Coconut oil (Superfood)


Posted by 22yuanl | Posted in Science | Posted on April 21, 2017

Superfoods are foods which make us healthy, live longer, and have a lot of vitamins. Most superfoods are usually natural ingredients and vegetables/fruits, although there are exceptions. The most well-known superfood is blueberries. Blueberries have a lot of important nutrients and vitamins. However, many of the superfoods are fake. They advertise themselves as if they are very healthy and have a lot of vitamins, but this is not always true. Most could be easily replaced by common fruits such as bananas and oranges. This means that you would be wasting money on the superfood when you can be buying healthier foods for a cheaper price. Using the word “super” may be misleading to people who are buying it because it makes the food sound good without people considering whether it is real or fake. This means that people wouldn’t get the appropriate superfood that helps them. Buying fake superfoods could be dangerous because if people buy the fake superfood to cure diseases, it won’t help them but instead wasting money on it.

The superfood I chose is coconut oil. These are some of the effects of coconut oil:
1. Coconut oil has a special type of fat called medium chain triglycerides. This type of fat is healthier for your body than the regular type of fat found in foods like butter. Medium chain triglycerides can also help you lose weight.
2. When applied to the skin, coconut oil has a moisturizing effect.
3. It cures a lot of diseases such as Alzheimer’s disease and breast cancer.
4. Coconut oil also helps with hair care. Coconut oil can be found in conditioners and makes hair shiny.

I compared coconut oil to olive oil because I thought they were similar types of oil. The fat content and amount of Kcal were very similar. Olive oil has 100g of fat per 100g while coconut oil has 99.06g of fat per 100g. Olive oil has 884 kcal per 100g, and coconut oil has 892kcal per 100g. These are very similar. These two foods also have 2 types of vitamin- vitamin K and vitamin E. Vitamin K helps with building strong bones and Vitamin E helps protect cells from damage. Olive oil has 60.2g per 100g of vitamin K while coconut oil has only 0.6g per 100g of Vitamin K. Olive oil has 14.35g per 100g of Vitamin E while coconut oil has 0.11g per 100g. The Olive oil definitely beat the coconut oil when it came to vitamins but the coconut oil has more uses. I think it’s very strange that the olive oil has more vitamins than coconut oil but is not considered a superfood. I still think that coconut oil is better because it helps with dieting, has a moisturizing effect, cures diseases and helps hair care.

In Science, We’re learning about elements in a technology. We use technology every single day for work and for fun. We had to choose which technology we want to focus on and choose one. I chose iPhone from apple, iPhone is probably the most popular phone in the world.  Apple sells three models, 16GB, 32GB, and 64GB. Prices of the newest iPhone are: iPhone 7: $649 (32 GB), $749 (128 GB), $849 (256 GB) iPhone 7 Plus: $769, $869, $969. The iPhone 5 has Platinum, Aluminum, copper, Gold, and silver, these are the most important elements in the iPhone 5. Most of the cell phones use Gold which is used to coat wiring and is the most expensive metal inside a cell phone laptop, Tantalum which stores electricity, Tin is used a solder on a circuit board, and tungsten which makes sure the phone vibrates.

What each part is made of in iPhone 6s

Outside of the iPhone 6s

  • The case uses aerospace-grade Aluminum with and outside layer for extra protection. The paint for the iPhone is only 5 micrometers thick. That’s thinner than regular paint!
  • The camera is made of sapphire glass, the lens rates a 9 on a Mohs Hardness Scale, making it almost as hard as a diamond. So if you’re wondering how your screen breaks but your camera didn’t, that’s why.
  • The iPhone’s screen is much much more complex than it may look like to you. The aluminosilicate glass has ions for strength. The 2nd camera has Aluminum. The screen is made of silicon, Potassium, Indium, Tin and rare earth metals. Some of the rare earth metals are used to produce colors on the screen. A layer of tin oxide is used to make the touch screen possible.

Inside the iPhone 6s

  • The Battery is made of cobalt, Graphite, Lithium, and Aluminum.
  • The music or anything you hear on your iPhone is because of high-powered neodymium magnets. It’s made from neodymium, iron, and sometimes has other rare earth elements. The same magnets also make the phone vibrate. Nickel, Neodymium, Praseodymium, Boron, Dysprosium, and iron are all the elements in sound and vibration for the iPhone.
  • The electronics in the iPhone is the most complicated. The processor chip is made of Phosphorus, Antimony, Arsenic, Boron, Indium, Gallium, and silicon being the main one because it’s mainly made from silicon.  Micro and electrical, Copper, gold, silver, and tungsten is used for electrical connections on the phone.  The silver is the most useful metal for this.
  • Micro-capacitors makes sure the electricity go normally. apple managed to make the Tantalum conflict free in 2014.
  • The soldering in electronics is made of copper, tin, silver.


Where do the materials come from?

The smartphone is made from mined materials which mostly comes from the congo. Most smartphones use the same materials. Gold comes from Peru, Copper comes from chile, silver comes from Australia, Platinum comes from South Africa. People from Congo are forced to mine minerals for phones and laptops. They don’t get any salary. The armed groups force them to mine in Eastern Congo. Then the armed groups started controlling Uganda and Rwanda and other neighbors. The country makes millions selling these materials but the money is used to buy guns and grenades. The materials then ship to Thailand, Malaysia, China, and India to be refined. The minerals get mixed with other minerals.

What could we do?

Like I said before, Tungsten in Apple is already a conflict-free product. We could demand conflict-free products by getting in touch with cell phone manufactures and laptop companies. If Apple can make Tungsten conflict free, they can make other elements conflict free too.
