Book Synopsis The Plant Paradox by : Dr. Steven R. Gundry, MD
Download or read book The Plant Paradox written by Dr. Steven R. Gundry, MD and published by HarperCollins. This book was released on 2017-04-25 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: From renowned cardiac surgeon Steven R. Gundry, MD, the New York Times bestselling The Plant Paradox is a revolutionary look at the hidden compounds in "healthy" foods like fruit, vegetables, and whole grains that are causing us to gain weight and develop chronic disease. Most of us have heard of gluten—a protein found in wheat that causes widespread inflammation in the body. Americans spend billions of dollars on gluten-free diets in an effort to protect their health. But what if we’ve been missing the root of the problem? In The Plant Paradox, renowned cardiologist Dr. Steven Gundry reveals that gluten is just one variety of a common, and highly toxic, plant-based protein called lectin. Lectins are found not only in grains like wheat but also in the “gluten-free” foods most of us commonly regard as healthy, including many fruits, vegetables, nuts, beans, and conventional dairy products. These proteins, which are found in the seeds, grains, skins, rinds, and leaves of plants, are designed by nature to protect them from predators (including humans). Once ingested, they incite a kind of chemical warfare in our bodies, causing inflammatory reactions that can lead to weight gain and serious health conditions. At his waitlist-only clinics in California, Dr. Gundry has successfully treated tens of thousands of patients suffering from autoimmune disorders, diabetes, leaky gut syndrome, heart disease, and neurodegenerative diseases with a protocol that detoxes the cells, repairs the gut, and nourishes the body. Now, in The Plant Paradox, he shares this clinically proven program with readers around the world. The simple (and daunting) fact is, lectins are everywhere. Thankfully, Dr. Gundry offers simple hacks we easily can employ to avoid them, including: Peel your veggies. Most of the lectins are contained in the skin and seeds of plants; simply peeling and de-seeding vegetables (like tomatoes and peppers) reduces their lectin content. Shop for fruit in season. Fruit contain fewer lectins when ripe, so eating apples, berries, and other lectin-containing fruits at the peak of ripeness helps minimize your lectin consumption. Swap your brown rice for white. Whole grains and seeds with hard outer coatings are designed by nature to cause digestive distress—and are full of lectins. With a full list of lectin-containing foods and simple substitutes for each, a step-by-step detox and eating plan, and delicious lectin-free recipes, The Plant Paradox illuminates the hidden dangers lurking in your salad bowl—and shows you how to eat whole foods in a whole new way.

Book excerpt: The Lectins: Properties, Functions, and Applications in Biology and Medicine is a 10-chapter text that deals with the advances in research studies on the properties, functions, and applications of lectins in biology and medicine. The first two chapters consider the historical development, physicochemical properties, isolation, and remarkable specificity toward sugars of lectins. These topics are followed by a discussion on the molecular aspects of protein evolution, with a particular emphasis on lectins, which provide an excellent example of a family of homologous proteins. The following chapters explore the diverse biological activities of lectins and how these properties are utilized for the isolation and characterization of carbohydrate-containing compounds in solution and on cells. A chapter focuses on the functions of lectins in their natural milieu. This text further covers the importance of lectins in nonplant systems as exemplified by lectins that occur in vertebrates, slime molds, and bacteria. The last chapter highlights the nutritional significance of the occurrence of lectins in plant foods such as legumes. This book is an ideal source for organic chemists, protein researchers, and workers in the fields of biology and medicine.

Download or read book Plant Lectins written by A. Pusztai and published by Cambridge University Press. This book was released on 1991 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and pharmacological properties of lectins. Lectins, which are most commonly found in plants, are widespread natural products with striking biological activities. Their specific ability to recognise and bind to simple or complex saccharides facilitates their role as effective information protein molecules. As agents of cell-to-cell recognition, lectins promote symbiosis between plants and specific nitrogen-fixing soil bacteria. As natural defensive molecules, they can protect plants against predators such as bacteria, fungi and insects. As part of our diet, lectins are powerful exogenous growth factors in the small intestine and influence our health, the digestive function and the bacterial ecology of the alimentary tract. Lectins are also important research tools in preparative biochemistry and cell science.
