UNIT 5 "HEALTHY FOOD"

What do you think about healthy food?

I think about the healthy food, is beneficial to health, and provides all the essential nutrients and energy that each person needs to stay healthy.

Usually "healthy" food are that ones you can find in an orchard, they are natural foods, organic foods, whole foods, and sometimes vegetarian or dietary supplements. Such products are sold in health food stores or in the health/organic sections of supermarkets.

A well-fed person has more opportunities:

     • To develop fully

     • Healthy Living

     • Learn and work better

     • Protect yourself from diseases

The varied diet ensures the incorporation and use of all the nutrients, that we need to grow and healthy living.

Healthy eating, not only improves the quality of life at all ages, has been shown to prevent the development of diseases such as:

-       Obesity

-       Diabetes

-       Cardiovascular and cerebrovascular diseases

-       Hypertension

-       Dyslipidemia

-       Osteoporosis

-       Some cancers

-       Anemia

-       Infections

Also, I have to tell you about four types of foods you should not miss in a healthy diet

-       fruits

The fruit is an important source of vitamins and minerals. It is a food that contains fat, and helps us maintain proper cell function. Therefore eat daily is necessary, prevents premature aging. It is also true that the fruit contains carbohydrates, so we cannot abuse of them, and we must consume them at morning, because that’s the moment when the metabolism works faster and is easier to consume excess glucose.

-       vegetables

Like fruit contain high amounts of vitamins and minerals, making this food group an essential daily for healthy diet. Vegetables also don´t provide us fat and help us to maintain good function of the body. This type of food can be consumed at any time, just need to know how to prepare to avoid adding fat. So eat steamed, roasted or raw is the best choice.

-       fish

Fish is one of the best protein sources at our disposal. Fish offers very high biological proteins and easily assimilated by the body value. This nutrient is needed to maintain muscles and tissues in perfect condition. But not only the fish gives us this nutrient, but we must emphasize its mineral content and low calories.

-       cereals

Cereals are the basic diet of all human, as that provide carbohydrates. All cereals we also provide B vitamins, necessary for the proper functioning of the body. A point to consider is to choose the type of cereal that we will eat , and it must be integral for better use of our organism and not take spikes of glucose

UNIT 3 "HUMAN WONDERS"

What do you know about “Human Wonders”?

 

 

Regarding to the question, I read an interesting article focusing on the engineering wonders of the world.

With the passing of the years people have different needs and problems, so the engineers had to create, design and make amazing things which satisfy human needs somehow or other.

 

Below I’m going to resume about 10 engineering wonders of the world; they are made to solve many problems and to make our lives easier.

1. - Akashi Kaikyō Bridge (Japan)

This bridge is the world’s largest cable bridge and there are no pillars for the supports. It has the longest central span of any suspension bridge in the world, at 3911 meters

2. - Millau Viaduct (France)

It is the tallest bridge in the world with one mast’s summit at 3430 meters (1,125 ft) above the base of the structure.

3. - USS George H.W. Bush (CVN-77) (USA)

USS George H. W. Bush stretches 1,092 feet and displaces over 100,000 tons, making her one of the world’s largest warships (though it is slightly shorter than USS Enterprise) but equipped with latest technology which was not used before

4. - North European Gas Pipeline

(Russia – Germany) 

North European Gas Pipeline is an offshore natural gas pipeline from Vyborg in Russia to Greifswald in Germany. It is the longest sub-sea pipeline in the world, and was inaugurated on 8 October 2012. At 1,222 kilometers (759 mi) length.

5. - Beijing National Stadium (China)

World’s largest steel structure, Beijing National Stadium also known as the Bird’s Nest is a stadium in Beijing.

6. - Bailong Elevator (China)

The highest and heaviest outdoor elevator in the world, The Bailong Elevator is a glass elevator built onto the side of a huge cliff in the Wulingyuan area of Zhangjiajie, that is 1,070 feet (330 m) high.

7. - Palm Islands (United Arab Emirates)

Here is another great example of the Modern Engineering’s success, these islands are the world’s biggest artificial islands in Dubai, There are 1500 villas in it and all are on the artificial beaches. The islands are the Palm Jumeirah, the Palm Jebel Ali and the Palm Deira.

8. - Eurotunnel (England-France)

It’s the second longest underwater tunnel in the world; this is an amazing sample of the Modern Engineering, this tunnel start from England and End in France. Interest thing is that this is in water. The length of this tunnel is 31 miles and 23 of which is in the sea.

9. - Three Gorges Dam (China)

The Three Gorges Dam is the world’s largest power station in terms of installed capacity (22,500 MW). Not only does it produce electricity for the area, provides flood storage space. Construction of the dam began in 1994; it opened for commercial operation in 2008.

10. - Pan-STARRS (USA)

Pan-STARRS is an acronym for Panoramic Survey Telescope & Rapid Response System. It is the most advanced telescope in the world. It is an innovative design for a wide-field imaging facility developed at the University of Hawaii’s Institute for Astronomy. A key objective of Pan-STARRS is to identify and characterize Earth-approaching objects, both asteroids & comets that might create a danger to our planet. It’s also ideal for research in several other astronomical areas.
