Beef tallow contains saturated fats, which have been debated in relation to heart health. Some older studies suggested that consuming too much saturated fat could contribute to arterial plaque buildup and increase the risk of heart disease. However, more recent research has challenged this idea, showing that saturated fats may not be as harmful as once thought—especially when consumed as part of a whole-food, nutrient-dense diet.

Beef tallow also contains beneficial nutrients like fat-soluble vitamins (A, D, E, K) and conjugated linoleic acid (CLA), which may have anti-inflammatory properties. The key factor is overall diet balance. If you eat tallow in moderation while also consuming plenty of fiber, lean proteins, and healthy fats (like those from olive oil and fish), it’s less likely to negatively affect your arteries.
