Colon Cancer (or colorectal cancer) is the cancer of the large intestine, rectum and the colon. This is the last part of the digestive track of our bodies. Colon cancer is one of the most common types of cancer; however, the good news is that it is easily preventable.

Our diet plays a huge role in the prevention process! It is one of the major factors that can both cause or help prevent colon cancer.

Studies have linked high consumption of red and processed meats and low consumption of fibers to being one of the major causes of colon cancer symptoms.

In order to prevent colon cancer, you must know what food items to add and omit from your diet. Here is a short guide to help you out!

1. Limit Red Meat and Processed Meat

Best Food Choices to Prevent Colon Cancer

First and foremost, you must reduce the amount of red and processed meat you consume. Many studies have shown them to harm the intestine and increase the chances of colon cancer by up to 40%. Especially the fatty cuts. They trigger release of more bile acids into the digestive tracks, which in turn causes damage and promotes tumor growth. If you can’t completely avoid them, limit them to 2 or 3 servings per week (typically 2 ounce per servings).

2. Increase Fiber Intake

Best Food Choices to Prevent Colon Cancer

Fiber contains a short-chain fatty acid that stops the growth of cancer cells. Other than that, fiber is also known to improve the overall health and digestion. Nutritionists suggest eating about 15 grams of fiber each day. While there have been conflicting studies where fiber didn’t have any known benefits on the risk of colon cancer, however it is still beneficial to maintain fiber in your diets. You can get your daily fiber dose from brown rice, nuts, legumes, beans or even wholegrain cereals.

3. Take More Vitamin and Minerals

Best Food Choices to Prevent Colon Cancer

Both calcium and vitamin D can lower the chances of colon cancer by reducing the precancerous polyps. Other than that they also strengthen the bones. You can obtain calcium from sources like milk, cheese and salmon. While you can obtain Vitamin D from sources like sardines, egg yolks and above all, the sun!

Another mineral that reduces the chances of cancer is magnesium. Especially in people who are above 55 and overweight! Hence magnesium from beans, peanuts and spinach should also be added to your diet.

4. What Other Foods to Add To Your Diet

Best Food Choices to Prevent Colon Cancer

Ginger

It has been known to reduce colon inflammation, which is linked to tumor development. You can either consume ginger powder or eat fresh ginger daily.

Green Tea

Tea, especially white and green ones can reduce the risk of colon cancer by half. It helps in blocking polyp growth in the colon.

Black Raspberries

Potent antioxidants that are present in black raspberries have also been known to reduce the risk of cancer in the body.

Leafy Vegetables

Vegetables like broccoli, cauliflower, cabbage, kale, spinach and Brussels sprouts are known to reduce the risk of cancer as well. People who consume more vegetables are less likely to develop cancer!

Along with a stable and balanced diet, you need to stay physically active and quit smoking in order to minimize your chances of getting cancer!

Hopefully these tips will give you an insight in terms of what to eat and what not to eat to reduce the chances of contracting colon cancer.

colon cancer block by researchers

Researchers in the US have discovered that reducing the amount of the L-glutamine amino acid in the body can block the growth of colon cancer tumors in mice. The first clinical trials on humans are due to begin this summer.

L-glutamine is a non-essential amino acid found in eggs, meat, fish, dairy products, cereals and pulses. It is also found in raw spinach and parsley, as well as Asian miso. It’s sometimes recommended as a dietary supplement, notably for reducing intestinal permeability.

Recent research has established that cancerous tumors rely on L-glutamine to survive and grow.

In this latest study, scientists found that a subset of colorectal cancer cells containing a genetic mutation called PIK3CA–a commonly occurring mutation in cancer cells–were particularly high consumers of L-glutamine when growing.

When Professor Zhenghe John Wang and his team reduced the amount of L-glutamine available to these “mutant” cancer cells growing in laboratory dishes, the cells died.

This discovery, outlined in the journal Nature Communications, inspired the scientists to investigate the effects of depriving the cells of L-glutamine in mice with colorectal cancer tumors.

They found that when mice were given a compound to block the metabolism of L- glutamine, the tumors stopped growing. However, this effect was not seen in tumors that did not contain the PIK3CA mutation.

The findings, which are currently the subject of a patent application, could lead to the development of a new drug to suppress tumor growth.

The first clinical trials of an L-glutamine inhibitor in human patients with advanced stage colorectal cancer will begin this summer.

vitamin D deficiency

The word vitamin basically comes from Greek word vita and amines. Vita in Greek means “life”. Vitamins were so named as they are considered essential for life, and were originally thought to be amines. They are given exceptional importance as nutrients because they are not produced in the body and we are constantly in need of external sources of vitamins. Vitamins have innumerous functions in the body. They facilitate a lot of important reactions in the body as co-enzymes or co-transporters.

