Pros and Cons of Dietary Supplements



name is Elena and I am presenting on the pros and cons of supplements and I'm specifically going to talk about vitamin supplement scenes that are mostly most commonly used today I would like to start off my presentation with some statistics that are found in my research so supplements are a powerful industry and they make about 18 billion in sales per here most of the cells are vitamin and mineral products and some studies suggest that fifty to seventy percent of athletes use some type of dietary supplement now I'm now going to talk about performance-enhancing supplements I came across these statistics when I was doing my research so approximately 50 to twenty-five percent of supplements do have some illegal ingredient or banned substance approximately 400,000 12 to 14 year old errs have used performance-enhancing substances and approximately 500,000 eighth eighth eighth graders have used steroids now this shows that it is normal for our society today to take pills without unit a lot of thought it is important to differentiate between nutritional supplements and drugs because the food and drug administration has different perspective when it comes to regulating and controlling this product dietary supplements contain concentrated sources of vitamin mineral sometimes herbs and other ingredients and drugs are defined as products that exceed the maximum value of mineral and in content you can also can cause some side effects for that reason there are more strictly regulated and controlled by the Food and Drug Administration that drugs are and actually some studies that i came across claim that dietary supplements do not have to be approved by the Food and Drug Administration to before they're sold alright so far violins violins are organic compounds required by the body in small amounts they have as metabolic catalysts that regular regular chemical reactions within your body and your body cannot manufacture synthesized by means except one vitamin D which is why the mask rotate through diet or perhaps supplements also vitamins did not provide energy in other words they don't supply the body with calories and it is important to emphasize this because a lot of people will claim that when they take a multivitamin they feel better it gives them more energy helps them get through the day and this is somewhat misleading because vitamins tune or provide energy also many athletes think that exercise increases their vitamin needs but exercises non-brand vitamins and also because we intend to eat more therefore the consume more vitamins there are two types of vitamins fat soluble and water-soluble the difference between the two groups is very important as it determines how vital mean outs in the body so what I solve a lot of vitamins can dissolve in the water and your character the body's issues but are not stored in the body fat soluble vitamins are usually absorbing fat loss rules and are stored in body tissues this means that if a person takes in too much of a fat-soluble vitamin over time they can have too much of that vitamin per cell in the body and can potentially lead to a dangerous condition called hypervitaminosis which can be very toxic and the role of vitamins I love outlined a few points over here they can assist in proper cell division we can help convert fruits to energy and they fight free radicals which our bodies are constantly exposed to however in general the water-soluble vitamins act as coenzymes in metabolic processes in each of the fat-soluble vitamin groups contains several related compounds that have biological activity so this picture over here just summarizes that when vitamins enter the body the system they don't act alone they need to add the need to UM the need carbohydrates Vong other substances proteins and fats in order to provide the body with benefits in the and convert food to energy specifically these vitamins B vitamins okay so dietary supplements are appropriate for individuals who are at risk of nutritional deficiencies specifically individuals who abstain from eating any animal foods may become deficient deficient in vitamin b12 d riboflavin iron and zinc people have void dairy for because you're lactose intolerant can become deficient in riboflavin and calcium individuals who follow a strict diet and consume less than 1,200 calories may miss out on some important nutrients and also people who are allergic to certain foods and they need to compensate with alternating vitamin sources as well as spreading women there is a research that they do require additional vitamins however always individuals should consult with their physicians first prior to taking supplements now as I have mentioned already many people think that supplements can make up for their and healthy lifestyle or that it will satisfy hundred percent of their nutritional needs however this is not true and advertisements generally downplay the importance of food so priority should have the fundamental foods then supply the vitamins and other nutrients before turning to supplements and consumers need to be aware that large large doses of vitamin A de in case of the fat soluble can be harmful to to health and it can cause toxicity specifically high doses of vitamin A can cause fatigue nausea loss of appetite bone and joint pains and headaches large doses of vitamin D can cause eating problems and can cause coma and death and large doses of vitamin E can cause block coding and large doses of vitamin K may resolve liver damage and anemia now another issue with supplements is a purity composition and the quality a lot of companies claim that their products are natural they're organic but apparently violence can be later labeled as natural even if they contain as little as ten percent of their natural form of the bottome and one study the deep chemical analysis on a number of supplements identified more than 560 products containing synthetic pharmaceutical compounds including stimulants steroids and antidepressants also many vitamins are synthetic which means that synthetic versions on vitamins contain chemical compounds that were not meant for human consumption because you don't occur naturally in some cases the body will not absorb synthetic vitamins the same way as the natural ones although they do mimic the way natural vitamins up in our bodies that's why they may can benefit some some people also many synthetic body means like the transporters and cofactors associated with naturally with natural-appearing vitamins because they have been isolated also other issues are obviously the chemicals that can exist in supplements such as mercury petroleum extracts coal-tar derivatives preservatives acids and other chemicals and just to conclude my presentation supplements can be beneficial for for certain populations but the consumers need to be smart need to be aware of the hazards on the side of nope there are consequences of the high doses of the supplements if they're taken e they need to read the label because that's where they can find out what ingredients it is made of however as I mentioned the food and drug administration does not control the master class drugs and there are many dishonest suppliers so we actually don't don't always know what's in a supplement and this is just to conclude mud to end of my presentation even if a salesperson tells you that this album is hundred percent organic well organic also means that it's a carbon-containing substance so therefore or all petroleum derivatives are organic too and thank you very much
