Food Synergy – On Stage In A Kitchen Near You

   Posted by: Lita    in Nutrition

While science is continually confirming the health benefits of a fresh, natural diet, it’s quite probable very few of us are thinking of food synergy.

Food synergy is taking the stage to let us know that the way we eat fresh, natural foods affects their benefits to us.  You probably won’t find discussions of food synergy over beer and steak at your next barbeque party, nevertheless it’s an important concept for you to consider in your quest for good health.

Healthy vegetarians know that they must combine certain foods to make whole proteins and to get enough iron and other nutrients from their diet.

Consider the following examples of food synergy:

  • Providing nut allergies are not a problem then it’s time you once again enjoyed a peanut butter sandwich made with whole wheat bread for good food synergy.  Combining these two foods will give your body the essential amino acids which make up a complete protein.  While wheat alone is an incomplete source of amino acids, peanuts contain the amino acids that wheat needs to make it a complete source of protein; together, they do the job your body needs.
  • If you are not a big meat eater then your body may not be getting all the required iron.  If you lean toward a vegetarian way of life then it will be helpful for you to combine foods rich in vitamin C with plant based iron sources such as lentils, beans, soy, leafy greens like spinach, broccoli mustard and dried fruit.
  • Studies have shown that vitamin C together with the phytoestrogen found in various fruits and vegetables, whole grains, beans and soybeans work in combination  to inhibit the oxidation of LDL cholesterol (the bad one!).
  • In my house, tomatoes combined with broccoli don’t often come to mind when planning a meal.  Good food synergy says it should.  This combination may be more effective at slowing prostate tumor growth than either of them alone.
  • Natural flavonoids found in certain foods will assist in greater protection against cancer when you eat them together as compared to eating the foods individually.  Food synergy happens when the compound sulforaphane and the flavonoid polyphenol apigenin are taken together making the effect twelve times stronger than when eaten alone. You will find  Polyphenol apigenin in many fruits and vegetables such as apples, cherries, tomatoes and celery plus tea and wine also contain this antioxidant.  The sulforaphane can be found in cruciferous vegetables such as broccoli, cabbage and cauliflower.  Sounds like the makings of a delicious salad to be enjoyed with a nice glass of wine or cup of tea with dessert.

There are many more combinations that make up food synergy for your good health.  If food synergy interests you and you want to read more then you may enjoy a book written by Elaine Magee, MPH, RD titled Food Synergy.  Visit healthtopics.ca regularly for health and wellness news.

Mangosteen Fruit – Queen Or Pauper

   Posted by: Fernanda    in Nutrition

Have you noticed lately when you browse a health magazine that there is some new exotic food being featured as the “New Super Food”?   We are constantly being inundated with new information and claims.  From all kinds of exotic berries to green teas, how do we know what foods have some good medicinal qualities?

I want to feature a fruit that I’ve recently been introduced too called Mangosteen. Mangosteen fruit has been used since the beginning of mankind in the eastern world and has only recently been discovered in the western world.  Introduction of Mangosteen fruit to the western world brought with it the title “Queen of Fruits”.

Mangosteen fruit, also known as Xango, originated in Southern Asia.  This location is where Mangosteen fruit is usually grown. It grows on Asian tropical evergreen trees where the climate is relatively warm, does not resist very cold temperatures and grows at a very slow pace. When these trees are about ten years old they begin to produce small purplish fruits which bear no relation to the Mango. In Asia, Mangosteen fruit is regarded as the “Queen of Fruits” due to its delicate taste and aroma.

The “Claim to Fame” for Mangosteen fruit comes from its plentiful source of xanthones.   These are phenolic compounds with potent antioxidant properties.  Many people don’t realize that most of the xanthones are found in the rind and outer shell, not in the fruit itself.  Slick marketing has promoted this exotic fruit for sale in the form of juices at outrages prices. On the internet I found Mangosteen juice for sale at $35.00 for a 750ml bottle. In a health food store I found 1 liter of Mangosteen juice for sale at $50.00. Are these prices justified?

