In today's health landscape, cholesterol remains a hot topic, with many misconceptions surrounding its role in our bodies. Let's delve into the essentials to understand cholesterol better and explore natural ways to maintain healthy levels.
Understanding cholesterol
Cholesterol is a waxy substance found in every cell of the body and is vital for various physiological functions. It plays a crucial role in building cell membranes, producing hormones like oestrogen and testosterone, and synthesising vitamin D. However, cholesterol levels can become problematic when they're imbalanced.
Dispelling the cholesterol myth
Contrary to popular belief, not all cholesterol is bad. In fact, the body produces cholesterol naturally, and it's essential for optimal health. The misconception arises from labelling cholesterol as solely harmful, leading to fears surrounding its consumption and a widespread misunderstanding of its role. Our bodies (liver) produce around 80% of the cholesterol and only around 20% of the cholesterol in our bloodstream comes from the food that we eat.
Foods that contribute to higher dietary cholesterol are:
red meat (pork, beef, lamb) as well as liver
processed meats (ham, sausages, viennas, smoked sausages, salami, bacon etc)
butter
baked goods (such as potato chips, cookies, pastries, cakes, muffins, containing trans fats or saturated fats)
refined grain products (white bread, tortillas, pasta, bagels)
sweet foods and drinks (for example ice cream, sodas)
alcohol
full-fat dairy (whole milk, cream, cheese)
palm oil
coconut oil
While the dietary recommendations are that no more than 10% from our daily intake of fats should come from saturated fats, and less than 1% from trans fats, it's also important to understand why our bodies need saturated fats:
Heart- prefers saturated long chain palmitic and stearic acid for energy
Cell membranes- need 50% saturated fatty acids to function properly
Liver- saturated fats protect it from the adverse effects of alcohol and some medications
Hormones- saturated fats function as signalling messengers for hormone production
Bones- require saturated fats to assimilate calcium effectively
Immune system- saturated fats prime white blood cells to destroy invading viruses, bacteria, fungi
Gut health- lauric acid, myristic acid, medium chain fatty acid in coconut oil, butter, meat work to kill bacteria and yeast in the gut.
Healthy cholesterol levels
Maintaining healthy cholesterol levels is paramount for overall well-being. While total cholesterol levels are often measured, it's essential to differentiate between LDL (low-density lipoprotein) and HDL (high-density lipoprotein) cholesterol. LDL is often dubbed "bad" cholesterol as high levels can contribute to plaque buildup in arteries, while HDL is known as "good" cholesterol for its role in removing LDL from the bloodstream. The primary role of LDL cholesterol is to transport fat-soluble nutrients (saturated fats) into cell membranes for use. But it's also important to understand that there are different types of LDL particles depending on their size. LDL particle size helps to understand whether LDL may contribute to heart disease or be protective of heart disease. Low thyroid function could also affect the LDL cholesterol levels be elevated and having a higher LDL than normal can also be genetic. It's important to lower your LDL cholesterol and increase your HDL cholesterol. Implementing the natural strategies described further below will help to increase HDL cholesterol and lower LDL cholesterol.
If you are concerned about your cholesterol levels or want to understand your cholesterol levels, it's best to talk to your healthcare provider.
When you test your blood cholesterol, it's always important to test not only total cholesterol, but also LDL-cholesterol, HDL cholesterol, triglycerides and ApoB (apolipoprotein). The last marker is a good marker to test for your risk for cardiovascular disease.
LDL to HDL ratio is good to have 3 to 1 or less (2 to 1 is great)
Triglycerides ratio to HDL is good to have 2 to 1 or less (1 to 1 is great)
If triglycerides are higher than HDL cholesterol, then it's typically a sign of insulin resistance and high fasting insulin.
Natural strategies to lower cholesterol
Fortunately, there are several natural approaches to manage cholesterol levels effectively. These include dietary changes, regular physical activity, stress reduction techniques, and incorporating specific foods and supplements known to support heart health. Getting adequate amount of fibre from foods is key to help to keep cholesterol levels normal. For men, it's recommended to get 35g of fibre a day; for women 25g of fibre a day and for children 7g + their age of fibre a day. The most fibre rich foods are legumes, vegetables, berries, fruits, whole grains, nuts and seeds.
Cholesterol-lowering and heart-healthy foods include:
Vegetables (eat them in rainbow of colours, fresh, steamed, baked)
Berries and fruits (blueberries, strawberries, honey berries, pomegranates
Legumes (beans, lentils)
Whole grains (buckwheat, quinoa, brown rice, oats)
Nuts (like raw almonds, pecan nuts, walnuts)
Seeds (flaxseeds, chia seeds, pumpkin seeds, sesame seeds, sunflower seeds)
Oily fish (SMASH)- salmon, mackerel, anchovies, sardines, herring
Poultry
Extra-virgin olive oil as well as olives and other healthy fats
Turmeric
Ginger
Fenugreek
Basil
Artichoke leaves
Hawthorn berry
Lecithin containing foods (eggs, soybeans, wheat germ)
Dark chocolate (aim for 75% and higher cacao content)- promote good brain and heart health thanks to antioxidants (polyphenols)
Contrary to common belief that consumption of eggs contribute to high cholesterol, eggs are actually known to help to increase HDL-cholesterol and lower LDL-cholesterol. Moderation is key here. As per dietary guidelines, having 0.5-1 eggs a day is part of a healthy diet.
As your liver is responsible for synthesising cholesterol as well as clearing off the body from excess cholesterol, it's important to support your liver health on a regular basis. Learn more here how to support liver health.
