Plant sterols are also called “phytosterols” (phtyo means plant). They’re like cousins to cholesterol because they have a similar structure, and are found naturally (in tiny amounts) in plant-based foods – such as fruits, vegetables, nuts, grains and vegetable oils.

If you have high blood cholesterol, plant sterols may be beneficial because they’ve been shown to decrease the levels of “bad” LDL cholesterol (Low Density Lipoprotein cholesterol) – this is the type of cholesterol that is a risk factor for heart disease.

In the body, plant sterols partially block the absorption of cholesterol. The cholesterol gets removed as waste (i.e. in our feces) which then results in an overall lower level of LDL cholesterol in your blood.

So, how much plant sterol is needed for this benefit? Research shows that eating 2 grams (2,000 milligrams) of plant sterols every day can lower LDL cholesterol levels by 8-10%. This amount is nearly impossible to get with regular foods since a typical healthy diet only contains about 200-400 milligrams of plant sterols.

To get 2,000 milligrams of plant sterols a day, you’ll need to consume foods and beverages that are fortified with plant sterols. In Canada, foods fortified with plant sterols include mayonnaise, margarine, salad dressing, yogurt, yogurt drinks, vegetable juice and fruit juice. A serving of these foods may contain up to 1 gram (1,000 milligrams) of plant sterols, so read package labels to check the exact amount. Plant sterol supplements are another option.

Plant sterols from food and / or supplements are not a substitute for a heart healthy diet or cholesterol-lowering medications. Always check with your doctor first before consuming foods or supplements with plant sterols because your medications may need to be adjusted.

You’ve probably heard of high blood cholesterol, but have you heard of high blood triglycerides?

Cholesterol and triglycerides are important measures of heart health.  Both cholesterol and triglycerides are different types of lipids that circulate in the blood, but elevated levels of both can raise your risk for heart disease. Here is a rundown of the difference between cholesterol and triglycerides, and why they matter for your heart health.

Definitions & Why it Matters

Cholesterol is a waxy, fat-like substance found in some foods and in your blood. Your liver makes most of the blood cholesterol and it produces enough for your needs. Cholesterol is part of every cell in your body and some hormones. Cholesterol is needed to help your body digest and absorb fat.

Too much cholesterol in the blood can build up inside arteries, forming what is known as plaque. Large amounts of plaque increase your chances of having a heart attack or stroke.

Triglycerides are a type of fat found in some foods as well as in your body. Triglyceride is a term that describes the structure of a fat, which is made up of 3 fatty acids and a glycerol backbone. (See summary chart for diagram). When you eat, your body converts any excess calories you don’t need to use right away into triglycerides for a longer-term energy source. Triglycerides are mostly stored in your fat cells and are commonly deposited beneath the skin and around some internal organs. Some triglycerides circulate in the blood.

You need some triglycerides for good health. But high triglycerides might raise your risk of heart disease. High blood triglycerides may contribute to hardening of the arteries or thickening of the artery walls (arteriosclerosis) — which increases the risk of stroke, heart attack and heart disease.

What’s the best way to lower your blood cholesterol and triglycerides?

Healthy lifestyle choices are KEY low lower the risk of heart disease.  Bringing your blood cholesterol and triglyceride numbers down takes effort and commitment. Here are some things you can do.

Top 5 ways to lower cholesterol:

  • Choose foods that are lower in saturated fats like fish, lean cuts of meat and poultry, and lower fat milk and dairy products.
  • Eat a variety of heart healthy foods. Choose more vegetables, fruit, high fibre whole grains, beans, chickpeas, lentils, soy products, nuts and seeds.
  • If you smoke – quit all types of smoking.
  • Be physically active on most, preferable all days of the week.
  • Maintain a body weight that is healthy for you.

Top 5 ways to lower triglycerides:

  • Limit fast releasing carbohydrates like candy, sweet snack foods, and baked goods made with highly refined white flours.
  • Limit how much alcohol you drink. Even small amounts of alcohol can raise triglycerides.
  • Include heart healthy fats such as olive oil, fatty fish, nuts, seeds and avocados.
  • Focus on boosting veggies and high fibre foods such as beans, lentils, chickpeas, seeds and whole grains every day.
  • Enhance your fitness routine. Find moderate to vigorous activities you enjoy (such as cycling, running, brisk walking, swimming, etc.) and aim for at least 150 minutes per week which is about 40 minutes 4 times a week or 50 minutes 3 times a week.

Dare to Compare: Chia Seeds versus Flax Seeds

Ever wonder what the difference is between these two tiny seeds?

