 So, “How are you feeling? Are you in a good mood, positive, focused and have a lot of energy? Or are you depressed, moody, stressed and cant sleep at night?
Do you engage is social activities, are you affectionate and outgoing? Or are you lonely, withdrawn and do people tend to annoy you? Are you in control of your food cravings and your weight? Or do you crave carbs, sugar or salt and are you putting on more and more belly fat? So how do you really feel? It is a direct correlation of the balance in your body. Your habits and lifestyle choices are both a cause and effect of this chemical and hormonal balance. Neurotransmitters and hormones are involved in almost every function of the body, and both are critically important for our mental health and well being. If ether one of the systems gets out of balance your health will spiral down leaving you tired, depressed, and overweight! Lets take a look at these two systems, how they work and how they effect your thoughts and feelings. Our endocrine system (hormones) is essentially the command center in our brain; the hypothalamus and pituitary glands send signals to distant parts of the body to control everything from stress response through our adrenal glands, to blood sugar balance through our pancreas, to thyroid hormone through our thyroid gland, to sexual behavior and function through our reproductive organs. Hormones also control growth, sleep, mood and much more. The nervous system (neurotransmitters) send messages throughout the body to every cell, organ and tissue helping you do everything from movement to feeling happy, angry or sad. Neurotransmitters are responsible for providing energy, motivation, focus as well as calming the mind and body, slowing down the system, and inducing sleep. Lets take a look at a few: Serotonin Dopamine Oxytocin Testosterone Estrogen Serotonin is formed from a biochemical conversion process that combines tryptophan, which is an amino acid from protein; with tryptophan hydroxylase, a chemical reactor, together form 5-hydroxyltryptamine (5-HT). Serotonin is most well know for its role in the brain where it plays a major part in mood, anxiety, and happiness. Dopamine is a neurotransmitter that helps control the brains reward and pleasure centers. Dopamine also helps regulate movement and emotional responses, and it enables us not only to see rewards, but also to take action to move toward them. Tyrosine, another amino acid becomes dopa via the enzyme tyrosine hydroxylase, and dopa becomes dopamine via the actions of dopa decarboxylase. (One more chemical reaction can turn dopamine into the neurotransmitter, norepinephrine. Dopamine is one of the key regulators of decisions, or impaired decision making as seen in people with dopamine related disorders such as addiction, schizophrenia and Parkinson’s disease. Oxytocin is a hormone that is made in the hypothalamus located in the brain. It is transported to, and secreted by, the pituitary gland which is located at the base of the brain. It is classed as a nonpaeptide (a peptide containing nine amino acids), while its biological classification is as a neuropeptide. It acts both as a hormone and as a brain neurotransmitter. Oxytocin when released into defined regions of the brain affects emotional, cognitive, and social behaviors. It contributes to relaxation, trust, human connections, and Psychological stability Testosterone is the primary male sex hormone and an anabolic steroid. Testosterone plays a key role in male development of reproductive tissues such as the testis and prostate along with promoting secondary characteristics such as increased muscle and bone mass. In addition, testosterone is essential for health and well-being, and psychological behavior. Testosterone levels play a major role in risk-taking personality traits and many studies support a link between adult aggressive and antisocial behavior although the relationship is modest if examined separately for each sex. Estrogen is the primary female sex hormone. It is responsible for the development and regulation of the female reproductive system and secondary sex characteristics. Studies show that the overall level of an individual’s impulsivity is affected by estrogen. Those with lower estrogen levels in the first show higher measures of trait impulsivity. So put this into context; a question recently posed to me is what inspired me to write this. The question was, “I wonder why some people just naturally have a propensity for addictive behaviors or think nothing about joining the military…how can someone not fear having to fight?" Personality traits can be measured and altered based on the chemical and hormonal makeups. So many things can either enhance or hinder this balance. Our philosophy is…”when you address and balance three main fundamental foundations for life, you can truly provide perfect harmony and optimal wellness."

