Protein And Food Allergies: What To Know

Why do you need to eat protein?

Food allergies occur when the bodys immune system attacks certain food proteins. Your body will fight back by making its own proteins, called IgE antibodies, or immunoglobulin E. If you have an allergy to a certain protein, the next time you eat or drink something containing that protein, youll experience an allergic reaction, such as itchiness or trouble breathing.

Many of the most common food allergies are associated with foods that are high in protein, such as eggs, peanuts, tree nuts, and fish.

Protein Bars Are Really Just Candy Bars With A Bit Of Extra Protein

Indeed, research on the muscle-building power of protein supplements is varied. A 2014 analysis of 36 papers found that protein supplements have no impact on lean mass and muscle strength during the first few weeks of resistance training in untrained individuals.

Over time and if the training becomes harder, supplements can promote muscle growth. However, the paper also concludes that these changes have not been proven over the long term. A 2012 review paper further says that protein increases physical performance, training recovery and lean body mass but for the benefit to be optimal, it should be in combination with a fast-acting carbohydrate.

But even if athletes and gym goers may benefit from a post-workout protein boost, that doesnt mean they should reach for the supplements and smoothies. Most people get more than their daily recommended allowance from food, says Kevin Tipton, a sport professor of the University of Stirling. Theres no need for anyone to have supplements. Theyre a convenient way to get protein, but theres nothing in supplements you cant get in food. Protein bars are really just candy bars with a bit of extra protein.

The global protein supplements market was valued at $12.4bn in 2016

How Much Protein Should You Consume And How Often

So now that weve covered the many benefits of protein, lets talk about how much you need, especially if youre using it to supplement your workouts.

If youre a moderately active adult, I recommend between 0.5 0.75 grams of protein per pound of body weight. If youre regularly doing resistance training, youll want between 0.8 0.85 grams of protein per pound of body weight. Eating more than 1 gram of protein per pound of body weight has not shown to have any additional benefit.

Timing of protein intake is especially important for athletes or anyone trying to build muscle. Exercise, especially resistance training, stresses the muscles. Eating protein after a workout helps repair the muscle breakdown that has occurred and further builds upon that muscle.

You should aim to consume at least 20 grams of protein within a half-hour after exercising. Choose high-quality proteins after training and at mealtimes.

Why Is Vegan Protein Powder Good For You

You may be able to get even more nutrition from vegan protein powders than from regular whey protein. Vegan options, in addition to providing clean alternatives to whey, can also help with digestion. They may be a better digestive aid than whey protein and may also improve your cardiovascular health.

What Exactly Is Protein

Think of protein as strings of sausages. Long strings some many thousands. Each sausage represents one of 15 similar small molecules called amino acids. The order of amino acids in the chain is programmed by DNA. Amino means that they contain nitrogen, but they also contain carbon, hydrogen and oxygen atoms. In order to do their jobs, proteins curl up into characteristic shapes, and many of them need to incorporate minerals or vitamins in order to function.

Some proteins are solid, some are flexible in cell membranes, others are mobile in solutions

What Is Protein And Why Do I Need It

Protein is considered the building block of life and is found in every cell of the body.

Protein is made up of amino acids that are attached to one another in long chains. There are 20 different kinds of amino acids, and the sequence in which the different amino acids are arranged helps determine the role of that particular protein.

Proteins play a role in:

  • Transporting molecules throughout the body
  • Helping repair cells and make new ones
  • Protecting the body from viruses and bacteria
  • Promoting proper growth and development in children, teenagers, and pregnant women

Without filling your diet with appropriate amounts of protein, you run the risk of missing out on those key functions. Eventually, that could lead to problems, such as a loss of muscle mass, failure to grow, weakened functioning of the heart and lungs, and even early death.

More About Protein Residue Testing

Protein residue testing is a method used to measure levels of Infection Control in cleaning processes. With effective testing for proteins, you can locate potential issues with processes such as:

  • Complexity of instrument, loading patterns
  • Washer disinfector defects
  • Human error issues in the manual cleaning processes
  • Pathway of set: Wet/dry time from surgery

As the PRO1 MICRO offers quantitative data, you can also witness a trend should your testing results show a steady increase in µg. Meaning you can prevent possible issues before they occur or progress to a larger scale concern.

Protein: Is More Better

For a relatively active adult, a daily protein intake to meet the RDA would supply as little as 10% of his or her total daily calories. In comparison, the average American consumes around 16% of his or her daily calories in the form of protein, from both plant and animal sources.

The Protein Summit reports in AJCN argue that 16% is anything but excessive. In fact, the reports suggest that Americans may eat too little protein, not too much. The potential benefits of higher daily protein intake, these researchers argue, include preserving muscle strength despite aging and maintaining a lean, fat-burning physique. Some studies described in the summit reports suggest that protein is more effective if you space it out over the days meals and snacks, rather than loading up at dinner like many Americans do.

