Breakfast: A Very Important Meal For Your Health

Skipping breakfast because you think that one less meal through the day will help you lose weight?  Well, you may want to rethink that.  The medical literature reports that roughly 10%-20% of Americans routinely skip breakfast whether for weight management or out of convenience.

A new report on a randomized trial finds that skipping breakfast can trigger a condition referred to as insulin resistance.  It was found that skipping breakfast triggered acute insulin resistance and elevated levels of free fatty acids in nine obese, non-diabetic women, compared with a day on which they ate breakfast.

Insulin is a hormone that is produced in the pancreas and released in the blood stream in response to sugars in the blood (glucose).  Glucose is obtained from nearly all the food we eat and serves as the fuel to produce energy for every tissue of the body.  The insulin is necessary for the glucose in the blood to enter the tissues, sort of like a key in a lock.  When the body develops resistance to insulin the body is then forced to dump more insulin into the blood stream in an attempt to "open up the tissues".  Ironically this excess insulin release tends to make the tissues even more resistant, and the cycle repeats itself over and over with each skipped breakfast. The situation is not much better with a breakfast that is high in refined carbohydrates (ie, breakfast cereals) and low in proteins. 

Insulin resistance is the forerunner of type 2 diabetes and a component of the disorder metabolic syndrome.  Elevated insulin levels in the blood have also been linked to a number of other health compromising conditions.

On the days of skipped breakfast indirect calorimetry measures showed decreased energy expenditure (difficulty burning calories) and a significantly reduced respiratory quotient (a measurement of basal metabolic rate), which indicates greater fat oxidation (LDL cholesterol production).

Just 1 day of missing breakfast could do this.  It is easy to see how skipping breakfast regularly over time may lead to further metabolic problems such as chronic insulin resistance and possible progression to type 2 diabetes.

It seems breakfast is an important meal of the day, maybe more so than originally thought.  It is important to eat a balanced breakfast containing a significant amount of quality protein such as eggs or yogurt.

Watermelon's Remarkable Health Benefits

 If you are like me, this is your favorite season of the year.  Not because of the heat and humidity that we enjoy in the Midwest, but because of the abundance of fresh produce available for consumption; especially melons.   Watermelon is one of my favorite treats during the summer heat and now I can feel even better about making a meal out of water melon.

It turns out that this food that appears to be little more than sweet juicy snack in a rind, is actually quite a nutritious food.

Our friends at greenmedinfo.com have written an article based on studies they have reviewed.

Let Fruit Be Your Medicine: Watermelon's Remarkable Health Benefits

Written By: Sayer Ji, Founder

Watermelon is so much more than just a highly refreshing summertime treat. From the perspective of a growing body of clinical research, it is a truly medicinal food.
Only this month, research published in the Journal of Agricultural and Food Chemistry found watermelon juice is an effective remedy for reducing the recovery heart rate and muscle soreness in athletes who were given 500 ml of watermelon juice (16.9 oz) containing 1.17 grams of the naturally occurring amino acid L-citrulline.[1]

Additional research indicates watermelon may possess the following health benefits:

• Boosting Your Antioxidant Levels: Watermelon is exceptionally rich in lycopene (hence its red color) and other carotenoids such as lutein and beta carotene.[2] A 2003 study published in the Journal of Nutrition found that regular watermelon juice consumption resulted in significant increases in blood plasma concentrations of lycopene and beta carotene.[3] Keep in mind that lycopene has been found to have over 40 potential health benefits, and beta carotene (especially in its natural, food-complexed form) equally plentiful health benefits, adding extra significance to this finding. Also, the watermelon-induced increase in plasma antioxidant levels may lend explanation to why an epidemiological study of the Chinese found greater watermelon intake to be associated with a lower risk of cancer.[4]
  
  
• Reducing Blood Pressure/Improving Arterial Health: A 2012 study published in the American Journal of Hypertension found that middle-aged obese subjects with prehypertension or stage 1 hypertension who were given 6 weeks of treatment with a watermelon extract containing 6 grams of L-citrulline and L-arginine daily, experienced reduced ankle blood pressure and altered carotid wave reflection, an indication of improved arterial function.[5] The inability of the blood vessels to dilate and function properly is known as endothelial dysfunction, and is likely the most well-known initiating step in the pathogenesis of atherosclerosis. If watermelon can ameliorate or reverse this process, it would certainly provide a breakthrough alternative to many of the drugs used for primary prevention, such as the cholesterol-lowering statin drug class, whose side effects, numbering in the hundreds, include heart muscle dysfunction and damage.
  
  
• Increasing Plasma Arginine Concentrations: A 2007 study published in the journal Nutrition found that watermelon juice consumption increases plasma arginine concentrations in adults, proving that the L-citrulline from this plant origin was effectively converted into arginine. This is a highly significant finding because arginine has a great number of health benefits, especially for ameliorating the aforementioned cardiovascular problem known as endothelial dysfunction. There are at least 20 studies in the biomedical literature documenting its therapeutic role in improving endothelial dysfunction, but you can view over 150 potential health benefits of arginine on the GreenMedInfo database.
  
• Combatting Metabolic Syndrome: A promising preclinical study published in the Journal of Nutrition in 2007 found that watermelon pomace, a rich source of L-citrulline, significantly improved metabolic syndrome in diabetic, overweight rats.[6] This study is of particular interest because it lends support to relatively new research showing that fruit consumption is not harmful for type 2 diabetics.[7] The new study results were described as follows: " These results provide the first evidence to our knowledge for a beneficial effect of watermelon pomace juice as a functional food for increasing arginine availability, reducing serum concentrations of cardiovascular risk factors, improving glycemic control, and ameliorating vascular dysfunction in obese animals with type-II diabetes."
  
  
• Watermelon Seeds, a Rich Source of Protein:  It behooves us to mention the fact that all parts of the watermelon have something to offer. The seeds, in fact, are an excellent source of protein. A 2011 study published in the Journal of Cancer Research and Clinical Oncology found that "The good nutritional and functional properties of watermelon seed meal proteins suggest their potential use in food formulations."[8]  While seedless watermelon are far more convenient to eat, keep in mind that they can not reproduce without human intervention and so there are several good reasons to choose seedless varieties.

So, next time you are in the mood for watermelon, and are concerned about its notorious sugar content, 'weight-promoting effects,' and therefore possible diabetogenic and cardiotoxic properties – think again. Quality and moderation are the only things to make sure you are careful about when deciding to consume watermelon. Otherwise, enjoy it (remember Vitamin P(leasure))and know that it may just be as good for you as it tastes.

So enjoy the summer, enjoy your watermelon, and as always, enjoy your best possible health; naturally.

Yours for better health,
