Saturated fats: Excessive saturated fat found in red meat (beef, mutton), butter, ghee, and cheese increases cholesterol.
Trans fats: Trans fats found in bakery products, fried foods, and packaged foods increase bad cholesterol (LDL) in the blood and reduce good cholesterol (HDL).
Lack of exercise: In people with a sedentary lifestyle, the body is unable to digest fat effectively, and it accumulates in the blood.
Obesity: Obesity causes high triglyceride levels in the blood and low good cholesterol.
Genetics: If your parents or siblings have high cholesterol in your family, you are more likely to have it.
Smoking and alcohol: Smoking damages blood vessels and lowers good cholesterol (HDL). Alcohol increases triglyceride levels.
