Figuring Out Food (Part 1-3)

 Jiff Creamy Peanut Butter

  • I chose this item because I have been implementing peanut butter into a lot of my meals recently. I used to try and stay away from peanut butter because of its high fat content but I do have to admit that I do enjoy peanut butter a lot. I understand that in general, peanut butter contains a variety of nutritional value. I would like to understand a little more about it

  • I don’t necessarily understand all of its’ nutritional value that are on the label. I have also been eating organic peanut butter recently even though the Jiff creamy peanut butter may be my favorite. But I did notice the additional ingredients on the Jiff brand and even non-organic peanut butter that would explain the difference in texture. I am not too sure how beneficial or detrimental those additional ingredients are. I am still not too sure about the differences with saturated and trans fats along with the implemntations of added sugars. I am wondering if the added sugars add any caloric value.

What is Protein?
-Protein is a macronutrient essential for building and repairing tissues, as well as for various metabolic functions in the body. It's composed of amino acids, which are often referred to as the building blocks of protein.

How much protein is this food item contributing to the % DV? What does that mean?
-Jiff Creamy Peanut Butter contributes 14% of the Daily Value for protein per serving.

What ingredients are contributing the protein?
   -The primary ingredient contributing to the protein content in Jiff       Creamy Peanut Butter is roasted peanuts. Peanuts are naturally rich in protein, which makes them the main source of protein in peanut butter.

    How many calories in your food item are due to protein?
    -Calories from protein = 7g × 4 cal/g = 28 calories. Therefore, 28             calories in a serving of Jiff Creamy Peanut Butter are due to protein



What is Fat?

    -Fat is another macronutrient, essential for energy,               absorbing certain vitamins, and supporting cell growth.       It's also important for providing satiety and flavor in         foods.




How much fat is contributing to the % DV?

    -Jiff Creamy Peanut Butter contributes approximately 24.62% of the Daily Value for fat per serving.


What ingredients are contributing the fat?

    -The combination of roasted peanuts and added vegetable oils primarily contributes to the fat content in     Jiff Creamy Peanut Butter.


What types of Fats does it contain?

    -Jiff Creamy Peanut Butter may contain a small amount of saturated fats due to the added fully hydrogenated vegetable oils (rapeseed and soybean). However, the majority of the fat content in peanut butter comes from monounsaturated and polyunsaturated fats, which are beneficial for health when consumed in moderation.


How many calories are due to fat?

    -Calories from fat = ( Fat per serving ) × ( Calories per gram of fat ) = 16g × 9 cal/g = 144                     calories. So, in a serving of Jiff Creamy Peanut Butter, approximately 144 calories are due to fat.\



Food Or Additives?

Food:

Roasted Peanuts

Sugar

Molasses


Additives:

Fully Hydrogenated Vegetable Oils (rapeseed and Soybean):

   - Texture and Creaminess: Fully hydrogenated vegetable oils can contribute to the creamy texture of the product, enhancing its mouthfeel.

   - Stability: Fully hydrogenated oils are solid at room temperature, which can help stabilize the product and prevent it from separating.

   - Extended Shelf Life:Hydrogenation can increase the shelf life of oils by making them less prone to oxidation, which can help prolong the freshness of the product.

   - Replacing Trans Fats: Fully hydrogenated oils may be used as a substitute for partially hydrogenated oils, which are high in trans fats. By using fully hydrogenated oils, the product can avoid the trans fat content while still achieving the desired texture and stability.


Mono and Diglycerides: (emulsifiers) 

   - Texture Enhancement: Emulsifiers help blend together ingredients that would otherwise separate, contributing to a smooth and uniform texture.

   - Increased Shelf Life: By stabilizing the emulsion of fats and water in the product, mono and diglycerides can help prolong shelf life by preventing oil separation and maintaining freshness.

 - Improved Mixing Properties: Emulsifiers can aid in the mixing and blending of ingredients during production, ensuring a consistent product.


Salt:

Although a natural ingredient, it's considered an additive when it's added in a processed form. Salt likely serves to enhance the flavor of the peanuts and balance the sweetness from the sugar and molasses. Additionally, it may act as a preservative to extend the shelf life of the product by inhibiting microbial growth.


Vitamins and Minerals:

2 vitamins or minerals present are Vitamin B3 & Vitamin E

Niacin (Vitamin B3): The product contains 30% of the Daily Value for niacin per serving. 

  • Niacin is essential for the proper functioning of the body, primarily playing a crucial role in energy metabolism by helping convert food into energy. It also supports the health of the skin, nerves, and digestive system. When you don't get enough niacin, it can lead to a condition called pellagra, characterized by symptoms such as dermatitis (skin inflammation), diarrhea, dementia, and potentially death if left untreated. Pellagra was historically common in populations whose diets were heavily reliant on corn-based foods lacking niacin or its precursor, tryptophan (https://pubchem.ncbi.nlm.nih.gov/compound/938)

Vitamin E: The product contains 10% of the Daily Value for vitamin E per serving. Vitamin E is a fat-soluble antioxidant that helps protect cells from damage caused by free radicals. It also plays a role in immune function and skin health.

  • Vitamin E is a powerful antioxidant that helps protect cells from damage caused by free radicals, which are harmful molecules that can contribute to chronic diseases and aging. It also supports immune function and promotes skin health. When there's a deficiency of vitamin E, it can lead to neurological problems due to nerve damage, muscle weakness, impaired immune function, and vision problems. However, vitamin E deficiency is rare and usually only occurs in individuals with specific medical conditions that impair fat absorption or metabolism.

Carbohydrates

Sugars:

   - Total Sugars: 3g

   - Added Sugars: 2g

The likely types of sugars present are sucrose (from the added sugar), and natural sugars such as glucose and fructose from the peanuts and possibly molasses.


Fiber:

   - Dietary Fiber: 2g

There are a combination of soluble and insoluble fiber. Peanuts contain both types of fiber. Molasses may contribute a small amount of soluble fiber.


Starch:

   - Total Carbohydrates: 8g

   - Sugars: 3g

   - Fiber: 2g

Starch = Total Carbohydrates - Sugars - Fiber = 8g - 3g - 2g = 3g


Calories from Carbohydrates:**

   - Total Carbohydrates: 8g

   - Dietary Fiber: 2g

   - Calories per gram of carbohydrate: 4 calories


Calories from Carbohydrates = 6g x 4 = 24 calories per serving



Calories Per Serving

   - Fat: 16g x 9 calories/g = 144 calories

   - Protein: 7g x 4 calories/g = 28 calories

   - Carbohydrates: 24 calories

M4 Lab 7  T's Special Oatmeal Ingredients: Chocolate Milk Oats Peanut butter Frozen blueberries Steps: Boil 1 cup of chocolate milk Throw in half cup of oats once milk comes to top boil Continue to lower heat and stir oats till the liquid soaks into the oats Once the oats come to a preferred texture, put in bowl I mixed in a spoon full of organic peanut butter and then just topped it with frozen blueberries  Taste test: For some reason it tasted very cookie-like with its own richness. It was mushy which is how I like to have my oatmeal. I liked how it looked like coco pebbles soaked and thickened in milk. I was able to taste the burnt parts where the oats were a little burnt and overcooked as well as the burn dairy part of it. But it wasn't anything too noticeable. When oats are boiled into chocolate milk the starch in oats absorbs water from the chocolate milk and undergoes gelatinization when heated. This process thickens the mixture, resulting in a creamier texture. The fib...
