What is cholesterol and how to manage it

 

Cholesterol is a fat-like, waxy substance found in your blood and in every cell of your body. It’s essential for many vital functions, such as:

• Building cell membranes
• Producing hormones like estrogen, testosterone, and cortisol
• Making vitamin D
• Creating bile acids that help digest fats

Your liver makes most of the cholesterol your body needs, and the rest comes from foods you eat, especially animal-based foods like meat, dairy, and eggs.

There are different types of cholesterol:

• LDL (Low-Density Lipoprotein) – often called “bad” cholesterol because too much of it can build up in your arteries and lead to heart disease or stroke.
• HDL (High-Density Lipoprotein) – known as “good” cholesterol because it helps carry excess cholesterol back to the liver to be removed from the body.
• Triglycerides – a type of fat that, along with cholesterol, can contribute to plaque buildup if levels are too high.

A healthy balance of cholesterol is important. Too much LDL or too little HDL increases the risk of problems like atherosclerosis, heart attack, or stroke

Lowering cholesterol often comes down to lifestyle changes, though some people may also need medication if lifestyle adjustments aren’t enough. Here’s a practical guide:

1. Improve Your Diet

• Eat more fiber-rich foods – Oats, beans, lentils, apples, and vegetables help remove cholesterol from the body.
• Choose healthy fats – Use olive oil, avocado, or nuts instead of butter or margarine.
• Reduce saturated fats – Limit fatty meats, full-cream dairy, and processed snacks.
• Avoid trans fats – Often found in fried foods, pastries, and processed snacks.
• Add omega-3s – Fatty fish like salmon, sardines, or mackerel support heart health.

2. Exercise Regularly

• Aim for at least 150 minutes of moderate activity (like walking) or 75 minutes of  activity (like jogging) weekly.
• Exercise helps raise “good” HDL cholesterol and lowers triglycerides.

3. Maintain a Healthy Weight

• Even a 5–10% weight loss can significantly improve cholesterol levels if you’re overweight.

4. Quit Smoking

• Stopping smoking can increase HDL (“good” cholesterol) and improve heart health quickly.

5. Limit Alcohol

• Drink in moderation — no more than 1 drink a day for women, 2 for men — or avoid it altogether if you have high triglycerides.

6. Manage Stress

• Chronic stress may raise cholesterol levels. Try yoga, meditation, or deep-breathing exercises to help.
