Omega 3’s during pregnancy and lactation | Dr Kristina Harris

Listen Now

In Episode #209, I sit down with Dr Kristina Harris Jackson to deep dive into the effects of omega-3 consumption on lactation and pregnancy.

“It’s much bigger than food when it comes to nutrition – it’s everything in your lifestyle.”

Dr Kristina Harris Jackson furthers The Proof’s exploration of omega-3s in this episode, offering her expertise in a discussion centred around maternal health. Nutrition during pregnancy can be a sensitive and confusing topic; when parents are trying to do everything they can to ensure optimal health outcomes, the abundance of available information is overwhelming. Today, Dr Harris Jackson provides some much-needed clarity and insight into omega-3s and pregnancy.

“Our bodies are very resilient. They are going to do everything they can to make baby as well as they can – it’s not a perfect world, it won’t always be perfect.”

With a PhD in Nutritional Sciences and an array of published papers, Dr Kristina Harris Jackson is extremely qualified to speak on today’s topic. She is the Director of Research at OmegaQuant Analytics, with a particular focus on omega-3s and maternal health. Here, Dr Harris Jackson helped create the Prenatal DHA test and the Mother’s Milk DHA test. If some of this sounds familiar, that’s because it is – in Episode #208, her father Dr Bill Harris appeared on the show to offer a wealth of knowledge on omega-3s and human health more generally.

In this episode, we cover a whole suite of information around omega-3s across early life stages. You will learn about the importance of nutritional biomarkers and exactly how important omega-3s are during pregnancy. We also discuss the potential effect of DHA on gestation length, inflammation during pregnancy, and how genetic variations may affect omega-3 conversion. Finally, Dr Harris Jackson shares supplementation guidelines, outcomes, and plant-based sources of omega-3s.

Specifically, we cover:
