There are three macronutrients in food: carbohydrates, fat and protein, ‘macro’ in the sense that they comprise almost all of the weight and calories of food. Vitamins and minerals are the micronutrients.

Protein, ever since its discovery in 1839, has been considered by many people to be an exceptionally important nutrient, often assuming that the more we consume the better. Its name comes from the Greek word, proteios, meaning ‘of prime importance’—an auspicious and almost mystical beginning for the future of this nutrient! Add to this importance the long standing impression by most people that protein is exclusive to animal source foods.

We now know, however, that this importance is exaggerated, to mythical proportions. For a starter, protein is not exclusive to animal-based foods. In the late 1800s protein was also found to be present in plant foods. Yet the myth of its being tightly or even exclusively linked to animal-based foods still lingers. Simply ask a non-meat eating vegan how many times they are asked, “But where do I get my protein?”

This bias implying that meat is the sole source of protein was encouraged over these many decades by ‘science’. Research findings, for example, were showing that animal-based proteins are utilized by the body more efficiently. This efficiency of utilization referred to increased body growth rate among other effects, with greater efficiency being described as greater ‘biological value’ or higher quality. But it was only animal-based proteins that have high quality.

Because most people obviously like high quality, animal-based protein became the protein of choice. In effect, this history evolved through the prism of linguistics to give a profound self-perpetuating paradigm.

The problem with this proposition is that high quality does not necessarily mean better health. Increasing body growth may be useful for…...

...Introduction: Insulin resistance is associated with type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), both independently and in association with the metabolic syndrome. Impaired insulin sensitivity has been documented in those known to be at risk for diabetes, such as normoglycemic first-degree relatives of people of T2DM, and women with history of gestational diabetes. Although present in most people who developed T2DM, insulin resistance is generally present for many years before changes in blood glucose concentrations are evident. Despite possible influences from genetic and perinatal factors, diet and physical activity are likely to have greater and overriding influence in generation of the metabolic syndrome and T2DM. Dietary intakes of vegetable fat, polyunsaturated fatty acid, dietary fiber (particularly cereal fiber), magnesium, and caffeine are significantly inversely correlated and intakes of trans fatty acid and heme-iron, glycemic index, and glycemic load are significantly positively correlated with the incidence of type 2 diabetes (Murakami K et al J Nutr Sci Vitaminol (Tokyo) 2005; 51:292-310). Studies have shown a significantly decreased risk for T2DM with the higher consumption of grain (particularly whole grain), and significantly increased risk with processed meat consumption (J Nutr Sci Vitaminol (Tokyo) 2005; 51:292-310). Increased obesity is associated with insulin resistance. Other important factors contributing to insulin resistance......

...Natural Weight Loss and Diet Pills Taking diet pills could bring immediate results; however, eating healthy foods and exercising regularly is the best way to lose weight. The body can maintain its ideal weight when it is focused by a healthy lifestyle. A healthy lifestyle consists of eating nutritional foods as well as exercising regularly. Developing a new style of eating will show that food preferences will slowly change when high sugar and high fat snacks are cut out; cravings will go away in time. The body needs healthy food to function properly. Choosing foods from the four main food groups can be a guide for creating balanced and nutritional meals. By choosing to eat healthy, there is more room for enjoyment. Instead of the typical three meals a day (breakfast, lunch, and dinner), a person can eat four to five small proportional meals each day. The weight gain and loss will be controlled as long as the person does their homework. Counting the calorie food intake is necessary to be sure that a person consumes 1,200 to 2,000 calories a day. Drinking six to eight glasses of water a day and a large glass of water with meals as well as after a meal can help control appetites and metabolize fat. The day should begin with a healthy breakfast. This consists of foods such as eggs, which contain protein, orange juice that has vitamin C, and one slice of toast to give the body fiber. To help with hunger building up, try eating about two snacks between meals. However, it is......

Diet Comparison

...That is the level the dieter needs to ingest to maintain the desired weight.4 The Atkins Program has many pros to it. There are no meetings to attend. There are no prepackaged meals to buy. If the induction period is strictly followed, a dieter can potentially lose a significant amount of weight during that period. Exercise is stressed in the program to maintain a healthy lifestyle. The Atkins Program can be modified to accommodate a vegan, vegetarian or gluten free dietary preference. There is on line support including forums, carb counters and menus. There are considerable cons to the Atkins Program. Dieters with kidney problems should not enter into a diet with high protein intake. The decrease in carbs can limit the variety of food available to the dieter, especially in the induction phase. While on the Atkins Diet, the dieter may have to supplement secondary to missing certain nutrients, including fiber. Based on these cons, another program may be better suited for an individual.5 Weight Watcher’s is a meeting based diet plan where all foods are allowed. The basic theory is that a dieter can eat all foods within a set “points” limit. A dieter’s point value is based on height, weight, age and sex. Once this point number is determined, a dieter can chose from any food group and will be able to slowly lose weight by staying at our below that point value. Each food item is assigned a value of points and must be tracked. Extra points each day are awarded......