Vitamin D is one such important nutrient. Though it is categorized as a vitamin, you will find out why it is also considered a hormone in the body as you read through. Vitamin D is comprised of group of fat soluble compounds and essentially known to regulate mineral balance in the body. Previously its major role was thought to be regulation of bone health, but recent developments in medical science proved it has much bigger roles to play in the body.

Vitamin D Health Facts

As mentioned before, vitamin D has several functions to carry out in the body. Here are a few health facts about vitamin D.

  • We need 600 IU of vitamin D per day.
  • Pregnant, lactating and old females need around 800 IU/ per day as there is increased demand of vitamin D.
  • Normal levels of vitamin D in the body ensure normal development of bones, teeth and skeletal muscles in children and infants.
  • In adults, vitamin D maintains bone and teeth health and keeps them strong.
  • It regulates immune functions and maintains healthy immune inflammatory response.
  • Maintains normal muscle movement and function.
  • Efficient utilization and proper absorption of calcium and phosphorus.
  • Normal cell division.
  • Reduced risk of fractures.
  • Reduced risk of colorectal cancer.
  • Decreased risk of arthritis, osteoporosis and autoimmune responses.
  • Protection against diabetes type 1.
  • Regulates blood pressure and decreased risk of cardiovascular disease.
  • It can also help with certain type of depression known as seasonal affective disorder.

Recommended Intake and Reasons for Deficiency

Vitamin D recommended daily allowance is different for infants, adults, elderly and lactating and pregnant females. Around 10-15 micrograms are required by normal adult males and females. Elderly and pregnant females have higher requirement of about 10-20 micrograms. Patients suffering from long term illnesses have different requirement than normal adults this includes diabetics, cardiovascular and arthritis patients.

Although the daily requirement does not seem much and can be easily obtained from exposure to sun for about ten minutes, according to APMIS study 76% females and 23.8% males are vitamin D deficiency. Why is that so when the biggest source of vitamin D, the sun is free? The reasons can be anything between malabsorption, defective transportation and metabolism of vitamin D. This might be due to indoor jobs, darker skin pigmentation and lesser exposure to sunlight during winters.

Vitamin D either synthesized from sunlight in our skin, or absorbed from diet and then converted to its active form known as calcifediol and calcitriol in liver and kidneys respectively. If the enzymes involved in this reaction are defective, it is not possible for the body to utilize vitamin D which then leads to deficiency of vitamin D. Defective or inefficient vitamin D metabolism is more common in the elderly, one reason why they are at higher risk of vitamin D deficiency and skeletal disorders there on.

Some individuals who are not able to absorb vitamin D from digested food can also become vitamin D deficient. Patients suffering from severe bowel diseases such as Crohns disease, cystic fibrosis and celiac disease are more likely to lack vitamin D.

Obesity is another cause of vitamin D deficiency. Fat cells in the body extract vitamin D from the blood. Increased fat in the body would mean increased extraction of vitamin D from the blood which leads to low levels of vitamin D.

Diseases Vitamin D Deficiency Can Lead To

Vitamin D insufficiency is not just a problem in Pakistan and Asian countries but it s a problem spread globally. Vitamin D insufficiency is characterized by low levels of calcium in the body. Needless to say it can lead to bone weakness and skeletal disorder in the long run if not corrected immediately. Vitamin D is required to absorb calcium from the gut and reabsorb calcium from the kidneys this is how it maintains blood calcium level. When the body detects low blood calcium levels, calcium from the bones mobilized to compensate for it which leads to bone loss.

Children deficient in vitamin D suffer from irreversible childhood illness known as ‘rickets’. It is classically represented by bowed legs, frontal bossing and soft bones generally. Adults on the other hand suffer from what is known as ‘Osteoporosis’. Osteoporosis literally means brittle bones. They become weaker and weaker as more calcium is extracted from them to add to the blood. Weaker bones tend to fracture easily. This is one reason for high incident of long bone fracture in the elderly.  With reduced bone density, osteoporosis can happen to younger adults too.

Potential Sources of Vitamin D

As mentioned before, sun is the main source of vitamin D. Not many foods are rich in vitamin D. the richest natural sources of vitamin D is fish liver oils and fish meat such as sardines and herring. Other than that, no reliable plant source of vitamin D is known. This is one reason vegans are at higher risk of vitamin D insufficiency. Eggs, milk and butter are poor sources of vitamin D while fruits and nuts contain no vitamin D deficiency at all. This being stated, the most reliable source of vitamin D is fortified food products and supplements.

However, no supplements should be taken without prior consent of an experienced health provider. This is extremely important for individuals who are already taking medications for chronic illnesses.
