Diet Science Dee and Michael McCaffrey

A new study shows that a high-fat diet suppresses the expression of a protein called Jak3, which causes a cascade of inflammation that starts in the intestine, moves through the liver and on to the brain, ultimately causing Alzheimer's-like symptoms. Listen in this week as Dee discusses the results of this study and what it means for your health.References:Kumar, N., Mishra, J., Morales, R., & Kumar, P. (2024).

Glucagon-like peptide-1 (GLP-1) is a hormone naturally produced in the intestines during meals. It helps regulate blood sugar and weight by increasing insulin, slowing stomach emptying, and promoting fullness. Medications like Ozempic® and Wegovy® mimic the effects of GLP-1 but can be expensive and have unpleasant side effects. Listen in this week as Dee explores research on foods and probiotics that naturally boost GLP-1, offering similar benefits without the high costs and side effects.References:De Silva, A., & Bloom, S.

A study published in the British medical journal BMJ pooled data from 14 studies involving nearly 10 million people to look at connections between consumption of ultra-processed foods and various health outcomes. Listen in this week as Dee discusses the findings of this massive study and what it means for your health.Reference:Lane, M.

Gugulipid, also known as gum guggul, is an extract of the resin from a West Indian tree that has documented cholesterol lowering properties. Listen in this week as Dee discusses the specific compounds in gugulipid that decrease elevated cholesterol and triglycerides, and the proper way to take this effective supplement.References: Urizar, N.

In a recent study, researchers found that the diet of some ancient hunter-gatherers primarily ate plant foods, including beans and grains, with only a small percentage of meat in their diet. This new understanding contrasts with the meat-centric modern Paleo diet. Listen in this week as Dee discusses the findings of the study, and what it means for your health.References:Moubtahij, Z., McCormack, J., Bourgon, N., Trost, M., Sinet-Mathiot, V., Fuller, B.

HDL is an acronym for "high-density lipoproteins"--compounds made in the body that are considered the "good guys" in the cholesterol game. They help to keep the "bad cholesterol" from building up and forming plaque in the arteries. Having high levels of HDL reduces the risk for both heart disease and stroke. Listen in this week as Dee elevates your understanding of cholesterol and explores natural strategies to boost your HDL levels.References:Stadler, J. T., & Marsche, G. (2021).
