- I want to lose weight and a friend of mine has recommended me to buy protein.
- I have started exercising so I have bought protein.
So, when should we buy protein?
First of all, when you have found out that you do not have a sufficient protein intake from your common daily meals. Recommendations about the necessary daily protein intake differ. Let´s round it off to 1g proteins per one kilo of bodyweight for an adult. This means that if you are a woman who weighs 60 kg your daily intake should be about 60g proteins. It is natural that men or people who do more sport need more proteins, so the daily protein intake differs and it is often above 2g per one kilo of bodyweight, which I don´t recommend though. (Unless you are a body-builder on a hardcore diet). However, I understand that if you are an ordinary person who is only just finding out things about nutrition, you have no idea how many proteins you might be taking. To learn it, it is my recommendation to use the kaloricketabulky.sk web page where you write what you have eaten and you will see how many proteins, carbs and fat it contains.
What are the advantages of including protein as a food supplement in my diet?
It is enough to have a look at the offer in our grocery stores or at the selection of fast foods. If we want to eat something quickly, we grab biscuits, chocolate or, in healthier cases, some fruit. However, those are sources of quick carbs or fat, but no protein. In such case a protein drink is ideal. Its preparation is extremely quick and easy. You only mix protein powder in water and drink it. It is also a very cheap source of proteins if we compare it e.g. with meat. To give 20g proteins to our body, we would have to eat 100g of chicken meat, but you only need 25g of protein powder and you will have the same amount of proteins, which is great. So how to choose the right protein from the wide selection on the market?
Protein drinks have various percentages of protein content, so how to choose the right one?
- protein drinks with a protein content higher than 90%– they are the best quality products you can buy. They are most suitable for supplementing proteins in a diet mode, they have the lowest amount of carbs and fat, but they are usually the most expensive.
- protein drinks with a protein content from 75% to 90%– they contain some carbs and fat, but only minor amounts. About 2g in a 30g dose, which is really not worth mentioning. But they are a great choice.
- protein drinks with a protein content from 50% to 74%– I would recommend such kinds of protein drinks to people who do not wish to lose weight but rather to maintain it. Protein drinks with the lowest protein content are suitable for those who wish to put on weight. Protein drinks with good composition may also serve as a full-value substitute of e.g. one meal per day.
- Whey hydrolysate is the best quality of protein drinks you can buy. Hydrolysate wheat is partially predigested and the human body can thus use it better. Its disadvantage is its high price and often bad, bitter taste (since it is a predigested product).
- Whey isolate is divided into two sub-groups depending on the production type:
- Microfiltered whey isolate(CFM). It contains 90-95% proteins and minimum fat and carbs, it is well tolerated by the human body and easily digested also by those with lactose intolerance.
- Ion-exchange whey isolate. It is produced from fresh sweet whey. It does not contain any fat or lactose and is perfectly usable.
- Whey concentrate is the most frequently sold kind of protein due to its price and its relatively good usability. It contains more fat and carbs than isolate and hydrolysate.
- quick proteins (whey and hydrolysate proteins). They are most suitable after your workout or if you need to take quick proteins which are absorbed easily.
- proteins with gradual absorption (multicomponent proteins). Ideal throughout the whole day, e.g. as a substitute for one meal.
- slow proteins (particularly casein proteins) are recommended mainly for night time.
What protein sources are used in protein drinks?
The most frequently sold ones are whey (milk) protein drinks. They are affordable, very usable and tasty. We divide them into:
Based on the speed of their absorption, proteins may be divided into:
