The use of whey protein as a dietary strategy is widespread in the field of oncology. The two types of whey protein, sweet or acid, result from several processing techniques and possess distinct protein subfraction compositions. Mechanistically, whey protein subfractions have specific anti-cancer effects.
Full Answer
Is whey protein good for cancer patients?
The lactoferrin component of the whey protein facilitates apoptosis, inhibits angiogenesis and boosts carcinogen-metabolising enzymes. It is most interesting to note that cancer cells and normal cells react differently to nutrients and drugs that affect GSH status.
What are the medical uses of whey protein?
Whey is also used to lower total and LDL cholesterol and to reduce blood pressure in hypertensive patients. [ 2] In asthma patients whey protein has been linked to an improved cytokine response. [ 3] And currently, whey protein is being used as a cysteine donor for the modulation of glutathione (GSH) in cancer treatment. [ 4]
What is the best protein supplement for cancer patients?
Powdered Milk. Powdered milk contains both whey and casein to contribute to your protein intake. It is recommended as a supplement by both the University of California San Francisco Medical Center and the Washington University School of Medicine Siteman Cancer Center for your cancer diet.
Do whey protein subfractions have specific anti-cancer effects?
Mechanistically, whey protein subfractions have specific anti-cancer effects. Alpha-lactalbumin, human α-lactalbumin made lethal to tumor cell, bovine α-lactalbumin made lethal to tumor cell, bovine serum albumin, and lactoferrin are whey protein subfractions with potential to hinder tumor pathways.

Products such as double strength milk, whey protein powder, pea protein isolate, soy protein, or hemp protein powders are good options to supplement your meals.
Does whey increase cancer risk?
Whey Proteins. Both animal and cell culture studies have proven that the anti-carcinogenic qualities of whey protein are associated with the sulphur amino acid cysteine, a substrate that combines with glutamate to form γ-glutamylcysteine.
Does protein feed cancer cells?
Scientists Find a Pair of Proteins Control Supply Lines That Feed Cancer Cells. In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow.
Should cancer patients avoid 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.
Is protein powder good for chemo?
CHICAGO—Whey protein isolate supplementation combined with nutritional counseling enabled malnourished patients with advanced cancer to better tolerate chemotherapy, according to results from a trial presented at the 2019 annual meeting of the American Society of Clinical Oncology (abstract 11598).
What is whey protein supplementation?
Whey protein supplementation is a dietary strategy widely used in the field of oncology.
Does WP increase glutathione?
Regardless of this distinction, WP may enhance glutathione synthesis due to its high content in cysteine and methionine [ 52 ]. Enhanced glutathione levels have been implicated in several types of cancer, presenting both protective (healthy cells) and pathogenic (cancer cells) roles [ 53 ].
Is whey protein good for cancer?
Cancer remains a public health challenge in the identification and development of ideal pharmacological therapies and dietary strategies. The use of whey protein as a dietary strategy is widespread in the field of oncology. The two types of whey protein, sweet or acid, result from several processing techniques and possess distinct protein ...
Does whey protein cause apoptotic activity?
In addition, whey protein-fed mice also presented higher apoptotic activity by MCP-1 ( monocyte chemoattractant protein-1) in serum compared to casein protein [ 92 ]. Other types of whey (excluding bovine whey) have recently gained traction in cancer research that suggests possible utility in this area.
Does whey protein contain leucine?
Furthermore, whey protein possesses a high content of leucine and other essential amino acids, compared to other proteins ( Table 3 ). One positive effect of leucine to mitigate cancer-related cachexia is the stimulation of muscle protein synthesis at lower amounts of total protein consumption [ 120 ].
Why is GSH increasing in cancer cells?
The reason for this is not yet clear, but perhaps the increase in GSH in the rapidly growing cancer cell may be the body’s response to the appearance of carcinogens and the accumulation of reactive oxygen species. More research is needed.
How does depletion of GSH occur in cancer cells?
One answer is that depletion of GSH can be facilitated by feeding whey protein. The most likely mechanism is an increase in the efflux of GSH out of the mitochondria with a simultaneous inhibition of its accumulation. The result is an overall depletion of GSH in the mitochondria in cancer cells. [ 7 ]
What is the role of GSH in the cell?
Through its associated enzymes, GSH has a major role, in cell protection against free radicals, ionising radiation, reactive oxygen species and carcinogens. [ 7 ] After feeding with dietary whey protein there is an increased level of GSH in serum and tissues.
Does whey protein inhibit angiogenesis?
The lactoferrin component of the whey protein facilitates apoptosis, inhibits angiogenesis and boosts carcinogen-metabolising enzymes. It is most interesting to note that cancer cells and normal cells react differently to nutrients and drugs that affect GSH status.
Is whey protein a precursor to glutathione?
Precursors for Glutathione. Animal studies have consistently shown that whey proteins are superior to other dietary proteins for the suppression of tumour development. This is thought to be due to the high quantity of cystine/cysteine and gamma-glutamylcyst (e)ine dipeptides in the whey protein subfractions.
Is GSH good for cancer prevention?
GSH in Cancer Prevention. This also makes sense when it comes to prevention. Whey protein may be able to furnish healthy cells with enough GSH to enable them to control the impact of any stray carcinogens or ROS before they have morphed into rapidly proliferating cells or a virulent tumour load.
Is whey protein good for asthma?
In asthma patients whey protein has been linked to an improved cytokine response. [ 3] And currently, whey protein is being used as a cysteine donor for the modulation of glutathione (GSH) in cancer treatment. [ 4]

Intervention trials have demonstrated that nutritional counseling can improve energy balance, nutritional status and quality of life in patients undergoing chemo-radiotherapy. Oxidative stress plays a role in the tumor-cytotoxic effect of cancer chemotherapy and radiotherapy but may also play a role therapy-related adverse events such as an ...
Does whey protein help with cancer?
The nutritional properties of whey protein have recently raised attention. In view of the high content in cysteine these proteins can positively stimulate the synth esis of glutathione which, in turn, could contribute to the modulation of whole-body and cellular redox state. However, evidence on the role of this dietary intervention in cancer ...

Can cancer cause hypermetabolism?
With some cancers, the metabolic processes can cause a situation known as hypermetabolism that affects how the body uses proteins, fats, and carbohydrates. With hypermetabolism you may need to increase your calorie and protein intake. Discuss this with your physician or registered dietitian. NUTRITION TIP.
Snack as needed
During cancer treatment your body often needs extra calories and protein to help you maintain your weight and heal as quickly as possible. If you’re losing weight, snacks can help you meet those needs, keep up your strength and energy level, and help you feel better.
Tips to get more calories and protein
Eat several small snacks throughout the day, rather than 3 large meals.
