Nutrient Timing Before, During, and After Exercise

We often hear about the importance of diet and exercise in regards to improving our health and fitness.  Did you know what you eat before, during, and after a workout may affect your exercise performance as well as possibly enhance or hinder your goals?  Energy comes in the form of calories (the macronutrients carbohydrates, protein, and fats) - if you don’t consume adequate pre-workout calories your workout may suffer.

Aim to eat a healthy meal containing carbohydrates, protein, and minimal fat at least 90 minutes prior to an exercise session.  Carbohydrates provide the body with glucose – our body’s main source of energy while protein helps slow down the breakdown of muscle.  The food you eat is fuel for your body – make it high-octane premium! 
In most cases you will not need to consume food during an exercise session lasting an hour or less.  However, it is important to stay hydrated!  Water is usually sufficient unless you’re exercising in extreme heat or participating in activities lasting more than one hour, in which case you may want to consider a beverage or snack containing glucose.  

The optimal time to replenish glycogen stores and promote muscle growth and recovery is within an hour after exercise (Suzuki, 2003).  Carbohydrates should be consumed to replenish depleted energy stores (glycogen) while protein consumption will help repair and rebuild muscle.  A glass of chocolate milk is an inexpensive and effective recovery aid after an intense strength training or high intensity workout (Denny, 2013). 
For most of us a maintaining a healthy diet will get us through our workouts and allow us to achieve better results.  Ultimately the amount of fuel needed before, during, and after your workout will depend on the intensity and duration of the exercise activity.  Try incorporating these dietary tips into your pre- and post-workout routines for more sustained energy.

If we could get every individual the right amount of nourishment and exercise, not too little and not too much, we could have found the safest way to health.

Stroke Awareness

May is Stroke Awareness Month.  A stroke is a serious medical emergency. “Stroke is the fourth leading cause of death in the United States and is a major cause of adult disability.  About 800,000 people in the United States have a stroke each year” (Center for Disease Control [, 2014, para. 2).     A stroke occurs when an artery supplying blood to the brain is either blocked or bursts. When the brain does not receive the blood it needs, it begins to die.

Some signs of stroke include:

§  Sudden numbness or weakness of the face, arm or leg, especially on one side of the body

§  Sudden confusion, trouble speaking or understanding

§  Sudden trouble seeing in one or both eyes

§  Sudden trouble walking, dizziness or loss of balance

§  Sudden severe headache with no known cause (National Stroke Association, 2014)

Use the FAST acronym to remember warning signs:

§  F = FACE   Ask the person to smile. Does one side of the face droop?

§  A = ARMS:  Ask the person to raise both arms. Does one arm drift downward?

§  S = SPEECH:  Ask the person to repeat a simple phrase. Is their speech slurred?

§  T = TIME:  If you observe any of these signs, call 9-1-1 immediately (National Stroke Association, 2014).

Stroke prevention tips:

§  If you smoke, quit. 

§  Monitor blood pressure.  High blood pressure increases the risk for stroke.

§  If you have atrial fibrillation, work with your doctor to manage it.

§  If you drink alcohol, do so in moderation.

§  If your cholesterol is high, work with your doctor to control it (National Stroke Association, 2014).

The risk of stroke increases with age, but can happen at any age.  As with virtually all medical conditions, our lifestyle choices can make a difference.   A healthy diet and daily exercise can significantly reduce the risks of stroke.
