All about Cholesterol: The Good, The Bad, The Ugly

Cholesterol is a waxy substance found in the bloodstream and in all your body's cells. It is an essential component for the proper functioning of the body as it helps in the production of hormones, vitamin D, and bile acids that aid in the digestion of fats. However, high levels of cholesterol in the blood can lead to a buildup of plaque in the arteries, increasing the risk of heart disease and stroke.

On one hand, it is an important component of cell membranes and is used to produce hormones and bile acids, which help with digestion.

On the other hand, high levels of low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, can build up in the walls of the arteries, leading to a condition called atherosclerosis. Over time, this can cause the arteries to narrow, reducing blood flow to the heart and brain and increasing the risk of heart attack, stroke, and other cardiovascular diseases.

Causes of High Cholesterol

1. Diet affecting Cholesterol levels:

   A diet high in saturated and trans fats can increase cholesterol levels. Foods high in saturated fat include meat, dairy products, and baked goods, while foods high in trans fat include deep-fried foods and baked goods made with partially hydrogenated oils.
   

2. Lack of physical activity:

   Physical inactivity can increase cholesterol levels and reduce the amount of HDL cholesterol, which is considered "good" cholesterol.
   

3. Obesity:

   Being overweight or obese can increase cholesterol levels and increase the risk of heart disease.
   

4. Smoking:

   Smoking can reduce the amount of HDL cholesterol and increase the risk of heart disease.
   

5. Genetics:

   High cholesterol can run in families and be due to inherited genetic factors.
   

6. Age and gender:

   Cholesterol levels generally increase as people age and are typically higher in men than in women before menopause.
   

7. Medical conditions:

   Certain medical conditions, such as hypothyroidism, liver disease, and kidney disease, can contribute to high cholesterol levels.
   

Range of Total Cholesterol in Adults

The normal levels of cholesterol in the blood vary depending on a person's age, gender, and overall health. However, the following are general guidelines for total cholesterol levels:

• Desirable: Less than 200 mg/dL
• Borderline high: 200-239 mg/dL
• High: 240 mg/dL or higher

It's also important to note that individual LDL and HDL levels are also important indicators of heart disease risk. The following are general guidelines for LDL and HDL levels:

• LDL (bad) cholesterol:
  • Optimal: Less than 100 mg/dL
  • Near or above optimal: 100-129 mg/dL
  • Borderline high: 130-159 mg/dL
  • High: 160-189 mg/dL
  • Very high: 190 mg/dL or higher
• HDL (good) cholesterol:
  • Low: Less than 40 mg/dL (men) or less than 50 mg/dL (women)
  • Optimal: 60 mg/dL or higher

It's important to note that these are general guidelines and that the ideal cholesterol levels may vary based on individual circumstances. It's always best to discuss your specific cholesterol levels and heart disease risk with a healthcare professional.

When should you see a Doctor against your Cholesterol Levels

It's important to have regular cholesterol screenings to monitor your cholesterol levels and overall heart health, but if any of the below applies to you, then you should consider visiting your Doctor:

1. High cholesterol levels:

   If your total cholesterol level is higher than 200 mg/dL or your LDL (bad) cholesterol level is higher than 100 mg/dL, it may be time to see a doctor.

2. Family history of heart disease or high cholesterol:

   If you have a family history of heart disease or high cholesterol, you may be at higher risk and should see a doctor to discuss your cholesterol levels and heart disease risk.

3. Other risk factors for heart disease:

   Other risk factors for heart disease, such as smoking, high blood pressure, diabetes, and being overweight or obese, can also increase your risk for high cholesterol levels. If you have any of these risk factors, it's important to see a doctor to discuss your cholesterol levels and heart disease risk.

4. Symptoms of heart disease:

   If you experience symptoms of heart disease, such as chest pain, shortness of breath, or irregular heartbeats, it's important to see a doctor as soon as possible.

How Can You LOWER Your Cholesterol Levels Naturally

There are several natural ways to help lower cholesterol levels:

1. Exercise regularly:

   Regular physical activity, such as brisk walking or cycling, can help lower cholesterol levels and improve heart health. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.

2. Maintain a healthy weight:

   Being overweight or obese can increase cholesterol levels and increase your risk of heart disease. Losing even a small amount of weight can help lower cholesterol levels.

3. Follow a healthy diet:

   A diet low in saturated and trans fats and high in fiber, fruits, and vegetables can help lower cholesterol levels. See the specific dietary recommendations in the following section.

4. Limit alcohol consumption:

   Drinking alcohol in moderation may have some benefits for heart health, but excessive alcohol consumption can raise cholesterol levels and increase heart disease risk.

5. Add soluble fiber to your diet:

   Foods high in soluble fiber, such as oats, barley, legumes, and some fruits and vegetables, can help lower cholesterol levels by binding with cholesterol in the gut and preventing its absorption.

6. Increase plant sterols and stanols:

   Plant sterols and stanols, which are naturally occurring compounds found in plants, can help lower cholesterol levels by blocking the absorption of cholesterol in the gut. Foods enriched with plant sterols and stanols, such as spreads, juices, and dairy products, are available in stores.

7. Take natural supplements:

   Some natural supplements, such as psyllium, soy protein, and plant sterols and stanols, have been shown to help lower cholesterol levels. However, it's important to speak with your doctor before taking any supplements, as they can interact with other medications and may have side effects.

It's important to keep in mind that while these natural methods can help lower cholesterol levels, they are not a substitute for medical treatment and should be used in conjunction with a healthy lifestyle and, if necessary, cholesterol-lowering medication prescribed by a doctor.

Dietary Recommendations For People With High Cholesterol Levels

A healthy diet is important in maintaining healthy cholesterol levels. Here are some dietary recommendations to help keep your cholesterol levels in check:

1. Limit saturated and trans fats:

   These types of fats can raise cholesterol levels and increase your risk of heart disease. Avoid or limit foods high in saturated fats such as fatty meats, full-fat dairy products, and baked goods. Also, try to avoid foods containing partially hydrogenated oils, a source of trans fats.

2. Increase fiber intake:

   Foods high in fiber, such as fruits, vegetables, whole grains, and legumes, can help lower cholesterol levels by binding with cholesterol in the gut and preventing its absorption. Aim for at least 25-30 grams of fiber per day. You may want to read our post on The Importance of dietary fibre and 30 sources of it

3. Include healthy fats:

   Good sources of unsaturated fats, such as olive oil, avocados, nuts, and fatty fish, can help lower cholesterol levels. Try to replace saturated and trans fats with these healthier fats.

4. Limit dietary cholesterol:

   While dietary cholesterol can affect blood cholesterol levels, it is not as significant as saturated and trans fats. However, limiting dietary cholesterol from animal products such as eggs, dairy, and meat can help maintain healthy cholesterol levels.

5. Eat plenty of fruits and vegetables:

   Fruits and vegetables are low in saturated fat and high in fiber, making them a great option for maintaining healthy cholesterol levels. Aim for at least five servings of fruits and vegetables per day.

6. Limit alcohol consumption:

   Drinking alcohol in moderation may have some benefits for heart health, but excessive alcohol consumption can raise cholesterol levels and increase heart disease risk.

A healthy diet is just one aspect of maintaining healthy cholesterol levels. Regular physical activity, maintaining a healthy weight, and not smoking are also important factors in reducing heart disease risk. It's always best to discuss your specific dietary needs and heart disease risk with a healthcare professional. So Cholesterol is an essential component of the body, but high levels can lead to serious health problems.

Regular cholesterol tests can also help monitor your levels and assess your risk, allowing for prompt and appropriate treatment if necessary.
