Fats are often thought of as all being bad when, in fact, fats are a very important part of our diet. All fats - the good, bad, and ugly - are important to have every single day. The good, bad, and ugly should all be limited, the bad and the ugly just more than the good. Limiting your bad and ugly fats is key because you already consume enough in your daily diet and additional amounts can lead to health problems. Monounsaturated fats, polyunsaturated fats, and fatty acids are all good fats that should be a large part of your diet, but - just like with bad and ugly - limited. Saturated fats are the main type of bad fat and ugly fats usually lead to clogged arteries. The good needs the bad and the ugly so trying to cut out the two from ones diet will not be helpful. When it comes down to it, all fats are basically good in moderation.
ReplyDeleteFats are important because it performs many metabolic tasks. The human body's cell membrane, retina, hormones, joints, nerves, etc., need fat. Fats are good because they can help protect and keep us warm. Good fats, like monounsaturated fat, is in oil. Olive oil (which contains alot of monounsaturated fat) helps prevent coronary disease. Monounsaturated fat is also in canola, peanut, avocado, nuts and seeds oils. Polyunsaturated fat is a good fat. This fat is mainly in sunflower, corn, and soy. Polyunsaturated is good for cholesterol. The bad fats, such as saturated fat, can ruin the cardiovascular system. Saturated fat can be found in coconut oil, palm oil, nuts oil and vegetable oils. The human body can't live without bad fat, but its not good to eat more than 10% of our calorie intake.
ReplyDeleteFats are important because our cells need them. There are many different kinds of fats; there are good fats, bad fats and ugly fats. The good fats have omega-3, omega-6 and oils. The bad consists of only saturated fat. The ugly fats are trans-fat and saturated fats. Fats are good for us beacause it has omega-3 and omega-6 which is need for our cells. Fats are also bad for you because of trans-fat ans saturated fat. They can clog your artries and you can get a heartattack. So, watch what you eat.
ReplyDeleteFats are important as they are significant in biological structures and operations. They also execute many serious metabolic tasks. Some of those that need fat are cell membranes, hormones, retina, joints, and nerves.
ReplyDeleteThere are two kinds of fats: the good and the bad. Monosaturated fats, polyunsaturated fats, and essential fats are examples of good fats. But, too much of good fats can cause trouble; it can cause death. Too much fat also increases one's cholesterol.
Although labeled as terrible for you, not all fat is bad. In fact, your body actually needs some kinds of fat. The most important of these healthy fats are Omega 6 and Omega 3 fatty acids. Although you consume a lot of Omega 6 each day, Omega 3 is harder to come by. As it is mostly present in fish, many people take Omega 3 supplements. Also, the bad, saturated fats that make things taste so good are ok in small amounts. However, over consumption of these fats are very unhealthy for you. Worst of all are transfats. These fats are totally artificial and are in no way good for you. As they come in such a wide variety, ranging from the essential to the dangerous, you must be careful which ones you eat.
ReplyDeleteFat is very important in our diet, yet too much of it can cause problems. It helps our body function properly ( if kept at a balance) and can even prevent disease. Olive oil for example contains a monounsaturated fat which helps prevent coronary disease.Polyunsaturated fats are good too but most of them have been processed almost beyond recognition, and has been stripped of its nutrients. Saturated fats on the other hand are unhealthy and if they're not consumed moderatly they can cause heart problems.
ReplyDeleteFats are important for many different reasons, but mainly its nutritional values. It is one of the three major macronutrient components in our diet. It is also fundamental in biological structures and functions, as well as performing many serious metabolic tasks. Cell membranes, hormones, retinas, joints, and nerves all need fats. They are good because our body needs a good balance of Omega-6 and Omega-3 fatty acids. As Americans, we have a ratio of approximately 10:1, which is excrutiatingly bad, considering that the normal ratio is 1:1. Fats are also bad. They are bad because they cause cause havoc on our cardiovascular systems. Also, because an unwatched diet can result in high numbers of saturated fats. This can lead to raised cholesterol, reduced HDL-cholesterol, or increased LDL-cholesterol, all leading to a higher risk of a cardiac occasion. So, fats can be good, but don't have too many, or there will be consequences.
ReplyDeleteGenerally people tend to think all fat is bad for you, but thats not the case. Our bodies need fat in order to preform serious metabolic tasks. Cell membranes, hormones, retina, joints, and nerves all need fat. The body needs at least 23grams of olive oil a day to prevent coronary desease. Saturated fats from animals , have been blamed for the recking of a person's cardiovascular system. A extreme increase of cholesterol can kill, but we need cholesterol to live. The key is to balance our fat.
ReplyDeleteFats are fundamental in biological structures, functions and performs many metabolism tasks. Cell membranes, hormones (both good and bad), nerves, joints and retinas all need fat. Dietary fat is also needed for transport and absorption of many fat soluble vitamins. However, too much or too little can greatly affect our health.
