Are Sugar Substitutes Healthy?


Are sugar substitutes healthy? :: This question arises among people who are aware that white sugar is not a good part of healthy diet. These people then search for sugar replacement to fulfill their sweet indulgence. Fortunately, sugar alternatives are now easily found in any market. But, are these sugar substitutes really healthy alternatives?

Let's have a minute to look a little bit closer to these sugar alternatives and see which one   is better to take or better to avoid.

Artificial Sweeteners

Americans are now consuming over 20 pounds of artificial sweeteners per person/year.
The word "artificial" indicates that these sweeteners are human-made chemical compound instead of coming by nature. They don't contain essential nutrients like vitamin or mineral. They're also very low in carbohydrates and calories.

Although the US FDA has mentioned that artificial sweeteners to be Generally Regarded as Safe (GRAS) for human consumption, they add no nutrients to our diet. That’s the reason why they may not be a healthy choice.

In fact, many researches about artificial sweeteners had found relation between consuming them with many health problems, including cancer. On the other hand, many health professionals tend to agree that these sweeteners are a good choice for diabetics, because they don't cause spike on blood sugar.

Example of artificial sweeteners are aspartame (Equal, Nutra Sweet, Spoonful), Sucralose (Splenda) and Saccharin (Sweet N' Low) .


High Fructose Corn Syrup

High Fructose Corn Syrup is made from corn starch which is further processed to yield glucose. An enzymatic processing is then carried out to convert it into fructose. Pure corn syrup is then mixed to produce the desired sweetness.
The most frightening fact about HFCS is probably the mercury contamination. This fact is published in scientific journal, Environmental Health. This study revealed that almost 50% of commercial HFCS samples from brand-names food and beverage products had been tested positive for heavy metal mercury.
Mercury is toxic in all its forms and causes a wide range of adverse health effects.
But how come there is heavy metal like mercury get in the HFCS?
One of ingredient used to produce HFCS is caustic soda, which apparently most of them was produced in industrial chlorine plants using the mercury cell (Castner-Kellner process). This may be the reason why mercury can contaminate the HFCS.


Besides of its dangerous mercury contamination, HFCS itself does not really contain any nutritional value in its syrup confection.

According to US Department of Agriculture, one tablespoon of corn syrup contains:
0 grams of fat
2 mg of sodium
14 grams of carbohydrates
15 grams of sugars
0 grams of proteins
0 grams of dietary fiber
0 grams of iron
0 grams of vitamin A and C.

Many experts had seriously warned to avoid consuming HCFS because it does not only lack of nutritional value, but worse; it will endanger human health.

Natural Sweetener

-          Maple Syrup or Maple Sugar
Maple syrup made from maple tree sap. Maple sugar is crystallized maple syrup. Maple syrup has a high glycemic index (GI of pure maple syrup is 54, while flavored maple syrup is 68), which can cause blood sugar to rise.

-          Agave Nectar
Agave syrup comes from the sap of the Maguey cactus. It consists of 56-92% fructose, while the rest is mostly glucose. Agave nectar is chemically converted fructose, which is more readily turned into triglycerides and fat than sucrose. A rise of blood triglycerides levels may lead to heart disease.
Nevertheless, agave has a low glycemic index (30) so it won't cause any significant rise of the blood sugar levels. It has also trace amounts of minerals such as calcium, potassium, magnesium and iron.

-          Honey
Honey is an invert sugar formed by enzymatic activity from nectar. It is a combination of fructose, sucrose, glucose and maltose. It does contain trace amounts of vitamins and minerals and is believed as alternative medicine for certain disease.
However, it is a high glycemic sweetener (commercial blends of honey was reported to have GI value of 58 to 69), which should be avoided by those who have diabetes.

-          Stevia
Stevia as sweetener was made from the leaves of Stevia rebaudiana. This herb has been used as sweetening agent in South America for centuries.
Stevia has few or no calories and 200-350 sweeter than common sugar. The glycemic index of stevia is zero because it can’t be absorbed by intestines.
The FDA has not approved stevia in its whole-leaf or refined forms because it may be risky to kidney, heart and reproductive systems.

-          Coconut Sugar
Coconut sugar was made from coconut sap that is tapped from certain part of coconut flower. The sap is then evaporated to remove the moisture content. The end result is coconut syrup which can be molded to make blocked coconut sugar. It can also be crystallized or remained in its liquid form (this product is also known as coconut nectar).
Coconut sugar has some overplus compared with other sugar replacement;
1.      It has a low glycemic index (35).
2.      It’s rich with nutrients by nature. Many studies have shown that coconut sap contains vitamin C and B, amino acids as well as essential minerals.
3.      It undergoes very low process (evaporation) without adding preservatives or bleaching agent.
4.      For some people, it has a great caramel taste.
Coconut sugar has been claimed as one of the best natural sugar sweeteners that is recommended as sugar substitutes.
However, there are some points you should put into consideration when deciding to use this one;
1.      Some manufacturers may blend coconut sugar with common cane sugar. Check the label and make sure it’s 100% coconut sap.
2.      Some manufacturers may add sodium metabisulfite as preservatives and bleaching agent to make the appearance better. Nevertheless, the existence of sodium metabisulfite can be detected by the taste of sugar (little bit salty). Check the label and do own research on coconut sugar’s supplier or manufacturers.
3.      Coconut sugar is not the same as palm sugar. Palm sugar was made from sap of other palmae plant like Arenga pinnata or Borassus flabellifer. Palm sugar has different nutrient contents with coconut sugar.