Genetically modified foods or GM foods are foods produced from organisms that have had specific changes introduced into their DNA using the methods of genetic engineering. These techniques allow for the introduction of new traits as well as greater control over traits than previous methods such as selective breeding and mutation breeding. Commercial sale of genetically modified foods began in 1994.
Scientists discovered in 1946 that DNA can transfer between organisms. The first genetically modified plant was produced in 1983, using antibiotic-resistant tobacco. In 1994, the transgenic Flavr Savr tomato was approved by the FDA for marketing in the US. The modification allowed the tomato to delay ripening after picking. In the early 1990s, recombinant chymosin was approved for use in several countries. In the US in 1995, the following transgenic crops received marketing approval: canola with modified oil composition. In 2000, with the creation of golden rice, scientists genetically modified food to increase its nutrient value for the first time. As of 2011, the US is the leading country in the production of GM foods. Twenty-five GM crops had received regulatory approval. As of 2013, roughly 85% of corn, 91% of soybeans, and 88% of cotton produced in the US are genetically modified. Foods that include modified DNA and/or protein include fruits, vegetables, corn and soy. Corn and soy are also consumed after modifications that remove most/all DNA/protein. Fruits and vegetables Papaya was genetically modified to resist the ringspot. The New York Times stated, "in the early 1990s, Hawaii’s papaya industry was facing disaster because of the deadly papaya ringspot virus. Its single-handed savior was a breed engineered to be resistant to the virus. Without it, the state’s papaya industry would have collapsed. The New Leaf potato, brought to market by Monsanto in the late 1990s, was developed for the fast food market, but was withdrawn in 2001 after fast food retailers rejected it and food processors ran into export problem As of 2005, about 13% of the Zucchini (a form of squash) grown in the US was genetically modified to resist three viruses; that strain is also grown in Canada In 2011, BASF requested the European Union Food Safety Authority's approval for cultivation and marketing of its Fortuna potato as a feed and food. In February 2013, BASF withdrew its application. In 2013, the USDA approved the import of a GM pineapple that is pink in color and that "overexpresses" a gene derived from tangerines and suppress other genes, increasing production of lycopene. The plant's flowering cycle was changed to provide for more uniform growth and quality. The fruit "does not have the ability to propagate and persist in the environment once they have been harvested," according to USDA APHIS. According to Del Monte's submission, the pineapples are commercially grown in a "monoculture" that prevents seed production, as the plant's flowers aren't exposed to compatible pollen sources. Importation into Hawaii is banned for plant sanitation reasons In 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains 10 genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made, via RNA interference.[30][31] In February 2015 Arctic Apples were approved by the USDA,[32] becoming the first genetically modified apple approved for sale in the United States.[33] Gene silencing is used to reduce the expression of polyphenol oxidase (PPO), thus preventing the fruit from browning.[34] Corn Corn used for food has been genetically modified to tolerate various herbicides and to express a protein from Bacillus thuringiensis (Bt) that kills certain insects.[35] About 90% of the corn grown in the US has been genetically modified.[36] Corn can be processed into grits, meal and flour as an ingredient in pancakes, muffins, doughnuts, breadings and batters, as well as baby foods, meat products, cereals, and some fermented products. Masa flour is variety of flour that is produced using the alkaline-cooked process. A related product, masa dough, can be made using corn flour and water. Masa flour and masa dough are used in the production of taco shells, corn chips, and tortillas.[37] Soy Genetically modified soybean has been modified to tolerate herbicides, express Bt, and produce healthier oils.[36] About 90% of soybeans in the US are genetically modified.