Final answer:
A patient with diabetes allowed 60 grams of carbohydrates for lunch can consume four portions of carbohydrate foods since one carbohydrate exchange equals 15 grams. Carbohydrates are vital in managing blood sugar levels to maintain homeostasis and control the disease.
Step-by-step explanation:
A patient with diabetes who is allowed 60 grams of carbohydrate for lunch is recommended to consume four portions of carbohydrate foods, as one carbohydrate exchange (portion) is typically considered 15 grams of carbohydrates. Therefore, 60 grams of carbohydrates divide evenly into four 15-gram portions.
Carbohydrates are an important part of a diabetic individual's diet and need to be monitored closely to manage blood sugar levels effectively. This is important for maintaining homeostasis and preventing disease progression. Understanding the conversion between grams of carbohydrates and carbohydrate portions helps patients plan their meals according to their dietary allowances.
