Cortisol and Stress. How to Stay Healthy

Cortisol and Your Body
By Elizabeth Scott, M.S., About.com

Cortisol is an important hormone in the body, secreted by the adrenal glands and involved in the following functions and more:

•Proper glucose metabolism
•Regulation of blood pressure
•Insulin release for blood sugar maintanence
•Immune function
•Inflammatory response

Normally, it’s present in the body at higher levels in the morning, and at its lowest at night. Although stress isn’t the only reason that cortisol is secreted into the bloodstream, it has been termed “the stress hormone” because it’s also secreted in higher levels during the body’s ‘fight or flight’ response to stress, and is responsible for several stress-related changes in the body. Small increases of cortisol have some positive effects:


•A quick burst of energy for survival reasons
•Heightened memory functions
•A burst of increased immunity
•Lower sensitivity to pain
•Helps maintain homeostasis in the body

While cortisol is an important and helpful part of the body’s response to stress, it’s important that the body’s relaxation response to be activated so the body’s functions can return to normal following a stressful event. Unfortunately, in our current high-stress culture, the body’s stress response is activated so often that the body doesn’t always have a chance to return to normal, resulting in a state of chronic stress.

Higher and more prolonged levels of cortisol in the bloodstream (like those associated with chronic stress) have been shown to have negative effects, such as:


•Impaired cognitive performance
•Suppressed thyroid function
•Blood sugar imbalances such as hyperglycemia
•Decreased bone density
•Decrease in muscle tissue
•Higher blood pressure
•Lowered immunity and inflammatory responses in the body, slowed wound healing, and other health consequences
•Increased abdominal fat, which is associated with a greater amount of health problems than fat deposited in other areas of the body.

Some of the health problems associated with increased stomach fat are heart attacks, strokes, the development of , higher levels of “bad” cholesterol (LDL) and lower levels of “good” cholesterol (HDL), which can lead to other health problems!

To keep cortisol levels healthy and under control, the body’s relaxation response should be activated after the fight or flight response occurs. You can learn to relax your body with various stress management techniques, and you can make lifestyle changes in order to keep your body from reacting to stress in the first place. The following have been found by many to be very helpful in relaxing the body and mind, aiding the body in maintaining healthy cortisol levels:


•Guided Imagery
•Journaling
•Self-Hypnosis
•Exercise
•Yoga
•Listening to Music
•Breathing Exercises
•Meditation
•Sex
•Other Techniques

Cortisol secretion varies among individuals. People are biologically ‘wired’ to react differently to stress. One person may secrete higher levels of cortisol than another in the same situation. Studies have also shown that people who secrete higher levels of cortisol in response to stress also tend to eat more food, and food that is higher in carbohydrates than people who secrete less cortisol. If you’re more sensitive to stress, it’s especially important for you to learn stress management techniques and maintain a low-stress lifestyle.

Beware of Counterfeits!

I was at the grocery store yesterday and had to shake my head at all of the deceptive labels with everything claiming all sorts of things that are supposedly "healthy", but aren't really.

One of the things that really disturbed me was that I saw several examples of healthy foods in their natural state, but I saw counterfeit versions of these foods claiming that they were healthier than the original...

Yet in reality, all of these counterfeit versions were actually MUCH worse for you than the original... and they still have the balls to claim that their overly processed "junkified" versions are better.

This is food marketing deception at it's worst!

**Example #1: Product claiming "Better than peanut butter"

This product is ludicrous! I can't believe anyone would ever believe that this junk is better for them than natural peanut butter.

First of all, if you buy a good simple peanut butter (organic is best), it is usually nothing but 2 ingredients... peanuts and salt. And they don't add much salt so it's not high in sodium.

However, this counterfeit peanut butter which claimed it was "better than peanut butter" (trying to seem healthier than peanut butter based on it's label claims) had a list of junk in it you wouldn't believe. First of all, they strip all of the healthy fats out of the peanuts so that it is a "low fat" product. Ok, now you've just taken away one of the healthiest parts of the product...the appetite satisfying healthy fats that you need to control cravings and manage more stable blood sugar levels.

To make things worse, the healthy fats were replaced with 2 different types of sugary syrups as well as additional dehydrated cane juice (aka SUGAR), in addition to added refined starches.

This product has taken something as simple and natural as peanut butter, and turned it into what should really be called some sort of processed candy. Yet, they claim that it's healthier than peanut butter. And somehow they get away with deceiving people like this. Don't be their fool!

**Example #2: Product claiming to be "better than eggs".

I won't get as detailed on this one because I recently talked about this entire topic in another newsletter.

But basically, this product was just egg whites with a bunch of added chemical colorings, flavorings, and other nonsense, including fake added vitamins.

Again, this product has essentially ruined a good thing by removing the healthiest part... the YOLKS! And yes, the yolks ARE the healthiest part of the egg. Anybody that tells you different doesn't understand much about true nutrition. The important thing to look for in quality whole eggs are cage-free and organic.

**Example #3: A product claiming to be "better than butter".

This was essentially crappy margarine loaded with highly processed and deadly trans fats, yet it had the nerve to claim it was "better than butter".

Heck NO!

Even low quality butter is healthier than any margarine. One problem with butter is pesticides and hormones from improperly raised cows.

For this reason, you always want to choose organic butter, and if you can find "grass-fed" butter, then I would even say it can be healthy for you. In fact, adding a little butter to your steamed vegetables helps your body to absorb more of the vitamins and minerals in the veggies.

Also, due to the content of stable saturated fats in butter, this makes butter one of the best oils to cook with. Oils high in polyunsaturated oils are the worst to cook with due to their highly unstable nature.

And no, the saturated fat in butter is NOT bad for you!

If you found the topics in today's newsletter interesting, do your friends, family, and co-workers a favor and fwd this email to them.