[38] Soybeans contain about 20% oil. In the most common method used to extract the oil, the soybeans are cracked, adjusted for moisture content, rolled into flakes and solvent-extracted with commercial hexane. The remaining soy meal has a 50% soy protein content. The meal is 'toasted' (a misnomer because the heat treatment is with moist steam) and ground in a hammer mill. Ninety-eight percent of the US soybean crop is used for livestock feed. Part of the balance is processed further into high protein soy products that are used in a variety of foods, such as salad dressings, soups, meat analogues, beverage powders, cheeses, nondairy creamer, frozen desserts, whipped topping, infant formulas, breads, breakfast cereals, pastas, and pet foods.[39][40] Processed soy protein appears in foods mainly in three forms: soy flour, soy protein isolates and soy protein concentrates.[40][41] Food-grade soy protein isolate first became available on October 2, 1959 with the opening of Central Soya's edible soy isolate production facility on the Glidden Company industrial site in Chicago.[42]:227–28 Soy protein isolate is a highly refined form of soy protein with a minimum protein content of 90% on a moisture-free basis. It is made from soy meal that has had most of the fats and carbohydrates removed. Soy isolates are mainly used to improve the texture of processed meat products and to increase protein content, enhance moisture retention, and as an emulsifier.[43][44] Soy protein concentrate is about 70% soy protein and is basically soybean meal without carbohydrates. Soy protein concentrate retains most of the bean fiber. It is used as a functional or nutritional ingredient in a wide variety of food products, mainly in baked foods, breakfast cereals and in some meat products. Soy protein concentrate is used in meat and poultry products to increase water and fat retention and to improve nutritional values (more protein, less fat).[43][45] Soy flour is made by grinding soybeans into a fine powder. It comes in three forms: natural or full-fat (contains natural oils); defatted (oils removed) with 50% protein content and with either high water solubility or low water solubility; and lecithinated (lecithin added). As soy flour is gluten-free, yeast-raised breads made with soy flour are dense in texture. Soy grits are similar to soy flour except the soybeans have been toasted and cracked into coarse pieces. Kinako is a soy flour used in Japanese cuisine.[43][46] Textured soy protein (TSP) is made by forming a dough from meal with water in a screw-type extruder, and heating with or without steam. The dough is extruded through a die into various shapes and dried in an oven. The extrusion technology changes the structure of the soy protein, resulting in a fibrous, spongy matrix similar in texture to meat. TSP is used as a low-cost substitute in meat and poultry products.[43][47] Derivative products Corn starch and starch sugars, including syrups Starch or amylum is a polysaccharide is produced by all green plants as an energy store. Pure starch is a white, tasteless and odourless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. To make corn starch, corn is steeped for 30 to 48 hours, which ferments it slightly. The germ is separated from the endosperm and those two components are ground separately (still soaked). Next the starch is removed from each by washing. The starch is separated from the corn steep liquor, the cereal germ, the fibers and the corn gluten mostly in hydrocyclones and centrifuges, and then dried. This process is called wet milling and results in pure starch. The products of that pure starch contain no GM DNA or protein.[48] Starch can be further modified to create modified starch for specific purposes,[49] including creation of many of the sugars in processed foods. They include:
An example of a phosphatidylcholine, a type of phospholipid in lecithin. Red - choline and phosphate group; Black - glycerol; Green - unsaturated fatty acid; Blue - saturated fatty acid Corn oil and soy oil, already free of protein and DNA, are sources of lecithin, which is widely used in processed foods as an emulsifier.[51][52] Lecithin is sufficiently processed that protein or DNA from the original crop from which it is derived is often undetectable with standard testing practices.[48] Nonetheless, consumer concerns about GM food extend to such products.[53] This concern led to policy and regulatory changes in Europe in 2000, when Regulation (EC) 50/2000 was passed[54] which required labelling of food containing additives derived from GMOs, including lecithin. Because of the difficulty of detecting the origin of derivatives like lecithin with current testing practices, European regulations require those who wish to sell lecithin in Europe to employ a comprehensive system of Identity preservation (IP).[55][56] Sugar The US imports 10% of its sugar from other countries, while the remaining 90% is extracted from domestically grown sugar beet and sugarcane. Domestically grown sugar crops come half from beet, and the other half from cane. After deregulation in 2005, glyphosate-resistant sugar beet was extensively adopted in the United States. 