Download or read book Lectins written by Nathan Sharon and published by Springer. This book was released on 2012-11-12 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: A characteristic property of most, or perhaps all, proteins is their ability to combine specifically and reversibly with various substances. Well known examples are enzymes that bind substrates and inhibitors, and antibodies that bind antigens. This book deals with lectins, a class of proteins that bind carbohydrates. Another characteristic property of lectins is that they agglutinate cells or precipitate polysaccharides and glycoproteins. This is because lectins are polyvalent, i.e. each lectin molecule has at least two carbohydrate binding sites to allow crosslinking between cells (by combining with sugars on their surfaces) or between sugar containing macromolecules. The agglutinating and precipitating activities of lectins are very similar to those of antibodies. They can likewise be specifically inhibited by low molecular weight compounds (haptens), which in the case of lectins are sugars or sugar containing compounds (Fig. 1.1). Not surprisingly, therefore, many of the methods used in lectin research are based on immunochemical techniques. Nevertheless, lectins are different from antibodies in several important aspects. Many lectins are found in plants, microorganisms and viruses, which do not synthesize immunoglobulins. In fact, they are found in almost all living organisms (Table 1.1) and are not confined to specific organs or tissues. Another marked difference between the two classes of compound is that antibodies are structurally similar, whereas lectins are structurally diverse. In general, lectins are oligomeric proteins composed of subunits, usually with one sugar binding site per subunit.
Book Synopsis Lectins and Glycobiology by : Hans-Joachim Gabius
Download or read book Lectins and Glycobiology written by Hans-Joachim Gabius and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intriguing complexity, precision, and regulation of the wide range of biologi cal processes is determined by intricate mechanisms of molecular recognition. Their nature is under intense scrutiny. In addition to the well-appreciated interac tion of proteins either with amino acid or nucleotide sequences, the investigation of their interplay with carbohydrate elements of cellular glycoconjugates current ly exerts increasing attraction. In the group of carbohydrate-binding proteins, lec tins are distinguished from antibodies or ligand-affecting enzymes, according to the most recent definition. The thorough analysis of their structure and function is considered as a focus to collect a critical mass of information for delineating details of a further array of biochemical processes with pivotal physiological im pact. Following an already century-long history of scientific description, reflected by subjectively chosen highlights (see the Brief History of Lectin Research at page VI), the excitement in glycobiological research that prevails today can easily be ex plained by our growing awareness of the multifarious significance of a sugar-code system of biological information. This present notion unmistakably has an im pact on lines of research in diverse disciplines like cell and molecular biology, histochemistry, or clinical sciences. It also prompts inherent practical questions such as how to obtain lectins, or how to employ them as instruments in various assay systems with the best possible results. Thus, this book is devoted intentionally to cover the techniques in different research fields that deal with lectins.

Book Synopsis What Are Lectins, The Dangers And Health Effects Of Consuming Foods That Are High In Lectins, How To Minimize Your Lectin Intake When Eating Lectin-Rich Foods, And The Lectin-Rich Foods That You Should Avoid Eating by : Dr. Harrison Sachs
Download or read book What Are Lectins, The Dangers And Health Effects Of Consuming Foods That Are High In Lectins, How To Minimize Your Lectin Intake When Eating Lectin-Rich Foods, And The Lectin-Rich Foods That You Should Avoid Eating written by Dr. Harrison Sachs and published by The Epic Books Of Dr. Harrison Sachs. This book was released on 2020-04-07 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essay sheds light on what are lectins, demystifies the dangers and health effects of consuming foods that are high in lectins, elucidates how to minimize your lectin intake when eating lectin-rich foods, and reveals the lectin-rich foods that you should avoid eating. Lectins are carbohydrate-binding proteins that are a type of antinutrient. “Lectins are deemed to be diverse family of carbohydrate-binding proteins found in all plants and animals. Some plant lectins are even considered toxic. For instance, in the case of the poison ricin, a lectin from the castor oil plant, they can be lethal” (Leech, 2019). There are a cornucopia of disparate types of lectins. The different types of lectins are not limited to “plant lectins and animal lectins”. Other types of lectins encompass “bacterial lectins, fungal lectins, and algal lectins”. The classifications of plant lectins encompass “merolectins, hololectins, superlectins, and chimerolectins”. Lectins can also serve as a type of insecticide. “The binding of lectins to glycosylated proteins at the midgut of insect larvae interfere with the nutrient uptake and the efficiency of diet utilization, resulting in a drop in mass gain. In this sense, lectins are insecticides that promote mortality or delay development of insects”. The