In the modern world, the rise of fast-paced lifestyles and processed foods has led to an increasingly important issue: the amount of salt we consume. This article will delve deeper into the negative impact of high salt consumption on our digestive system. From minor issues like bloating to major consequences such as affecting kidney function, we will explore how salt affects the body and how we can maintain a balanced diet to protect the health of our digestive system. Let’s uncover important health messages that few know about on the journey of self-care.
I. High salt consumption impacts the digestive system and its link to serious health problems
High salt consumption is not merely a dietary habit but also a significant factor behind many serious health problems related to the digestive system. This has been proven through numerous scientific studies and medical observations. Adults who consume more than 5g of salt per day put themselves at a higher risk of developing health issues, especially concerning the digestive system.
The salt intake level among Vietnamese adults, particularly around 9.4g per day, far exceeds the World Health Organization (WHO) recommended threshold, being twice as high. This creates an unforeseen situation, making the negative impact on the digestive system more dangerous and widespread. High salt intake can disrupt the protective barrier of the stomach lining, increasing the risk of inflammation, ulcers, and gastrointestinal cancer.
Overall, high salt levels not only affect the structure of the lining but also create favorable conditions for Helicobacter pylori (H.P) bacteria to grow and thrive more vigorously in the acidic stomach environment. This can increase the risk of serious health problems such as stomach and duodenal ulcers, and even gastrointestinal cancer.

II. High salt consumption among Vietnamese people and its link to gastrointestinal diseases
Salt consumption levels among Vietnamese people are becoming a serious health issue, especially as it is closely linked to gastrointestinal diseases. Reality shows that Vietnamese adults consume about 9.4g of salt per day, double the amount recommended by the World Health Organization (WHO). Exceeding the recommended consumption level creates a negative impact on the digestive system, particularly concerning gastrointestinal diseases.
High salt consumption can disrupt the protective barrier of the stomach lining. This change not only makes the lining more vulnerable to damage but also increases the risk of developing gastrointestinal diseases such as ulcers and other serious problems.
High salt content in the diet also creates favorable conditions for Helicobacter pylori (H.P) bacteria to grow and thrive vigorously in the acidic stomach environment. This not only increases the risk of stomach ulcers but also enhances the likelihood of developing gastrointestinal diseases, including dangerous cancers.
Overall, high salt consumption in Vietnam is not just a personal issue but also affects public health. This poses a major challenge to the healthcare system and requires emphasis on reducing salt in the daily diet, especially to prevent and control the increasing prevalence of gastrointestinal diseases.

III. The negative impact of salt on the stomach lining and how it increases the risk of ulcers and cancer
The negative impact of salt on the stomach lining is a crucial aspect of gastrointestinal health. Consuming large amounts of salt can create a chain of harmful changes to the stomach lining, laying the foundation for an increased risk of ulcers and even cancer.
The main mechanism caused by salt is the disruption of the protective barrier of the stomach lining. This change not only increases the viscosity on the surface of the lining but also makes the lining more vulnerable to damage. Note that a vulnerable stomach lining increases the risk of developing ulcers and cancer.
Additionally, the increased concentration of gastrin in the blood, a hormone involved in regulating stomach acid, is also an important factor. High gastrin levels can lead to localized inflammation and increase the susceptibility to Helicobacter pylori (H.P) bacterial invasion, causing serious problems for the stomach lining.
In the acidic environment of the stomach, H.P bacteria can self-regulate, increasing the expression of the cancer-causing protein (cagA) in their genome. This increases the risk of developing gastrointestinal diseases, especially stomach cancer.
Understanding these mechanisms helps us see more clearly the link between salt and health problems of the stomach lining. At the same time, this information also highlights the importance of controlling salt intake in the daily diet to protect the overall health of the digestive system.

IV. The crucial role of H.P bacteria in causing damage and increasing cancer risk
The role of Helicobacter pylori (H.P) bacteria in causing damage to the stomach lining cannot be underestimated. Known as a significant factor in the development of digestive system health problems, H.P bacteria play a crucial role in increasing the risk of ulcers and even stomach cancer.
One of the main mechanisms of H.P bacteria is their ability to self-regulate in the acidic environment of the stomach. In this environment, the bacteria can increase the expression of the cancer-causing protein (cagA) in their genome. This not only enhances the bacteria’s invasion into the stomach lining but also increases the risk of developing gastrointestinal diseases, particularly stomach cancer.
Studies have shown that 80-90% of stomach and duodenal ulcer cases originate from H.P infection. In a salty environment, the bacteria can self-regulate and increase the expression of cancer-causing proteins in their genome, creating conditions for the development of precancerous lesions.
Understanding the role of H.P bacteria is important for recognizing the risk and consequences of this infection on the health of the stomach lining. At the same time, this information also emphasizes the importance of controlling and preventing the growth of H.P bacteria to reduce the risk of cancer and other issues related to the digestive system.

