Although no food alone can prevent breast cancer, there are ingredients that can help reduce the risk of developing the disease. Linseed can play an important role in hormonal health and body protection.

ANDalthough there is no food capable of preventing breast cancer alone, including some recommended by doctors in the diet can make a difference.
In this sense, the linseed are a nutrient-rich ingredient that can contribute to reducing the risk of breast cancer. They are rich in nutrients such as fiber, omega-3 and lignanas.
“ In 2023 it was estimated that 28.3% of the overall burden of breast cancer (measured in disability-adjusted years of life) it was attributed to modifiable risk factors, with food risks being the main contributor“, noted oncologist Lisa Reale.
Oncologists highlight the benefits of linseed to health.
Why Linseed Helps Prevent Breast Cancer
Rich vegetable source of omega-3
The ground linseed contains alpha-linolenic acid (ALA), an omega-3 of plant origin, an important part of an anti-inflammatory diet, explains oncologist Amar Rawari.
Studies suggest that increased omega-3 intake is associated with a lower risk of breast cancer.
Contains lignanas
Milled linseed is a source of lignanes, plant compounds that act as antioxidants and phytoestrogens in the body.
Phytoestrogens, such as lignans, are plant compounds similar to oestrogen and have similar effects on the body, although less intense.
Although further research is needed to prove that Lignanes reduce the risk of breast cancer when they bind to oestrogen receptors, it is believed that they contribute to the general hormonal balance, says physician Deena Graham.
Preliminary research suggests that intestinal bacteria convert lignans into active compounds such as enterolactone and enterodiol, Graham notes. These compounds may influence oestrogen signaling.
Rich in fiber
The ground flaxseed provides 3.5 grams of fiber per serving of 15 grams (about 1.5 to 2 tablespoons). “Increased fiber intake has been associated with a lower risk of breast cancer”, says Reale.
The insoluble fiber of ground linseed binds to the excess oestrogen and bile acids circulating in the digestive tract, eliminating them from the body by feces, preventing resorption and reducing oestrogen levels, Graham explains.
The flaxseed fibers can also help control the weight. “The soluble fiber absorbs water, delaying digestion and stimulating the release of satiety hormones, which keep the sensation of satiety longer,” Graham explains.
In addition, increased fiber intake may improve insulin sensitivity and may influence hormonal and growth signaling pathways, impacting the risk of breast cancer.
