Finding out your cholesterol is high is difficult news to receive, and for or some people it brings up guilt, shame, or frustration. I’m Jacqueline Stickel, a Registered Dietitian with a focus on heart health including cholesterol management. In this blog post I discuss what cholesterol is, how it relates to health, and I have 5 nutrition strategies for managing cholesterol.
Cholesterol is a type of fat found in your blood. Blood tests can help to identify the balance of cholesterol. Blood tests may include: total cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides, non-HDL, and ApoB.
Too much LDL and/or triglycerides circulating in the blood can lead to buildup of fatty deposits in the artery walls called plaque, which increases risk of heart attack and stroke. Other markers that may be used include:
Dietary patterns contribute only ~20% of the cholesterol in the body, with the other 80% made by the liver. This means that cholesterol levels are largely determined by genetics and a person’s liver production. However, lifestyle factors that contribute to increased cholesterol include: smoking, physical inactivity, and dietary factors such as alcohol consumption, high consumption of saturated and trans fats, and excess sugar intake.
Treatment for high cholesterol includes lifestyle changes and/or medications called statins. The goal is to reduce the risk of heart attack or stroke.
Lifestyle changes involve adjusting dietary intake, increasing physical activity and stopping smoking.
Before deciding on a treatment option, ask yourself, “what is my capacity for making lifestyle changes to lower my cholesterol?” There is no wrong answer, and it’s important to consider your barriers, overall risk, and all treatment options available. Medications are often accessible, and sometimes lifestyle modifications are not going to be effective enough.
1) Have regular meals (and snacks) throughout the day.
Eating regularly supports energy levels and maintains healthy blood cholesterol levels. Also, skipping meals earlier in the day, followed by eating larger meals later in the day to compensate, can raise LDL cholesterol.
2) Diversify proteins.
Include a variety of protein sources in your diet. Adding plant-based proteins such as beans, lentils, nuts, seeds, and soy foods improves cholesterol. For example:
3) Eat foods high in soluble fibre.
Soluble fibre is found in plant foods. Because it is not absorbed in the intestine, it binds cholesterol and removes it from the body. When increasing soluble fibre, do so gradually and drink more water to avoid discomfort and excess bloating. Foods containing soluble fibre include: fruit, vegetables, whole grains, and legumes. For example:
Whole grains including whole grain bread, oatmeal, barley, and quinoa.
Legumes including soybeans (e.g. tofu, tempeh or edamame beans), beans, lentils or chickpeas. Choose canned options for convenience
4) Eat more unsaturated fats.
Regular intake of unsaturated fats lowers LDL cholesterol. Foods high in unsaturated fat include: oily fish (e.g. salmon, trout, sardines, mackerel, tuna herring), vegetable oils (e.g. olive, canola, sunflower), avocado, and nuts and seeds. For example:
5) Reduce alcohol intake.
Alcohol increases total and LDL cholesterol as well as triglyceride levels. Canada’s Guidance on Alcohol and Health recommends reducing alcohol use, and demonstrates the risk for heart attack or stroke is associated with weekly alcohol consumption:
The good news is that any reduction in alcohol intake lowers health risk.