V. Research findings from international universities prove that increased dietary salt contributes to the risk of stomach cancer
Research findings from international universities clarify that increased dietary salt intake contributes significantly to the risk of developing stomach cancer. These studies not only confirm the link between salt intake and cancer risk but also provide precise details about the mechanism by which salt impacts the stomach lining.
According to information from leading universities worldwide, salt consumption exceeding the World Health Organization (WHO) recommendations has been strongly linked to an increased risk of stomach cancer. Research from Zhejiang University (China), Baylor College of Medicine, and Texas (USA) involving 6.3 million people demonstrated that an increase of 5g of salt per day can raise the risk of stomach cancer by up to 5%.
The mechanism by which salt contributes to stomach cancer risk is not limited to increasing blood gastrin levels and creating favorable conditions for Helicobacter pylori (H.P) bacteria growth. It also involves the formation of N-nitroso compounds in the acidic stomach environment, increasing the potential for metabolic changes and gene mutations, thereby raising the risk of developing gastrointestinal diseases.
These research findings not only prove the link between salt and stomach cancer but also raise awareness about the importance of controlling daily salt intake to reduce the risk of dangerous gastrointestinal diseases.

VI. Precancerous lesions and how reducing daily salt intake protects health
Precancerous lesions caused by increased daily salt intake are a significant issue requiring special attention. High salt consumption can create favorable conditions for the growth of Helicobacter pylori (H.P) bacteria and increase blood gastrin levels, both playing crucial roles in damaging the stomach lining and increasing the risk of developing gastrointestinal diseases, especially cancer.
Faced with these serious consequences, reducing daily salt intake becomes an important measure to protect health. The National Institute of Nutrition recommends a suitable salt intake for adults is less than 5g per day. For special groups such as pregnant and breastfeeding women, children, people with heart failure, chronic kidney disease patients, and hypertensive individuals, limiting salt is even more necessary.
Families can adopt various measures to reduce salt in their daily diet. Instead of using salt as the main seasoning, they can prioritize using herbs like garlic, thyme, rosemary, pepper, and chili powder to flavor food. For dishes requiring more seasoning, people can prepare them by steaming or boiling instead of braising, stewing, or roasting, gradually reducing the amount of salt and spices when seasoning food.
Reducing salt intake is not just about adjusting dishes but also involves food choices. Families can prioritize preparing fresh meals without using processed foods, especially those with naturally high salt content such as cured meats, sausages, ham, bacon, pickled vegetables, instant noodles, snacks, and salted roasted nuts.
Overall, reducing daily salt intake is not only a preventive measure but also a crucial way to lower the risk of precancerous lesions and protect the overall health of the digestive system.

VII. Practical measures and changes in eating habits to reduce salt intake, protect the digestive system, and maintain overall health
Practical measures and changes in eating habits can play a significant role in reducing salt intake, protecting the digestive system, and maintaining overall health.
- Choose low-salt foods: Opt for food products with low salt content or no added salt, especially when buying processed foods. Read nutrition labels carefully to understand the salt content in the product.
- Cook at home: Cooking at home allows you to control the amount of salt in your meals. Use herbs and salt-free spices as substitutes for salt during cooking.
- Limit salt-containing condiments: Avoid excessive use of fish sauce, soy sauce, and other high-salt condiments in meals. Instead, use fresh seasonings like garlic, chili, or salt-free spices.
- Gentle food preparation: Prioritize preparing food using methods like boiling, steaming, and grilling instead of braising, roasting, or frying, as these methods often require more salt.
- Control salt intake when eating out: When eating at restaurants or food establishments, request no added salt to your dishes. Also, utilize other spices like pepper and chili to add flavor.
- Use salt substitutes: If completely eliminating salt from the diet is not possible, use salt substitutes like potassium salt or mineral salt to reduce sodium intake.
- Gradually reduce salt: For those accustomed to high salt intake, gradually reducing daily salt consumption will help the body adapt better and avoid sudden salt deficiency.
- Consult a nutrition expert: If there are any concerns about diet or salt intake, discussing with a nutrition expert can provide suitable suggestions and advice based on individual health conditions.