ReplyDeleteSome good fats are olive oil (monounsaturated fats), most vegetable oils (polyunsaturated fats) and omega-3 and omega-6 (fatty acids). Monounsaturated fats contain a lot of vitamins and antioxidants, which helps lower the "bad" LDL-cholesterol. It also helps raises the "good" LDL-cholesterol and reduce the impact of LDL-cholesterol oxidation. Omega-3 and Omega-6 are involved in maintaining cell membrane integrity, hormones, immunity and regulates inflammatory responses. Studies have shown that these fatty acids can lower the risks of cardiovascular diseases. Omega-3 also plays an important role in brain and eye development, asthma, memory loss, mood elevation, joint inflammation, eczema and macular degeneration.
Even though some fats may taste good, consuming to much can lead to serious health problems, such as cardiovascular diseases. Some bad fats come from animal sources and certain types of oils. Trans-fat can cause the cell-membrane to become more rigid and arteries become more stiff. The "bad" LDL-cholesterol goes up and the "good" LDL-cholesterol goes down. However, we do need a some unhealthy fats in our bodies. In conclusion, fats can be healthy and unhealthy for your body, so control the amount you take in and make a wise decision before you eat something!

Contrary to popular belief, not all fats are bad for you. In fact, most, if not all, have some benefit to the human body when consumed in moderation. Many parts of the body, such as cell membranes, hormones, retinas, joints, and nerves, use fats.
ReplyDeleteMost monounsaturated fats, of which olive oil is an example, increase the amount of "good" HDL-cholesterol and lowers the amount of "bad" LDL-cholesterol in your body. It also contains a lot of vitamins and antioxidants that are beneficial to your body. Polyunsaturated fats such as sunflower oil also increase HDL-cholesterol production. Essential fatty acids, mainly omega-6 and omega-3, are vital to cell membranes, hormones, and immunity. Omega-3 in particular has been found to aid brain and eye development as well as lower the rate of many types of bodily degeneration.
Saturated fats, on the other hand, are generally regarded as "bad" fats. However, they are needed for the production of cholesterol, though in high quantities they can be very harmful to the cardiovascular system and even kill. A type of fats that can be considered in between good and bad are hydrogenated fats. These are found in margarine, but in the process of hydrogenation required to create these fats, where hydrogen is added to further saturate polyunsaturated fats, the infamous trans fats were created as well. These fats are certainly bad, causing cell membranes and arteries to stiffen while increasing the amount of "bad" LDL-cholesterol and decreasing the amount of "good" HDL-cholesterol.
In conclusion, our bodies need fats, whether they are good or bad. Good fats such as olive oil, sunflower oil, and omega-3 are vital to our body's health. Even those fats generally known as "bad" fats are needed for some purpose. Basically, all fats are good for the human body -- as long as they are consumed in moderation.
There are three kinds of fats, the good, the bad, and the ugly. They are important in biological structures and operations. They also can keep the body warm. Good fats such as omega 3 and omega 6 can be consumed by eating fish and supplements. Other good fats are polyunsaturated and monounsaturated. Bad fats are, saturated and transfat, which can harm the cardiovascular system. Although fats can be good, they should also be limited.
ReplyDeleteThough fat is considered revolting to have at most times (which is still considered with excess amounts) it is one of the most needed materials to substain a healthy balanced diet. According to the article, monounsaturated fats such as olive oil and nuts reduce the amount of LDL cholesterol in the body. The writer also mentioned the Italians for their monounsaturated fats. So though what the Europeans may eat richer foods than Americans may, they eat less of it and at longer intervals.Polyunsaturated fats seem to do the same as the monounsaturated fats do--increase HDL while decreasing the LDL cholesterol. It is important to keep the omega 6,3 ratio near 1:1 by exercising, keeping the diet low, and having minimal cholesterol intake at all times (says the reporter).
ReplyDeleteWhy are fats important? Why are fats good, what is bad about fats?
ReplyDeleteFats are important because they are fundamental in biological structures and functions and performs many serious metabolic tasks. Cell membranes, hormones, retina, joints, nerves, etc need fat.The good fats have positive effects on our health. For example, monounsaturated fat lowers bad LDL-cholestrerol and raises good HDL-cholesterol, polyunsaturated fats are healthy oils with cardioprotective elevation of good HDL-cholesterol, essential fatty acids such as fish oil remove unwanted toxins and heavy metals.
Bad fats harm our health, however, we need some of them to keep our body functioning. Such as saturated animal fat, they wreak havoc on the cardiovascular system, but we need them for many metabolic processes.
The balance of good fats and bad fats is important to maintain one's health. Too much fat will turn against your health, but not enough fat will harm your health as well.
