What You'll Learn
Goat cheese is a safer alternative to cow's milk products
Dairy products, including milk and cheese, contain natural hormones such as oestrogen and progesterone. These hormones are present in the milk of various animals, including cows, goats, and humans. While dairy products are a source of these hormones, the levels can vary depending on the type of milk and its processing.
Goat cheese is often touted as a healthier alternative to cow's milk cheese. One reason for this is the difference in oestrogen levels between the two types of milk. Studies have shown that goat milk contains significantly lower levels of estrogens compared to cow milk, including organic cow milk. This is particularly important for individuals concerned about steroid hormone consumption, especially those at high risk of or diagnosed with hormonal cancers, such as prostate, breast, and ovarian cancers.
The higher levels of oestrogen in cow's milk can be attributed to the fact that a significant portion of it comes from pregnant cows, who have much higher estrogen levels—up to 33 times more than their non-pregnant counterparts. This factor contributes to the elevated estrogen content in cow's milk and the resulting products, including cheese.
In addition to the natural hormones present in cow's milk, it is worth noting that the majority of dairy cows in the US are injected with genetically modified growth hormones to increase their milk production. These artificial hormones can further disrupt the hormonal balance in consumers. Goat cheese, on the other hand, is less likely to be sourced from animals treated with such hormones, making it a safer alternative for those concerned about hormone intake.
While the occasional consumption of goat's milk yogurt or cheese is generally considered acceptable, it is important to remember that more research is needed to fully understand the long-term effects of dairy consumption on cancer risk and other diseases. However, for those seeking to reduce their exposure to hormones and potential cancer risks, goat cheese and dairy products may be a preferable choice over cow's milk alternatives.

Goat milk has lower estrogen levels than cow milk
Dairy products, including milk and cheese, contain natural hormones such as oestrogen and progesterone. These hormones are present in the milk of various animals, including cows, goats, and humans. While all milk contains hormones, the levels can vary depending on the type of milk and its source.
Goat milk has been found to have significantly lower levels of estrogens compared to cow milk. A study by Farlow et al. (2012) revealed that the average daily intake of estrogen for cow milk drinkers was 24-54 ng per day (based on 3/4 cup of milk per day), while for goat milk drinkers, it was only 10 ng per day (also based on 3/4 cup of milk per day). This difference in estrogen levels is partly due to the fact that a significant amount of cow milk comes from pregnant cows, who have much higher estrogen levels than non-pregnant cows.
The higher estrogen content in cow milk can have implications for consumers, especially those at high risk of or diagnosed with hormonal cancers, such as prostate, breast, and ovarian cancers. The consumption of dairy products has been linked to an increased risk of certain cancers, and as estrogens are considered a major pathway for these cancers, the impact of dairy intake on estrogen levels is a crucial consideration.
While goat milk has lower estrogen levels, it is important to note that it still contains hormones. The effects of long-term consumption of goat milk or any dairy product are not yet fully understood, and more research is needed to determine the specific impact on health. However, for individuals concerned about steroid hormone consumption or looking to reduce their potential cancer risk, choosing goat milk and dairy over cow dairy may be a preferable option.

Dairy products are linked to an increased risk of cancer
Dairy products have been linked to an increased risk of cancer, with research suggesting that the hormones and fat content in milk, cheese, and other dairy products may be contributing factors.
Dr. Neal Barnard, an activist, author, and doctor, has asserted that cheese contains trace levels of estrogen and other chemicals given to pregnant cows, which remain in their system and are passed on to humans through their milk. Regular consumption of these hormones can disrupt the body's natural hormonal balance, increasing the risk of hormone-related cancers such as breast, ovarian, and prostate cancer.
Several studies have examined the link between dairy consumption and cancer risk, with mixed results. Some studies have found a positive correlation between dairy intake and the risk of breast, ovarian, and prostate cancers, while others have suggested a protective effect, particularly for colorectal and breast cancers. For example, a study on Western populations indicated that dairy products may be associated with a lower risk of colorectal cancer and a higher risk of prostate cancer, but found no clear link to breast or other types of cancer.
The impact of dairy on cancer risk may vary depending on geographical location and dietary habits. A large-scale study conducted in China, for instance, found that greater dairy consumption was associated with a higher incidence of liver and breast cancer. This could be due to the presence of female sex hormones in cow's milk, such as estrogen and progesterone, which are linked to an increased risk of breast cancer. Additionally, saturated and trans-fatty acids from dairy products may contribute to the increased risk of liver cancer.
Furthermore, the type of dairy product consumed seems to play a role. A 2017 study found that women who consumed higher amounts of American, cheddar, and cream cheeses had a 53% higher risk of breast cancer, while yogurt was associated with a lower risk. Similarly, men who consumed three or more servings of dairy products per day had a significantly higher risk of death due to prostate cancer compared to those who consumed less.
However, it is important to note that the overall evidence on the link between dairy consumption and cancer risk is inconsistent, and more research is needed. While some studies suggest a correlation, others have found no association or even a protective effect. Additionally, dairy products are a source of important nutrients like protein, vitamins, and minerals, so any dietary changes should be carefully considered to ensure adequate nutrient intake.

