Nutrition Made Simple! - The TRUTH on Tallow | Fad or Fact?
The speaker addresses the recent interest in beef tallow, particularly due to its promotion by public figures like RFK Jr. Tallow, a form of beef fat, is often used for cooking due to its high smoke point. However, its health effects are debated. Tallow is high in saturated and monounsaturated fats, with some micronutrients like vitamins A, D, and B12. It raises LDL cholesterol and triglycerides more than liquid oils like olive oil but less than butter. The speaker warns against the appeal to nature fallacy, noting that natural doesn't always mean healthy. While tallow is more stable under heat, its long-term health effects are not well-documented. The speaker suggests favoring liquid oils like olive and canola oil, which have been shown to lower disease risk compared to solid fats like butter and tallow. They recommend cooking methods that don't involve high temperatures and avoiding the reuse of fats. Personalizing diet based on individual blood work is also advised.
Key Points:
- Beef tallow is high in saturated and monounsaturated fats, raising LDL cholesterol and triglycerides more than liquid oils but less than butter.
- Tallow is more stable under heat, making it suitable for high-temperature cooking, but its long-term health effects are unclear.
- Natural doesn't always mean healthy; tallow's industrial uses don't determine its health impact.
- Favor liquid oils like olive and canola oil for lower disease risk compared to solid fats like butter and tallow.
- Personalize dietary choices based on individual blood work to manage lipid levels effectively.

1. 📣 Introduction to Tallow and RFK Jr's Advocacy
- RFK Jr advocates for using beef tallow in cooking and frying, promoting the slogan 'make frying oil tallow again'.
- He actively promotes merchandise supporting beef tallow and is seen endorsing tallow fries in a fast food setting.
- His campaign highlights a preference for tallow over seed oils, particularly in fast food, emphasizing the potential health and taste benefits.
- RFK Jr's advocacy is part of a broader movement to replace seed oils with animal fats, citing potential health advantages like improved cholesterol levels and a reduction in processed oil consumption.
- Events and promotional campaigns are part of his strategy to raise awareness about the benefits of tallow, aiming to shift public perception and industry practices.
2. 🥩 What is Beef Tallow?
- Beef tallow is created by melting and purifying beef fat, which is then cooled to solidify.
- It is primarily used for cooking, including frying and baking, due to its high smoke point.
- The smoke point of beef tallow ranges from 200-204 Celsius, but can vary depending on purity and source location within the animal, ranging from mid 100s to mid 200s Celsius.
- Beef tallow is a traditional cooking fat, historically valued for its flavor and high-temperature stability.
- Nutritionally, beef tallow is rich in saturated fats and provides a natural source of energy.
- Compared to other cooking oils, beef tallow offers a distinct flavor profile and is often preferred in traditional recipes.

5. 📊 Tallow's Impact on Blood Lipids
- Tallow raises LDL cholesterol more than liquid oils like olive oil but less than butter, suggesting a moderate impact among saturated fats.
- The study adjusted for dietary cholesterol by adding egg yolk to isolate the saturated fat content, highlighting the specific effect of tallow.
- Compared to olive oil, tallow also increased triglyceride levels, indicating a broader impact on lipid profiles.
- While blood lipid markers such as LDL cholesterol and triglycerides are informative, the study emphasizes the importance of evaluating long-term outcomes like heart disease and mortality risk.
- Existing data on common fats such as butter, olive oil, and seed oils is extensive, yet research on tallow remains limited, suggesting a need for further studies to understand its health implications fully.
6. 🧈 Comparing Solid and Liquid Fats
- Solid fats like butter and ghee are linked to higher risks of disease and death compared to liquid oils, with olive oil being a healthier alternative.
- Tallow may have an intermediate health impact between butter and liquid oils due to its nutrient composition and effect on blood lipids.
- Long-term human data on tallow is needed for a definitive understanding of its health impacts.
- Studies suggest avoiding all oils, including olive oil, tallow, and butter, in favor of whole food sources like nuts and seeds for better health outcomes.
7. 🔍 Trans Fats in Tallow
- Tallow contains more trans fats than liquid oils like olive oil and seed oils, but less than industrial products before bans.
- Naturally occurring trans fats in tallow are perceived to be less harmful than industrial trans fats due to their lower quantity and natural origin.
- The debate continues on the health impact of these trans fats, though current levels in tallow are generally considered insufficient to pose significant health risks.
- For comprehensive health assessments, comparisons with other fats like butter or margarine should be included, highlighting their trans fat content and health implications.
8. 🔥 Heat Stability of Tallow
- Tallow, rich in saturated fat, degrades slower under prolonged high heat treatments such as deep frying, compared to liquid oils like olive or canola.
- The slower degradation rate of saturated fats suggests they are more stable for cooking involving repeated heating, potentially reducing the need for frequent oil replacement.
- The health effects of consuming fats prepared at high temperatures are still uncertain, indicating a need for more human studies to understand potential impacts.
- Cooking with liquid oils, including olive and canola, is associated with lower disease and mortality risks compared to butter, highlighting their health benefits.
- There may be a critical heat exposure threshold after which even stable oils degrade significantly, possibly negating their health advantages.
9. 🔬 Oxidation and Health Risks
- A study was conducted to compare the effects of tallow and seed oil (corn oil) on oxidation levels in humans, with participants consuming a diet where 20% of their calories came from each fat source over a period of one month.
- No significant difference in oxidized LDL levels was found between the two groups, suggesting that over the short term, these fats do not differ in their impact on oxidation.
- Key limitations of the study included its small sample size, short duration, and the absence of specific cooking details, such as temperature and techniques, which could influence results.
- The study implies that while no short-term differences in oxidation were observed, longer exposure or different cooking methods, particularly high-temperature techniques like deep frying, might yield different outcomes.
- It suggests that focusing on the type of fat used in fast food frying might be less critical than broader dietary improvements for significant health impacts.
10. 🥗 Dietary Strategy and Recommendations
- Favor liquid oils like olive oil and canola oil, and include nuts, seeds, and seafood in the diet, while avoiding solid fats such as butter, tallow, lard, and cream, to promote heart health and reduce cholesterol levels.
- Utilize lower-temperature cooking methods like sautéing, steaming, and boiling to preserve nutrients and avoid the health risks associated with high-temperature cooking and deep frying.
- To maintain the integrity of fats and avoid potential health hazards, do not reheat or reuse fats; discard any leftover fats after cooking.
- Personalize dietary fat intake based on individual blood work results, specifically lipid panels, to tailor the balance of unsaturated and saturated fats to one's health needs.
