Are your protein shakes healthy?
Protein shakes, powders, and supplements are incredibly popular with the health conscious crowd. Considering what typical protein shakes promise – sleek muscles, weight loss and a quick, easy “healthy” meal replacement – it’s logical to see why, but is your protein shake safe?
Sadly, the food business is offering ones that are loaded with very prepared denatured proteins, chemicals, additives and different added substances. There’s one thing similar for every one of them – they are processed settling on regardless of whether they are in re genuine food comes into question. Not every single processed foods we put in our body are actually terrible for us – yet understanding what precisely is in your protein shake is basic to choosing whether to expend it, select an option, or cease utilize all together.
NOT CERTIFIED ORGANIC
Most protein powders on the market are not certified organic, nor are they Non-GMO Project Verified. That means all of them might contain GMOs and most definitely contain pesticides that are considered harmful and potentially toxic with long-term exposure. This increased exposure is linked to birth defects, nerve damage, and even cancer. The President’s Cancer Panel has urged us not to consume food sprayed with pesticides and doesn’t believe any amount is safe. Because of this reason, I can’t imagine willingly wanting to spend a serious chunk of change (protein shakes are expensive!) to buy any of these listed products as a way to help build muscle, lose weight or replace a meal.
If your protein shakes contain these, then it’s not safe!
Many weight loss shakes contain heavy metals like arsenic, cadmium, and lead. Cadmium raises special concern because it accumulates in and can damage the kidneys, the same organs that can be damaged by excessive protein consumption.
Many protein drinks use soy protein concentrate or soy protein isolate in conjunction with other proteins. Over 90% of the soy produced in this country is GMO and contaminated with Roundup herbicide, but that’s not the only reason to avoid soy protein. When soy is looked at from a macronutrient perspective, it can give the illusion of a very healthy food – full of plant based protein, essential amino acids and fiber. However, the soy that is grown and produced today is largely hybridized, making the amino acids largely indigestible leading to digestive issues that have caused many people to be allergic to soy.
Maltodextrin & Fibersol
Calling out an ingredient filler like maltodextrin may make you think I’m being nitpicky – but is this carb substitute that is likely derived from genetically modified corn really necessary in protein powders? Maltodextrin can be used to make the substance “fibersol”. This is made by heating maltodextrin at very high temperatures and treating it with enzymes and acids to make a fiber your body simply can’t digest and makes you feel artificially full. If you are eating enough plant-based foods, there is no reason to supplement with this type of chemically derived fiber. Fibersol is just another additive that does absolutely nothing for your long term health. Why not add a real food like spinach or a banana to your smoothie instead?
Acesulfame Potassium or Acesulfame K
This is the most common form of artificial sweetener available in protein drinks (and tons of other processed foods) today and according the Center for Science in the Public Interest (CSPI) it is anything but safe. CSPI reported the safety tests of acesulfame-K that were conducted in the 1970s were inadequate. Specifically, two rat studies suggest that the additive might cause cancer, but these studies were never addressed by the FDA before they approved the substance to also be used unregulated in soft drinks. In addition it is mentioned that large doses of acetoacetamide (a breakdown product of this sugar) have been shown to affect the thyroid in rats, rabbits, and dogs.
Whey Protein Isolate
Whey protein isolate is highly processed, unlike whole protein food concentrate. Most whey protein isolates start from ultra-pasteurized conventional milk that has antibiotics and growth hormones and are then exposed to acid processing, stripping alkalinizing minerals, naturally occurring vitamins and lipids. This processing makes whey protein isolate over acidifying in the body. Chronically consuming whey protein isolate without appropriate balance of alkalizing foods, can acidify your body and over time increase your vulnerability to degenerative disease. This overly processed form of whey can be found in a lot of popular protein drinks.
Well lucky for you, real food is enough to fulfill your protein requirements, here are some food which make good protein sources:
Meat sources of protein – beef, pork, poultry, eggs, yogurt, cheese, fish (very important to choose organic if you go this route)
Vegetarian sources of protein – legumes (dry beans, lentils, and peas), nuts and seeds (almond butter, sunflower seeds, hemp seeds), whole grains (oatmeal, quinoa, brown rice, pasta), dark leafy vegetables, and some fruits like avocado.