Wikipedia advises that when Mangosteen was analyzed for nutrient content, antioxidant strength and potential impact for lowering risk against human diseases it was discovered that the overall nutrient content was absent of important content. 

I am very wary of any food items coming from China.  There was a recall on children’s toys because of lead contamination, milk products have been contaminated with melamine which is a known toxin that has poisoned thousands of children while chickens, being fed melamine, and their eggs are likewise contaminated.

A recent issue in The National Geographic magazine talks about the Yellow River in China being so polluted that the water is unusable. Thousands of villagers are dying of cancer and other terminal illnesses because they use the water from the Yellow River.  Equipped with this knowledge I must then pose some questions: 

– If Mangosteen fruit comes from China what are the soil conditions like where it is being grown? 

– What waterways are feeding these fruits and how badly are they polluted? 

– What toxins are we putting into our bodies when we buy these exotic products?

We tend to forget our own super-foods grown right here in our own backyards. Think of  blueberries, black cherries, concord grapes, blackberries and cranberries. All of these have been proven to have excellent antioxidant properties while they lower the risk against certain human diseases. We can get these delicious foods certified organic which means we know that no pesticides have been used,

While you can purchase our own homegrown foods, for your family, at a fraction of the price of Mangosteen juice you can also rest easier with the assurance of quality coming from our own certified organic farming.  My money and my families health stays with our own superfoods!

Antioxidant Activity – No Free Ride For The Radicals

   Posted by: Fernanda    in Nutrition

We have all heard of antioxidants and how good they are for our health.  While it is true that antioxidants are good for our health, many of us don’t understand why?  Read along with me as I describe antioxidant activity, so that you can understand why it is essential for your good health. 

What is an Antioxidant?

Antioxidants are natural compounds; this means they are found in nature.  Antioxidants neutralize harmful free radicals.  What does this mean?  I will start by explaining what a free radical is, so you can comprehend antioxidant activity.  A Free radical is an atom or molecule, usually oxygen that is missing an electron (negatively charged particle).  This free radical is a highly reactive atom because it needs an electron to make it stable.

Where do Free Radicals come from?

Some free radicals are produced in your body by normal body processes such as metabolism.  Free radicals can be aggravated by stress. The more reactive and harmful free radicals are produced by many external factors including pollution, radiation and pesticides.

What do Free Radicals Do?

In your body, a free radical goes around looking for an electron and steals it from your cells.  This is damaging to your cells and if there are many free radicals in your body this will cause a great deal of harm and eventually lead to poor health.   Free radicals impair our immune system which can lead to infections, cancers and auto-immune diseases including Crohn’s, Multiple Sclerosis and Rheumatoid arthritis.  Free radicals are also responsible for degenerative diseases such as coronary heart disease and osteoarthritis.  Recent research has determined that free radicals are responsible for the aging process.

How do Antioxidants work?

Antioxidant activity is quite remarkable in that antioxidants give free radicals an electron that they so desperately need to become stable, meanwhile the antioxidants themselves remain stable.  Some antioxidants are generated in your body.  These antioxidants are called free radical scavengers, and as their name indicates they will travel inside your body neutralizing radicals as they come upon them.  Antioxidants are also found in a variety of colorful fruits and vegetables.  For a diet high in antioxidants some choices can include tomatoes, red peppers, berries (blackberries, strawberries, blueberries and cranberries) red grapes and pomegranate. 

When to Supplement with antioxidants?

Even though your body produces some antioxidants, and you get more from your diet, these are often not sufficient to neutralize the number of free radicals in your body.  As you age, your body becomes less efficient at producing its own antioxidants.  When your lifestyle does not provide enough antioxidants it is necessary for you to supplement with natural health products.  Vitamins A, C, and E have potent antioxidant activity. The supplement CoQ10 is an antioxidant that helps maintain cardiovascular health.  Melatonin, a hormone produced in your body that helps regulate your circadian clock, also has strong antioxidant activity. Melatonin has a great advantage over many other antioxidants because it can cross the blood brain barrier and eliminate free radicals found in your brain.

Do not allow free radicals to damage your cells leading to disease and the destruction of your body.   Keep your body healthy and be sure to supplement your diet with antioxidants.