95% of beet acres in the US were planted with glyphosate-resistant seed in 2011.[17] Herbicide-tolerant beets are also approved in Australia, Canada, Colombia, EU, Japan, Korea, Mexico, New Zealand, Philippines, Russian Federation and Singapore.[57] The food products of sugar beets are refined sugar and molasses. Pulp from the refining process is used as animal feed. The sugar produced from GM sugarbeets contains no DNA or protein—it is just sucrose, chemically indistinguishable from sugar produced from non-GM sugarbeets.[48][58] Vegetable oil Most vegetable oil used in the US is produced from GM crops canola,[59] corn,[51][60] cotton[61] and soybeans.[62] Vegetable oil is sold directly to consumers as cooking oil, shortening and margarine[63] and is used in prepared foods. There is a vanishingly small amount of protein or DNA from the original crop in vegetable oil.[48][64] Vegetable oil is made of triglycerides extracted from plants or seeds and then refined and may be further processed via hydrogenation to turn liquid oils into solids. The refining process[65] removes all, or nearly all non-triglyceride ingredients.[66] Adapted from wikipedia Calcium has a “claim to fame” in regards to osteoporosis and bone health. The two are synonymous for calcium supplement usage. Approximately 99% of our body’s calcium is within our bones and teeth. Calcium is also essential for muscle contractions and proper nerve function to conduct impulses. It is one of the most abundant minerals in our body. When asked, many people will say they take calcium supplements. An increased amount of calcium is not the end all solution for osteoporosis. There are several issues that determine the absorption of calcium in the body, and too much calcium can be dangerous.
Osteoporosis is a progressive disease in which your bones become weaker which causes changes in posture and makes you extremely susceptible to bone fractures. The term osteoporosis means porous bones. There are many factors that can contribute to osteoporosis, not just low calcium intake, most of which we have direct control over: · Poor dietary habits (low calcium intake, poor vitamin D absorption, high protein diets) · Excess alcohol consumption · High caffeine intake · Lack of exercise · Cigarette smoking Another important role of calcium that will be of interest to you bodybuilders and sports enthusiasts is in relation to muscle contraction. When you decide to move, a nerve impulse activate muscles, the impulse is transmitted through what is called the motor endplate of the muscle. The action quickly spreads over the surface of the muscle cell. Contraction of all myofibrils within the muscle takes place instantly. When excitation reaches the point of contact deep within the muscle cell calcium is released into the cytoplasm and reacts with troponin, a protein substances within the muscle, and contraction occurs. After you decide to relax, the impulse is no longer required, calcium is pumped back and tropomyosin, another protein substance, enters the binding site and relaxation occurs. It really is an amazing process that we take for granted. There is much more to this, but I don’t want to lose your interest. Unless you enjoy the technical information, it can be rather confusing or boring. Just realize the importance of calcium in regards to us being able to move properly, not even to mention to exercise properly. Too much calcium however, can be dangerous. It can cause formation of kidney stones, mental confusion, muscle or abdominal pain and hinder the absorption of Iron. The recommended amount of calcium daily is 1000 – 1200mg per day. Do not consume this amount all at once. Break it up evenly throughout the day. If you are using supplemental calcium, be sure to discuss with your doctor, because calcium can interfere with certain medications. Men with prostate cancer should not take calcium supplementation There are many different forms of calcium and also debate on which is the best absorbed. Calcium carbonate appears to have the most elemental form of calcium, but may not be absorbed as well as calcium citrate according to several studies. Calcium hydroxyapatite has been shown to improve bone mass, but absorption appears to be poor. Good food sources of calcium are milk and milk products, sardines, tofu, broccoli and green leafy vegetables. However, green leafy vegetable especially spinach have oxalic acid which interferes with absorption. Cocoa also contains oxalates, so when you add to your milk, you interfere with absorption. So if you are consuming milk for your calcium, drink it plain. |
