Can Vitamin C Intake Prevent Cancer?

Vitamin C Ascorbic acid
Vitamin C for Cancer Prevention
Vitamin C (Ascorbic acid) is a water-soluble vitamin the human body needs to function well. It cannot be made by the body, and must be obtained from foods or other sources. Vitamin C is found in abundance in citrus fruits such as oranges, grapefruit, lemons, and in green leafy vegetables, tomatoes, potatoes, strawberries, red & green peppers. Many studies have shown a link between eating foods rich in vitamin C, such as fruits and vegetables, and a reduced risk of cancer.

According to The Critical Reviews in Food Science and Nutrition, the RDA of vitamin C should be 200 mg/day in an adult diet. The higher levels of vitamin C help prevent scurvy & reduce cases of the heart disease and cancer. Research studies in mice suggest that vitamin C can indeed inhibit the growth of some tumors.

Vitamin C is an antioxidant that helps block the action of free radicals, which can damage cells. This vitamin is said to enhance the immune system by stimulating the activities of white blood cells and anti-cancer agents. Some claim that the vitamin can prevent a variety of cancers from developing, including lung, prostate, bladder, breast, cervical, intestinal, esophageal, stomach, pancreatic, and salivary gland cancers, as well as leukemia and non-Hodgkin’s lymphoma.

Vitamin C is also said to prevent tumors from spreading, help the body heal after cancer surgery, enhance the effects of certain anti-cancer drugs, and reduce the toxic effects of other drugs used in chemotherapy. However, no randomized clinical trials have yet been done in humans to test the effect of Vitamin C supplements during radiation therapy or chemotherapy.

Many of these studies show people who eat foods to get a high level of vitamin C have about half as much cancer as those who have a low intake of these foods. The daily diet of an adult must include 5-9 daily servings of fruits and raw/ steam-cooked vegetables, with 6 ounce glass of orange juice. This would provide 200 mg of vitamin C daily. 

The intake of vitamin C on a daily basis poses no risk, but there is strong evidence that it would provide multiple & substantial health benefits.

Saffron Benefits for Cancer

Saffron, also known as Kesar, is cultivated in many countries including France, Turkey, Iran and India. It is popularly used as a food coloring and flavoring agent. The plant derived spice is made from the dried stigmas of the flowers of Crocus sativus

In folk and modern medicine, saffron has been used to treat depression, asthma, premenstrual syndrome, erectile dysfunction, macular degeneration and Alzheimer’s disease and insomnia. Experimental studies have revealed the role of saffron extracts and its components as cancer therapeutic agents as well.

Scientists have been able to identify various compounds in saffron that have anti-carcinogenic and anti-mutagenic properties. This has also been found that saffron can even delay certain types of tumor growth. Although the research is still in their early stages, but the broad range of activities of the plant extract on cancer cells encourages tapping the benefits of saffron in negating cancer.

Saffron has been shown to inhibit carcinogen-induced skin carcinoma in mice and to have cytotoxic action against human leukemia cell lines. Saffron also has been shown to cause cell death in liver cancer cells and carcinoma cells.

Saffron extract and its constituent, Crocin, have shown to significantly inhibit the growth of cancer cells while not ameliorating the normal cells. Crocetin, another natural carotenoid constituent of saffron, has shown significant potential as an anti-tumor agent in animal models and cell culture systems by enhancing anti-oxidative system, inhibiting nucleic acid synthesis, inducing apoptosis and hindering the growth factor signaling pathways.


Saffron extract has been shown to have dose-dependent inhibitory effects on the proliferation of human breast cancer cells. It has been proved to greatly inhibit chemotherapy-induced cellular DNA damage. It also was successful in delaying and preventing cancer in mice that were genetically predisposed to both soft tissue sarcoma and squamous cell carcinoma. Topical application of saffron also resulted in the inhibition of skin tumors. Even more recent research has revealed that saffron can also be utilized to help reduce side effects of chemotherapy drugs.

The other compounds of interest found in saffron are safranal, picrocrocin, and β-carotene that have also shown to have antioxidant, anti-inflammatory, radioprotective and anti-carcinogenic properties. In different cancers, it has been established that saffron extracts are dose dependent, and also dependent on the method of intake. Further studies are required to evaluate the safety and efficacy of saffron in cancer treatment.

