What Beef Tallow Does to Your Heart Health

Beef tallow the rendered fat from cows was once a staple in home kitchens and commercial fryers alike. Today, it’s making a comeback among fans of traditional diets, keto cooking, and ancestral eating trends. But before you start swapping out your olive oil for beef tallow, it’s worth looking at what this animal fat does to your heart health over time.

1. It May Raise Cholesterol and Triglycerides

Beef tallow is high in saturated fat, and decades of research link diets rich in saturated fats to higher levels of:

• Total cholesterol

• LDL (“bad”) cholesterol

• Triglycerides

These blood fats can build up in the arteries, increasing the risk of cardiovascular disease. According to the American Heart Association, keeping saturated fat intake low is one of the most important steps in supporting heart health especially for individuals who already have risk factors like high blood pressure, diabetes, or a family history of heart disease.

2. It Could Increase Your Risk of Heart Attack or Stroke

When saturated fats raise cholesterol levels, they contribute to atherosclerosis the gradual buildup of plaque inside the arteries. This leads to:

• Narrowed arteries

• Reduced blood flow

• Increased strain on the heart

Over time, this damage raises the likelihood of life-threatening events, such as heart attacks and strokes. A diet high in saturated fats, like those found in beef tallow, is a known contributor to this process.

3. It May Impair Blood Sugar Control

Regularly cooking with high-saturated-fat ingredients like beef tallow may also affect insulin sensitivity. Research shows that excess saturated fat can:

• Reduce the effectiveness of insulin receptors

• Suppress the body’s natural insulin production

• Lead to higher blood sugar levels over time

This can increase the risk of type 2 diabetes, which often goes hand-in-hand with cardiovascular disease. Insulin resistance is considered a major risk factor for heart complications.

How Much Saturated Fat Is Too Much?

The Dietary Guidelines for Americans recommend limiting saturated fat to less than 10% of total daily calories. Some experts, including the American Heart Association, go further suggesting a limit of 6% or less, especially for people with elevated cardiovascular risk.

To put that into perspective:

• On a 2,000-calorie diet, 10% equals 22 grams of saturated fat per day

• One tablespoon of beef tallow contains 6.5 grams about 30% of that daily maximum

If you're also eating red meat, full-fat dairy, or processed snacks, you can easily exceed your daily saturated fat limit without realizing it.

Can You Still Cook With Beef Tallow?

No single food is entirely harmful in isolation. If you enjoy cooking with beef tallow occasionally, it can be part of a balanced diet as long as your overall saturated fat intake remains low and your meals include heart-healthy foods like fruits, vegetables, whole grains, and unsaturated fats.

The bigger concern is how beef tallow fits into your total dietary pattern. If you’re also eating other sources of saturated fats and limiting fiber-rich, plant-based foods, the risks begin to add up.

Heart-Healthier Cooking Fat Alternatives

If heart health is a top priority, consider swapping beef tallow for fats that are rich in unsaturated fatty acids. These fats have been shown to improve cholesterol profiles and reduce inflammation.

Try these alternatives:

• Extra Virgin Olive Oil (EVOO): Rich in monounsaturated fats and polyphenols that support cardiovascular function

• Avocado Oil: Helps reduce inflammatory markers and supports healthy cholesterol levels

• Canola Oil: Low in saturated fat and contains omega-3 fatty acids; has been shown to reduce LDL cholesterol

Studies consistently show that replacing saturated fats with unsaturated fats not just cutting out fat altogether has the most beneficial effect on heart health.

Beef tallow may add flavor and crispness to your cooking, but using it regularly could come at a cost to your heart especially when it crowds out healthier fats. Being mindful of your overall saturated fat intake and balancing your meals with nutrient-dense, heart-friendly ingredients is the key.
