#011 CHORIBar: Micronutrients, Fiber & Polyphenols in a Bar
Dr. Bruce Ames, Dr. Joyce McCann, and Dr. Mark Shigenaga discuss the CHORI bar, a low-calorie, micronutrient- and fiber-dense nutrition bar. They explain how its components improve HDL, lower triglycerides and small LDL particles, and enhance insulin sensitivity in adults, even without diet changes, by filling nutrient gaps and optimizing metabolism.

6 Key Concepts
Essential Vitamins and Minerals
These are about 30 substances (15 minerals, 15 vitamins) that must be obtained from the diet. They act as cofactors for enzymes, which are proteins that perform metabolic work in the body, and their deficiency can inactivate a significant portion of metabolism.
Gut Barrier Function
The gut wall acts as a crucial barrier preventing bacteria and food antigens from entering the body. Soluble fiber, a component of the CHORI Bar, is metabolized by gut bacteria to produce nutrients that strengthen this barrier and support the immune system, thereby preventing 'leaky gut' and chronic inflammation.
Reverse Cholesterol Transport
This is a vital function of HDL particles, especially the larger HDL2b type. It involves HDL taking cholesterol from peripheral tissues, including atherosclerotic plaques in arteries, and transporting it back to the liver for removal, which helps prevent cardiovascular disease.
LDL Particle Sizes
LDL cholesterol exists in various particle sizes. Large, buoyant LDL particles are generally considered neutral or even beneficial, while small, dense LDL particles are strongly associated with increased cardiovascular risk and are often a biomarker of inflammation.
Triage Theory of Micronutrients
This theory posits that when the body experiences a micronutrient deficiency, it prioritizes the allocation of the limited nutrient to functions essential for immediate survival and reproduction. This rationing often comes at the expense of long-term health maintenance, such as DNA repair or protection against chronic diseases.
Nutrient Synergy
This concept highlights that multiple nutrients and dietary components, such as vitamins, minerals, fiber, polyphenols, and omega-3s, work together in a complementary fashion to optimize metabolism. Unlike 'magic bullet' supplements, the CHORI Bar's effectiveness stems from the combined action of its diverse ingredients.
10 Questions Answered
Essential vitamins and minerals primarily act as cofactors for enzymes, which are proteins that carry out metabolic processes. Without adequate amounts, a significant portion of the body's metabolism can be inactivated.
The CHORI Bar contains vitamins and minerals at levels generally lower than those in a vitamin pill, aiming to fill dietary gaps rather than provide megadoses. It also uniquely combines multiple types of fiber, omega-3 fatty acids, and polyphenols, making it far more complex than most market bars which often resemble candy bars.
Insoluble fiber promotes gut movement and laxation, while soluble fiber creates a viscous barrier during food absorption and is metabolized by gut bacteria. These bacteria produce metabolites that feed the gut wall, strengthening it and powering the immune system, which prevents 'leaky gut' and associated inflammation.
The CHORI Bar is designed to fill nutrient gaps in typical Western diets, benefiting people who eat poorly or even those who think they eat well but still have deficiencies. It is particularly effective for middle-aged adults and overweight/obese individuals, especially those with lower levels of chronic inflammation.
In lean, middle-aged adults, the CHORI Bar robustly increases HDL, specifically the larger, healthier HDL2b particles, which are crucial for reverse cholesterol transport and removing cholesterol from arteries.
In overweight or obese individuals with lower inflammation, the CHORI Bar improves the LDL lipid profile by reducing small, dense LDL particles (associated with cardiovascular risk) and slightly increasing large, buoyant LDL particles. It also improves insulin sensitivity, waist circumference, blood pressure, and can lead to weight loss.
Younger individuals are generally more resilient and may not yet have accumulated the metabolic damage or need for reverse cholesterol transport that older adults do. Growth hormone in youth may also offer protection, allowing them to tolerate dietary stressors better.