Chemical Holi Colors can Cause Cancer! Make Organic Colours at Home


Holi is one of the major festivals of India, played with enthusiasm and blast of colors all over you. But when these chemically loaded colors come in contact with the skin, they tend to react and cause skin related problems such as allergies and sometimes, skin cancer! The colors available in market are extremely harmful and stink due to the presence of harsh chemicals in them.

Chemicals like Aluminium bromide (silver) and mercury sulphite (red) present in chemical colours can cause skin cancers. Copper Sulphate (Green) is said to cause eye allergy and temporary blindness; Lead Oxide (Black) can cause renal failure & learning disability; Chromium Iodide (Purple) can lead to bronchial asthma & allergies. After learning this, don’t you think that using natural colors is the safest option as they would go off easily, won’t harm your skin and won’t even cost you much.

Natural colours can be easily made at home. Here are a few ideas on how to create your own natural colours and stay away from harmful chemicals. So, get set to be drenched in colours, without any worries.


Beautiful and bright Yellow colour can be prepared at home by these simple methods.
  • Dry the rind of the Bael fruit and grind to obtain a yellow colored gulal.
  • Mix turmeric powder with double the quantity of gram flour (besan) to be used as yellow gulal. Besan can be substituted by wheat, rice or talcum powder. Turmeric can also be boiled in water to get deep yellow color. 
  • Soak marigold flowers in water and boil it to get yellow color solution. 
  • Dry the petals of flowers like yellow chrysanthemum, Amaltas or marigold and grind them to obtain different shades of yellow. Use this powder with gram flour or use it separately.

The Cancer Fighting Benefits of Rosemary

Rosemary (Rosmarinus Officinalis)
Rosemary (Rosmarinus Officinalis)
For centuries, culinary herbs have been the healthy seasonings and an abundant source of healing chemicals. A recent USDA study revealed that many popular herbs are a great source of natural antioxidants that help neutralize free radicals that are believed to be a major trigger to development of cancer.

In many parts of the world, rosemary (Rosmarinus officinalis, family Lamiaceae), is a common household plant that is used for many purposes including food flavoring, drink, and beverages, as well as cosmetic uses. Rosemary has also been used commercially as an antimicrobial food preservative for years, as it has a lot to offer as a nutritional supplement, especially in the prevention of some types of cancer, allergies, and the progression of Alzheimer’s disease.

Various studies have shown that rosemary can help prevent cancer and age-related skin damage. Rosemary contains more than two dozen antioxidants, including carnosic acid, one of the only antioxidants that deactivate free radicals through a multilevel cascade approach. In vitro studies have shown that as carnosic acid attacks free radicals, it is transformed into at least four other antioxidant compounds, each with the ability to neutralize additional free radicals.

The two key ingredients, caffeic acid and rosmarinic acid, found in rosemary, are potent antioxidant and anti-inflammatory agents that help protect the body's cells from free radical damage. Rich in carnosol, Rosemary has been found to detoxify substances that can initiate the breast-cancer process. The antioxidants in rosemary have also been found to prevent the development of cancer in human liver and bronchial cells.

Reduce Your Risk of Cancer: Follow These Tips

It is well accepted that your chances of developing cancer are affected by the lifestyle choices you make. So if you're concerned about cancer prevention, you must know that some simple changes in the lifestyle can make a big difference. In this post, learn about some of the useful cancer prevention tips:
Eat a Balanced Diet: Consuming a healthy diet might help reduce cancer risk. Eat plenty of fresh fruits and green vegetables. Limit your consumptions of saturated and saturated fats. High-fat diets tend to be higher in calories and might increase the risk of obesity, which may, in turn, increase cancer risk.
Keep a Check on Weight: Maintaining a healthy weight might lower the risk of various types of cancer, including cancer of the breast, prostate, lung, colon and kidney. Eating a balanced diet along with any form of regular exercise would not only make you fit, but also help to keep a check on weight gain. Include at least 30 minutes of physical activity in your daily routine to lower the risk of breast cancer and colon cancer.
Quit Tobacco consumption: Smoking has been linked to various types of cancer (including cancer of the lung, bladder, cervix and kidney). Chewing tobacco has been linked to cancer of the oral cavity and pancreas. Even if you don't use tobacco, exposure to passive smoking has the chances to increase the risk of lung cancer. Decision to stop consuming tobacco in any form is one of the most important steps you can take. If you need help quitting tobacco, ask your doctor, family and friends to help and support you.
Cut down on alcohol intake: Drinking alcohol can increase the risks of cancer of the breast, colon, lung, kidney and liver! The amount you consume and the length of time you have been drinking would increase the chances of inviting the disease.
Avoid direct Sun Exposure: Skin cancer is one of the most common kinds of cancer, and one of the most preventable! Try to avoid mid day sun when the sun’s rays are the strongest! When you're outdoors, stay in the shade as much as possible. Use sunglasses and a broad-rim hat for help. Wear clothes that cover much of your skin. Opt for bright or dark colors, which reflect more ultraviolet radiation than pastels or bleached cotton. Use generous amounts of sunscreen when you're outdoors, and reapply often.
Get Immunized: Cancer prevention includes protection from certain viral infections. Talk to your doctor about immunization against Hepatitis B and HPV.
Get Regular Self-exams and Screenings: Getting regular screening for cancers such as of the skin, colon, prostate, cervix and breast, can increase your chances of discovering cancer early, when treatment is most likely to be successful. Ask your doctor about the best cancer screening schedule for you.
Take cancer prevention into your own hands, starting today. The rewards will last a lifetime.