Based on the totality of the research presented at the summit, Rodriguez estimates that taking in up to twice the RDA of protein “is a safe and good range to aim for.” This equates roughly to 15% to 25% of total daily calories, although it could be above or below this range depending on your age, sex, and activity level.

However, over the last several years, the public health message has shifted away from desired percentages of protein, fats and carbohydrates. For example, the current Dietary Guidelines for Americans emphasize the importance of eating healthier protein rich foods rather than concentrating on specific amounts of daily protein.

How To Spot The Signs Of 7 Common Nutrient Deficiencies

Why YOU Should Use Protein Powder (if you arent already)

Word to the wise: Study the nutrition label before digging into protein shakes and other supplements. Just because a product is high in protein doesnt necessarily make it healthy all around. Look for protein supplements that are no more than 200 calories, have fewer than 2 g of saturated fat, and no more than 5 g of sugar.

Also, because supplements arent regulated by the Food and Drug Administration , theres no oversight checking to make sure the products live up to the claims on their packaging, so take these with a grain of salt and be sure to talk to your healthcare team before adding them to your diet.

Experts say its a good idea to lean on whole foods rather than processed foods to source your protein, as whole foods offer nutritional benefits that the man-made options dont provide.

Protein Maintaining Muscle Mass As You Age

From around 50 years of age, humans begin to gradually lose skeletal muscle. This is known as sarcopenia and is common in older people. Loss of muscle mass is worsened by chronic illness, poor diet and inactivity.

Meeting the daily recommended protein intake may help you maintain muscle mass and strength. This is important for maintaining your ability to walk and reducing your risk of injury from falls.

To maintain muscle mass, its important for older people to eat protein effectively. This means consuming high-quality protein foods, such as lean meats.

Youve Got Achy Joints

In the previous post about fat requirements, I explained how my first response to achy joints is to increase my omega-3 consumption because that quickly curtails inflammation. But if that doesnt work and even if it does I then turn to gelatin. Gelatin is connective tissue its made of the stuff we use to repair and build our own cartilage, tendons, ligaments, and fascia. A few studies indicate that eating gelatin can improve joint pain:

A novel collagen type II supplement improved pain, range of motion, and stiffness in women with severe joint pain and patients with rheumatoid arthritis.

Getting More Protein Into Your Day Naturally

If youre looking for ways to get more protein into your diet, here are some suggestions:

  • Try a peanut butter sandwich. Remember to use natural peanut butter with no added salt, sugar or other fillers.
  • Low-fat cottage or ricotta cheese is high in protein and can go in your scrambled eggs, casserole, mashed potato or pasta dish. Or spread it on your toast in the morning.
  • Nuts and seeds are fantastic in salads, with vegetables and served on top of curries. Try toasting some pine nuts or flaked almonds and putting them in your green salad.
  • Beans are great in soups, casseroles, and pasta sauces. Try tipping a drained can of cannellini beans into your favourite vegetable soup recipe or casserole.
  • A plate of hummus and freshly cut vegetable sticks as a snack or hummus spread on your sandwich will give you easy extra protein at lunchtime.
  • Greek yoghurt is a protein rich food that you can use throughout the day. Add some on your favourite breakfast cereal, put a spoonful on top of a bowl of pumpkin soup or serve it as dessert with some fresh fruit.
  • Eggs are a versatile and easy option that can be enjoyed on their own or mixed in a variety of dishes.

How Much Protein Do We Need

Why Do I Need Protein?

The truth is, you dont need that much protein for your body to function properly. In order for your body to support its basic needs, you need 0.8 g of protein per kilogram of body weight. Hang on to your calculator! Stats suggest that most people easily achieve this target, and in fact, the average adult consumes about 90 grams of protein per day.

The recommended dietary allowance, or RDA, of 0.8 g per kilogram may be a low bar, says Douglas Paddon-Jones, PhD, FACSM, Sheridan Lorenz Distinguished Professor in Aging and Health, Department of Nutrition and Metabolism, The University of Texas Medical Branch. To offset some of the muscle decline that occurs as we age and to get the feel-full benefits, he recommends more. However, whats just as important is how youre spreading out your protein throughout the day and ensuring youre making smart protein picks.

The Scoop On Protein Powder

Eating enough protein is not just for athletes or would-be Schwarzenegger types. It is necessary for a healthy immune system and required for organs like your heart, brain, and skin to function properly. The nutrient is also touted for its ability to help control appetite and enhance muscle growth.

How much protein you need typically depends on your exercise routine, age, and health. And whether to supplement protein intake with a protein powder has become a common query.

Why Do We Need Proteins

Your body needs protein to stay healthy and work the way it should. More than 10,000 types are found in everything from your organs to your muscles and tissues to your bones, skin, and hair. Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood.

Benefit #3 Protein Helps Maintain Your Muscles

Since protein is the building block of your muscles, eating adequate amounts of protein helps maintain your muscle mass and prevents muscle wasting. So if you walk a lot, enjoy cycling, or do any sort of exercise to stay active, you need to eat protein.