...Many diets have been developed to help people lose weight. However, many of these diets were developed without the input of dieticians or doctors, which makes them potentially dangerous. Understanding the pros and cons of a diet are vital to increasing the chances of success. One of the most popular diets in the last ten years is known as the South Beach diet, developed by Dr. Arthur Agatston. Unlike many competing diets, a famous cardiologist developed the South Beach diet. His medical training helped him develop a diet that follows medical guidelines and is not extremely dangerous if followed accurately. The diet requires the person to eat high-fiber, low-glycemic carbohydrates, unsaturated fats, and lean protein. His method categorizes carbohydrates and fats as good or bad, based on how much the food will affect weight. Unlike other diets, it does not restrict calorie intake. However, it does include an exercise program, which works to burn off existing calories. While many people promote the South Beach diet, it is not considered to be side effect free. The first stage of the diet aims for rapid weight loss by cutting water weight. The change in weight due to the loss of water can throw off the electrolyte balance and severely dehydrate the person. Other critics believe that the lack of dietary fiber, which is known to aid in weight loss, can have a negative affect on the body. Also, certain doctors believe that the glycemic index, on which the diet is based, is not...

Vegetarian Diet

...5 types of vegetarian The vegan This is the most limiting type of vegetarian diet. Vegans not only eliminate all animal-based foods but avoid dairy products of all types as well as eggs. While generally considered to be a healthy diet in terms of preventing disease, it takes planning to get enough protein, iron, and calcium on a vegan diet, although it’s not impossible. Many people start out with less restrictive form of vegetarianism and gradually progress to a vegan diet over time.  Lacto-vegetarianism People who adopt a lacto-vegetarian diet abstain from all meat products, including eggs, but continue to eat dairy products. The advantage to this form of vegetarianism is you’re less likely to develop a calcium deficiency due to the inclusion of calcium rich milk products. Lacto-ovo vegetarianism Lacto-ovo vegetarians avoid all meat but allow themselves to eat both dairy products and eggs. The inclusion of eggs and milk makes it easier to maintain calcium and protein levels and is, in general, an easier form of vegetarianism to adapt to, particularly if you eat out a great deal. Have you ever stopped to consider how many baked goods contain eggs and dairy products? Pescatarians One of the least restrictive forms of vegetarianism is the pescatarian lifestyle where you avoid all meat products with the exception of fish. Many people don’t consider pescatarians to be true vegetarians since they allow themselves to eat seafood. They also consume dairy products......

Vegan Pregnancy

...Drexel University Plant Based Pregnancy Planning your diet is a complex, time consuming task. It is shaped by culture, marketing, politics, economics, necessity, and desire. Diet is one of the biggest and most important factors in our overall health. Our diets are linked to an increase in obesity, diabetes, hypotension, cancer, and cardiovascular disease. Obesity, which represents a caloric intake well over what is needed, is s major concern. Particularly in western culture, where a diet that emphasizes high fat, caloric dense food has been implicated as a connection to several negative health outcomes. It is accepted by heath care professionals, and pregnant women that nutritional status during pregnancy plays an important role in a healthy pregnancy. Women with poor nutrition can experience complications with labor, as well as compromised fetal growth, resulting in low birth weight. Pregnant women who gain more or less weight than the recommended amount can result in complications for both mother and baby. The incidence increases at the extremes of weight gain. What is an expected mother to be to do? An increased number are looking into dietary alternatives. One alternative, that is growing in popularity, is a vegan diet. What is a vegan diet? A vegan, or plant based, diet is a form of vegetarianism. It differs in that individuals following this diet consume zero animal products. This means that vegans do not eat any meat, diary, eggs, honey, or any other......

The American Diet

...Maria Arriola Allegra Hyde English 101 16 November 2014 The American Diet Getting a fat whopper from McDonalds, large fries and a coke is seen as an average meal for Americans. There are many diets out there like the Paleo diet, and the Atkins diet and the standard american diet which all revolve around the consumption of meat, dairy and fats. The very thought of an American eating a vegan plant based diet is seen as extreme and often questioned. Eating no meat, or products derived from animals automatically makes one an extreme animal rights activist that solely lives on salads. Nutrition is often overlooked by doctors but it may be the underlying issue of a spectrum of problems. Thomas Edison once stated “The doctor of the future will no longer treat the human frame with drugs, but will rather cure and prevent disease with nutrition.” Many do not realize the great importance of nutrition and its correlation to health. What enters the body may greatly affect the overall individual physically and mentally. Americans have become unhealthier by the years due to the vast number of processed products sold in our grocery stores today. Many do not take notice of their daily consumption of food while others obsess over the very thought of their next meal. There is a great epidemic in America where more people die from the effects of overeating rather than starvation. Many resort to drugs, and surgeries as a quick fix in hopes of improving their health which leaves many......

