The foods we consume in our daily lives can have a profound effect on our overall well-being. Isn’t that a line we’ve heard a lot of times? While many are cognizant of the immediate impacts of diet on weight and energy levels, the long-term implications, particularly concerning chronic diseases, often evade notice. Did you know that there is a strong link between diet and gastric cancer? This blog seeks to uncover the specific dietary elements researchers have linked to an elevated risk of developing gastric cancer. It offers insights into the foods people often unwittingly include in their daily diets without fully realising the long-term risks to their health.

Understand Gastric Cancer 

Gastric cancer is a cancer of the stomach. It primarily starts in the inner lining of the stomach but can manifest in any region of the organ. Some of the common symptoms of gastric cancer include abdominal pain and unexplained weight loss. Two major factors linked to its development are Helicobacter pylori infection and diet. Extensive research all over the world, including data from World Cancer Research Fund International, have identified diet as a major risk factor. Furthermore, data on the prevalence of gastric cancer across regions suggests that local dietary habits and cultural practices impact its occurrence. Since diet is a modifiable element that can minimise the risk of a problematic condition such as gastric cancer, knowledge about the foods to include and remove from our diet can be very useful.

Dietary Factors Elevating Gastric Cancer Risk 

Although there are no specific foods that increase the risk of gastric cancer, several food groups in various studies have been identified to add fuel to the fire. Let’s explore some of these food groups that are considered to worsen the stomach environment and leave an individual vulnerable to developing gastric cancer.

The Salty Culprit: Salt and Salt-Preserved Foods

• Why It’s Risky: High salt intake can damage the stomach’s mucous lining, creating an environment conducive to the effects of carcinogens. Salt can also increase the growth and activity of Helicobacter pylori, the bacterium linked to gastric cancer and gastritis.
• Evidence Snapshot: High-salt diets in certain Asian regions correlate with increased gastric cancer rates.
• Quick Tip: Choose a diet that emphasises fresh foods over salt-preserved options. Moreover, explore the use of herbs and spices as flavorful alternatives to salt. Low-salt diet is good for gastric cancer patients and even those looking for ways to prevent it.

Processed Meats: A Hidden Danger

• Loaded with Nitrates and Nitrites: These compounds, commonly used as preservatives in processed meats, get converted in the stomach into carcinogenic N-nitroso compounds. A diet high in processed meat can damage stomach cells and elevate the risk of stomach cancer.
• Evidence Snapshot: Over consumption of processed meats has been linked to various cancers, including gastric cancer.
• Quick Tip: Selecting the right diet is essential for individuals diagnosed with gastric cancer. It’s advisable to prioritise fresh, lean meats over processed alternatives. Such a diet will also help relieve the symptoms of gastric cancer. Furthermore, consider choosing organic meats that are free from harmful additives.

Dark Side of Open Flames: Smoked and Grilled Foods 

• Why It’s Risky: Cooking foods at high temperatures or directly over a flame can produce harmful compounds such as polycyclic aromatic hydrocarbons (PAHs) and heterocyclic amines (HCAs). These compounds are carcinogens well known to increase the risk of gastric cancer.
• Evidence Snapshot: Diets high in smoked or grilled foods correlate with a higher risk of gastric cancer, especially as stomach cancer risk by age increases.
• Quick Tip: A stomach cancer prevention diet should include experimentation with alternative cooking methods such as steaming, boiling, or baking. Additionally, marinades with herbs and spices can help minimise the formation of harmful compounds during cooking.

Nature’s Shield: The Importance of Fresh Produce

• Why Some Miss Out: Fresh fruits and vegetables are rich in antioxidants, fibre, and other phytochemicals that neutralise carcinogens and protect the stomach lining. A diet low in these protective factors lacks the necessary components to combat the harmful effects of carcinogens.
• Evidence Snapshot: Populations with poor access to fresh fruits and vegetables often have higher rates of developing gastric cancer.
• Quick Tip: Diversify your diet by consuming a variety of fruits and vegetables. Choose organic produce to reduce exposure to pesticides and chemicals. Such a diet will help not only in the prevention of gastric cancer but can also relieve symptoms for those undergoing treatment for gastric cancer.

Dietary Defenders against Gastric Cancer 

Prevention is indeed better than cure, especially when it concerns gastric cancer. We have already learnt how diet emerges as a critical factor in this preventive endeavour. Up till now, we have presented foods to avoid. In this section, we discuss specific foods and dietary components being recognised as formidable allies in the battle against this malignancy.

Whole Grains: Nature’s Gut Guardian 

• Why They’re Beneficial: Whole grains are fibre-rich, supporting a healthy gut environment.
• Evidence Snapshot: Research suggests that diets high in whole grains are linked to a decreased risk of gastric cancer.
• Quick Tip: Enhance your stomach cancer prevention diet by including whole-grain alternatives. Consider incorporating oats, barley, and quinoa for added benefits.

Green Tea: The Antioxidant Powerhouse 

• What’s Inside: Green tea contains Epigallocatechin gallate (EGCG), a powerful antioxidant.
• Evidence Snapshot: Studies suggest that regular green tea consumption can offer protective benefits against gastric cancer.
• Quick Tip: Make a habit of drinking green tea regularly.  Opt for high-quality, organic green tea for maximum benefits.

Allium Vegetables: More Than Just Flavour 

• Why They’re Special: Allium vegetables contain sulphur compounds known for their anti-cancer properties.
• Evidence Snapshot: Research indicates that including garlic, onions, and leeks in your diet can lower the risk of gastric cancer.
• Quick Tip: Enhance your meals by incorporating a variety of allium vegetables. Add chives and shallots to the mix for flavour and health benefits.

Probiotics: The Friendly Fighters

• What They Do: Probiotics promote a balanced gut microbiome that can not only help create an environment to prevent the risk but also help relieve the symptoms of gastric cancer.
• Evidence Snapshot: According to research, incorporating probiotic-rich foods into your diet can protect against gastric disturbances.
• Quick Tip: Boost your probiotic intake by including fermented foods in your diet. Yoghurt, kefir, and kimchi are excellent sources of beneficial bacteria.

Vitamin C and flavonoid rich oranges and lemons, and beta-carotene rich carrots and sweet potatoes are also useful for those undergoing treatment for gastric cancer and relieving its symptoms.

Conclusion

Navigating the intricate relationship between diet and gastric cancer can be daunting. However, understanding this connection offers a powerful tool in the quest for optimal stomach health. Individuals can chart a proactive path towards reducing their gastric cancer risk by being mindful of specific dietary culprits and embracing protective foods. As the saying goes, “Let food be thy medicine.” In the context of gastric health, this ancient wisdom holds profound relevance. One can pave the way for a healthier tomorrow by making informed dietary choices today.
