Is Fish the Food of Love, and Babies?

I always knew fish were good for you in general, but didn't realize that they could be of use in conceiving babies! However, fishes like salmon which are known to be healthy with various nutritional values, are expensive. I love salmon, but sometimes it can be a burden for students like me. Through research, I found some information that allows you to compare and purchase salmon and other types of fishes. https://www.tridge.com/intelligences/salmon

Weird to see the term”lovemaking” in a scientific article. Maybe love is not necessarily involved, you know?

It seems that most of the baby making merit coming from fish is actually coming from selenium(Se), an important nutrient from ocean fish and shell fish. "Selenium (Se)–vitamin E supplementation in infertile men: effects on semen parameters and pregnancy rate" (Conclusions) Supplemental Se and vitamin E may improve semen quality and have beneficial and protective effects, especially on sperm motility. We advocate their use for the treatment of idiopathic male infertility diagnosed with asthenoteratospermia or asthenospermia in semen analysis. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3048346/ "The selenium status of women with a history of recurrent miscarriage." (Conclusion) There was evidence of selenium deficiency in women with recurrent miscarriages compared with a control group of women with a good reproductive performance. This difference was seen in hair samples but not serum samples and therefore may not represent a simple nutritional deficiency. https://www.ncbi.nlm.nih.gov/pubmed/11702843

Mr. Bakalar - Before publishing in the print edition, please double-check your reporting. It does not appear to agree with the paper’s abstract and it makes a huge difference. Your report: “They found that men who had two or more four-ounce servings of fish a week had a 47 percent shorter time to pregnancy, and women a 60 percent shorter time, than those who ate one or fewer servings a week.” But the report’s abstract: “Couples where the male and female partners consumed ≥8 seafood servings/cycle had 47% and 60% higher fecundity (shorter TTP) compared to couples with male and female partners who consumed ≤1 seafood serving/cycle, respectively.” See https://academic.oup.com/jcem/advance-article-abstract/doi/10.1210/jc.20... There is a big difference between “two or more four-ounce servings of fish a week” versus “one or fewer servings a week” and between “≥8 seafood servings/cycle” and “≤1 seafood serving/cycle.” The paper recites at least an 8-times difference in consumption, and likely more, while you report only a 2-times difference. Which is it? The numbers matter a lot. (And studies like this usually report differences between extremes... And if we are talking such extremes, what is the whole list of "factors" controlled for?) P.S. Once pregnant or nursing, women need to COMPLETELY avoid high-mercury fish, large, long-lived fish like tuna, shark, swordfish, etc. Really, they really, really do. (But shrimp and quick-growing fish like catfish are OK…)

And Mr. Bakalar didn’t mention any of the previous studies showing harmful effects of shellfish consumption on fertility. The present study didn’t separate out shellfish from other kinds of fish. I think more context is needed here. Why base health recommendations on just one study? I would have expected better reporting from the NYT.

You want to leave some room for dessert.

Maybe, but I hate the taste of fish and other seafood, so I guess I'll never know.

Marine-sourced foods are now contaminated with a variety of potentially toxic substances, including plastics, microbeads, nanoparticles, synthetic organics, and radionuclides. Pregnancy and fish may not be a good combination.
The Pooch (Wendell, MA)
@RC: All of these are potential problems, but the health benefits of the nutrition in fish and shellfish still outweigh the possible risks. We have to eat something.
JB (FL)
I'm with you, RC! The data coming out about microplastics in the ocean and marine life are scary. I love seafood and I love catching it myself out in the ocean as it feels a bit "safer" (falsely so, I'm sure), but I still worry about the risk. But alas, I do not live a life where this is even possible on a weekly basis.

OK. The pomegranate, red wine, dark chocolate, and coffee industries have had their turn. Now it's time for the fishing industry to cast their line. Just "Eat food, not too much, mostly plants".

Ignorance on fish mercury is incredibly bad in health talk. As some of the scientists, for example in the attached website, explains how fish with rich in selenium detoxify mercury in order to avoid damage from mercury. https://www.montereyfish.com/mercury-and-selenium/ If we eat fish and shell fish, we can get necessary selenium for detoxification of heavy metals like mercury. Sulfur does same detoxification as selenium. Eggs and cruciferous vegetables such as cauliflower, cabbage, garden cress, bok choy, broccoli, Brussels sprouts and similar green leaf vegetables are good source of sulfur. Dr. Valter Longo of University of Southern California, an Italian-American biogerontologist and cell biologist known for his studies on the role of fasting and nutrient response genes on cellular protection aging and diseases, recommends fish, particularly for older people, because it is the best animal protein source for longevity.

Dr. Lisa Mosconi of Associate Director of the Alzheimer’s Prevention Clinic at Weill Cornell Medical College (WCMC)/NewYork-Presbyterian Hospital & an Associate Professor of Neuroscience in Neurology also recommends the same low-mercury, high omega-three Monterey Bay approved fish 2-3 x a week for brain health, just like Dr. Valter Longo.

Selenium is not as healthy as you think! Recent studies have linked it to cancer. There is a sweet spot for intake and selenium species might matter. https://www.ncbi.nlm.nih.gov/m/pubmed/29376219/

Elemental selenium and most of the selenium containing proteins except selenomethionine should be taken cautiously. However we usually intake safe selenomethionine from fish. Selenium is also an important nutrient for the thyroid problem treatment.