The triage theory suggests that when the body is deficient in certain micronutrients, it prioritizes their allocation to functions essential for immediate survival and reproduction, often at the expense of long-term health maintenance, such as DNA repair or chronic disease prevention.
The CHORI Bar's effects are not due to a single 'magic bullet' ingredient but rather a synergistic action of multiple components (vitamins, minerals, fibers, polyphenols, omega-3s) working together to optimize metabolism. Deconstruction trials show that at least three to four ingredients must be present to achieve effects like raising HDL.
High levels of chronic internal inflammation can blunt almost all the beneficial effects of the CHORI Bar in obese individuals, including improvements in HDL, LDL, and insulin sensitivity. The body's inflammatory response diverts resources, making it less responsive to metabolic tuning.
17 Actionable Insights
1. Consume Essential Micronutrients
Ensure your diet provides the right amounts of about 30 essential vitamins and minerals, as these are crucial cofactors for enzymes that drive your metabolism.
2. Prevent Micronutrient Triage
Avoid even slight deficiencies in vitamins and minerals, as your body will ’triage’ by prioritizing short-term survival functions over long-term health protections like DNA repair.
3. Prioritize Whole Foods
Understand that whole foods contain multiple ingredients working in concert, with components facilitating absorption or slowing it down, making them more effective for nutrition than single-ingredient supplements.
4. Consume Diverse Dietary Fiber
Include both soluble and insoluble fibers in your diet; insoluble fiber promotes gut movement, while soluble fiber feeds gut bacteria, strengthens the gut wall, and powers the immune system.
5. Strengthen Your Gut Barrier
Aim to keep your gut barrier as strong as possible to prevent ’leaky gut,’ which can lead to inflammation and metabolic problems like weight gain, insulin resistance, and diabetes.
6. Empower Cellular Mitochondria
Consume nutrients that power your mitochondria to ensure sufficient ATP production, which is essential for maintaining the integrity of your GI tract and overall cellular energy.
7. Embrace Preventive Nutrition
Recognize the immense power of nutrition as the ’low-hanging fruit’ for preventive medicine and living a long life, often being more effective than drugs for overall health.
8. Choose Diet Over Drugs
Opt for a balanced diet to improve overall health, as it works by making metabolism function better without the side effects often associated with drugs that perturb metabolic processes.
9. Avoid Empty Calorie Foods
Minimize consumption of ’empty calories’ which are low in essential vitamins and minerals, as these can negatively impact metabolism and overall health.
10. Fill Nutritional Gaps
Focus on filling nutritional gaps in your diet to improve metabolism, even if your overall diet isn’t perfectly balanced.
11. Ensure Sufficient Vitamin D
Make sure you get enough vitamin D, as deficiency (common in 70% of the population) can negatively impact the regulation of thousands of genes.
12. Eat Magnesium-Rich Foods
Consume green vegetables like kale or spinach, and nuts, to obtain sufficient magnesium, which is a crucial mineral for a balanced diet.
13. Balance Nutrient Intake
Aim to achieve a balanced intake of nutrients, as consuming excessive amounts of certain nutrients can actually lead to adverse health outcomes.
14. Acknowledge Diet Imperfections
Understand that even seemingly healthy diets can have vitamin and mineral deficiencies, making it challenging to achieve a ‘perfect diet’ without conscious effort.
15. Critically Evaluate Nutrition Claims
Approach nutrition claims with skepticism, especially those based solely on epidemiological associations, as understanding underlying metabolic mechanisms is crucial to avoid drawing wrong conclusions.
16. Beware of “Health Bars”
Be cautious of many ‘health bars’ on the market, as they are often high in calories and sugar, resembling candy bars rather than providing comprehensive nutritional benefits.
17. Stay Informed on Cory Bar
Visit bruceames.org/CoryBar for updates on the Cory Bar’s availability and research, as it aims to provide comprehensive nutritional benefits.
