The bitter side of sugar.



Remember this typical scene on TV? A girl has just ended a relationship and the first thing she does is eat ice cream and watch romantic movies.

Sugar has been our partner since we were little; it has been the reward, the prize and the consolation after a heartbreak.  And we wonder: Why do we love it so much? Why are we so drawn to candy or chocolate and not to other types of food?

Well, sugar consumption causes the brain to secrete substances that make us feel better emotionally.  There is also the theory that eating sugar intermittently can change your behavior, through addiction related hormones such as dopamine, creating dependency.

Let me tell you a little bit more about this character:
  • ·         Sugar began its career in the year 500 BC, in India.
  • ·         His first name was "Khanda" (does the word Candy sounds familiar?).
  • ·         It became famous when it was crystallized in SXVIII.
  • ·   His discovery changed the course of human history: new colonies were formed, increased slavery, migration and wars between countries.


In the last two decades sugar has stopped being so political and entered into the health area.  Consumption of sweetened beverages increased by 135% between 1977 and 2001 and is considered one of the causes of the world epidemic of overweight, which goes hand in hand with many diseases like high blood pressure, diabetes, depression and cancer.  

Currently 1 billion adults worldwide suffer from excess weight ... This is equivalent to all the inhabitants of the American continent!

Let's do a little calculation:

An average soda can (360ml) has 150Kcal and 40-50g of sugar which is equivalent to 5 tablespoons of sugar, if these calories are added to the daily diet ...

A can of soda a day can lead to weight gain of 6.75 kg in 1 year!

I once had a patient who was 10kg overweight.  Since his job made it very difficult to change his diet I began with the simplest strategy, I asked him to switch from soda to water.  In just two months he lost about 8kg, he could not believe that something as "harmless" as soda would increase his weight so easily.

But, unfortunately, we not only eat sugar when we add it to the coffee or have a coke.  It's amazing the amount of foods developed by the food industry, which use sugar to flavor, texture or color to food.  Click here to learn where it is hidden: 

Sounds terrible doesn’t it? Let’s do something about it… this week try to add only half of the sugar to your coffee, drink water instead of soda or just read the labels of the products you buy.  The good news is that you don’t have to resign to a bitter life.  In the next blog I will introduce a new member of the family of sweeteners, which will help you lose weight in a natural and safe way.

Before we go lets watch a sweet story...
