Diet Science Dee and Michael McCaffrey

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).

Bergamot, a citrus fruit hailing from the groves of southern Italy’s Calabria region, has been shown in clinical trials to lower bad cholesterol and triglycerides, and increase good cholesterol. Listen in in this week as Dee discusses the results of clinical studies using bergamot and the virtues of this super fruit.Reference:Lamiquiz-Moneo, I., Giné-González, J., Alisente, S., Bea, A.

In 2015 a research team at UC Riverside found that soybean oil consumption induces obesity, diabetes, insulin resistance, and fatty liver in mice. Now, a new study by the same team shows that oil could also affect genes in the brain related to conditions like autism, Alzheimer's disease, anxiety, and depression. Listen in this week as Dee discusses the details of this study and how the changes in microbiome caused by soybean oil consumption are linked to negative iimpact on brain function.Reference:Martinez-Lomeli, J., Deol, P., Deans, J.

A recent study conducted at the University of Texas MD Anderson Cancer Center showed that patients with a history of colorectal cancer who added a cup of navy beans daily to their regular meals saw positive changes in their gut microbiome after just 4 weeks. Listen in this week as Dee discusses the details of this study and how the changes in microbiome aid in colorectal cancer prevention and treatment.Reference:Zhang, X., Irajizad, E., Hoffman, K.

Autophagy is a natural biochemical self-preservation process whereby the body cleans out damaged cells in order to regenerate newer, healthier cells. There are certain diet and lifestyle factors that aid or inhibit autophagy, leading either to improved health or accelerated degeneration.  Listen in this week as Dee discusses the mechanisms of autophagy and the best ways to ensure its optimal benefits.Reference:Aman, Y., Schmauck-Medina, T., Hansen, M., Morimoto, R.
