Sodium and Cancer: Separating Fact from Fiction

Salt and cancer:

Let’s discuss one of those topics that often come up in the context of health, a subject filled with myths and misconceptions. It says you should refrain from salt in general to prevent cancer. Others, on the other hand, announce certain types of salt can indeed work as a medicine for cancer.

What’s true? Let’s step into what science says regarding sodium and cancer.

Why do we need sodium?

Before talking about cancer, we must learn about sodium. Sodium minerals help the human body to work efficiently. In simpler terms, think of sodium as tiny, which helps to move muscles and maintain water balance. In common sense, your daily supply of sodium is salt as sodium chloride, commonly known and used as table salt.

Your body needs sodium to work. Without it, you wouldn’t be able to think properly. Your body will not be able to contract muscles, or even keep the heart beat in a healthy way. In everyday situations, on the other hand, too much of a good thing may result in adversity.

Does excessive salt consumption lead to cancer?

This is a fundamental matter, and the answer is not a straightforward yes or no. About cancer, scientists have been working on the cause and effect of salt intake on the human body for several years. Here is what they found:

Stomach Cancer:There is also strong evidence that noshing on too much salt could increase your likelihood of stomach cancer. This happens more often in countries where people consume more salt-preserved foods. Consuming too much salt irritates the lining of your stomach over time, which can lead to changes that may turn into cancer.

Other Cancers:There is not enough evidence that salt directly causes most other types of cancer. However, large intakes of sodium may contribute to your risk for many different health conditions, including high blood pressure, which may also raise your risk for certain cancers.

Salt Alternatives and Cancer Risk

Substitute salts are an increasingly popular solution to meet public health objectives and are available in various forms such as potassium chloride, magnesium sulfate, and garlic salt.

What is the opinion of science regarding different kinds of salt and salt alternatives?

Sea Salt:The “healthier” variety that touts carries an equal amount of sodium as the old reliable table salt. It can’t guard against cancer, either.

Pink Himalayan Salt:It contains a few extra minerals, but no scientific data supports an advantage over other salts.

Potassium-based Salt:Replacements are good options if someone is trying to reduce sodium. Still, they should be used judiciously for a person suffering from kidney disease or is on one of those medications.

How does sodium impact cancer treatment?

If you are undergoing cancer treatment, your sodium intake may need a change. Here’s why:

Some cancer treatments interfere with your body’s handling of sodium. Some chemotherapy drugs cause you to retain more sodium than usual. Others cause you to lose sodium through vomiting or diarrhea.

Sometimes, this therapy interferes with the sense of taste in the head and neck. Foods that used to be salty now taste too salty or lack enough salt while trying to balance sodium in the diet. The needs can vary and be more or less depending on the case.

Therefore, it is prudent to discuss this with your healthcare provider.

What are some healthy ways to control sodium for the prevention of cancer?

Whatever your goal is to prevent cancer or navigate everyday life during or after cancer treatment, there are many simple ways to keep your sodium level healthy:

Sources of sodium in your daily diet, often hidden from us, are:

Processed and packaged foods
Restaurant & fast foods
Canned soups and vegetables
Packed and cured meats
Snacks such as chips and crackers
Condiments and sauces
Instant noodles and flavoring packets
Breakfast cereals

Healthy alternatives to reduce sodium intake:

Fresh fruits and vegetables
Pre-cooked homemade meals using fresh ingredients
Herbs and spices as flavorings
Lemon juice or vinegar to add taste
Fresh meats rather than processed ones
Unsalted nuts and seeds
Plain yogurt or milk
Whole grains with no additional seasoning

What is the role of sodium in the growth of cancer cells?

Scientific community has found a few pretty cool things about how sodium moves through cancer cells. Cancer cells differ from normal cells in certain ways, including how they handle sodium. Normal cells carefully regulate how much sodium comes in versus how much goes out. It gets lost so often in cancer cells and impacts their ability to grow and metastasize.

Some scientists are exploring whether sodium regulation will combat cancer. It would seek ways to use this difference between normal and cancer cells in creating new therapies. However, the level of this research is still at its nascent stage, so the concept of salt consumption doesn’t directly applicable.

Salt in diet reduction – can it prevent cancer recurrence?

This is a pertinent question for the cancer survivor since there is no direct evidence to show that merely reducing salt intake prevents the reappearance of cancer, but having a healthy lifestyle overall, such as monitoring sodium intake, could be helpful.

A balanced diet with moderate sodium levels supports your body’s healing and helps maintain good overall health. This is especially important after cancer treatment when your body needs healthy nutrition to recover and stay strong.

What do cancer experts recommend about sodium intake?

Doctors specializing in cancer generally have people follow the same sodium guidelines as they do for overall health.

For most adults, this limit is about 2,300 milligrams per about one teaspoon of salt daily. Not everyone, particularly those with a medical condition, will require less sodium. The general recommendation varies depending on one’s specific need. For example, your needs will differ once you receive a particular cancer treatment. You must sit with your healthcare team and discuss your needs.

How do you know if you take too much or too little sodium?

Your body will generally send signals if the sodium is too high or too low.

You could get thirsty, experience swollen joints, or sometimes have a headache when too much sodium is taken.
On the contrary, if you consume very little sodium, you might feel dizziness, fatigue, or confusion. In severe cases, either extreme can be dangerous.
These signals may be more complex to read during cancer treatment because the side effects of the treatment can mask them.

Monitor any changes in how you feel and share them with your healthcare team.

Bottom line

The relationship between sodium and cancer is complex. While high salt intake might increase the risk of some cancers like stomach cancer, it is a promoter of bodily functions. The key is to balance enough sodium to keep your body working correctly without getting too much.

Everyone is different, and something was needed differently during cancer treatment. What applies to one patient may not necessarily work for another. Work with your healthcare providers to establish how much sodium applies to your condition.

The most important thing is to make informed choices about your diet. Use reliable sources from trusted medical sources, and do not fall for anything that claims to be too good to be true. Whether you are trying to prevent cancer, in treatment, or a survivor, there is always a healthy balanced diet with the proper levels of sodium that can support everything else.