inhibition of the absorption of nutrients in the gut epithelium can culminate in insects being deprived of their lives. It can be deduced that consuming lectin-rich foods cannot only be deleterious to human beings, but can also be inimical to insects and animals. Lectins are pervasive in a myriad of disparate types of foods. Lectins are pervasive in whole grains, legumes, nuts, seeds, fruits, vegetables, and unfermented soy products. The intake of lectin-rich foods can induce acute digestive distress. “For example, raw kidney beans contain phytohaemagglutinin, a toxic lectin. The main symptoms of kidney bean poisoning are severe abdominal pain, and vomiting”. It can be poisonous to ingest phytohaemagglutinin which is embedded in raw kidney beans. People should abstain from consuming kidney beans. The consumption of lectin-rich foods can adversely impinge on “gastrointestinal tract health”. The consumption of lectin-rich foods can elicit a multitude of adverse gastrointestinal health issues. The digestive enzymes of the vessel are unable to dismantle lectins. This is because “lectins are highly resistant to your body’s digestive enzymes”. Lectins are able to “easily pass through your stomach unchanged”. Lectins are able to bind to carbohydrates in the vessel and ‘“interrupt messaging between cells or otherwise cause toxic or inflammatory reactions’. ‘Since lectins are resistant to human digestion, it is believed that they interfere with the proper absorption of vitamins, minerals and some key proteins’” (Colino, 2017). Lectins are noxious antinutrients that adversely impinge on the vessel’s ability to absorb nutrients into the gastrointestinal tract. The consumption of lectin-rich foods can trigger adverse autoimmune reactions in the vessel. “Lectins tend to be clingy in the gastrointestinal tract and can attach to the intestinal wall” (Colino, 2017). If the lining of your intestines is permeable, then “lectins to slip into the bloodstream, which can trigger an inflammatory response and/or the production of antibodies to lectin” (Colino, 2017). The intake of lectin-rich foods cannot only induce gastrointestinal distress, but can also ravage the gut wall. The decimation of the gut wall contributes to the development of “easily permeable gut lining”. Furthermore, the ingestion of lectin-rich foods can also induce nausea and vomiting. The consumption of lectin-rich foods renders a person at a higher probability to contract leaky gut syndrome. Contracting leaky gut syndrome renders a person at a higher probability to contract an autoimmune disease, such as “lupus and rheumatoid arthritis. Studies in medical journals, such as the Lancet, the British Medical Journal and the International Journal of Gastroenterology have suggested that leaky gut causes autoimmune diseases, such as lupus and rheumatoid arthritis, and many other diverse health issues, including allergies, autism, depression, eczema, psoriasis, metabolic syndrome, and possibly many more diseases that are now being seen as autoimmune conditions for the first time”. Contracting leaky gut syndrome renders a person at a higher probability to contract an inimical inflammatory disease.

Book excerpt: Lectins form a ubiquitous and important class of natural carbohydrate- binding information proteins. Although the main scientific interest was originally focussed on toxic lectins such as ricin, recent emphasis has shifted to exploring their involvement in cell-to-cell communication and recognition in microorganisms, plants and animals.; As knowledge of the basic properties and biological activities of lectins has increased, exciting opportunities have arisen for the exploitation of some of the advantageous aspects of fundamental lectinology.; "Lectins: Biomedical Perspectives" records the major achievements of an initiative, funded by the European Community, to coordinate lectin research throughout Europe.
Book Synopsis Lectin in Host Defense Against Microbial Infections by : Shie-Liang Hsieh
Download or read book Lectin in Host Defense Against Microbial Infections written by Shie-Liang Hsieh and published by Springer Nature. This book was released on 2020-03-09 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book systemically presents the latest research on lectins, covering all the major topics in the field, including the heterocomplex of lectins and Toll-like receptors, protective versus pathogenic functions in connection with microbial infections, and novel strategies for enhancing host immunity against infectious diseases caused by viruses, bacteria, and fungi. Lectins are a large group of glycan-binding proteins that recognize diverse glycan and non-glycan structures expressed on prokaryotic and eukaryotic cells, and are vital to cell-cell interactions, the attachment of microbes to host cells, and the recognition and activation of immune responses to exogenous and endogenous danger signals. The composition and structure of microbes are complex and include numerous ‘pathogen-associated molecular patterns’ or ‘damage-associated molecular patterns’. As such, microbes’ interactions with immune cells activate multiple innate immunity receptors and produce distinct inflammatory reactions, which can be protective to contain microbial invasion, or pathogenic to cause tissue damage and shock syndrome in the host. The book shares lessons learned from state-of-the art research in this field, highlights the latest discoveries, and provides insightful discussions on lectin-mediated inflammatory reactions, while also outlining future research directions.
