Episode 30 – How to lower your cholesterol levels

Listen to Episode 30 here: How to lower your cholesterol levels

February 2017: the written content below has been updated to reflect new research relevant to this article.

1. The type of fat in your diet is more significant than the amount

Research has shown that when people consumed healthy levels of monounsaturated and polyunsaturated fats, they often had lower risk of heart disease and better blood cholesterol levels than those who consume low-fat diets.

Nuts, seeds, avocado, olive oil and other vegetable oils that are liquid at room temperature are heart-healthy fats. Fatty fish such as salmon contain the best sources of omega-3 fat. Aim to consume fish two to three times per week. If you don’t eat enough fish, consider taking a fish oil omega-3 supplement and/or eat hemp seeds, ground flax seeds or omega-3 eggs.

2. Fibre is good for digestive health and also reduces cholesterol

You might have heard that oatmeal and bran are good for keeping you regular, but high-fibre foods, particularly those rich in soluble fibre such as bran cereals with psyllium, reduce cholesterol.

Consume oats, bran cereals and/or beans/legumes every day. Eat at least three pieces of fruit daily and have good portions of a variety of veggies more than once a day.

 

3. Reduce trans fat and be mindful of saturated fat

Trans fats are a particularly negative class of fat found in packaged and processed foods such as deep fried items, commercial baked goods and pastries. Read food labels and be sure to limit — if not avoid — foods that contain hydrogenated vegetable oil and shortening.

Traditionally it was thought that saturated fat was harmful for heart health.  Saturated fats are found in heavily marbled meats, the skin on poultry, butter, margarine, tropical oils (coconut oil, palm oil, cocoa butter), and high fat-dairy foods such as cheese.  Newer research has found that saturated fats may or may not increase the ‘bad’ LDL-cholesterol in the body, which harms heart health. Part of the reason that there may be some conflicting results depends on which foods are being replaced for saturated fat.  Monounsaturated fats (found in olive oil, nuts and avocado) as well as omega-3 fats (found in fish) when replaced for saturated fat is beneficial for heart health.  Health depends on the quality of your whole diet, not just the type of fat or any other single nutrient.  Rather than focusing on counting grams of fat, focus first on eating wholesome foods your grandmother would recognize that contain simple ingredients.

 

4. When looking at a food label, investigate trans fat and saturated fat rather than dietary cholesterol

There is a common myth that if you have high blood cholesterol levels you should avoid foods high in cholesterol such as shrimp or eggs. There is no Canadian recommendation to eat less dietary cholesterol, nor does the Dietary Reference Intakes report by the Institute of Medicine specify a target level for dietary cholesterol.

Most people with or without high cholesterol levels can have an egg a day without influencing their blood cholesterol levels. It is far more significant to reduce trans fats and saturated fats in your diet.

5. Other lifestyle factors can make a difference

You likely already know that quitting smoking, getting enough exercise, and managing stress are also important for your heart health. Did you know that even losing 10 pounds if you are overweight can also make a difference?  While you may still have more than 10 pounds to lose, even small changes can help.
