Becoming a pescetarian was one of the most important and life-changing decisions that I've ever made -- and I made it at age 14. I have not eaten meat since then except for fish, and I don't plan to for the rest of my life.

You may be wondering, "What is a pescetarian?" Pescetarianism, or pesco-vegetarianism, means being vegetarian while still including seafood in your diet. One still cuts out red meat, pork, poultry, etc. from his or her diet like a vegetarian, but does not cut out fish and other seafood.

One of the biggest meat-lovers I ever met, my loving boyfriend Mick Merivel, has even adopted the pescetarian diet. He has been a pescetarian now for the past three months and has been pleasantly surprised at how easy it is -- even though he had been eating meat regularly for the past 30 years. He says, "The switch to a pescetarianism diet was not hard for me at all, because the ability to continue to eat fish and seafood eliminated my desire for meat."

Many people ask me "How did you do that? I could never give up meat!" What a lot of people don't realize is that over time your body's unnatural craving for mammal and poultry meat disappears, and a healthy body will get sick from beef, pork or chicken if eaten again after a period of a pescetarian diet. This is because land-animal flesh is filled with toxins, uric acid and fecal bacteria.

And frankly, I believe that the human body should always reject these meats, but we are feeding it to our toddlers and convincing them -- as we have been convinced -- that it is natural and normal. But consider this, do natural carnivores have to cook their meat in order to not get sick and season it so it can taste good to them? Would a human baby kill and eat raw a live chicken out of instinct as for example a baby lion would? No.

Here's another thing to think about -- can we eat raw fish and seafood if it's healthy and clean and not get sick? Yes. Do we always have to season fish and seafood for it to taste good? No. Are there the same health risks from eating healthy, fresh fish as there are from eating land animals? No.

The only reason the human race started to eat land animals was back when cavemen had to survive in the wild, and berries and vegetables were scarce and killing mammals was their only way to survive. I would say we have definitely advanced since then -- everyone could survive on a vegan diet if they chose. That's all it is. It is making a decision to not only improve your health and extend your life, but contribute to saving our planet and natural resources -- and our animals -- who deserve to live a free and happy life as much as we do.

So I put together a list of the top five reasons why I believe you should go pescetarian. All I ask of you today is to try the 30 Day Challenge. All you do is take a pledge to cut out meat, excluding fish and seafood, from your diet for the next 30 days. With the increase of fresh fish and vegetables in your diet, I believe that you'll feel healthier, experience less headaches and sickness as well as increased energy levels. In the long-term, you may also improve your weight, the health of your brain and heart, hair and even your skin.

According to The New York Times, meat consumption in the United States has doubled in the last 50 years. And since then, haven't other problems increased? Cancer, heart disease, stroke, obesity: these have all increased drastically over the past 50 years. Any connection? These trends may go hand in hand.

1) Pescetarianism may drastically improve your health.

A pescetarian diet may not only reduce your risk for heart disease and other cardiovascular diseases, but stroke, osteoporosis, obesity, diabetes, arthritis, high blood pressure and some types of cancer. According to the Yale College Vegetarian Society, experts say that up to 80 percent of cancer cases are preventable through healthy diets that contain low amounts of fats and oils, and high amounts of fiber -- the model pescetarian diet.

Meat is often covered in pesticides and chemicals that are harmful, and after extended consumption, can be very dangerous, to humans. Every bite of a beef/pork hotdog contains seven cancer-causing pesticides. And here's a shocking fact, brought to light by David Steinman's "Living Healthy in a Toxic World": The primary source of nuclear radiation contamination in humans is from beef and dairy products.

Additionally, all of the iron you need comes from fish, many fruits and vegetables and whole grains. And all the protein you need comes from consuming a healthy percentage of legumes, whole grains, tofu, and many plant sources. Vegetarian diets supply more than adequate amounts of protein.

So now we know that we can get enough protein without eating any meat at all, where does including fish in our diets come in?

Fish is very low in saturated fat and contains very large quantities of polyunsaturated omega-3 fatty acids, which have been connected to possible treatments for an array of conditions including heart disease, depression and ADD. Omega-3s have also been shown to have potential risk-reducing effects when it comes to cancer, cardiovascular disease and diabetes. Another huge benefit of including fish in a vegetarian diet is the healthy amount of iron in fish and seafood. Pescetarians have a lower risk of developing iron deficiency anemia -- a common condition among vegans and vegetarians. Eating fish also combats D-3 deficiency, which is a common condition among many Americans.

2) Becoming a pescetarian benefits our planet.