Athletes and individuals with more muscle need to eat larger amounts of protein daily to maintain their higher muscle mass.

Are You Getting Too Much Protein

Med Talk, Health Talk: Protein – Why we need it

Judging by all the protein bars, shakes and powders out there, you get the impression you need more protein. There are claims it curbs appetite, helps with weight loss and builds muscle. But whats the real story?

Contrary to all the hype that everyone needs more protein, most Americans get twice as much as they need. This is especially true for males 14-70 years of age, who the 2015 Dietary Guidelines for Americans advise to decrease meat, poultry and egg consumption. Even athletes are often getting more protein than they need, without supplements, because their calorie requirements are higher, and with more food, comes more protein.

True or False: Big steak = bigger muscles

False. Although adequate protein throughout the day is necessary, extra strength training is what leads to muscle growth, not extra protein intake. You cant build muscle without the exercise to go with it.

The body cant store protein, so once needs are met, any extra is used for energy or stored as fat. Excess calories from any source will be stored as fat in the body.

Extra protein intake can also lead to elevated blood lipids and heart disease, because many high-protein foods you eat are high in total fat and saturated fat. Extra protein intake, which can be taxing on the kidneys, poses an additional risk to individuals pre-disposed to kidney disease.

Why Do Athletes Need Protein

Protein is an essential nutrient in the diet and getting enough protein is important for everyone especially athletes. But why does it play such a key role? Here, we give you all the need-to-knows on this essential nutrient, discussing its importance for the body, athletic performance and practical ways to achieve protein targets

What does protein do?

Protein makes up the structure of cells and tissues in the body, including muscle tissue. Although the majority of energy comes from carbohydrates and fat during exercise, protein may also contribute to fuelling exercise.

Why is protein important for the body?

Protein is needed for the growth and formation of new tissue, and it also helps to repair any muscle fibres that may have been damaged through exercise. As well as this, protein plays a role in making various enzymes and hormones – such as adrenaline whilst also maintaining fluid balances in tissue when transporting important nutrients around the body and regulating blood clotting.

How does protein intake impact performance and recovery?

It is well researched that consuming protein after exercises increases post-training adaptation and can help to enhance performance for both strength and endurance exercise. However, how much protein you consume in a serving is an ongoing debate in research. Most believe that 0.25g per kilogram of body weight or 20g-40g of protein should be consumed at each meal or snack.

Protein And Bone Health

It has been suggested that high protein intakes could be detrimental for bone health by causing demineralisation due to increased urinary calcium excretion. This has not been demonstrated by RCTs though several systematic reviews note that the quality of evidence in this arena is low. A systematic review performed by the National Osteoporosis Foundation in 2017 reported that most observational studies support a positive association between protein consumption and bone health, one study that found a negative relationship could be explained by simultaneous low calcium intakes. A 2012 systematic review and meta-analysis including five studies found no difference in bone mineral density between lower protein diets and high protein diets providing up to 1.6g/kg bodyweight. There are health claims approved for use in the EU which state that protein contributes to the maintenance of normal bones and is needed for normal growth and development of bone in children.

Symptoms Of Protein Deficiency And Health Risks Of Not Getting Enough

Protein deficiency occurs when you dont eat enough protein. The most severe cases result in a form of malnutrition called kwashiorkor. Usually, this affects people in very poor countries that dont have enough food to sufficiently feed the people. It rarely occurs in the United States, and when it does, its usually linked to some kind of abuse.

Symptoms of protein deficiency include:

  • Delayed growth

So Does It Matter If You Get Your Protein From Powder Or From Food

Why Do I Need Protein?

Whether or not you need protein powder really depends on what your diet consists of already, Gonzalez says. Most people can indeed get enough protein, powder-free. For the average healthy person whos pretty athletic and eating a balanced, diverse diet, theyre probably getting enough protein from their food already, Beth Kitchin, Ph.D., R.D.N., assistant professor in the UAB Department of Nutrition Sciences, tells SELF.

It is absolutely possible to consume adequate protein from real food, adds Linsenmeyer. Meat, fish, poultry, eggs, dairy, beans, lentils, soy products, nuts, seeds, whole grains all provide dietary protein.

Real food also has a couple advantages over powder. It can certainly cost less, given some protein powders can cost you a pretty penny.

The main benefit is what you automatically get alongside the protein. The plus with foods is that you are able to consume a variety of other micronutrients and fiber from a full meal, Yasi Ansari, M.S., R.D., C.S.S.D., National Media Spokesperson for the Academy of Nutrition and Dietetics and Assistant Director of Performance Nutrition for UC Berkeley Athletics, tells SELF. This is especially important if youre drinking a high-protein, low-everything-else shake to replace a well-rounded meal that would normally fuel your body with carbs and fat along with that protein. I have found people will rely more on these shakes, rather than taking the time to prepare and meal plan for a balanced diet, Ansari says.
