The 5 Best Sugar Free Protein Powders in 2018

Reading time: 18 minutes

What is sugar?

This may take you back to your high school chemistry class, however, here we go.

Sugar is the smallest type of carbohydrate which is absorbed rapidly by the body, and easily digested.

Further, sugars are found in most foods, and come in two different forms.

The first are called monosaccharides which are a single molecule sugar and are easily and quickly absorbed into the blood stream.

These include:

  • Fructose
  • Galactose
  • Glucose

The second are called disaccharides which consist of two molecules of sugar, which when entered into the body are broken down into single sugars.

These include:

  • Sucrose which combines glucose and fructose, and is commonly referred to as table sugar
  • Lactose which combines glucose and galactose, and is commonly referred to as milk sugar
  • Maltose which is 2 molecules of glucose, and is commonly referred to as malt sugar

Taking it one step further, sugars are then categorized into naturally occurring sugars and added sugars.

Naturally occurring sugars are those which are found in more nutrient rich type foods and as the name implies, are formed directly from the foods they are associated with.

A few examples of foods containing naturally occurring sugars include:

  • Dairy products
  • Fruit
  • 100% Fruit juice
  • Vegetables
  • 100%Vegetable juice

Added sugars, on the other hand, are generally processed and found in foods which are void of nutrients and are generally very high in calories.

A few examples of foods containing added sugars include:

  • Sugar sweetened beveridges such as soda pop, non 100% fruit drinks, and sweetened tea & coffee
  • Sweets like candy, jams, and syrups
  • Baking such as cookies, cakes, and muffins
  • Cereals sweetened with sugar

Are Naturally Occurring Sugars Better For You Than Added Sugars?

This is a debate which has been going on for many years, and the answer is “Yes, with some qualification”.

This may sound a bit vague, however, there is no, one right answer.

Like anything ingested into the body, any sugar should be taken in moderation.

Although disputed by many in the health and nutrition field, the US Dietary Guidelines state that no more than 10 percent of our daily calories from added sugars.

Many feel it should be far less.

Fructose is the naturally occurring sugar derived from most fruits and vegetables, which provides sweetness.

In its natural form, it is housed in fiber, which slows the absorption and release process by the liver, meaning that energy will be delivered over a long period of time.

Alternatively, when the fructose is removed, processed, and added back as a sweetener, the fiber component is gone meaning that it is absorbed very quickly by the liver, giving rise to an energy burst.

For this reason, eating a piece of fruit in the morning will provide sustained energy until lunch time, while a muffin or Danish pastry will provide a quick energy spike followed by a period of sluggishness.

Most foods high in naturally occurring sugars also include other vitamins, minerals, and nutrients which are beneficial to the body.

While foods high in added sugars generally are void of nutrients and have a high level of empty calories which are stored as fat.

At the end of the day, sugars are important to the body as a source of energy.

Unless you are on a highly restricted medical diet such as those who are diabetics, it is virtually impossible to avoid foods without added sugars.

That being said, the general rule of thumb is to limit the amount of foods which contain added sugars and replace with foods which contain naturally occurring sugars.

A simple starting point is to satisfy cravings for sweets with a piece of fruit, be it in the morning, or as a snack in the afternoon or before bedtime.

What does sugar free mean?

Under the US Food And Drug Administration Guidelines, a food product must contain less that 0.5 grams of sugar in order for it to be labelled “sugar free”.

Protein powders fall into this category.

When you read some of the comments below, made by customers who have used the sugar free protein powders on our list, you will see that some found the taste to be too sweet.

This is because many protein powder manufacturers use sweetening agents or sugar substitutes which are often sweeter than sugar.

The Food And Drug Administration has approved six of these agents which include aspartame, neotame, acesulfame potassium, stevia, saccharin and sucralose.

These do not add any calories and as a result, many people consume products containing these additives as a means of reducing calories.

The drawback is that many of these sugar substitutes alter the sugar receptors and can make nutritious foods taste less sweet and bland.

The net result can be a loss in interest of good food and in turn a craving for the less nutritious food flavored with artificial sweeteners.

Below is our list of 5 Best Sugar Free Protein Powders in 2018, which was a very challenging task to complete.

There are a multitude of quality sugar free protein powders on the market, however, we chose products which had absolutely no sugar as opposed to following the US FDA guidelines of less that .5 grams.

Further, we chose a cross section of both animal and plant based protein powders to appeal to both groups.
