SUMMARY: Following the May 26 Treesdale seminar, you wanted to know practically how to improve microbiome health. You now understand it exists, it is changeable, and it is behind 70% of immunity. So here it is: attend the Salad and Dressings WorkShop in Wexford, PA! You know you have got to nourish your trillions of microbiome beasties and that certain fats are best till the dust settles on the other oils and their associations to disease. For those unable to attend, read the prebiotic and probiotic discussion in this post for tips for those two true microbiome supporting salad components. If you are local, come learn how to put it all together!
Summary: Learn the association between Soybean oil, Corn oil, Diabetes, Metabolic Syndrome & P-450 inhibition, the main liver detox enzyme, having significant affects on expression of genes that metabolize drugs & toxicants. Now is the time to be wary of and consider eliminating polyunsaturated fatty acids soybean oil and corn oil (as well as vegetable oil —since this typically contains soybean oil) as they were found to:
- Link to diabetes and metabolic syndrome. In the US, metabolic syndrome is estimated to be present in 20–30% of adults and 3–10% of children [100,101].
- Significantly affect the expression of many genes that metabolize drugs and other foreign compounds that enter the body, suggesting that a soybean oil-enriched diet could affect one’s response to drugs and environmental toxicants. The single most highly represented family of dysregulated genes was that of the [key liver detox] cytochrome P450 (Cyp) genes (30 genes total).
Also worth noting: the soybean plus fructose diet had less severe metabolic effects compared to the soybean oil diet, but it did cause more negative effects in the kidney and a marked increase in prolapsed rectums, a symptom of inflammatory bowel disease (IBD), which like obesity is on the rise.
SUMMARY: The focus of this post is to better your understanding of vegetable oils and unsaturated fats. Raw vegetable salads are chock-full of important vitamins and nutrients, but the latest science says you won’t get much benefit without eating them along with both the right type & amount of fat. In fact, essentially no or very low absorption of carotenoids was observed when salads with fat-free salad dressing were consumed (see this study or this study, Table 3.)
In this post learn: the preferred fat/oil for best carotenoid absorption, that you can actually ditch dressing and instead add half an avocado, or you can add cooked eggs to an incredibly small amount of dressing to even further boost carotenoid absorption. Make certain you consider the sections entitled What inhibits Carotenoid Absorption for possible impact due to your particular health status, and the tips for Decoding Labels.
