Part A
Brianna's doctors advise her to eat no more than 30 grams of carbohydrates per day for her snacks. Because dietary fiber
doesn't negatively affect blood sugar levels, she doesn't need to count it toward her carbohydrate total. If Brianna eats
two servings of each of these foods, will she fall under her doctor's recommended limit for her snack? Explain your
reasoning

Yes she will fall under her doctor's recommendation because she is taking prescribed amount of carbohydrate in one serving which can affect her blood sugar level and dietry fibre will have no effect on sugar level so separate portion can be taken.

Explanation:

Dietary fibres are also carbohydrates called cellulose which is not digested in our bodies. The addition of cellulose is just for adding roughage to the diet as it provides bulk to the diet.

The carbohydrate intake is very important in the meal plan as it readily provides energy. The glucose is the most easily used form of energy from the body in comparision to fat and proteins. The energy yield is 4 calories per 1 gram of carbohydrates.

The recommendations by doctor to Brianna is to have 30 grams of carbohydrate and can have dietry fibre in different portion. Thus, if she eats two servings for the diet she is following the instructions.

The dietry fibre has no effect on her sugar level but carbohydrate increment will cause raise in sugar level as insulin production gets down in diabetics and not using the carbohydrate as fuel.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
