how does animal fat affect my health?

The impact of animal fat on health is nuanced and involves considering the types of fats you consume. Here's a summary based on insights from Huberman Lab, featuring experts like Andrew Huberman and Layne Norton:

1. Saturated Fats and Heart Disease: Consuming saturated fats, which are abundant in animal products, is generally linked to raising LDL cholesterol levels, an independent risk factor for heart disease. However, not all saturated fats have the same effect. For example, stearic acid may not raise LDL cholesterol as much as other saturated fats 1.

2. Substituting with Unsaturated Fats: Replacing saturated fats with unsaturated fats, like those found in olive oil, tends to reduce the risk of heart disease more effectively. Polyunsaturated fats are particularly noted for having a strong effect on reducing heart disease risk 1.

3. Inflammation and Liver Health: Saturated fats may also be more detrimental than fructose in terms of liver health, potentially increasing liver fat significantly. Some studies suggest a stronger adverse effect of saturated fat on liver fat compared to other types of fats 2.

4. Cholesterol Complexity: The relationship between dietary cholesterol (found in animal fats) and blood cholesterol levels (LDL and HDL) is complex and debated. Cholesterol is crucial for cellular functions; however, excessive saturated fat intake can influence LDL cholesterol levels, potentially impacting health. The consensus suggests moderation and a balanced diet 3.

These insights suggest that while saturated fats are not inherently toxic, consuming them in moderation and considering healthier alternatives, like unsaturated fats, can be beneficial for heart and liver health.
