Many of smoothies that are sold in fast food establishments in the United Kingdom are cocktail of chemical additives, mainly developed by experts to emulate the taste and smell of natural ingredients to replace them. A recently published book in this country under the title "Chew on this" says that.
Eric Schlosser, author of the book, says that the tendency to replace natural products by additives is even more pronounced in food for children. According to Schlosser, companies seek to replace the natural acidity of many fruits and vegetables by appealing sweet taste to palates, like the children, not sufficiently developed.
For example, the typical strawberry milkshake has, according to the book, 13 primary ingredients: milk fat, sugar, sweet whey, corn syrup, high fructose, guar gum, mono and diglycerides, cellulose gum, sodium phosphate, citric acid, carrageenans, E-129 and a strawberry flavor.
The "artificial strawberry flavor" is, in turn, 47 non nutritious ingredients such as acetate, amyl butyrate and valerate, butyrate, valerate and ethyl nitrate, isobutyl butyrate, benzoate or Phenethyl alcohol.
Nigel Denby, a nutritionist from the British Dietetic Association, says that if these shakes are consumed daily, have health risks. "Fresh fruit is much healthier because it contains fiber, antioxidants, vitamins, minerals and much less added sugars," says Denby.
