Basic Information About Cholesterol

Introduction

Cholesterol is a waxy, fat-like substance found in your blood and other tissues. It's made in the liver from basic building blocks called lipoproteins. Lipoproteins are composed of proteins, fats and sugars that carry cholesterol through your body and help keep it stable for delivery to various areas where it can do its job—namely, transporting cholesterol around the body for use by cells like those in the heart and brain. When you eat foods containing cholesterol, they're converted (hydrolysed) into small particles called cholesteryl esters that then travel through your bloodstream to deliver their load of vitamin K1 and other vitamins needed to support normal hair growth (among other functions).

What is cholesterol?

Cholesterol is a fat found in our bodies, primarily as part of cell membranes. It also plays an important role in the production of hormones, including estrogen, testosterone and insulin. In addition to this role for hormones, cholesterol is also present at low levels in brain and nervous system tissue (the "brain-heart" connection).

Cholesterol can be found inside all cells except those that lack it. The liver makes all new cholesterol and stores most of what we get from food until it’s needed by other tissues such as muscles or nerves where they need it for building up their membranes walls (which contain lots of fats).

How does cholesterol work?

Cholesterol is a lipid. It’s a waxy substance that is found in your blood and is needed for the formation of cell membranes. Cholesterol also acts as an important building block for hormones, such as sex hormones and steroids.

Where does cholesterol come from?

Cholesterol is a type of fat that your body makes. It’s found in the cells of your brain, nerves and muscles. Your liver makes most of the cholesterol you need to function properly but it can also get some from food sources like eggs, nuts and seeds.

Cholesterol is made by the body for use as an essential component for cell growth (it plays an important role in forming new cells). The higher your total cholesterol levels are, the more likely you are to develop heart disease or stroke – two conditions caused by having too much LDL (bad) cholesterol in your blood stream.

Can I eat too much cholesterol?

You may have heard that cholesterol is a "bad" fat, but in reality, it's actually an essential nutrient. Cholesterol is found in foods such as eggs, red meat and fish. You need some of these foods to provide your body with the building blocks it needs to make hormones and other important substances like vitamin D and bile acids.

So what does all this mean? If you eat enough fruits, vegetables and whole grains every day (which can add up to over 500g/1lb per day), then yes—you'll get plenty of cholesterol from those sources! The majority of Americans consume too much saturated fat from animal products like meat or cheese (about 70%) as well as trans fats from processed foods; however most people don't realize how much salt we're putting into our diets either because people think salt just happens when there's no label saying "salt added".

Are there any foods that lower my LDL cholesterol level?

While there are no foods that can lower your LDL cholesterol level, you can reduce your risk of heart disease by eating a healthy diet. The following foods may help:

Omega-3 fatty acids

Vegetables and fruits

Legumes (beans)

Seeds and nuts

Do I need to avoid eggs or red meat because they contain high levels of cholesterol?

Eggs and red meat are not the only sources of cholesterol. Cholesterol is found in many foods, including fish, poultry and dairy products.

Cholesterol is a key building block of cell membranes that helps transport cellular materials such as hormones and vitamin D throughout your body. It's also needed for the production of bile acids which help digest fat in your small intestine. Bile acids are produced when certain enzymes break down fats in food into short-chain fatty acids (SCFAs).

Eat a balanced diet, exercise regularly and talk with your doctor to keep your cholesterol levels in check.

Eating a balanced diet, exercising regularly and talking with your doctor are all effective ways to maintain healthy cholesterol levels.

Eat a balanced diet: Try to eat foods that are high in unsaturated fats (olive oil, avocados), low in saturated fats (low-fat dairy products) and whole grains. Avoid foods high in trans fat like hydrogenated vegetable oils or partially hydrogenated vegetable oils used in frying at home or restaurants.

Exercise regularly: Physical activity can help lower blood pressure, raise HDL cholesterol levels and reduce the risk of heart disease by improving insulin sensitivity. The American Heart Association recommends 30 minutes of moderate aerobic activity five times per week for people who do not already have diabetes mellitus type 2; optionally 20 minutes three times per week for those who have been diagnosed with diabetes mellitus type 2; engage in muscle strengthening activities such as yoga or Pilates one time per week; perform resistance training two times per week if you are overweight but otherwise don't need any additional cardio exercise!
