– your total cholesterol level should be below 4 mmol/l – your bad LDL cholesterol level should be below 2 mmol/l – your good HDL cholesterol level should be above 1 mmol/l. If your total cholesterol level is over 4 and your LDL is over 2, this shows that you might be at higher risk of a heart attack or stroke.
The optimal cholesterol ratio is between 3.5 and 1, while a ratio of 5 or below is considered normal. 4 A cholesterol ratio within the normal range means that your cholesterol levels are likely not contributing to cardiac risk.
LDL -cholesterol levels greater than 3.5 mmol/L are considered elevated for some people at low cardiovascular risk and most individuals at intermediate risk and may need behavior modifications and/or pharmacological treatment Note 5 (see About cholesterol).
A person is considered at high risk for developing heart disease if their total cholesterol level is higher than 240 mg/dL, LDL levels are higher than 160 mg/dL (190 mg/dL is even higher risk), and if the HDL level is below 40 mg/dL.
According to StatPearls, you should try to keep your cholesterol ratio below 5, with the ideal cholesterol ratio being 3.5. That said, the ideal cholesterol ratios for men and women may differ. The ideal total cholesterol level for an adult is 200 mg/dL or less .
For most healthy adults (19 and older), your total cholesterol should be less than 200 mg/dL, your LDL less than 100 mg/dL, and your HDL greater than 40 mg/dL. For children (19 and younger), total cholesterol should be less than 170 mg/dL, LDL less than 110 mg/dL, and HDL greater than 45 mg/dL.
Most adults should keep their LDL below 100 milligrams per deciliter (mg/dL). If you have a history of atherosclerosis, your LDL should be below 70 mg/dL. What is a bad level for LDL? An LDL level above 100 mg/dL raises your risk of cardiovascular disease.
Eating too much saturated fat or trans fats can result in unhealthy cholesterol levels. Saturated fats are found in fatty cuts of meat and full-fat dairy products. Trans fats are often found in packaged snacks or desserts.
If high levels of stress are part of your daily life, you are at risk for high cholesterol, according to research. In a large study of more than 91,500 adults in different professions, job-related stress was linked to high cholesterol, including high LDL and low HDL cholesterol.
LDL (low-density lipoprotein) cholesterol, sometimes called “bad” cholesterol, makes up most of your body's cholesterol. High levels of LDL cholesterol raise your risk for heart disease and stroke.
Total Cholesterol: <4.0 mmol/L (Individuals at high risk) <5.5 mmol/L (General population) Low Density Lipoprotein Cholesterol (LDL): < 1.8mmol/L (Individuals at high risk) < 2.0 mmol/L (General population)
Types of Cholesterol
Levels of LDL cholesterol higher than 130 milligrams per deciliter (mg/dL) are linked to an increased risk for ischemic stroke.
In general: The higher the ratio, the higher the risk. Most healthcare providers want the ratio to be below 5:1. A ratio below 3.5:1 is considered very good.
The following levels are considered to be "good" in healthy people: Total cholesterol: Levels below 200 mg/dL (5.2 mmol/L) LDL cholesterol: Levels below 130 mg/dL (3.4 mmol/L) HDL cholesterol: Levels above 40 mg/dL (1 mmol/L) in men and above 50 mg/dL (1.3 mmol/L) in women.
Your HDL (“good” cholesterol) is the one number you want to be high (ideally above 60). Your LDL (“bad” cholesterol) should be below 100. Your total should be below 200. Talk with your provider about what your results mean for you and how to manage your cholesterol.
Saturated fats — such as those in meat, butter, cheese and other full-fat dairy products — raise your total cholesterol. Decreasing your consumption of saturated fats to less than 7 percent of your total daily calorie intake can reduce your LDL cholesterol by 8 to 10 percent.
Tisch Center for Women's Health at the NYU Langone Medical Center, says it can take between three to six months to see lower LDL numbers through just diet and exercise, noting that it takes longer to see changes in women than men.
Answer From Francisco Lopez-Jimenez, M.D. Chicken eggs are an affordable source of protein and other nutrients. They're also naturally high in cholesterol. But the cholesterol in eggs doesn't seem to raise cholesterol levels the way some other foods, such as those high in trans fats and saturated fats, do.
When people have high cholesterol their LDL (bad) is high and their HDL (good) is low. Eating healthy, regular exercise and drinking plenty of water will help to bring down cholesterol levels within 2-3 weeks.
100 – 129 mg/dL is near ideal. 130 – 159 mg/dL is borderline high. 160 – 189 mg/dL is considered high. 190 mg/dL and higher is considered to be very high.
Goals for Your Cholesterol Levels
Women of any age should have an HDL level of 40 or higher. If you already have heart disease or diabetes, or your doctor estimates that your 10-year risk of heart disease is 20 percent or higher, try to keep your LDL level below 100.
A normal total cholesterol level for adults without heart disease is less than 200 mg/dL.
