Good Carbs, Bad Carbs…The Twenty Percent Rule!
How do you determine if a carbohydrate is deemed “fit for consumption?” “The 20% Rule” is your answer.
Since not all carbohydrates cause blood glucose levels to rise in the same way, it is recommended to avoid eating anything where sugar is greater than 20% of the total carbohydrates.
DO NOT look at the percent daily values (% Daily Value) listed on labels (usually the column of numbers on the far right) as these only illustrate what percentage of a 2000 calorie diet a particular food represents.
To follow the 20% Rule, all you need to do is look at the line listing the Total Carbohydrates & see how many grams are listed. This is easy to find as it usually is listed in bold black letters. You then figure out twenty percent of that number & check it against the grams of sugar. If the grams of sugar are greater than the number you just calculated, this is a bad carb. As an example, let’s look at an English muffin where the Total Carbohydrates are 25 grams.The easiest way to calculate 20% is to first calculate 10% (all you have to do is move the decimal point one space to the left) & double that number.
Ten percent of 25 would be 2.5, so twenty percent would be 5.0.When we read our English muffin label & find out it has 1 gram of sugar, since 1 is less than or smaller than 5, the English muffin would be a good carb choice. It’s that simple!
On the other hand, one cup of orange juice has 29 grams of Total Carbohydrates & 28g of sugar.No need to even do the math, no matter how “natural” it may be, orange juice is NOT a good choice thanks to the 20% rule. Only apply this rule when deciding if a carbohydrate is a good food choice.
Exempt from this rule would be milk & dairy products such as cottage cheese as the sugar they contain is lactose, which is a complex sugar; unfortunately, soy milk, unless the unsweetened type, always fails the 20% rule because of its high sugar content.
Next time you go grocery shopping, be sure to read the labels & use The 20% Rule.
