Article: To promote muscle recovery, eat right after you’ve finished running. That goes for training sessions and the big race. Go for high-carb or high-protein items, such as fruit, yogurt, whole grain bread, brown rice, legumes, poultry, and fish. Never go more than 90 minutes after a run without eating. Your muscles refuel most efficiently soon after strenuous activity. Healthy, high-carb foods should comprise about 60 to 70% of your diet. For a 2500 calorie diet, that means you should consume 1500 to 1750 calories, or about 375 to 440 grams of carbs per day. Good sources of complex carbs include fruits, veggies, beans, brown rice, and whole grain bread and pasta.  High-carb options could include a whole grain bagel with egg and cheese for breakfast, a whole grain pasta salad for lunch, pieces of fruit and nuts for snacks, and sides of brown rice and steamed veggies at dinner. Complex carbs supply your muscles with glycogen, which is a substance your body uses to store energy and deliver it to muscles. Go for lean protein sources, such as poultry, fish, and legumes. As a rule of thumb, runners require about 1.5 grams of protein per kilogram of body weight (about 0.7 grams per pound).  For example, a runner who weighs 170 pounds (77 kg) would need about 4 ounces (119 grams) of protein per day. A 6 ounce (170 g) serving of chicken breast, a  5 ounce (140 g) salmon fillet, 1 cup (172 g) of steamed soybeans, and 2 large eggs would meet that daily need. Overlooking protein requirements is a common mistake among runners. Protein is needed for muscle strength and durability. Many protein-rich foods also contain iron, and consuming too little iron leads to muscle fatigue. As a rule of thumb, try to drink about at least 8 cups (1,900 mL) of fluids per day. The exact amount you need to drink depends on a variety of factors, and your urine is the best way to gauge your hydration level. You’re hydrated if it’s light in color, and you’re dehydrated if it’s darker. During a run, aim to drink about 1 cup (240 mL) every 15 to 20 minutes. Never wait until you’re thirsty to drink; if you’re thirsty, you’re already dehydrated. To hydrate your body on race day, drink 2 cups (470 mL) of water or a sports drink 2 hours before the race's start time. An hour before the race, eat a 300-calorie, high-carb, low fat meal to boost your energy reserves.  For example, have a whole grain bagel with peanut butter and a banana or pasta with chicken and zucchini. Be sure to avoid items that might upset your stomach. If, for instance, dairy products give you trouble, steer clear of yogurt, milk, or cheese on race day.
Question: What is a summary of what this article is about?
Refuel with a healthy snack or meal within 15 minutes after a run. Maintain a diet packed with complex carbohydrates during training. Eat at least 4 to 6 ounces (110 to 170 g) of protein per day. Monitor your urine to make sure you’re staying hydrated. Consume a healthy meal and 2 cups (470 mL) of fluids before the race.

Problem: Article: Olive oil poaching is a technique best used with fish that are sturdy and flavorful, such as salmon, halibut or tuna. Choose either steaks or fillets that are about 3/4 to one inch thick for best results. The taste and texture of the final dish is better with thicker, sturdier fish than it is with very delicate fillets.  Season the fish with salt, pepper and other herbs that complement the meal you're serving. This method also works well with shrimp, prawns and other shellfish. Cooking at a low temperature will preserve the integrity of the fish. Set it out on the counter for 10 minutes or so before you cook it. Letting the fish come to room temperature will ensure that it cooks evenly and fully once you place it in the oil bath. Putting it straight into the oil from the refrigerator would cause the temperature of the oil to drop, throwing off the cooking time and affecting the taste and texture of the finished dish. Line a glass baking dish with thin slices of lemon, then arrange the fish fillets on top of the lemon slices. Pour enough olive oil over the fish to cover the fillets. Place the baking dish in the oven and poach the fish until the fillets are opaque and flake apart easily when forked. Check the fish after an hour, and return it to the oven for an additional 10 to 15 minutes if the fillets need additional time. Serve warm over a bed of rice or steamed vegetables.
Summary: Choose a flavorful fish. Preheat the oven to 250 degrees. Let the fish come to room temperature. Prepare the baking dish. Poach the fish for one hour.

Article: These are sometimes referred to as tree rings. The edging will need to be made of stone, clay, or brick and can be scalloped or straight across the top. You will need to purchase 4 pieces of 14" inside diameter bricks and 6 pieces of 24" inside diameter bricks. Clear an appropriate area for your firepit and then lay out the first two 14" pieces to form a circle. Use three of the 24" to form a larger circle around the first one. You can use a bit of concrete to help the pieces stay together, if you want. Use the remaining pieces to set out the second layer, on top of the first. You can put a layer of concrete between the two stone layers, if you want to. If you use scalloped bricks, put the second layer upside down, so the scalloped edges are touching between the two layers. Fill the gap between the circles with river rocks until the brim is reached. Alternatively, you can fill it most of the way to full and then put down a thinner layer of more aesthetically pleasing rocks, like glass pebbles. Put a small layer of river rocks or other fire-friendly material in the bottom of the pit. Alternatively, you can find a grill bowl with the same diameter (or very slightly larger) as the central circle and place it there. Set up a wood fire in the central pit and enjoy your new fire pit. Put a circular grill surface over the hole to use it as an outdoor cooking pit!
