Consuming dairy products might reduce the risk of developing breast cancer.
The researchers conducted a systematic literature review where they scrutinized various databases for studies published in English up to January 2022. They began with 82 articles, but only 18 met their pre-set inclusion criteria. The studies varied in type - nine were prospective, seven were retrospective, and two were cross-sectional.
The results indicated an inverse relationship between dairy consumption and the risk of developing breast cancer. However, the effect of different types of dairy products and the exact dose-response relationships on breast cancer risk remains unclear. Nevertheless, this review provides a foundation for considering dairy products in preventive strategies to reduce breast cancer occurrence.

Manuka honey has demonstrated the potential to inhibit the proliferation of human breast cancer cells and stimulate apoptosis in these cells.
2024 Nutrients Manuka Honey Inhibits Human Breast Cancer Progression in Preclinical Models Márquez-Garbán DC, Yanes CD, Llarena G, Elashoff D, Hamilton N, Hardy M, et al.
Animal Study Breast Cancer Honey
In the experiment, Manuka honey was applied to three different types of cells: MCF-7 human breast cancer cells, MDA-MB-231 breast cancer cells, and non-malignant human mammary epithelial cells. The concentrations applied ranged from 0.3 to 5.0% to observe different effects. In addition to inhibiting cancer cell proliferation, the honey was tested for its ability to cause apoptosis (cell death) among the MCF-7 cells. It was also compared to the effects of tamoxifen, an antiestrogen medication used in breast cancer treatment.
The results showed that Manuka honey was able to significantly inhibit the proliferation of MCF-7 cells, though its effects were less pronounced in the MDA-MB-231 breast cancer cells. The non-malignant cells were not affected. The honey's antitumor activity was comparable to that of tamoxifen. Moreover, Manuka honey stimulated apoptosis in the MCF-7 cells. It was also observed that the honey activated AMPK, which inhibits specific cellular growth signals, and reduced STAT3 levels, a protein often elevated in tumors.
Clinical studies related to breast cancer have revealed that honey is effective in increasing blood cell counts, interleukin-3 levels, and quality of life.

Clinical Study Breast Cancer Honey Osteoporosis
In relation to breast cancer, in vitro experiments revealed the anti-proliferative and pro-apoptotic impact of honey on breast cancer cells, as well as their increased apoptosis. Animal studies have shown that honey reduces the number, growth rate, volume, and tumor weight. Findings from clinical trials reported its immunomodulatory properties showing that honey is effective in increasing leukocyte and platelet counts, IL-3 levels, and quality of life. In this context, the potential role of honey and its oligosaccharides as prebiotics for specific beneficial bacteria might be examined in future clinical studies.
Preclinical studies related to osteoporosis have reported favorable effects of honey on cortical and trabecular bone microstructure, bone strength, and oxidative stress.

Clinical Study Breast Cancer Honey Osteoporosis
Honey is able to protect the bone mainly due to antioxidant and anti-inflammatory properties, primarily through its content of polyphenols, which act on several signaling pathways, resulting in anabolic and antiresorptive effects. From the group of polyphenols, the anti-osteoporotic impact of quercetin, kaempferol, and luteolin was recorded. In addition, vitamin D3 and its hydroxyderivatives with antioxidant properties were also detected in honey. Vitamin D3 supplementation was found to have protective effects on the inhibition of bone loss and BMD in both experimental animals and postmenopausal women.
Carrot and carotene consumption could diminish the risk of a wide range of negative health consequences, including multiple types of cancer.
2023 Journal of the Science of Food and Agriculture Carrot and carotene and multiple health outcomes: an umbrella review of the evidence Yi X, Li J, Liao D, Peng G, Zheng X, Xu H, et al.
Review Article Alzheimer's Disease Anticancer Breast Cancer
An umbrella review methodology was adopted to identify connections between carrot and carotene intake and various health outcomes. We turned to databases such as Web of Science, PubMed, and Embase to find the needed data. The analysis included the collected evidence from both interventional and observational studies that focused on carrots, carotene, and any related health impact. To estimate the summary effect size for each correlation, both random and fixed effects models were employed.
The study reviewed a total of 1329 studies and utilized the data from 30 meta-analyses with 26 health outcomes that fit the eligibility requirements. These featured outcomes related to various types of cancer, fractures, age-related cataract, sunburn, and Alzheimer's disease. The associations were analyzed between the health outcomes and the intake of carrots, intake of carotene, and serum carotene levels.
Crocin, a compound derived from saffron, has shown considerable potential in hindering tumor growth and improving immune status, across various malignant tumors.

Review Article Anti-Tumour Breast Cancer Cervical Cancer
The methodology for the study involved an in-depth review of modern pharmacological studies that have analyzed the therapeutic effects of crocin, a natural compound that can be extracted from saffron. Various anti-tumor effects were assessed including the induction of tumor cell death (apoptosis), restrictions on tumor cell proliferation, and potential barriers to invasion and metastasis of these cells. The potential for enhancement of sensitivity to chemotherapy and improvement of immune status were also examined.
Following the review, the study revealed that crocin has significant anti-tumor properties. It showed that this natural compound can induce apoptosis in tumor cells, inhibit their expansion and progression, and even prevent their invasiveness and metastasis. Furthermore, crocin demonstrated the potential to enhance the body’s responsiveness to chemotherapy and help boost the immune system. These effects were observed across a range of different malignant tumors, including stomach, liver, cervical, breast, and colorectal cancers.
