  • Review of the China Study
    FACT SHEET REVIEW OF THE CHINA STUDY By Team, General Conference Nutrition Council In 1905 Ellen White described the diet our Creator chose for us as a balanced plant-based diet including foods such as grains, fruit and vegetables, and nuts (1). Such a diet provides physical and mental vigor and endurance. She also recognized that such a diet may need to be adjusted according to the season, the climate, occupation, individual tolerance, and what foods are locally available (2). The General Conference Nutrition Council (GCNC) therefore recommends the consumption of a balanced vegetarian diet consisting of a rich variety of plant-based foods. Wherever possible those should be whole foods. Thousands of peer-reviewed research papers have been published over the last seven decades validating a balanced vegetarian eating plan. With so much support for our advocacy of vegetarian nutrition we have no need to fortify our well-founded position with popular anecdotal information or flawed science just because it agrees with what we believe. The methods used to arrive at a conclusion are very important as they determine the validity of the conclusion. We must demonstrate careful, transparent integrity at every turn in formulating a sound rationale to support our health message. It is with this in mind that we have carefully reviewed the book, The China Study (3). This book, published in 2004, was written by T. Colin Campbell, PhD, an emeritus professor of Nutritional Biochemistry at Cornell University and the author of over 300 research papers. In it Campbell describes his personal journey to a plants-only diet.

Pianalto: Ethics Beyond Sentience MATTHEW PIANALTO ETHICS BEYOND SENTIENCE To whom—or what—do we owe basic acknowledgment, respect, and consideration? To whom—or what—do we have those basic obligations? These are the questions I wish to probe in this essay. They are questions that can seem to require the drawing of lines, the identification of criteria that make some beings “morally considerable” while other beings do not warrant this kind of special moral attention. Such questions have received a great deal of attention from moral philosophers, and have generated many very different responses, ranging from views that regard human beings as sole possessors of this special property of moral considerability to views that attribute this feature to every corner of existence. Views of the latter sort will strike some as silly—overly romantic perhaps, and because of this, largely impractical. I am nevertheless often attracted to such views for the potential power they have to stimulate moral imagination. Such views ask us to move beyond human-centered ways of thinking about ethics and obligations, to see our responsibilities extending beyond the effects of our actions on our fellow humans.

  • Vegetarian Nutrition (PDF)
    Vegetarian Nutrition Many people choose to follow a vegetarian diet for a variety of different reasons. Regardless of your reason, it’s important to be aware of the potential benefits and risks of eliminating meat and/or animal products from your diet. Possible benefits: Possible risks: • Increased fruit and vegetable intake • Challenges in social situations • Decreased saturated fat intake • Nutrient deficiencies • More plant-based protein sources • Excessive dietary restrictions • Increased fiber intake • Inadequate protein resulting in loss of lean body mass • Decreased food cost • Masking symptoms of an underlying eating disorder A vegetarian diet can be a very healthy and nutrient dense diet. However, it does require responsibility, knowledge, and paying attention to ensure that you are getting all of the nutrients your body needs. Some common nutrients that may need extra attention in a vegetarian diet include: Iron A diet lacking this mineral can result in headaches, cold sensitivity, fatigue, and easy bruising. • Look for iron in dark leafy greens especially spinach, beans, soy products, nuts, dried fruit such as raisins, prunes, and apricots, and seeds including pumpkin, hemp, chia, or flaxseed meal* as well as in oatmeal and grains like quinoa and bulgur. • Cooking in a cast iron skillet will increase the iron content of any food. • Plant sources of iron are less easily absorbed. To increase this, couple iron sources with a vitamin C rich food (but not in your cast iron skillet!). Vitamin C sources include citrus fruit and fruit juices, strawberries, broccoli, sweet peppers, kiwi fruit and tomatoes. B-12 A vegan diet lacking this vitamin can cause weakness, anemia, and diarrhea and can in extreme cases ultimately lead to irreversible brain damage.

Abstract: Vegetarianism has gained more visibility in recent years. Despite the well-described effects of a vegetarian diet on health, its influence on the quality of life of the individuals who follow it still needs to be properly investigated. Quality of life relates to a subjective perception of well-being and functionality, and encompasses four main life domains: physical, psychological, social, and environmental. The adoption of a vegetarian diet, despite being a dietary pattern, could potentially influence and be influenced by all of these domains, either positively or negatively. This review aims to present an overview of the background, conceptualization, features, and potential effects of vegetarianism in all quality of life domains. The choice of adopting a vegetarian diet could have positive outcomes, such as better physical health, positive feelings related to the adoption Citation: Hargreaves, S.M.; Raposo, of a morally correct attitude, an increased sense of belonging (to a vegetarian community), and A.; Saraiva, A.; Zandonadi, R.P.

  • Vegetarianism and Human Health
    Vegetarianism and Human Health Usha R. Palaniswamy SUMMARY. Vegetarianism dates back to a time before recorded history and, as many anthropolo- gists believe, most early humans ate primarily plant foods, being more gatherers than hunters. Human diets may be adopted for a variety of reasons, including political, esthetic, moral, environmental and economic concerns, religious beliefs, and a desire to consume a more healthy diet. A major factor influencing the vegetarianism movement in the present time is primarily associated with better health. Epidemiologic data support the association between high intake of vegetables and fruit and low risk of chronic diseases and provide evidence to the profound and long-term health benefits of a primarily vegetarian diet. Vegetables and fruit are rich sources of nutrients, vitamins, minerals, and dietary fiber as well as biologically active nonnutrient compounds that have a complementary and often multiple mechanisms of actions, including antioxidant, anti-inflammatory, hypoglycemic, hypocholesterolemic, and hypolipidemic properties, and mechanisms that stimulate the human immune system. Because of the critical link established between diet and health, consumers have begun to view food as a means of self-care for health promotion and disease prevention. Functional foods are targeted to address specific health concerns, such as high cholesterol or high blood sugar levels, to obtain a desired health benefit. Functional properties identified in a number of plant species have led to a modern day renaissance for the vegetarian movement. t is often asserted that humans are naturally vegetarian because the human body resembles plant eaters, not carnivores. However, Ihumans are omnivores, capable of eating either meat or plant foods, or general feeders, with more generalized anatomical and physi- ological traits.
