May is National Egg Month

Q:
May is National Egg Month.  Are eggs good or bad for you?  What are some practical approaches for incorporating eggs into my diet?

A:
Eggs were a common American diet staple up until the 1940’s due to their health benefits, accessibility (higher farm population), and economic value.  The consumption of eggs waned from the 1940’s forward due to studies linking eggs to heart disease, strokes, and high cholesterol due to their high fat and cholesterol content.

However, recent research has concluded:
         The amount of cholesterol the liver produces to be inversely related to the amount of cholesterol consumed (liver produces less cholesterol when consuming more cholesterol; and visa versa). As a result, cholesterol levels tend to stay the same or increase only slightly.
         Saturated fats have a large role in raising cholesterol levels and risk for diseases. 

The end result is the link between cholesterol from eggs and blood cholesterol is inconclusive.  Hence, the U.S. Dietary Guideline recommendations on eggs and daily cholesterol intake were updated.

Eggs have many health benefits.  They are a good source of protein, contain many vitamins, and several trace minerals and nutrients.  Here are some practical approaches for incorporating eggs into your diet:

         Consuming a whole egg a day is generally OK (yolks and whites)
         Exceptions do exist.  Limit or avoid egg consumption, consume egg substitutes, or consume the whites if:
        Your diet is already high in saturated fat or calories
        Your dealing with heart disease, have a higher risk for heart disease or stroke, or have high blood pressure
         Prepare the egg in a healthy manner
        Poach, boiled
        Avoid oil or butter when frying
        Avoid the extras (bacon, sausage, cheese, salt, etc.)

Strength Training and Low Back Pain


Q:  
The Fitness First staff encourages me to strength train my low back even when I have acute low back pain.  How does strength training help with low back pain?

A:
Low back pain is categorized as follows:
•Acute - a few days to ~6 weeks
•Subacute - ~6 to ~12 weeks
•Chronic - greater than 12 weeks

About 80% of adults experience low back pain at some point in their lifetime.  50% of people in the United States experience chronic low back pain and it is the most common cause of job-related disability and missed workdays.

How does strength training provide relief for low back pain and improve my low back health?

1.  When a low back injury occurs, strength training promotes oxygen / nutrient rich blood flow to the area to speed injury repair

2.  Helps alleviates stiffness and improves the spine’s range of motion

3.  Leads to gains in strength and muscle mass.  Gains in strength and muscle mass help stabilize the spine and reduces pain associated with poor posture

4.  Improves bone density to reduce the risk of osteoporosis and the pain associated with osteoporosis

5.  A strong stable spine reduces the likelihood of future injury or re-injury

6.  Promotes Endorphin release.  Endorphins elevate mood and lower the perception of pain

7.  Strength training and stretching the hamstrings helps provides relief for back pain

Regardless of the low back pain type, research has shown that strength training is an effective way to reduce pain, perceived pain, the level of disability, and improve quality of life.

Dehydration and Strength Training

Q:
I know hydration is important, but how does dehydration negatively impact my strength training session?

A:
The importance of proper hydration is well known.  Proper hydration supports all bodily function.  Every cell, tissue, and organ in your body needs water to work properly.  Therefore it is not surprising that dehydration can negatively impact performance in endurance sports (running), team sports (football), sports taking place in hot temperatures, or sports requiring heavy gear.

However, there is very little research on the impact of dehydration on strength / resistance training.

A study published in the European Journal of Applied Physiology evaluated the effects of dehydration on resistance training performance. Ten trained males completed two resistance training protocols under the following conditions:

         dehydration (3% of body mass) followed by rehydration preceding a full body workout
         dehydration (3% of body mass) without rehydration preceding a full body workout

The full body resistance training protocol was comprised of three sets to failure across six activities.  Resistance was based on the subject’s 12 repetition maximum, and two minutes of rest was given between each set.  Total repetitions were counted for all sets and compared between conditions.

The results showed that the males performed significantly more total repetitions when they were hydrated (average of 169 reps) versus when they were dehydrated (average of 144 reps).  On average, the males performed one to two reps less per set than when they were hydrated.  Conclusion: as little as 3% dehydration was enough to impair resistance exercise performance.

Can Processed Foods Be Part Of A Healthy Diet?


Q:  Can processed foods be part of a healthy diet?

A:

Most foods have some level of processing.  Even natural or organic foods may be processed.  The spectrum ranges from minimally processed (bagged beans, roasted nuts, frozen fruits / vegetables) to highly processed (snack foods, ready-to-eat meals, precooked meats).

In fact, some processed foods can be healthy when the processing is on the minimal end of the spectrum, provides access to healthy food not readily available,  prevents spoilage or increases food safety (pasteurized milk, canned fruits / vegetable, vacuum sealed products).

However, most diets are getting too much highly processed foods.  A 2016 study found that highly processed foods contribute 60% of calories and 90% of added sugars to American diets.  Similarly, Americans get 70% of their sodium from processed and restaurant foods.

How to limit highly processed foods?
•Read food labels
•Eat at home
•Avoid the salty six (bread, deli meat, sandwiches/burgers, pizza, soup, chicken)
•Eat fresh or on the minimally processed end of the spectrum
•Avoid sauces, gravies, salad dressings, condiments, and syrups

Winter vs. Summer Illnesses


Q:
With winter finally arriving, is it true that more people fall ill in winter vs. summer?

A:
The month with the most people sick is usually September.  The primary driver is kids going back to school and the mass spreading of germs.  Outside of September, it is generally true that the winter tends to be worse than summer for illnesses.

Some of the reasons include:
•People spend more times indoors
•People are less active in cold weather.  Less activity negatively impacts the health of the immune system
•Cold weather suppresses the immune processes that defend against infection
•Viruses stay suspended in winter air longer (when exhaled, the moisture surrounding the virus evaporates quickly, making the viruses lighter)
•The most common ailments, the common cold and influenza, are winter viruses

How to combat:
•Get outside
•Remain active and exercise consistently
•Get a flu shot
•Wash your hands frequently/cover your mouth when you cough
•Maintain proper nutrition
