Lemons and Cancer: Is Lemon a Cancer Cure?

With an increase in reporting by major media outlets discussing the many health benefits of various fruits and vegetables and how they play a part in fighting disease, you may have already heard that lemons cure cancer. While this isn’t completely factual, there have been several studies that purport to show a strong basis in using lemons for cancer treatment. It should also be noted that there are conflicting reports detailing that, while lemons and other citrus fruits do contain cancer-fighting properties, exactly how effective they are against particular types of cancer has yet to be accurately determined.


Health Benefits of Lemons for Cancer

In addition to the Vitamin C found in lemon juice, which is already a very well known alternative cancer treatment in its own right, the peel of the lemon also offers many health benefits, one of the most important being that lemon peel can help to eradicate toxins in your body. This may be why lemons for cancer are being studied and touted as a great remedy.

The connection between cancer and lemons isn’t something new; for decades, scientists have wondered, “Is lemon a cancer killer?” and have developed numerous studies to determine its validity.

Studies have revealed that lemon extract can successfully destroy malignant cells in a wide range of cancers, including breast cancer, colon cancer, and lung cancer. Several research studies also make the claim that lemons can destroy cancer much more effectively than chemotherapy, and in a safer and healthier manner. Additionally, the studies also show that lemon extract therapy only affects malignant cells, leaving healthy cells unharmed.

Additional health benefits of lemons include:

  • It is antibacterial
  • It is antiviral
  • It aids in digestion
  • It can be used to treat acne
  • It helps to regulate blood pressure
  • It fights against parasites and worms
  • It possesses antidepressant qualities
  • It helps to reduce stress and anxiety

Lemons for Cancer: How Much Do I Need to Consume?

So the question you may be asking yourself is, “Do lemons cure cancer and how much lemon do I need to consume on a daily basis?” Before answering this question, it must first be noted that while numerous studies have shown effectiveness in the consumption of lemons as a cancer killer, and is still undergoing a variety of testing and research to even come close to making that assertion.

What is known is that specific compounds found in lemons (and other citrus fruits such as oranges and grapefruit) known as flavonoids and limonoids may either stop the formation and growth of cancer cells, or will kill them outright. These studies have mainly been conducted on animals and in laboratory conditions using human breast cancer cells.

In Europe, a study was conducted with participants afflicted with various forms of cancer, in which they consumed 150 grams of citrus four or more times a week. The citrus proved effective in decreasing the risks of cancer by significant percentages, with the exception being breast cancer. However, an American study did show a decrease in the risk of breast cancer in participants using the same portions of citrus—so long as they did not previously undergo hormone replacement therapy.

When consuming citrus, it is also important to not just consume the juice, but also the pulp and the peel, and even the seeds when possible. Further research shows that 75 grams of citrus on a daily basis might be the optimal minimum intake for those wishing to reduce the risks of cancer.


How to Add Lemons to Your Daily Diet

Because lemons are very versatile in a wide variety of dishes, it can be very easy to ensure that you have lemon in at least one of your meals each day. At the very least, you can add lemon juice to water and drink a glass of lemon water every day. This ensures that you get a good dose of Vitamin C. However, because the peel of the lemon actually contains a much larger amount of important vitamins than the juice, it is recommended that you find ways to incorporate the peel into your daily diet as well.

One of the easiest ways to accomplish this is to either peel a lemon and place the peel in the freezer, or simply freeze a whole lemon. Then you can grate as needed, adding it to salads, soups, fish, chicken, rice, pasta, and many other dishes. You can add it to seltzer, to smoothies and other drinks.

    When using lemons for combating cancer–how much is 75 grams–150 grams. How does that translate to cups, tblspoons. quantities of lemons. does it help prostate cancer?

