Artificial sweeteners, which is the best option?


Artificial sweeteners are designed for those who want to reduce their sugar intake or find an alternative to refined or natural sugars. In Mexico, though there’s a high percentage of people living with different types of diabetes, the population in general loves sweets. What would be better than having sweets that maintain their sugary taste but without the actual sugar? Artificial sweeteners allow people with type 2 diabetes to indulge in their guilty pleasures without worrying about blood sugar spikes.

Few calories and a lot of sweetness

Obesity and some heart conditions, which are linked to developing type 2 diabetes, are directly related to the consumption of large amounts of sugar. The use of sweeteners with few or no calories could be a good option. However, these little packets aren’t suitable for everyone. Pregnant women, breastfeeding women, children, people suffering from migraines and epilepsy are susceptible to the adverse effects that this type of products can cause.

Different colors and different sweeteners

Sugar substitutes come in colored packets, this is because each color refers to the type of sweetener they contain.

The Food and Drug Administration (FDA) recognizes the use of aspartame, saccharin, sucralose, neotame, acesulfame-K and stevia as safe. Recently, Advantame and Swingle fruit extract, also called Luo Han Guo, were added to the list.

Beware of the dose

Although scientific opinion is quite divided, it is important to promote the consumption of natural foods and only use sweeteners when necessary and at the lowest concentration possible, whether they are natural or artificial sweeteners, with or without calories.

It is not only about counting calories, but to take care of the quality of the food. Be an informed consumer and be sure to read the labels; there are many products that misrepresent their makeup of their contents and add sugar or mix of two or more substances.
