Nutrition Back to Basics September 20, 2011 Prayer Journal “ Be very careful, then, how you live – not as unwise but as wise, make the most of every opportunity, because the days are evil. Therefore do not be foolish, but understand what the Lord’s will is.” Ephesians 5: 15 - 17 God Remakes You “But when the kindness and love of God our Savior appeared, He saved us, not because of righteous things we had done, but because of his mercy. He saved us through the washing of rebirth and renewal by the Holy Spirit.” Titus 3: 4-5 Lecto Divina Meditating on Scripture Remember to really think about this verse this week. Ask God to reveal and show you special things about it. Write down what you think He may be telling you about this verse. Heaven is for Real What do you think of this story so far? Read Heaven is For Real to page 139. “Do Hard Things” by Alex and Brett Harris C. Everett Koop, MD says… “If you do not smoke or drink excessively, your diet can influence your long-term health prospects more than any other action you might take.” Your Food Journal What did you eat that day?!? Food is Fuel 1. 2. 3. 4. 5. 6. 6 Main kinds of Nutrients Protein Carbohydrates Fats Vitamins Minerals Water All of these provide 1. 2. 3. Fuel for energy The basic building blocks for growth and maintenance Substances that act to control body processes Look at your Food Journal What kinds of food did you eat ? Did you eat at home? Any fast food? Proteins 1. 2. 3. 4. Essential part of every cell in your body The largest portion existing in the muscle tissue Only source for nitrogen, which is needed for building new tissue Amino Acids: Page 62 - 63 Amino Acid Chains Proteins are made from simpler molecules, called amino-acids. There are twenty different amino-acids that make up proteins. Each one has been given a letter, A, C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, W or Y. The amino-acids form chains to make proteins. Each different chain of amino-acids makes a different protein. Complete Proteins Contain all the amino acids come from animal proteins (meat, poultry, fish, cheese and eggs) Proteins can be obtained from vegetables, however they are incomplete. They must be combined with grains, seeds and nuts to become complete proteins. Animal proteins are not necessary for a healthy diet. Food Journal Select foods that have good sources of lean protein or combine vegetables and grains to create complete proteins. Carbohydrates 1. 2. 3. Energy producers for the body Sugars and starches Provide energy for the body Helps to control the breakdown of protein Protects the body against toxins Carbohydrates Once eaten, the body turns carbohydrates into a sugar called glucose. Glucose is fuel for the body Carbohydrates 1. 2. Made of links or strings of sugar Simple sugars called: Monosaccharides that are single molecule sugars; Complex carbohydrates: Polysaccharides composed of many monosaccharides molecules and are broken down by the body into two or more sugars. Your body stores some of these for emergencies When glucose and glycogen reserves are gone, you should eat. Otherwise your body will turn to some of your protein into glucose for energy. High Protein / no Carbohydrates diets Complete Carbohydrates Have a higher nutritional value than simple sugars They also have fiber that helps food waste move through the intestines (digestive system) Good sources of vitamins, minerals, and protein. These foods take longer to digest, so you feel full longer Examples of Complex Carbohydrates Complex carbohydrates, on the other hand, are longer chains of sugars predominantly coming from foods without such a noticeably sweet flavor, such as rice, bread, potatoes, oats, pasta, and things of that nature. Carbohydrates that create Glucose Milk, dried fruits, fruit juices, honey, candy, cookies, cakes, sweet desserts, donuts. Simple carbohydrates are shorter chains of sugars, usually coming from food items with a noticeably "sweet" flavor. Candy, fruit and sports drinks are all examples of simple sugars. Carbohydrates are long chains of sugar molecules connected together. There are basically two kinds of Carbohydrates: Simple and Complex. Simple Carbohydrates are made up of only 1 or 2 sugar molecules. Complex carbohydrates are made up of many sugar molecules linked together. Food Journal Select Foods which have a low glycemic index. Select vegetables and fruits as close to their natural state, not overly processed, fried or sugared. Review 1. Proteins are chains of Amino Acids 2. Carbohydrates are chains of glucose Fats Are chains of fatty acids: long molecules of carbon, hydrogen and oxygen. Fats 1. 2. 3. 4. 5. 