Vegan Diet for Elderly

...Title: Semi-Vegetarian Diets for Elderly Name: Demasuay, Klyne Lauriz S. Date: October 28, 2015 Section: 4N1 What is a semi-vegetarian diet? Semi-Vegetarian is a term recently coined to describe those who eat a mostly vegetarian diet, but occasionally eat meat. Many people who call themselves "semi-vegetarian" have given up red meat for health reasons while others, for environmental reasons, only eat free-range or organic animals and animal products. What is my stand on semi-vegetarian diet for the elderly? As a future nutritionist-dietitian, I will fully support the choice of the elderlies to engage themselves in a semi-vegetarian diet. As mentioned above, they occasionally eat meats which include eggs, chicken and fish. Also this kind of vegetarianism eats tofu, beans, lentils, peas, nuts and seeds which provides for the additional protein and calcium needs of the person. The elderly group is prone to diseases like diabetes, hypertension and other chronic diseases. This diet can help them avoid the said illnesses since this diet is low from fat and sugar content. Even though the elderly have high tendency to undernutrition, it is still recommended to have a minimum 0.8g of protein per kilogram body weight since their absorption of nutrients is incomplete or lowers and avoid the disruption of the aging kidneys. The semi-vegetarian diet is mostly of complex carbohydrates since there is an increase in the intake of vegetables, this aspects could also help...

Vegan Diets

...Analyzing Arguments: Is Vegan/Vegetarianism Diets Healthy? Eating is a necessary task humans undertake every day to survive and thrive. Food has become a huge part of society’s everyday culture and an essential aspect in our economy. As humans, we are capable of choosing the types of food we put in our bodies and these choices define in part what we look like and what we stand for. People choose whether they would like to be carnivores, vegetarians, vegans, or a combination. Author Ben Kim, a chiropractor and acupuncturist in Barrie, Ontario, Canada, states his thoughts on these choices in his article “A Strict Vegetarian Diet Is Unhealthy for Most People.” His article was written in 2010 to discourage people from adopting 100% vegan diets because in his opinion these diets are dangerous to the long term health of humans. Kim addresses his article to people who have adopted or are thinking of adopting 100% vegan lifestyles. He is trying to convince these groups that it is unhealthy long-term to limit yourself to a 100% plant-based diet. The main ideas Kim states in order to dissuade his audience from adopting vegan diets are that 100% vegan diets lead long term to the development of nutritional deficiencies and significant health problems, that the morality of vegan lifestyles are questionable, and that the organizations that promote vegan lifestyles have ulterior motives. While Kim makes a weak argument against 100% vegan diets, his assertion that diets with a majority of......

Controversial Side of Vegan

...The Controversial Side of Going Vegan "We spend far more, per capita, on health care than any other society in the world, and yet two-thirds of Americans are overweight, and over 15 million Americans have diabetes, a number that has been rising rapidly. We fall prey to heart disease as often as we did thirty years ago, and the War on Cancer, launched in the 1970s, has been a miserable failure. Half of Americans have a health problem that requires taking a prescription drug every week, and over 100 million Americans have high cholesterol"(Campbell 3). With statistics like that being completely preventable with a vegetable based diet, there are still many people who believe the vegan way of life unhealthy and unsustainable. The prevailing causes behind society’s misunderstanding of this controversial diet are protein and fat soluble nutrients. Protein and fat soluble nutrients are a staple in any healthy diet, and it has been long believed that a vegan lifestyle does not support this. We also live in a culture known for the Standard American Diet (S.A.D). The standard American Diet is known for being high in animal fats, and low on essential plant based nutrients. (Campbell 196) Surprisingly enough this more uniformly accepted as a complete diet by the masses. In 1992 the USDA released a food pyramid as an answer to the growing obesity, and poor health reviews plaguing the nation. “The Food Guide Pyramids were developed by using nutrient profiles......

Raw Vegan

...annually. I was the canary in the coal mine; the first to pass out from carbon monoxide poisoning in high school auto shop, and I remember losing conciousness from heat exhaustion numerous times during my childhood. I was brought up on a typical southern diet consisting of overcooked, oversalted high-fat foods, obviously not a healthy situation. I continued the tradition after leaving home until the age of thirty. I did not connect my diet with my health problems when I was young. Once I realized the connection, I became impassioned with the desire to educate myself in dietary nutrition, ultimately completing a Bachelors degree in nutrition. Possibly the goal that has taken the most perseverance and determination to accomplish in my life is going from an extremely poor diet to what is probably the most healthy diet imaginable, a 100% raw vegan diet. My wife was the catalyst for my change to a healthier diet over the years. She had been raised in a household with much better awareness of healthy eating habits, and she began my dietary evolution by gradually eliminating meat from my meals. The major milestones of my dietary journey included becoming vegetarian, dairy-free, sugar-free, re-introducing raw dairy, and then finally raw vegan. I have made it a habit to read ingredient labels and to avoid all toxic substances. I only purchase organically grown produce. There were temptations and peer pressure along the way.