Dairy cows are injected with artificial hormones
Dairy products have been linked to an increased risk of certain cancers, including breast, uterine, ovarian, and prostate cancer. This has been attributed to the presence of estrogen and other hormones in dairy products, which can disrupt the body's natural hormonal balance.
While all milk, including goat's milk, naturally contains small amounts of estrogen and other hormones, the practice of injecting dairy cows with artificial hormones has raised concerns among consumers. Dairy cows are often treated with bovine somatotropin (bST), a synthetic growth hormone, to increase milk production. The use of bST in dairy cows has been approved by the FDA, which has determined that the hormone does not promote biological activity in humans and that the milk and meat from treated cows are safe for human consumption. However, some people still choose to avoid dairy products due to concerns about the potential health risks associated with artificial hormones.
BST is typically administered to dairy cows through subcutaneous injections every 14 days during the lactation period, which can last for approximately 10 months. The FDA has conducted studies and concluded that Posilac™, a brand name for bST, is safe for use in healthy dairy cows, although some side effects have been observed. These side effects are considered manageable under normal farming conditions, and the product labeling provides information on potential side effects to help farmers make informed decisions.
In addition to bST, the FDA has also approved steroid hormone implants for use in beef cattle and sheep. These implants, typically placed under the skin on the backside of the animal's ear, increase the animal's growth rate and feed efficiency. The FDA establishes safe limits for hormones in meat, ensuring that the amount of additional hormones in the edible tissues remains below the safe level for human consumption. The approval process for these drugs includes toxicological testing and evaluating the safety of the food from treated animals.
While the FDA and other regulatory agencies have deemed the use of artificial hormones in dairy cows safe, some consumers remain cautious about the potential impact on their health and continue to seek alternatives to dairy or opt for organic or plant-based options.

Dairy fat is linked to breast cancer
Dairy products have been the subject of much research in recent years, with some studies suggesting a link between dairy fat and breast cancer. The relationship between dairy consumption and breast cancer is highly controversial, with some studies finding a positive correlation, others a negative correlation, and some no correlation at all. However, the consensus seems to be that dairy fat, particularly from high-fat dairy products, is linked to an increased risk of breast cancer.
One possible explanation for this link is the presence of estrogen in dairy products. Estrogen is a fat-soluble hormone that occurs naturally in milk, and its levels are higher in whole milk than in skim milk. Goat cheese, in particular, has been found to have even higher levels of estrogen than other types of cheese. When small amounts of estrogen are introduced into the body, it can increase the risk of hormone-related cancers, such as breast, uterine, and ovarian cancer.
The impact of dairy products on breast cancer risk may also depend on the type of dairy and the age of the consumer. Some studies suggest that fermented dairy products, such as yogurt and cheese, can reduce the risk of breast cancer in postmenopausal women, while high-fat dairy products are more harmful to premenopausal women. Additionally, the calcium and vitamin D in dairy products may be linked to a decreased risk of breast cancer.
While the exact nature of the link between dairy fat and breast cancer is still being investigated, it is clear that dairy products can have a significant impact on health. Dr. Neal Barnard, an activist and author, has advocated for reducing dairy consumption, particularly cheese, due to its high levels of estrogen and other chemicals that can disrupt the body's natural hormonal balance. He has proposed adding warning labels to cheese products, stating that they may increase the risk of breast cancer.
