No matter how good a food or meal is for you, the likelihood of consuming it on a regular basis is low if it doesn’t taste good. When creating IsaLean Shakes, the taste was given careful consideration. There are no artificial flavourings or sweeteners added to enhance the flavour of any Isagenix product. IsaLean Shakes include only natural flavourings

Natural Colours as Ingredients
Colour influences flavour – we associate strawberry flavour with red, orange flavour with orange and grape flavour with purple. When using colours in foods, any use of artificial colour or artificial food dye must be clearly labelled as required per labelling guidelines (1). The use of natural colours, however, are not labelled as such as the term might be interpreted to mean that the colour is naturally occurring in the food itself.

However, unlike the complexity that exists with natural flavours, natural colours are generally present as one or only a few ingredients so these are listed out individually. Among these might be saffron or turmeric for yellow, tomato concentrate or lycopene for red, caramel made up of heated sugar for brown, or purple carrot extract for purple.

Natural Flavours as Ingredients
Based on its legal definition, natural flavours used as an ingredient in a food must consist of only aromatic compounds that are found in nature (1). Natural flavours can be derived directly from a foodstuff in the form of a spice, plant extract, essence, essential oil, or a distillate. They can also be a product of a foodstuff such as from after being subjected to use of enzymes, fermentation, roasting, or heating.

There more than 1200 different natural flavour aromatic compounds that can be used in various combinations in food (1). Most of these natural flavours are identified by their chemical names. Examples include benzaldehyde for wild cherry or almond, ethyl butyrate for pineapple, methyl anthranilate for a grape, and methyl salicylate for wintergreen (1).

The number and complexity of these compounds to produce a signature flavour are why they are all individually combined with the term natural flavours on a label of a packaged food. The term helps to inform customers of the function of these ingredients – reducing confusion that may occur from an actual listing of their chemical names or underlying sources.

Natural Sweeteners as Ingredients
Carbohydrates, which include sugars, are the preferred source of fuel for your brain, muscles, and immune system. However, a high dose of refined sugars can cause blood sugar to spike and then crash, leaving you feeling fatigued, hungry, and unsatisfied.

To help stay energized yet keep blood sugar in check, it’s important to choose meals that are known for their low glycemic response. For example, IsaLean Shake is shown to be low-glycemic referring to the slower rate that the carbohydrates are absorbed due to the proper balance and presence of fat, fiber, and protein and has only about as much sugar as ½ an apple or a small peach.

  • Fructose: “Fruit sugar,” or Fructose is found naturally in fruits and vegetables, and unlike other sources of simple sugars it helps contribute to a low-glycemic profile. In addition, fructose is a little sweeter than other sources of sugar, providing a naturally sweet taste with less use of sugar overall.
