Lower CholesterolHow do you increase your intake of plant sterols?
Plant sterols and stanols are not found at high levels in foods. For this reason food manufacturers have found ways to fortify foods with plant sterols and stanols.
Some foods that are fortified with plant sterols and stanols include spreads, juices, milk, breads, salad dressings, and yogurt.
Heart HealthPhysical Activity Benefits – Why should you be active?
Okay, in the previous two posts, we’ve covered how much physical activity is needed and I mentioned different intensities requiring different time commitments.
A simple measure of your workout intensity is the talk test. If you can carry on a conversation while taking a breath every 3-4 words, you’re probably at a moderate intensity level. If you are working out hard enough that you can only say a few words and in order to say more you have to stop to catch your breath, you’ve most likely hit a vigorous activity level.
What physical activity benefits can you expect to see by being more active this year? Here are a few:
- Improved fitness and bone health.
- Decreased coronary heart disease, stroke, high blood pressure, type 2 diabetes, and colon and breast cancer.
- Less depression.
- Fewer falls and better cognitive ability for older adults.
- Better pain management, function, and quality of life if you suffer from arthritis.
Tired of changes that don't last?
All right, now don’t just read this without taking action. Look at the upcoming week. Where can you add a walk or extra trip to the gym to boost your activity level closer to the desired 2 ½ hours per week?
There are 1440 minutes each day. Only 30 of them need to be active!

Lower CholesterolLower Cholesterol – How much omega 3 do you need to lower cholesterol?
Increasing the amount of omega-3 fats in our diet and decreasing the amount of omega-6 is beneficial in reducing your risk for heart disease. Most American’s consume a high omega-6 diet, with omega 3 being a common deficiency. Omega 3 deficiencies and the imbalance between omega 3 and omega 6 intakes have been linked with serious conditions, including heart attacks. Successfully maintaining a ratio of 4:1 to 1:1 omega 6 to omega 3 will help lower cholesterol levels and control high blood pressure.
Now, how much omega 3 do you need to add?
This is under debate and more research is being done. Right now the range experts recommend is from 500-2000 mg/day. Here are the current American Heart Association (AHA) recommendations.
The AHA recommends that individuals without heart disease eat a variety of fish twice a week, use heart healthy oils (flaxseed, canola, soybean oils), and consume flaxseed and walnuts.
For individuals with heart disease, the AHA recommends 1 g of EPA (eicosapentanoic acid) + DHA (docosahexaenoic acid) daily, preferably from fatty fish.
The AHA recommends 2 to 4 g of EPA + DHA daily, under physician’s care only, for individuals that need to lower triglycerides. High doses, > 3 grams/day, can result in excessive bleeding. (Do not self medicate! Talk to your doctor before supplementing greater than 2 grams.)
Omega 3 Content of Different Foods
- Wild Salmon, 4 oz. 1700 mg (DHA 700 mg, EPA 400 mg)
- Tuna canned in water, 4 oz. 300 mg (DHA 200 mg, EPA 50 mg)
- Cod, 4 oz. 600 mg (DHA 160 mg, EPA 50 mg)
- Flaxseed, 1 Tbsp. 1000 mg (ALA – alpha–linolenic acid – 1000 mg)
- Soybeans, dried, cooked ½ cup 500 mg (DHA/EPA 250 mg, ALA 250 mg)
- Walnuts, 1 oz. 2570 mg (ALA 2570 mg)
- Pecans, 1 oz. 280 mg (ALA 280 mg)
- Wheat germ, ¼ cup 210 mg (ALA 210 mg)
- Canola oil, 1 Tbsp 1300 mg (ALA 1300 mg)
- Olive oil, 1 Tbsp 100 mg (ALA 100 mg)
Now, there’s a reason I included details on amounts of ALA, DHA and EPA for each omega 3 source. Right now, DHA and EPA have a greater link with lower cholesterol levels, lower triglycerides, and higher HDL levels than ALA. The body is able to convert ALA to EPA and DHA, but the conversion rate is low; therefore, it is best to include high DHA and EPA sources in your eating plan.
Eight steps to lower your cholesterol
My recommendation:
As a preventive measure and to promote lower cholesterol and blood pressure control, I recommend eating fish twice a week, select a supplement that will provide you at least 1000 mg of omega 3 fatty acids daily (choose a good source of DHA and EPA), and use ground flaxseed when appropriate in your meal preparation.

Heart HealthPhysical Activity – How much do you really need?
As I previously mentioned, The Health and Human Services Department sets physical activity guidelines after reviewing a good decades worth of research related to physical activity and health.
This report encompasses everyone from the age of 6 and up. Let’s go into a little more detail on the adult guidelines.
Adult Physical Activity Guidelines
- All adults should avoid inactivity. Any type of activity is better than nothing. Adults who include activity as part of their everyday life gain some form of health benefit.
- To see substantial health benefits, include at least 150 minutes (2 ½ hours) per week of moderate-intensity activity. If times a factor, you can see the same benefits by bumping up the intensity and being vigorously active 75 minutes (1 hr. 15 min.) each week.Yes, it is still okay to break your activity into chunks.For example, if your schedule doesn’t allow 30 minutes at the gym, you can include a 10 minute brisk walk during lunch break to count towards the goal of 150 minutes for the week. However, workout segments less than 10 minutes in length are not as beneficial.
Also, the most benefit is seen by spreading your activity throughout the week. If you’re tempted to hit the gym for a power workout session on a Saturday for 2 ½ hours, that is not as beneficial as 30 minutes of activity 5 days out of the week. But, remember, any form/amount of activity is better than nothing!
- If you want to take things to the next levels, more extensive health benefits are seen when activity is increased to 300 minutes (5 hours) per week of moderate intensity activity or 150 minutes of vigorous intensity aerobic activity.
- Don’t forget strength training! You want to include all major muscle groups on two or more days each week. Especially beneficial as we age and see a decline in metabolism (and corresponding weight gain) if muscle mass is not maintained.
Now, don’t let yourself be overwhelmed and give up without even attempting to meet these guidelines. Activity does not have to be hard or expensive. You can walk your dog, go dancing, climb the stairs at work, mow the lawn, and go to the gym. There are many, many options available to get 2 ½ hours of physical activity every week.
