We all know how diet plays a pivotal role in overall health, which also covers its influence on cancer risk. Scientific evidence consistently highlights the connection between dietary habits and the likelihood of developing certain types of cancer. While genetics and environmental factors also play a role, a balanced diet can significantly reduce cancer risk, says Dr. Jeyhan B. Dhabhar, cancer physician at Jaslok Hospital & research centre. Here's more to what he said.

Can Your Diet Increase Risks Of Cancer, Doctor Explains

As per Dr. Jeyhan B. Dhabhar, what we eat has a profound impact on our risk of developing cancer. The following four should help you understand this better:

1) Basic Diet

A diet rich in fruits, vegetables, whole grains, and lean proteins provides essential nutrients, antioxidants, and fiber that can lower cancer risk.

2) Antioxidants

Antioxidants, such as vitamins C and E, help neutralize free radicals that damage cells and contribute to cancer development.

3) Fiber

Fiber supports digestive health and reduces the risk of colorectal cancer by aiding regular bowel movements and promoting a healthy gut microbiome.

4) Phytochemicals

Phytochemicals found in plant-based foods, such as carotenoids, flavonoids, and polyphenols, have been shown to possess anti-cancer properties by reducing inflammation and slowing the growth of abnormal cells.

Four Foods That Increase Cancer Risk

Dr. Jeyhan B. Dhabhar says these four food items can increase cancer risk:

1) Processed and Red Meats

Frequent consumption of sausages, bacon, and salami has been linked to colorectal and gastric cancers due to harmful compounds like nitrates and preservatives.

2) Sugary Foods and Beverages

High intake of refined sugars and sugary drinks contributes to obesity, a major risk factor for breast, endometrial, and esophageal cancers.

3) Fried and Charred Foods

Cooking at high temperatures can produce carcinogenic compounds like acrylamide and heterocyclic amines, increasing cancer risk.

4) Alcohol

Excessive alcohol consumption is associated with liver, breast, and esophageal cancers due to its toxic effects on cells and interference with DNA repair mechanisms.

To combat the risk of contracting cancer, the doctor suggests:

  • Incorporating colorful fruits and vegetables into meals.
  • Opting for whole grains instead of refined carbohydrates.
  • Reducing red meat intake and avoiding processed meats.
  • Limiting alcohol and avoiding deep-fried or overly charred foods.

"Remember, every meal is an opportunity to safeguard your health. By making conscious, healthier food choices, we can reduce cancer risk and improve overall well-being," Dr. Jeyhan B. Dhabhar wraps up.