6. Provide a concentrated source of energy. They can provide more than twice as much energy as carbohydrates. Fats are an essential part of the diet: Growth and repair of the body Maintaining body temperature Cushioning vital organs Insulation of the body through the stored fat in tissues Keeping the skin from becoming dry and flaky Manufacturing certain hormones Saturated Fat Increases blood cholesterol levels, which increase the risk of heart disease. The body does not need any saturated fat in its diet. It can manufacture all it needs from the other fats. Red meat, pork products, egg yolks, butter, hard margarines, most cheeses and dairy products and certain oils. Unsaturated fats Do not tend to elevate cholesterol levels. They are usually liquid at room temperature Corn, safflower, cottonseed and canola oils are examples of unsaturated fats. Frying or deep frying process changes the unsaturated fat to saturated fat. Why does this matter? Unsaturated fats and cholesterol are well known to spontaneously form harmful molecules when exposed to oxygen. This happens not just when fats and oils are heated, but also during the shelf life of food and nutritional products, and even within our bodies whenever these lipids (fats) are consumed in excess. Because fats and cholesterol (collectively belonging to a class of chemicals known as lipids) make up such a major part of our very structure, it is important for our health that we minimize both the presence of rancid, oxidized fats in our food and also the formation of oxidized fats within our body. These oxidized fats can cause: major free radical damage, weakening our immune system, interfering with proper hormone synthesis, reducing our antioxidant status, and acting as the most significant contributors to cellular degeneration by worsening the phenomenon known as oxidative stress. And even many products sold within the health food and nutritional supplement industry, especially some products which are said to contain supposedly "good fats," may in fact contain, or cause the production of, high levels of oxidized lipids. Far from being "good," many of these fats, when oxidized, or when taken in excess, are known to accelerate every conceivable mechanism of aging and disease. Cholesterol 1. 2. 3. 4. 5. Your body needs a small amount of cholesterol. The liver can manufacture all of our needs. We do not need to eat it. Make vitamin D Make hormones Build cell structure by forming cell membranes Make bile acids to help digest fats Build nerve tissue Cholesterol Is a waxy substance that is carried in the bloodstream by lipoproteins, proteins to which fats are attached. 1. Low density lipoproteins (LDL) BAD 2. High density lipoproteins (HDL) GOOD LDL is called BAD cholesterol deposits in the arteries. Higher the LDL count in the blood, greater the risk of heart disease. HDL: it forms cholesterol that is being removed from circulation and transported to the liver to be eliminated. Essential Fatty Acids Fatty acids that are required by the human body but cannot be made in sufficient quantity from other substrates, and therefore must be obtained from food, are called essential fatty acids. There are two series of essential fatty acids Two essential fatty acids are: 1. 2. linoleic acid (LA) and alpha-linolenic acid (ALA). They are widely distributed in plant oils. The human body has a limited ability to convert ALA into the longer-chain n-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which can also be obtained from fish. Choose the Right Foods The “typical” American diet consumes between 400-500 milligrams of cholesterol a day. The American Heart Association recommends 300 milligrams of cholesterol a day. Ideally, it should be around 100-200 milligrams daily. Controlling Fats does not have to be complicated…. Become informed Exercise Read food labels Eat foods that are as close to their original state and minimally processed and/or fried. Have your cholesterol checked even if you think you eat well. Food Journal Take a look at your food journal from last week. What kind of fats did you consume? Think about the food choices you made and consider other alternative foods that might be healthier. Prescription for Good Nutrition 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Eat a variety of Foods Maintain ideal weight Use exercise to keep your metabolism high Increase dietary fiber to 25-35 grams a day Eat less sugar East less sodium (salt) Eat less fat Avoid alcohol and smoking Drink plenty of water Avoid eating while under stress Your Food Journal How did you measure up? Let’s try it again now that you are informed It takes practice. It does not mean you will never have another bite of “forbidden” food. Choose healthy snacks and meals. Read labels. Hopefully, you will enjoy a small amount of all of your favorites! You might even discover a “new favorite!” Homework Total Health: Read to Page 91 Answer questions: 4, 6 – 10.
