Overview
The food we eat contains a variety of molecules including carbohydrates, lipids, proteins, and nucleic acids. The nutrition label or nutrition facts on food packaging tells us some information about the types of molecules found in food we eat. For this discussion board assignment you'll need to find one packaged food item in your home with a nutrition label for you to analyze. This is a graded discussion assignment worth 5 points.

2 post need to be reply : First post : Abdul ： 1. What is the nutrition food label that you are analyzing?
I am analyzing the nutrition label for Lay’s Classic Potato Chips.
2. Carbohydrates Information
Dietary Fiber: 1g
Sugars: less than 1g
These values make sense for Lay’s Classic Potato Chips. Potatoes naturally have some sugar in them, so seeing less than 1g of sugar in the chips is expected. Also, there isn’t much fiber because the potatoes are peeled before being made into chips. Most of the fiber in potatoes is in the skin, so peeling them removes a lot of it. Chips are not usually thought of as a high-fiber snack, so having only 1g of fiber is normal for this type of food.
3. Protein Information
Protein: 2g
The protein content was unexpected. After doing some research I learned potatoes have a small amount of protein in them, and that protein stays even after the potatoes are sliced and fried into chips. Lay’s chips are not a food that people eat for protein, so it makes sense that the amount is low. However, it’s nice to see that even a snack like this still provides 2g of protein per serving.
Second post: Betina ：1. I'm analyzing Fig and Olive Crisps from Trader Joe's.
2. Carbohydrates:
Total carbohydrate: 16 g (6%)
Dietary fiber: 1 g (4%)
Total sugars: 7 g
Includes 4g added sugars (8%)
This is expected since this product has figs, which are naturally high in sugar. Sugar cane is also included in the ingredients list. I can also see that the dietary fiber content is low because the product is processed.
3. Proteins: 2 g
This is expected because this product is simply a cracker, not a high-protein food, so the low protein content makes sense. I think the 2 g of protein comes from buttermilk.
