Types of Carbohydrates Types of Carbohydrates
Simple carbohydrate foods
cause large and rapid changes in blood
glucose levels on ingestion ( a rapid rise,
followed by a rapid and often greater fall).
Complex carbohydrate foods
more nutritious foods;
digestion and absorption are slower, producing
a flatter and more sustained blood glucose and
insulin response.

Check the color (clear, pale yellow),
frequency and volume of urine.
Urine color should be pale ( not clear) and frequent.
Certain foods and vitamin supplements can change urine color.

Ex: Drink contains about 14 grams of sugar in a 240ml bottle.
14 grams / 240 ml = 0.058 x 100%
= 6%
= 6grams/100ml
Drink contains about 14 grams of sugar in a 240ml bottle is equivalent to about 6grams per 100ml or 6%