The Vegetarian Resource Group reports that one pound of beef requires 2,500 gallons of water, whereas one pound of soy requires only 250 gallons of water and a pound of wheat requires only 25 gallons. If you want to help save our water, cutting meat from your diet one way that you get active.

Additionally, the deforestation caused by the need to create space to house livestock is tremendous. A Smithsonian Institution study shows that the demand for more grazing land means that every day, a land area equivalent to seven football fields is destroyed in the Amazon basin.

According to Earth Talk, "The Environmental Beef With Meat," for every hamburger that came from an animal raised on rainforest land, approximately 55 square feet of forest was destroyed. And it's not just the rainforest being destroyed. In the United States, more than 260 million acres of forest have been clear-cut for animal agriculture as of 2005.

The livestock in the Unites States also creates an unimaginable amount of waste and toxic emission -- as do the fertilizers used. Livestock raised for slaughter produce 130 times the excrement of the entire human population.

But most shocking of all is that the grains and corn that are wastefully fed to the mass amounts of livestock in the United States, could be instead be fed to the 60 million human beings who die of starvation every year all over the world.

3) I believe you aren't against animal cruelty unless you are some type of vegetarian.

Most people know somewhat of what is going on in slaughterhouses and cow, pig, chicken and turkey farms. They know that animals are bred for murder in these places so they can be killed and eaten for the pleasure of humans. But what some people may not know are the disgusting conditions and inhumane treatment of these innocent animals behind their closed doors. Animals are subjected to some pretty terrible living conditions, full of feces and flies, packed into crates so crowded that they can hardly move. Their natural habits are taken from them.

Chickens for example are kept in big warehouses in tiny wire cages as big as file cabinets -- packed with about 10 or more chickens. The chickens peck at each other, so their beaks are removed to prevent them from doing this. This is called de-beaking. This is done to each chicken with no painkillers. Their breasts are so heavy from injected growth hormones that they sometimes can't even stand, and their legs are often already broken. Many cages house chickens that have already died from disease.

The treatment of hogs and cows are just as terrible, often still alive and struggling as they are hung upside down and taken down a belt to have their throats slit or beheaded by an automatic machine. Many times the animal is not dead immediately, because their throat had only been nicked as they get hacked into pieces or boiled alive.

"If slaughterhouses had glass walls, everyone would be vegetarian."

- Paul McCartney

4) We aren't natural carnivores.

Natural carnivores have claws, pointed front teeth to tear raw flesh and no pores on the skin so they perspire through the tongue. Plant and fish eaters perspire through pores on the skin since they are searching for food during hot hours -- not hunting at sunrise, sunset or under cover of darkness as carnivores do. Carnivores also have a shorter intestinal tract than plant and fish eaters do so rapidly decaying carcasses in the stomach can pass out of the body quickly. Herbivores and omnivores have an intestinal tract that is several times their body length since a mostly plant-based diet doesn't include food that decays as quickly. The human intestinal tract is about 25 feet long. Doesn't that tell you something?

Fish on the other hand are digested much, much quicker than red meat. The omega-3 fatty acids that are in fish and seafood are necessary in the diet of a human being -- fish is the only true source of the omega-3 acids DHA and EPA. There is no supplement that needs to be taken when the flesh of land animals is cut out of the diet; it only improves your health to not eat this kind of meat.

I do acknowledge that it has been shown that fish farms can be inhumane -- even though fish are much less sentient and self-aware than land animals. However I still recommend you avoid fish that come from fish farms, and try to consume only wild fish that has been caught fresh. This way you get omega-3 acids in their purest and healthiest form, and also reduce your risk of consuming sick fish that may be packed with chemicals from fish farms. It's also similar to choosing to eat only free-range eggs -- like the hens who lay the eggs that get to run around free of a cage, these fish come from the sea or rivers in their natural habitats.

5) Many successful individuals choose vegetarian or pescetarian diets.

These people eat fish but no other type of meat, for fish is needed in the diet, and they understand this. Many people however who are pescetarian still refer to their diet as vegetarianism. This is very common and is not wrong to say -- pescetarian, also called pesco-vegetarian, is just a branch of vegetarianism. There are many types of vegetarians, and every one of them is making an effort to improve their health, contribute less to animal cruelty and help save our planet. Some types of vegetarians will accuse other types as being hypocrites, and attack their diet choices. For example, many vegans and vegetarians attack pescetarians, while they know that they themselves need to take fish oil capsules every day containing omega-3 acids to stay healthy, which they know only comes from fish. They ask, "How can you justify eating fish?" I ask, "How can you believe that it is not natural to eat something we as humans need to be healthy?"
