Lets Jump straight to the point
A - What is Whey powder ?
Well in its most simple form it is a mixture of proteins isolated from whey, the liquid material created as a by-product of cheese production then purified and processed to form the powder.
The most important fact that people tend to overlook is the amount of processing and various other additives , Fillers, chemicals, preservatives etc that end up in these whey powders that companies market and sell as a necessity for reaching daily protein requirements, making foods healthier or a necessity for building muscle, staying fit or losing weight.
B - Why do we rely on plant based protein and aren’t adding whey powders to our granolas ?
Good Question. Lets take a look at some Research , studies and also a few things you might find in these processed powders.
1- In 2018 a nonprofit called the Clean Label Project released a report about toxins in protein powders. https://cdn1.cleanlabelproject.org/app/uploads/20180319002804/Protein-Powder_Infographic-0111.jpg
In which they screened and tested 134 of the top selling protein powder products.
The results were shocking !
70% of the protein powder products tested had detectable levels of lead
74% of the protein powder products tested had detectable levels of Cadmium
55% of the protein powder products tested had detectable levels of BPA
Other than these , some were even found to have detectable levels of arsenic, mercury , pesticides and other contaminants.
2- A 2012 study published in Nutrition & Metabolism identified that the specific amino acids in whey protein stimulate beta cells to secrete more insulin than a similar amount of carbohydrate from white bread.
3- This one is about Whey Protein Absorption – A review on the rate of protein absorption published in 2006 in the International Journal of Sport Nutrition and Exercise Metabolism reported that whey protein isolate absorbs at a rate of about 8g/hour. This is in part due to the fact that whey is not broken down into small enough peptides by our body’s natural enzymes in time to be absorbed.
Considering a 2 hour window for whey protein to be absorbed , thats about 16gm of protein that your body would be able to absorb. So why burden it with that 30-40gm serving ? Kind of pointless right ?
Apart from the possibility of hidden toxins and kind of pointless protein quantities lets look at some of the other ingredients that go into these powders.
1. Artificial Sweeteners
Acesulfame Potassium and Sucralose are the two most common found in protein powders. Although they have no calories, research finds they stimulate your appetite, increase sugar cravings, and promote fat storage and weight gain.
2. Artificial Flavours
Artificial flavours are chemical mixtures made with synthetic ingredients in a lab. They’re produced by fractional distillation and chemical manipulation of various chemicals.
3. Natural Flavours
Natural Flavours are almost the exact same thing as Artificial Flavours, but the base is derived from substances found in nature.
But there is more.
These flavours typically contain preservatives, emulsifiers, solvents and other additives, which can make up a majority of the flavouring and the best part is that None of these are disclosed on the ingredient lists.
4. Various forms of sugars
It’s added to protein powders in many different forms – you will see ingredients like corn syrup solids, fructose, maltodextrin, dextrose.
We will need another article to give justice to these harmful substances!
5. Synthetic Vitamins
These are made in labs from a variety of different sources and are not absorbed by your body as well as naturally present vitamins that you can get from consuming whole foods . You’ll see them listed on ingredient lists in forms like Thiamine (vitamin B1), Riboflavin (vitamin B2), and Ascorbic Acid (vitamin C).
These are just a few of the harmful things that are found in protein powders and we haven't allowed any of these "not so good" ingredients into our foods along with a big list of other ingredients that we said no thanks to as well.
Its Simple, No Whey = No uncertainty.
Keeping our foods clean is a part of our food movement and a part of our bigger mission to create foods that have a positive impact on you and our society.
