Article: Your body needs protein to heal and regenerate damaged or old tissues. Two to three servings of protein rich foods per day should be plenty for the average adult.  1 ounce of meat counts as equivalent to one ounce of protein, but so does a single egg, 1/4 cup of cooked beans, and 1 tablespoon of peanut butter.  From age 19 to 30, women should eat 5 1/2 ounce-equivalents of protein per day, while women over age 30 should eat 5 ounce- equivalents of protein per day. Men age 19 to 30 should consume 6 1/2 ounce-equivalents of protein per day; from 31 to 50, men should eat 6 ounce-equivalents, and over 50, you should eat 5 1/2 ounce-equivalents of protein per day. Carbohydrates provide energy for you to get out and move. You should be getting about half of your calories from carbohydrates. Try to choose unprocessed, whole grains over processed carbohydrates. For instance, eat whole-grain pasta, whole-wheat bread, oatmeal, fruits, and vegetables over foods such as white bread, soda, fruit juice, or desserts. Whole grains have more fiber and keep you fuller for longer, as it takes your body longer to process. A healthy diet with fruits and vegetables will provide you with the nutrients you need for an active, on-the-go lifestyle. Try to eat the rainbow, meaning you should vary the color of your fruits and vegetables, as they all have different nutrients. For instance, greens are high in vitamin K, which can help reduce bruising, while red vegetables, such as tomatoes, are high in lycopene, which can help protect your skin from the sun.  On a 2,000 calorie diet, you should eat 2 cups of fruit and 2 1/2 cups of vegetables a day.  Fruits and vegetables are low in calories and fat, but high in fiber and vitamins. This healthy eating pattern will reduce your risk for getting cancer, heart problems, high blood pressure, strokes, and diabetes. As you get older, your metabolism slows down and you want to be careful not to gain too much weight. You should keep your daily intake of fat under 65 grams.  Try to pick healthy fats over unhealthy fats. Unhealthy fats include saturated fats (mainly in fatty beef, chicken with the skin still on, and full-fat dairy) and trans fats (mainly in hydrogenated oils and processed foods).  Healthier fats include monounsaturated fats (in olive oil, sesame oil, peanut oil, peanut butter, and avocado, to name a few), polyunsaturated fats (in many plant-based oils), and omega-3 fatty acids (mainly in fish).  Eating too much fat increases your chances of high cholesterol, heart problems, and strokes. You can reduce your fat consumption by eating lean meats, poultry, fish, and choosing low-fat dairy products. Reducing salt will help you avoid high blood pressure and reduce your chances of heart, liver and kidney conditions. While you need some salt to stay healthy, too much is not good.  Adults should consume no more than about a teaspoon of salt per day, which is about 2,300 milligrams of salt per day. If you have a health condition, such as high blood pressure, you need to keep your intake under 1,500 milligrams per day.  Read labels, as many products have more salt than you would think. Often, processed foods, such as canned vegetables, lunch meats, frozen foods, and pickles, are high in salt.

Problem: Article: People who feel uncomfortable about their height may be prone to  slouching. This not only looks bad, but it can cause back pain. For the best posture, keep your shoulders comfortably back. They should never be raised towards your ears or rounded forward. Be careful not to hyper-correct. Your shoulders should not be so far back that you would not be able to stand with your entire upper back against a wall. Just like slouched shoulders, walking with your head down makes you look like you are not confident, and it can cause you pain. Try to hold your head up straight so that your neck is not bending forward or to either side. You should be looking directly in front on you, not at your feet! A good way to tell if your head is straight is to take notice of your chin. It should be parallel to the floor for ideal posture. You should have a slight arch in your lower spine. To find out if your posture is proper, stand against a wall so that your head, shoulders, and bottom touch the wall and your feet are a few inches away. If you can just barely slip your flat hand behind your lower back, your posture is ideal. If you have too much or too little of an arch, make a conscious effort to correct it. Pulling your abdominal muscles in can help straighten your back. While arm and leg posture is not directly related to your height, they are essential to overall good posture. Having your arms and legs in the correct position while walking will make you look much more confident.  Your arms should hang freely by your sides as you walk. Your legs should be about the same distance apart as your hips, and you should distribute your weight evenly on both feet. Be careful not to lock your knees.
Summary: Keep your shoulders back. Hold your head high. Maintain the arch in your lower spine. Remember your arms and legs.

For jewelry decorated with porous gems, watches, antiques that have pieces held with glue, or other delicate silver pieces that can’t be immersed in water or cleaned with the electrolysis method, there are still several options for cleaning.  Mix one tablespoon (15 ml) dishwashing soap (something that’s phosphate-free and ammonia-free) with one cup (240 ml) warm water and stir well. If you want, use a hand blender to mix up some suds. Dip a soft cloth into the soapy water and wring out the excess. Use the damp cloth to clean the silver. Rinse out the cloth with plain water, and wipe off any leftover soap residue. Use a fresh cloth to buff and dry the silver. Take a tablespoon (15 g) of baking soda and mix it with just enough water to make a paste. With a soft-bristled toothbrush or cloth, clean the silver with the paste, making sure to get into the nooks and crannies with the bristles. When the silver is clean, rinse it under warm water or remove the excess paste with a damp cloth. Buff it dry with a clean cloth. In a small bowl, whisk together 1 teaspoon (6 ml) lemon juice and 1.5 cups (327 ml) olive oil. Dip a cloth into the mixture, wring out the excess, and use this to polish your silver.  For small pieces that can be immersed, soak them in the oil and lemon solution and place the bowl into a small saucepan. Fill the saucepan with enough water to bring the bowl off the bottom and turn the heat to medium. Bring up the water temperature and keep it hot, but not boiling, for 15 to 20 minutes. Remove the pot from the heat and take the silver out of the oil and lemon juice solution. Gently scrub the silver with a soft toothbrush. For either the hot bath or the polishing method, rinse the silver with hot water to remove excess solution, and dry it with a soft cloth. Glass cleaners like Windex can also be used to clean silver. Spray some glass cleaner directly onto a soft cloth or soft-bristled toothbrush. Use the cloth to clean the silver, and then either rinse the piece under warm water or wipe off the excess cleaner with a damp cloth. Dry and buff the silver with a soft cloth.