    • says

      The density of lemon juice is close to that of water, so 75 grams is about 75 ml (about 1/3 cup), and 150 g is about 150 ml (about 2/3 cup). So quite a lot of juice, number of lemons depends on how juicy the lemons are. As mentioned in the article, there is no proof to show that lemons assist cancer specifically, but its important to know that lemons deliver high doses of Vitamin C (no evidence again that orally taken Vitamin C will deliver the same benefits of IV Vitamin C), which has been shown to have overall activity against many forms of cancer, and secondly, they help stabilize the biological terrain of the body as well.

      Based on the article, using the entire lemon including peel and seeds, one would assume you weigh the entire lemon. Each whole lemon is approximately 135 grams….So eat a whole lemon a day and you would fall into the suggested guidelines…

    Lemons are a ph balancer they will adjust either way that your immune system needs. Cancer can not grow in an alkaline ph body. There fore it is good to drink lemon water each day in each glass of just plain tap water with no ice.

  3. Carole White says

    When using lemons or any citrus fruit for combating cancer, the amounts suggested of 75 – 150gms daily, can that amount be spread over the day?

    Can someone explain to me why putting a whole lemon in water is beneficial. I put my Ph meter in a glass of water that had a whole lemon in it for 12 hrs and it read 2.9. Now am i missing something. Don’t i need high alkaline body..over 7 to fight cancer. So how does this help.

    • says

      In a chemistry lab, adding acid to water makes it acidic, adding a base makes it basic – its a simple logic that we all understand. However, in the body, the answer to that question has several layers to it. I will try to be as simple and definitive as possible in my explanation.

      First of all, the question is not if lemon by itself is acidic – of course, it is. However, the body has a buffering pH self-adjusting mechanism that ensures that acids (or bases) consumed are neutralized and leveled to the body’s slightly alkaline pH level. This effect is demonstrated in how the body can transition from the incredibly acidic gastric juice in the stomach (pH 1.5 – 3.5) to a much more “neutral” intestine (pH from 6 in the duodenum to 7.4 further down the intestine). Too much acid? The body has a mechanism of flushing out excess acidity through the urine. Thus acidic urine is not necessarily reflective of an acidic body.

      The biggest gains from lemons do not come from its inherent pH. It comes from its natural ingredients – vitamin C, flavonoids, limonoids etc. that assist in reducing and reversing the cancer causing environment in the body. The fact is that most of the foods in our normal diets are devoid of similar beneficial ingredients, that allow cancerous processes such as inflammation occur unimpeded in the body. The high levels of sugars (in particular, fructose) in the body are a big culprit in creating the acidic environment we should really be worried about by inducing severe metabolic stress on the liver. High levels of uric acid and other pro-inflammatory products are formed in the body and the growth of pathogenic bacteria is promoted that excrete a toxic, acidic environment in their colonies.

      So the massive benefit of lemons is that it provides chronic disease fighting ingredients without a toxic overload of sugars. Many fruits contain highly beneficial chemicals, but they also have high levels of fructose which goes through much more harmful metabolic steps than glucose. It is significant to know that one lemon delivers only 0.6 grams of fructose, while a navel orange provides 6.1 grams and a banana is supplied with 7.1 grams. Limes, in fact, do not contain fructose at all.

      So is it accurate to say that lemons are alkalinizing? There are different schools of thought that would answer this question differently. However, this author’s view is that lemons do not add any acidic stress to the body allowing the body to maintain its physiologically stable, slightly alkaline pH, while at the same time adding powerful health promoting ingredients. In contrast, other foods add value to the process of acidity and decay, that in turn can lead to chronic diseases such as cancer. That is why lots of raw vegetables and low fructose content fruits (including lemons and limes) should be a staple in everyone’s diet.

    I have prostrate cancer with a PSA of 1 and 3+3 on other scale.I am on Hormone treatment for valid reasons If I can keep PSA around 1 or 2 I am going off the Hormone treatment as side effects are rough.Also the Hormone Treatment does not kill cancer and eventually stops working, without warnings.So I am going back on watchful waiting with a PSA every 90 days. SO anything that seems worthwhile like frozen lemon, one of my favorite fruits,is welcome
