In every morsel of food are vitamins, minerals nutrients, and calories that allow our bodies to function properly. Examples of these macronutrients that need to be consumed include: carbohydrates, lipids, proteins, vitamins and mineral. To begin, carbohydrates serve many functions in the body. There are many types of carbohydrates. There are simple carbs, complex carbs, refines unrefined carbs, starch and fiber. Everything that we ingest is broken down; simple carbohydrates are carbohydrates in the smallest form. Simple carbohydrates, or simple sugars, are commonly referred to as monosaccharaides (glucose, fructose, and galactose) or disaccharides, which are 2 simple carbs placed together. Cells use glucose to provide energy for cells through …show more content…
The bad fats are trans fatty acids. Trans fatty acids are created and are saturated fats meaning they have no carbon double bonds. Diets high in saturated fats increase the risk of heart disease. Foods to avoid would are beef, butter, and lard. The good fats are unsaturated fats. These are commonly called monosaturated fats, and polysaturated fats. Diets high in unsaturated fats are, “associated with a lower risk of heart disease” (p.137) Monosaturated fats can been found in avocados, olive and canola oil. Polysaturated fats such as linoleic and alpha-linolenic acid are essential fatty acids because the body is not able to produce them, as described, “they are needed for the formation of the phosopholipid that give cell membranes their structure and functional properties.”(p.138) Cholesterol is needed to, “synthesize other sterols, including vitamin d; bile acids, which are emulsifiers in bile; cortisol, which is a hormone that regulates our physiological response to stress; and testosterone and estrogen, which are hormones necessary reproduction.” (p.140) I am pleased to mention that I met all the requirements for fatty acids and …show more content…
Sodium is, “ important in maintain fluid balance and allowing nerve impulses to travel throughout our bodies, signaling the activities that are essential for life.”(p. 269) Since sodium governs fluid retention it is crucial that is not over consumed. Too much sodium increases fluid retention and the increase fluid volume in the body increase blood pressure or hypertension. Hypertension is a serious condition because it can lead to heart attack, heart failure, and kidney failure. It is vital that people prone to hypertension through genetics or environment maintain a low sodium diet. A DASH diet should be followed and try to stay away from processed food. Conversely insufficient amount of sodium lead to altered mental status, muscle cramps, and loss of appetite. (p.277) Salt alternative such as lemon or lime juice, basil, or garlic may be used as a flavor replacement. Ways to increase electrolyte intake can be done by electrolyte enhanced juices like
High sodium diet: Too much sodium causes fluid retention which increases the workload of the heart. The reason sodium causes water retention is because water moves from low concentrations to high concentrations. Water follows salt so when too much salt is consumed it draws the water from the blood into the tissue.
The slight differences in the way their atoms are arranged give them slightly different properties. These are shown below: α-glucose: β-glucose: Galatose: Fructose: [IMAGE] [IMAGE] The main function of monosaccharide is that they are able to move through bodies, gut walls and therefore important as a source of energy. All other carbohydrates have to be converted to monosaccharides before energy can be released and its is due to it’s small size they are very soluble and it is the form of monosaccharides that all carbohydrates are carried in the blood.
Good fats come from vegetables, nuts, seeds and fish. The two broad categories of beneficial fats include monounsaturated and polyunsaturated fats. The good healthy fats are liquid at room temperature, and do not solidify. They are different from saturated fats as that have fewer hydrogen atoms bonded to their carbon chains.
When one hears the three words: vitamins, nutrients, and minerals, they think of one thing-being healthy and noticing what your intake is daily. Nutrition is all about vitamins and nutrients. Firstly, vitamins are an organic compound required by the body in small amounts of metabolism, to protect health, and for proper growth of children. Vitamins also assist in the formation of hormones, blood cells, nervous systems chemicals, and genetic material. There are 13 well-identified vitamins. Some examples of the 13 well-identified vitamins are: A, D, E, and K-fat contained foods, B, C-consumed immediately. A well known and commonly used in commercials for orange juice vitamin is vitamin C. Vitamin C or ascorbic acid is important in the synthesis and maintenance of connective tissues. The lack of vitamin C will result in a sickness called scurvy. Scurvy harms the gums, mucous membranes, and the skin. Another well-known vitamin and is also used to commercial to give more information about this beverage is the vitamin in milk. The vitamin in milk is vitamin D. If you do not drink milk and obtain this vitamin, your bones and teeth will become soft and weak. Lacking one or more of the 13 well-identified vitamins will cause sickness and weakness to your body. Secondly, nutrients are how the body assimilates certain compounds. Nutrients are classified in 5 major groups: proteins, carbohydrates, fats, vitamins, and minerals. One of the five nutrients is carbohydrate. The carbohydrate group principally consists of sugar, starch, dextrin, cellulose, and glycogen. In more basic terms, carbohydrates are sugars needed by human and other living organisms. Some types of foods that contain carbohydrates would be candies, ice cream, fruit juice, soda, chocolate bars etc. Lastly, vitamins are connected to minerals. Minerals are also a very important part of a healthy person. There are 11 major groups of minerals. They are: calcium, chromium, copper, iodine, iron, magnesium, manganese, phosphorous, potassium, selenium, and zinc. All these terms look very familiar if one has taken chemistry. These are the elements of our world. One of the more common minerals that most people have heard of is calcium. Calcium also helps with the structure and strength of teeth and bones. Vitamins and minerals work together to help humans maintain a healthy body. For example, vitamin D works with calcium to help for and maintain the strength of teeth and bones.
