During Dr. Ben Bikman’s latest episode of The Metabolic Classroom lectures, Ben explores the metabolic effects of nicotine, emphasizing its influence beyond its addictive properties and its association with lung health and its connection to insulin resistance.

Nicotine, a naturally occurring alkaloid found primarily in tobacco plants, is widely consumed through various products such as cigarettes, cigars, chewing tobacco, e-cigarettes, and nicotine replacement therapies like gums and patches. While most discussions on nicotine focus on its addictive qualities and respiratory impact, Ben highlights its significant effects on metabolism, including interactions with fat cells, insulin, and the nervous system.

Nicotine primarily stimulates the sympathetic nervous system by increasing the release of catecholamines like epinephrine and norepinephrine. These stress hormones activate the “fight or flight” response, resulting in elevated heart rate, blood pressure, and metabolic rate.

Nicotine’s ability to increase lipolysis, the breakdown of stored fat into free fatty acids, often leads to temporary weight loss. However, its chronic use disrupts fat metabolism by impairing mitochondrial fat oxidation, leading to fat cell hypertrophy (enlargement). This enlargement, particularly in visceral fat, contributes to insulin resistance, fatty liver disease, and systemic inflammation.

Ben also examines nicotine’s role in insulin resistance through its activation of specific cellular pathways. Nicotine increases ceramide production, which disrupts insulin signaling by deactivating key proteins essential for glucose uptake. Additionally, nicotine activates receptors like RAGE (Receptor for Advanced Glycation End Products) and TLR4 (Toll-like Receptor 4), which further drive ceramide production and inflammation. This creates a self-perpetuating cycle that exacerbates metabolic dysfunction and promotes chronic insulin resistance.

The classroom lecture highlights the paradoxical nature of nicotine’s metabolic effects. While it temporarily enhances fat metabolism and weight loss, chronic exposure reverses these effects, promoting fat storage, inflammation, and severe insulin resistance. Ben emphasizes the metabolic risks associated with nicotine, especially in the context of rising vaping trends among younger populations. He concludes by urging greater awareness of nicotine’s systemic effects, particularly its hidden role in metabolic health.

For The Metabolic Classroom lecture this week, Dr. Bikman explores the often-overlooked effects of oxalates on human health, with a focus on their impact on metabolic, kidney, cardiovascular, gut, and joint health.

Oxalates are natural compounds found in various plants, including leafy greens like spinach and kale, as well as certain nuts, seeds, grains, and legumes. They serve as a defense mechanism for plants against herbivores, as their high concentrations can cause irritation and reduce nutrient absorption. While often thought of as harmless, oxalates can act as “antinutrients” by binding to essential minerals such as calcium, magnesium, and iron, limiting their bioavailability and potentially leading to deficiencies.

Oxalates form crystals with calcium, creating a compound known as calcium oxalate. When these crystals accumulate in the body, they can contribute to kidney stones—a problem that affects many people. Ben explains that calcium oxalate crystals make up about 80% of all kidney stones, underscoring the connection between oxalate consumption and kidney health. Individuals prone to kidney stones, particularly those consuming high-oxalate diets or taking high doses of vitamin C (which the body can convert to oxalates), may face a heightened risk.

To mitigate oxalate-related health risks, Dr. Bikman suggests practical strategies, including reducing high-oxalate foods, ensuring adequate calcium intake to bind oxalates in the gut, staying hydrated to aid in oxalate excretion, and consuming fermented foods or probiotic supplements to support a healthy gut microbiome. He also highlights the importance of a balanced approach to vitamin C supplementation, as excessive intake may increase oxalate production in the body.

During this week’s episode of The Metabolic Classroom, Dr. Bikman discusses the impact of microplastics on metabolic health, focusing on their effects on fat cells, insulin resistance, and blood vessel health.

Microplastics—tiny plastic particles under five millimeters—are now ubiquitous in our environment, entering the body through food, water, air, and skin products. Their pervasiveness poses serious concerns due to their accumulation in human tissues and the release of harmful chemicals like BPA (bisphenol A) and phthalates, which disrupt normal hormone functions and lead to various health issues.

Ben details how microplastics affect fat cell biology, particularly through BPA and phthalates, which mimic hormones like estrogen and testosterone, causing increased fat storage and even promoting fat cell growth and multiplication (hyperplasia and hypertrophy). This hormone disruption and fat cell expansion result in greater fat storage and elevated inflammation, contributing to insulin resistance, obesity, and chronic diseases like type 2 diabetes.

Professor Bikman also explores how microplastics affect vascular health, citing studies that show microplastic particles in atherosclerotic plaques. These particles attract macrophages that attempt to remove the microplastics but instead form “foam cells,” which contribute to plaque formation and heighten the risk of cardiovascular disease.

Ben concludes with recommendations to limit microplastic exposure, such as avoiding plastic containers for long-term water storage and choosing BPA-free, phthalate-free products, especially for food and beverages.
