All Protein Powders Are The Same

When it comes to protein, there’s a bewildering array available. For the sake of convenience, you may be tempted to grab the first one you see, assuming that they’re all protein, so they all work the same way.

This is completely incorrect. Protein powders are an important supplement for those who are serious about weightlifting; you should do some research to ensure you get optimal benefits. The right sort of protein powder at certain times can ensure your muscles are fed overnight, enhance your gains, minimize your recovery time and improve your stamina.

Here is a quick overview of the main types of protein powders:

  • Whey

A by-product of the cheese-making process, whey is by far the most common type of protein supplement. It’s digested rapidly, meaning it’s ideal for feeding your muscles after a workout. Studies have shown that as well as promoting the development of lean muscle, whey also keeps your cardiovascular system healthy and supports your metabolism.

  • Casein

Casein offers the same benefits as whey protein, but is digested slowly, meaning it’s ideal to consume before you go to bed to keep your muscles fed overnight.

  • Weight Gainer

These are ideal for bodybuilders, athletes and anyone who wishes to increase their body weight. Weight gainer supplements contain whey protein combined with various high-carbohydrate ingredients. These are very calorie-dense and can help pack on the pounds when combined with the right diet and exercise.

  • Soy

Soy contains the complete range of essential amino acids, making it an ideal supplement.

  • Egg

Another source of complete protein, this supplement is based on dehydrated egg whites. Egg protein also contain a range of other beneficial nutrients.

  • Pea

A Meal Shouldn’t Contain More Than 30 Grams Of Protein

There has been a misconception for many years that the human body cannot process more than 30 grams of protein in one meal, and any extra will be stored as fat. This is simply incorrect.

The rate at which protein is used within the body depends on many factors. Other levels of nutrients in the meal such as carbohydrates and fat content, your body mass, activity levels, and whether you have recently undertaken a strenuous training session can all affect protein absorption rates, meaning some individuals require more than others for maximum health.

For bodybuilders and those involved in regular, strenuous physical activities, the optimal amount of protein needed per day can be calculated using body weight; you should be aiming to consume between 1.4 – 1.8 grams of protein for every kilogram of body weight. This amount ensures maximum protein synthesis for those involved in heavy training.

A High-Protein Diet Leads To Osteoporosis

This theory is based on the belief that a high-protein diet causes increased levels of acid within your body which leaches calcium from your bones, causing a loss of bone density.

Lean meat, dairy products and eggs are excellent sources of high-quality complete protein. However, it’s possible to get all the protein you need by combining a healthy mix of incomplete proteins, provided by certain vegetables, legumes, grains and nuts.

By planning your meals with a little care and ensuring incomplete proteins are paired, you can easily fulfill your protein requirements with a mix of non-meat foods.

High-Protein Diets Cause Kidney Problems

High-Protein Diets Cause Kidney Problems

This is another long-standing misconception that’s also completely false. It’s said that this happens as the kidneys are put under strain, filtering out excess nitrogen by-products from protein.

It is true that your kidneys will work a little harder on a high-protein diet, and low-protein diets are advised for those with kidney disease and other issues.

However, research has shown that high-protein does not cause problems in healthy individuals, as their kidneys are able to cope with the slightly increased workload.
