Why does the body need vitamins and minerals?
Vitamins are chemicals that the body needs to function well; minerals are metals and salts that the body also needs in tiny amounts to run properly. Both help the human body grow. Different foods, like vegetables, contain different amounts of vitamins and minerals, so it is important to have variety in your diet so you can get a good balance. When it comes to vitamins, each one works differently in your body. Vitamin D in milk helps your bones grow; vitamin A in carrots helps you see at night; vitamin C in oranges helps boost your immune system and helps your body heal if you get a wound; and the B vitamins in leafy green vegetables help your body make protein and energy. And although some vitamins like A (which helps your eyesight) and D are stored in your body (for several days or up to several months), others, like C and the B vitamins, quickly pass through your bloodstream. So it’s important to replace your vitamins every day.

    The Shoebill, Balaeniceps rex also known as Whalehead is a very large bird related to the storks. It derives its name from its massive shoe-shaped bill. The Shoebill is a very large bird, averaging 1.2 m (4 ft) tall, 5.6 kg (12.3 lbs) and 2.33 m (7.7 ft) across the wings. The adult is mainly grey, the juveniles are browner. It lives in tropical east Africa, in large swamps from Sudan to Zambia. The Shoebill was added rather recently to the ornithological lists; the species was only discovered in the 19th century when some skins were brought to Europe. It was not until years later that live specimens reached the scientific community. The bird was known to both ancient Egyptians and Arabs however. There exist Egyptian images depicting the Shoebill while the Arabs referred to the bird as abu markub, which means one with a shoe. Clearly, this refers to the striking bill.
