Question 14

Not yet graded / 4 pts

Examine the three peanut butter labels above.   Which one do you think would be the healthiest and not spike your blood sugar? WHY?

 

Your Answer:

 

In my opinion" Creamy Natural Peanut Butter " is the healthiest choice regarding blood sugar management because it has the lowest sugar content (1g) and the lowest total carbohydrates (6g).

It has a high fat content, which helps to moderate blood sugar spikes by slowing digestion and the absorption of sugar and the best option for maintaining more stable blood sugar levels, especially important for individuals who has diabetes and who need to monitor their glucose intake.

 

Question 15
