making the Right Fish Choices: Fatty Acid Contents of 33 Different Fish Species" ( read it ) and "Farmed vs. Wild-Caught: Pollutants and A Low Omega-3/6 Ratio" ( read it ). Unfortunately, it doesn't stop there. Whether or not you will see the full, if any health benefit you certainly will have heard of, will not just depend on making the right fish , but also...
