In one sentence, describe what the following article is about: Keratin is found naturally in vegetables like kale, broccoli, onions, leeks, and garlic. Include these foods in your meals to boost your body's keratin naturally. Liver, fish, yogurt, and low-fat milk are other good food sources of keratin. Include healthy proteins in your diet to help your body make more keratin. Eat lean meats, poultry, fish, eggs, and low-fat dairy. Remember that red meat is high in fat, so be sure to balance your other health needs with your keratin-friendly diet. If you're vegetarian or vegan, snack on high-protein products like walnuts, almonds, and beans. Include fatty fish in your meals several times a week. Salmon, mackerel, herring, trout, sardines, and tuna are good sources of omega-3 fatty acids that can help your body make keratin. Limit salmon and canned tuna to 12 oz. per week. Don't eat mackerel if you're pregnant it's considered a high-mercury fish that's best avoided during pregnancy. Your body needs vitamin C to make keratin. Include plenty of fresh fruits and vegetables in your diet, as these are high in vitamin C. Some of the best produce for vitamin C include: Citrus fruit and juice, like orange and grapefruit Tropical fruits like cantaloupe, kiwi, mango, papaya, and pineapple Strawberries, blueberries, blackberries, raspberries, cranberries, and watermelon Broccoli, cauliflower, and Brussels sprouts Peppers (green and red), tomatoes, and potatoes (sweet and white) Leafy greens like cabbage, spinach, and turnip greens Your body needs biotin to make healthy hair and skin, partly due to its role in keratin production. Upping your intake of biotin-rich foods may improve hair and nail quality, though not much research has been done on this. Get biotin from foods like: Eggs (with the yolk) Vegetables like cauliflower, beans, blackeyed peas, soybeans, and mushrooms Whole grains Bananas Nuts like almonds, peanuts, walnuts, pecans, peanuts and their nut butters Cystine is turned into a building block of keratin in your body. Include foods rich in cystine in meals regularly. Eggs are one of the best sources of cystine. Other good food options are beef, pork, seeds, and milk. Choose lean and low-fat options, which are better for your heart and overall health.
Summary: Eat foods that contain keratin. Consume a protein-rich diet. Eat omega-3 fatty acids. Up your vitamin C intake. Eat foods rich in biotin. Get cystine from your diet.

In one sentence, describe what the following article is about: The singer should be a trained vocalist, as power metal music can be extremely vocally demanding. Many Power Metal vocalists choose to sing in a high vocal register, but this is not a necessity. Lyrics are generally high fantasy themed, featuring references to Elves, Dragons, Lord of the Rings, and other fantastical elements, though your songs should be about whatever you want them to be about. Many bands choose to tell fantastical, epic stories through their music. Mastodon even recorded a concept album about Moby Dick. A common element of most power metal songs is the fast, intense instrumentation. This makes power metal parts particularly difficult to play, so start by writing them and practicing at a comfortable speed and gradually speeding up as you learn the parts. You will probably find yourself writing songs between 150 and 200 bpm, so you will need a drummer who can keep up. In particular, power metal drumming is important in dictating the rhythmic drive of the music. You will want a drummer who can keep good time, hopefully with two bass drums and double kick pedals, and to use these quite frequently. The rhythm guitar is the backbone of power metal music, playing the chord progressions that compose the "meat" of the song. Playing a power chord, then picking the root note palm muted is a very common rhythm guitar technique in power metal. However, power chords don't necessarily have to be built off of the root note of a chord. For example, in pre-choruses, going up or down a third can sound very epic, and builds up nicely to the chorus being on the root note. Key changes can sometimes be found in the final choruses of some songs, where the main progression is moved up a tone. Minor and harmonic minor scales are great to use, while some modes, such as phrygian and dorian can also be useful. Guitar harmonies are very common as well, with third and octave harmonies being the most common. Quartal (fourth) harmonies are not as common. Sweep picking, tapping and fast alternate picking are commonly used for solos, but don't think you can just play fast and people will enjoy it! In good solos, bends add an extra degree of emotion when used properly.
Summary:
Write epic lyrics and sing them well. Gradually increase the speed at which you practice the song. Have chugging rhythm guitars. Have fast, shredding lead guitar licks.
