Does whey protein lead to cancer?
A new risk revealed Researchers screened 134 products for 130 types of toxins and found that many protein powders contained heavy metals (lead, arsenic, cadmium, and mercury), bisphenol-A (BPA, which is used to make plastic), pesticides, or other contaminants with links to cancer and other health conditions.
Does protein cause breast cancer?
Calibrated total protein intake was not associated with breast cancer incidence or mortality. Higher vegetable protein intake was associated with lower breast cancer incidence and lower risk of death after breast cancer. Higher animal protein intake was associated with higher breast cancer incidence.
Can you get cancer from protein?
The findings were intriguing: People from ages 50-65 who ate high-protein diets were four times more likely to die of cancer – this is in the ballpark of smoking risk, say the authors – compared to people who ate low-protein diets. Even those who ate moderate-protein diets were three times as likely to die from cancer.
Does whey protein affect estrogen?
Although it is not clear why whey protein may down-regulate estrogen synthesis, there may be a link to the activity of CYP 3A4 [30], or similar estrogen influencing biochemical pathways following whey consumption. The potential interaction of whey protein and estrogen synthesis is an area worthy of further study.
Can too much protein cause tumors?
Thus, evidence from both epidemiological and laboratory studies suggests that protein intake may be associated with an increased risk of cancers of certain sites.
Which proteins cause cancer?
Members of the Ras superfamily of small GTPases act as binary switches that regulate numerous biological pathways, including cell proliferation, survival, and motility. Mutations in Ras genes lead to tumor development and are found in more than 30 percent of human cancers.
Can whey protein mess with your hormones?
Whey has been known to trigger hormone issues in some. Whey is a great bioavailable protein source, but since it is still dairy-based, it’s still loaded with casein, which can cause runaway inflammation in some people and further perpetuate hormonal problems.
Is protein good for estrogen?
When it comes to hormonal balance, certain protein sources serve you better than others. Eating protein provides your body with amino acids that are used to produce specific hormones, like estrogen, insulin, and thyroid hormone (to name a few).
Does whey protein have long term side effects?
Consuming whey protein can in fact lead to long-term damage to your kidneys. Too much of whey protein can cause renal damage over a period of time. So check your proportions and talk to a doctor before you start consuming whey supplements. Too much of whey is strongly linked to heart disease risk.
Can whey protein supplements cause cancer?

What are the side effects of whey protein?
Some people have whey protein digestion problems and symptoms such as bloating, gas, stomach cramps, and diarrhea, but most of these side effects are due to lactose intolerance. Lactose is the main carbohydrate in whey protein.
Is whey protein bad for your kidneys?
In a 2011 study, those who consumed whey protein during the experiment experienced increases in plasma urea, urine volume, and urinary calcium excretion, while urine citrate pH decreased. In fact, it indicates increased stress on the kidneys, which is the first step towards kidney disease.
What is the difference between whey and milk?
Milk contains casein, a protein has been suggested to strongly increase cancer growth according to Dr. T. Colin Campbell, the author of The China Study. This is quite controversial and some evidence actually suggests that casein and other milk proteins may be cancer protective.5 Regardless, there is very little in whey. 6.