Reduce salt intake. Too much salt impacts the ability of your kidneys to remove water from the bloodstream. The result of this is higher blood pressure because of the extra fluid. Stop using table salt and reduce the amount of salt you use when cooking.
In contrast with the “good fat”, there is also a negative, which is the “bad fat”. Saturated fat, which is considered the “bad fat”, has been linked to high cholesterol and heart disease. It is mostly found in milk and other milk products. Therefore, the low fat diet encourages its participants to reduce saturated fat for it is the main cause of high cholesterol level. On the other hand, even though low carbohydrate diets do not state that carbohydrates are bad; they do state that it causes weight gain; this idea gives most Americans that it is bad because it causes a person to gain weight.
... I was not aware of all the sodium in my food and the 1st thing I will begin doing is seriously reducing the number of processed foods in my diet. I may not be ale to eliminate all since unfortunately it is a lot more convenient to consume it but I will be reducing the amount I have. I can start purchasing fresh, rather than packaged meats. I can also start Compare various brands of the same food item until I find the one that has the lowest sodium content. When I purchase packaged foods at least get ones that say low sodium or sodium free. I can use more herbs in my cooking and switch to Mrs. Dash salt-free seasonings. Lastly, if I’m using canned foods I can rinse them off in water to at least wash some of the sodium off. When it comes to consuming foods with little to no sodium a lot of fresh fruits and vegetables would work since they have “essentially no sodium,"
But when it comes to the effects of saturated fats on health, it is important and how UH while typing. All recent studies have shown that when UH replace fats, triglycerides (fats in the blood) goes down a "good cholesterol" (HDL) goes up. At the same time, the particles of "bad cholesterol" (LDL) are becoming larger, and therefore less dangerous. In other words, a high intake of saturated fat has a detrimental effect on blood fats only if at the same time brings a lot of carbs.
-Fats are good for body energy stores and contribute to healthy development of cells. Good fats are the unsaturated kind, and should comprise
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
A low fat heart healthy diet is my idea of the best nutritional diet, especially since heart disease is the number one killer among people in the United States. Cardiovascular disease is very prevalent in my family. I lost both, paternal and maternal grandparents to heart disease. My father has severe heart disease, and my mother and brother are both hypertensive and require medication; therefore, I know I’m especially vulnerable to this disease.
Saturated fats come from animal sources like steak, hamburger and pork. Unsaturated fats are derived from plants. There are also trans fats that are considered poison for the body. They raise the bad cholesterol in your body, and should never be included in a healthy diet. There are also fatty acids like omega-3 and omega-6 that are good for a healthy body.
Much of my sodium intake came from goldfish crackers, roasted turkey, bagels, and corn with butter and salt. I could reduce my sodium intake by eating food with reduced sodium. Another way I could reduce sodium in my diet is to swap out salty snacks such as crackers with fruits and vegetables.
The most important nutrient categories are starches, minerals, sugars, and electrolytes. Starches and minerals fit into the area of complex carbohydrates. Complex carbohydrates are polysaccharides (many sugars bonded together). Because of the multiple bonds, polysaccharides are able to store energy for later use. Simple sugars make up the other group of carbohydrates. The bonding structures of simple sugars are much less advanced that than those of complex carbohydrates. This allows for the burning of simple sugars in an athlete's body. Electrolytes are a category of their own because they are helpful to an athlete all of the time, whether energy storage or energy burning is needed.
Macros or macronutrients are what we consume this energy for our cells. These are the three men; Carbohydrates, fats and proteins. Each of these macronutrients when broken gives us energy. This energy is in the form of calories.
