dangers of low blood pressure – The Sugar
It comes as no surprise that the sugar is found in processed foods like candy, baked goods, canned foods, and frozen meals in the form of high-fructose corn syrup, but it is also hidden in less obvious foods like peanut butter, egg products, and soups. Many fruits and vegetables contain high levels of it naturally. Dr. Johnson shows how to cut way back on the sweetener by making effective substitutions. The daily meal plans included here contain no more than 25 grams of fructose, one-quarter of the amount the average American now ingests.
Rather than the low-carb approach of so many recent diets, Dr. Johnson recommends a much easier to enjoy and stick to formula: 50% carbs, 25% fat, and 25% protein. The immediate benefit of this diet is to help anyone shed excess weight. The additional benefits are even more impressive—reduced risk for such serious health problems as high blood pressure, elevated blood fats, and insulin resistance, conditions directly linked to heart disease, diabetes, kidney disease, and stroke.
Vanuatu Islands
Vanuatu was first inhabited by Melanesian people. Europeans began to settle in the area in the late 18th century. In the 1880s France and the United Kingdom claimed parts of the country, and in 1906 they agreed on a framework for jointly managing the archipelago as the New Hebrides through a British-French Condominium. An independence movement arose in the 1970s, and the Republic of Vanuatu was created in 1980.
History
The prehistory of Vanuatu is obscure; archaeological evidence supports the commonly held theory that peoples speaking Austronesian languages first came to the islands some 4,000 years ago. Pottery fragments have been found dating back to 1300–1100 B.C.E.
The first island in the Vanuatu group discovered by Europeans was Espiritu Santo, when in 1606 the Portuguese explorer Pedro Fernandes de Queirós working for the Spanish crown, spied what he thought was a southern continent. Europeans did not return until 1768, when Louis Antoine de Bougainville rediscovered the islands. In 1774, Captain Cook named the islands the New Hebrides, a name that lasted until independence.
In 1825, trader Peter Dillon’s discovery of sandalwood on the island of Erromango began a rush of immigrants that ended in 1830 after a clash between immigrant Polynesian workers and indigenous Melanesians. During the 1860s, planters in Australia, Fiji, New Caledonia, and the Samoa Islands, in need of laborers, encouraged a long-term indentured labor trade called "blackbirding". At the height of the labor trade, more than one-half the adult male population of several of the Islands worked abroad. Fragmentary evidence indicates that the current population of Vanuatu is greatly reduced compared to pre-contact times.
It was in the 19th century that both Catholic and Protestant missionaries arrived on the islands. Settlers also came, looking for land on which to establish cotton plantations. When international cotton prices collapsed, planters switched to coffee, cocoa, bananas, and, most successfully, coconuts. Initially, British subjects from Australia made up the majority, but the establishment of the Caledonian Company of the New Hebrides in 1882 soon tipped the balance in favor of French subjects. By the turn of the century, the French outnumbered the British two to one.
The jumbling of French and British interests in the islands brought petitions for one or another of the two powers to annex the territory. In 1906, however, France and the United Kingdom agreed to administer the islands jointly. Called the British-French Condominium, it was a unique form of government, with separate governmental systems that came together only in a joint court. Melanesians were barred from acquiring the citizenship of either power.
Challenges to this form of government began in the early 1940s. The arrival of Americans during World War II, with their informal demeanor and relative wealth, was instrumental in the rise of nationalism in the islands. The belief in a mythical messianic figure named John Frum was the basis for an indigenous cargo cult (a movement attempting to obtain industrial goods through magic) promising Melanesian deliverance. Today, John Frum is both a religion and a political party with a member in Parliament.
The first political party was established in the early 1970s and originally was called the New Hebrides National Party. One of the founders was Father Walter Lini, who later became Prime Minister. Renamed the Vanua’aku Pati in 1974, the party pushed for independence; in 1980, amidst the brief Coconut War, the Republic of Vanuatu was created.
During the 1990s Vanuatu experienced political instability which eventually resulted in a more decentralized government. The Vanuatu Mobile Force, a paramilitary group, attempted a coup in 1996 because of a pay dispute. There were allegations of corruption in the government of Maxime Carlot Korman. New elections have been called for several times since 1997, most recently in 2004.
Geography
Vanuatu is an island archipelago consisting of approximately 82 relatively small, geologically newer islands of volcanic origin (65 of them inhabited), with about 800 miles (1,300 km) north to south distance between the outermost islands. Two of these islands (Matthew and Hunter) are also claimed by the French overseas department of New Caledonia. Fourteen of Vanuatu’s islands have surface areas of more than 100 square kilometres (39 sq mi). From largest to smallest, these are Espiritu Santo, Malakula, Efate, Erromango, Ambrym, Tanna, Pentecost, Epi, Ambae or Aoba, Vanua Lava, Gaua, Maewo, Malo, and Anatom or Aneityum. The nation’s largest towns are the capital Port Vila, situated on Efate, and Luganville

Dolphins have extremely sensitive skin, which has a rubbery feel. Their circulatory system is very good for preserving heat, with blood vessels in their dorsal fin, flippers and tail re-warming cool blood to spread around the body. Dolphins also have fantastic eyesight, enabling them to see both in and out of the water. However, they can only see infront of them and below them, and so have to swim upside down sometimes to catch fish.

The average size of Bottlenose Dolphins is between 2 – 4 metres long, weighing between 90 – 650 kilograms. However, they vary in looks according to where they live and spend their lives. Dolphins eat plenty of food daily, totaling about 5% of their body weight. They catch fish, octopus and squid with their sharp teeth, although swallow the food whole and digest it in their stomachs.
Dolphins can stay under the water for about 15 minutes, and can swim to depths of over 100 metres due to their collapsible ribs, which vary according to the water pressure. They can also jump about 6 metres out of the water, and love surfing on waves.
Dolphins have a wide range of ways of communicating, much like humans. Ways in which they communicate with each other include body posture, bubble blowing, chemical releases, language, sound, touch, and splashing on the waters surface.

Dolphins can be recognised by their unique ‘Signature Whistle’, which is an extremely high-pitched sound. This sound comes from their blowhole on the top of their heads. They also send out clicking sounds, which bounce back to their forehead to identify the size and distance of objects around them.

Due to the constant danger of predators Dolphins don’t every sleep, they merely nap for about 30 minutes with half their brain alert.

Dolphins become sexually active at around the age of 10 and generally live up until around 30 years old. Female Dolphins carry young for 12 months and give birth to live young. During the birth an ‘aunty’ dolphin will help, although many calves are soon taken by predators. When this happens the mothers mourn for their young, continually pushing them to the surface to breathe.
During the first two years of birth the calves will feed off of milk from the mother. Dolphins give birth every 2 – 4 years and once the calf is about 3 years old, it is ready to go off on its own.
Dolphins are in great threat from a wide variety of objects and actions within the water. Dolphins and other marine life often get caught up in fishing lines, and have difficulty with Stainless Steel hooks caught in their mouths. Rubbish and other waste products can also be swallowed by Dolphins, causing pain. They also often have difficulty getting out of the way of speed boats and jet skis.
