Which fats in food are bad for the heart?

Saturated fat: Most saturated fat is animal fat found in meat and dairy products. Sources of saturated fat include: beef fat, lard, chicken skin; dairy products such as butter, cheese, cream; coconut oil, palm oil...

Some studies have shown that consuming a lot of saturated fat can increase bad cholesterol (LDL). High LDL levels can increase the risk of heart disease. Eating more saturated fat seems to increase the amount of LDL in the body. However, studies have shown that not all LDL is bad.

Animal fats (such as lard) should be used intermittently but should not account for more than 10% of daily fat intake.

Eating a lot of processed meat in your diet increases your risk of heart disease.

Trans fat: Trans fat is a harmful fatty acid found in many processed foods. Regularly eating this type of fat will increase the risk of cardiovascular disease because the chemical structure of trans fat has the ability to increase bad cholesterol and decrease good cholesterol.

Most trans fats are artificial and are found in processed foods, fried foods, fast foods, baked goods, pastries...
Trans fats are also found in small amounts in dairy foods, animal meats...

However, natural trans fats are not as worrisome as artificial trans fats. They are made from refined fats and oils, and appear in processed foods through the use of hydrogenated or partially hydrogenated vegetable oils (deep-frying, baking, etc.).

To avoid trans fats and limit saturated fats, the best way is to follow a healthy diet, prioritizing healthy fats, increasing green vegetables, fruits, whole grains... instead of processed foods and fast foods.
