단백질보충제 Whether you’re an athlete or just looking to add more nutrients to your diet, protein is one of the most important macronutrients. It supports healthy muscle growth, immune health and bone strength — among other things.
You should get 10% to 35% of your total calories from protein sources. But determining how much you need depends on factors like your age, weight, activity level and goals.
What is Protein?
Protein is a group of amino acids that help build and repair tissues in the body. It’s found throughout your body in muscles, bones, organs, and other body parts or tissue, and makes up the enzymes that power many chemical reactions as well as hemoglobin that carries oxygen in your blood.
There are more than 10,000 different proteins in your body, and they all do important jobs to keep you healthy. Some of these are able to be made by your body, while others need to be found in the foods you eat.
Complete proteins (like those found in meat, dairy and whey) contain all the essential amino acids your body needs to maintain good health. Incomplete proteins (like most plant foods) may not have all the amino acids your body needs, so you’ll need to combine them with other proteins in your diet to get enough of the essential ones.
In general, the National Academy of Medicine recommends between 10-35% of your total daily calories come from protein sources. This includes eating a serving of some 단백질보충제 type of meat, poultry or fish each day, plus a small amount of dairy such as milk, yogurt or cheese.
You can also get protein in a variety of other foods, including nuts and seeds. Almonds, pistachios, cashews and walnuts all contain almost 6 grams of protein per one-ounce serving. Hemp seeds, sunflower seeds and squash and pumpkin seeds are all good choices too.
For those who are trying to lose weight, a Harvard study suggested that increasing the amount of protein in your diet could help with that goal, but only if you also cut back on other types of calories and fats. Similarly, those on low-carb or ketogenic diets may be able to lower their risk for certain diseases and premature death by consuming more protein.
But the best way to find out how much protein you need is to speak with a nutritionist or a dietitian. They can guide you through the process of figuring out your own personal calorie target and determine the right amount of protein for you.
How Much Protein Do I Need?
Protein is one of the most important macronutrients, meaning it helps to keep our bodies functioning well and can help support weight loss. It’s also the most filling nutrient, which can make it easier to maintain a healthy weight and feel full.
The amount of protein you need is determined by several factors, including your age, activity level and health condition. The current recommended dietary allowance (RDA) is 0.36 grams of protein per pound of body weight, or 0.8 grams of protein per kilogram of body weight. However, this is only the minimum to prevent a protein deficiency (4) and most active adults, older people, and those who are pregnant or breastfeeding need much more.
In general, the Institute of Medicine recommends that 10% to 35% of your daily calories come from protein. That can include a variety of foods, including meats, poultry, fish, dairy products, eggs and some non-dairy sources like beans, nuts and seeds.
It’s important to get protein from a variety of food sources so you are getting the complete range of amino acids that your body needs. The amino acids are the building blocks of proteins and they form a variety of chemicals in your body, such as enzymes, hormones and proteins.
Most people can easily meet their daily protein needs by eating a variety of foods that contain 15-30 grams of protein each day. Examples of protein-rich foods include beans, lentils, peas, tofu, tempeh, edamame, nuts and seeds and their butters, eggs, milk and cheese.
For example, a banana, a hard-boiled egg and a glass of Greek yogurt each have 19 grams of protein, while a 3-ounce chicken breast with a half-cup of rice and a half-cup of vegetables has 25 grams.
Many other plant foods, such as vegetables, grains, fruits, nuts and seeds, can be great protein sources. But these foods often have lower protein levels than meats and poultry, so it’s essential to choose them carefully.
In addition to providing protein, these plant-based sources of nutrition are high in fiber and vitamins and minerals, including iron, vitamin B12, calcium and zinc. They are also low in saturated fat, sodium and added sugars, so they can contribute to a well-rounded diet.
Protein Sources
Protein is a key macronutrient that helps promote health and strength, as well as keeping you feeling full. You can get plenty of protein in your diet by eating a wide range of foods, including meat, poultry, seafood, beans, peas, lentils, eggs, nuts, seeds, and soy products.
Most people get enough protein if they consume 10 to 35 percent of their calories from protein. That’s the amount recommended by the United States Department of Agriculture (USDA).
Many protein-rich foods, such as skinless chicken and turkey, fish, nut butters, beans, legumes, and lentils, contain only healthy unsaturated fats, which can help you avoid heart disease. They also have other nutrients that are important for maintaining your health and body.
Animal proteins, such as meat and milk, are the most common sources of protein consumed by Americans. These foods are high in essential amino acids and have been shown to increase muscle mass, decrease body fat, and improve cholesterol levels.
However, many health professionals worry about the saturated fat that is commonly found in these foods. Saturated fat is associated with heart disease and stroke risk, so it’s best to choose lean meats and poultry over red meat and processed meat.
Plant-based protein sources are becoming more and more popular, such as lentils, beans, and nuts. These proteins are high in fiber, vitamins, and minerals. They are low in fat, so they can help you lose weight while getting enough protein.
Despite the growing popularity of vegetarian diets, many individuals still struggle to meet their daily protein requirements. Some health professionals recommend consuming at least 7 grams of protein per 20 pounds of body weight to ensure adequate nutrition.
The quality of protein is assessed by a variety of methods, including the percentage of essential amino acids and the amount of digestible protein. Some of these measurements include biological value, net protein utilization, PDCAAS (Protein Digestibility Corrected Amino Acids Score), and the protein efficiency ratio.
The most important thing to remember is that your diet should provide enough protein for you to feel healthy and strong, without causing you to gain excess weight. It is especially important to make sure that you are consuming a healthy balance of proteins and carbohydrates.
Protein Supplements
Protein supplements are a convenient way to increase your protein intake. They come in many forms, including powders, shakes, bars, and cereals. They are usually a good source of high-quality proteins that contain essential amino acids.
Protein is an essential nutrient that your body uses to build and repair tissue. It also helps you burn fat. It is important to make sure you are getting enough protein every day. The amount of protein you need depends on several factors, including your biology, lifestyle, and goals.
Athletes, weight lifters, older adults, and people with a chronic illness may need to exceed the general protein intake recommendation. Typically, the recommended daily protein intake is 0.8 grams per kilogram of body weight (or 1.1-1.9 g/kg for someone weighing 175 lbs).
Some people choose to add protein powder to their meals. They can mix it with water, cow’s milk, plant-based milk, or fruit and vegetable smoothies. Others take it before or after exercise, depending on the directions on the package.
Whey protein is a common type of protein supplement because it is fast-absorbing and contains all of the amino acids the body needs. It is popular among athletes because it can boost muscle growth and strength. It is also a good choice for vegetarians and those with dairy allergies.
Casein is another common protein supplement because it is rich in glutamine, which can speed up muscle recovery after exercise. It is also low in calories and filling. This type of protein is not suitable for vegans or those with lactose intolerance.
Hemp is an excellent plant-based protein, which is high in essential amino acids and fatty acids. It’s also gluten-free and non-allergenic.
There are many different types of protein powders, and they vary in price and quality. It is important to choose a reputable brand that offers a certificate of analysis.
While protein powders are a great way to increase your protein intake, you should also check the labels for heavy metals and chemicals. A recent study by the Clean Label Project found that many of the best-selling protein powders contained lead and BPA.