What are they:

chia seeds

Chia seeds are tiny white or black seeds that look like poppy seeds. They were first cultivated by the Aztec tribes in Mexico.

flax seed 2

Flax seeds are flat, yellow or brown, oval shaped seeds that are about the size of a sesame seed. Brown flax seeds are grown right here in Canada, mainly in the western Prairies.


Nutrition and health benefits:

Chia seeds are filled with insoluble fibre. When mixed with water or fluids, chia seeds expand and swell to form a gel. Chia seeds are a source of heart-healthy plant-based omega-3 fats, calcium, iron, magnesium, zinc and selenium. When it comes to fibre, calcium and selenium, chia seeds win over flax seeds. (See comparison chart below.) Studies show many benefits to including chia seeds as part of a healthy diet, such as a reduction in blood cholesterol levels and the prevention of constipation.

Note: Chia seeds can thin your blood, as well as interact with medications and blood thinners such as Warfarin/Coumadin. If you are taking any types of these medications or any type of blood pressure medications, then please avoid chia seeds and talk to you doctor.

Flax seeds are hailed as a super source of plant-based omega-3 fats which is an important nutrient to help lower the risk of heart disease. With a similar nutrition profile to that of chia seeds, flax seeds are also a source of zinc and selenium, and a good source of magnesium. Flax seeds are one of the best food sources of lignans, which are a type of plant-based estrogen. Research suggests that these lignans may play a role in protecting against breast cancer.

How to include in a healthy diet:

Both chia seeds and flax seeds have a nutty flavour and can be easily added to your favourite dishes.

Chia seeds – Sprinkle into smoothies, cereal, yogurt, soups and salads. Try our yummy Chia Seed Pudding recipe or mix some chia seeds into muffin batter. Store chia seeds in a dark, cool place for a few months.

Flax seeds – Sprinkle over cereal or yogurt, or add them to pancake batter and meatballs. Whole flax seeds can be stored at room temperature for up to one year. Ground flax seeds are easier to digest. Grind your own flax seeds in a coffee grinder or food processor. Store ground flax seeds in an opaque container for up to three months.

Dietitian’s Tip: Enjoy a variety of foods and include chia seeds and/or flax seeds when you can. Leave us a comment and tell us how you love to use chia and flax!

Health Canada announces three new health claims

Health pic from Sue June 1, 2016

In May 2016, Health Canada announced three new health claims:

1. EPA & DHA and blood Triglyceride Lowering

2. & 3. Polysaccharide Complex (Glucomannan, Xanthan Gum, Sodium Alginate) and Blood Cholesterol Lowering and Reduction of the Post-Prandial Blood Glucose Response

Foods containing the healthy fats EPA and DHA (0.5 g combined) may now carry a new health claim stating their potential triglyceride-lowering benefits. For example, a permitted claim might read, “85 g (1/2 cup) of canned pink salmon supplies 40% of the daily amount of omega-3 EPA and DHA shown to help lower triglycerides.”

Aside from that primary statement, appropriate products can also carry the additional statement “EPA and DHA help reduce/lower triglycerides,” Read the detailed info here.

The food ingredient that is the subject of two new health claims is a soluble and viscous dietary fibre (polysaccharide complex of glucomannan, xanthan gum, sodium alginate) sold under the brand name PGX® (PolyGlycopleX®). Researchers studied the carbohydrate quality of foods with PGX using the glycemic response, glycemic index. The benefits of added fibre in the form of PGX helped help lower blood cholesterol and moderate the blood sugar rise after a meal. Sample claim: “The consumption of the 5 g of PGX® provided with 1 cup (30 g) of cereal helps reduce blood glucose rise after a meal containing carbohydrates.”
The summary of assessment is available online.

Please feel free to contact us with your questions on food labelling and claims.

Health Canada approves new health claim

Health Canada has recently permitted a new health claim linking the consumption of psyllium fibre to a reduction of blood cholesterol.   A sample claim is: “Psyllium fibre helps lower cholesterol, a risk factor for heart disease. 1 cup (30 g) of Brand X cereal with psyllium supplies 50% of the daily amount of fibre shown to help lower cholesterol.”  The “daily amount” is 7 g of psyllium fibre. To make this claim, the food must contain at least 1.75 g of psyllium soluble fibre per serving size as well as meet other specific nutrient criteria.

According to Health Canada, increased psyllium intake could be beneficial for adults who have normal or high blood cholesterol levels. Psyllium is a grain similar to wheat and oats, and is a concentrated source of soluble fibre.

Implications for your business: Only a few breakfast cereals currently contain psyllium fibre, but you can bet we’ll be seeing more psyllium-containing products hit the grocery shelves soon.