Turmeric For Cancer Prevention

Cancer Prevention

Turmeric (Curcuma longa), a reputed member of the family Zingiberaceae, is known for its multiple benefits ranging from medicines to food. It is extensively used as a food preservative, spice, and coloring agent in India, China and South-East Asia. Turmeric comes from the root of the Curcuma longa plant and has a tough brown skin and a deep orange flesh. This herb has a very good taste and aroma. Its flavor is peppery, warm and bitter while its fragrance is mild yet slightly reminiscent of orange and ginger, to which it is related.

The plant is also considered as auspicious and is a part of religious rituals. The rhizome is a rich source of carbohydrates, proteins, fats, minerals and essential oils. Curcumin, one of the components found in turmeric is anti inflammatory, antibacterial, antioxidant, chemopreventive, anticoagulant, anti-mutagenic, anticoagulant, diuretic, depurative, antidiabetic and antifungal in nature.

Curcumin has emerged as a potent multimodal cancer-preventing agent that targets various causative factors involved in cancer development. It intervenes at each stage in the complex sequence of cancer development, progression, invasion, and ultimately metastasis to healthy tissues. Curcumin also synergizes with standard chemotherapy drugs, helping to boost their efficacy and potentially reduce the dose of toxic chemotherapy products, minimizing needless harm and suffering for cancer patients.

The anti-inflammatory, antioxidant, and gene-regulating mechanisms of curcumin have yielded compelling results in combating a remarkably broad array of cancers, including those of the breast, uterus, cervix, prostate and GI tract. A burgeoning body of research demonstrates curcumin’s potential to counter cancers of the blood, brain, lung, and bladder as well. Curcumin is also emerging as a potentially effective intervention for pancreatic cancer- one of cancer’s most lethal and aggressive forms.

Turmeric is used as a spice in Indian kitchens, as well has various medicinal and therapeutic uses. Owing to its aroma and coloring property, powdered or grated form of turmeric is used in food preparations.

Garlic and Cancer Prevention

http://foodforcancerprevention.blogspot.in/
Garlic (Allium sativum)
A native to Central Asia, Garlic (Allium sativum) of the family Liliaceae has historically been prized for both culinary and medicinal use. It has the strongest flavor of all the alliums. A hardy perennial, garlic grows as bulbs, which are made up of cloves. Garlic is unique because of its high sulphur content.

In addition to this, garlic contains arginine, oligosaccharides, flavonoids and selenium, all of which are said to be beneficial to health. The characteristic odour and flavor of are garlic comes from sulphur compounds formed from allicin. The latter is the major precursor of garlic’s bioactive compounds, formed when garlic bulbs are chopped, crushed, or damaged. 

Several studies show an association between increased intake of garlic and reduced risk of certain cancers, including cancers of the stomach, colon, oesophagus, pancreas and breast. An analysis of data from various studiesshowed that the higher the amount of raw and cooked garlic consumed, the lower the risk of stomach and colorectal cancer.

Several compounds are involved in garlic's possible anticancer effects. Garlic contains allyl sulphur and other compounds that slow or prevent the growth of tumor cells. Allyl sulfur compounds, which occur naturally in garlic and onions, make cells vulnerable to the stress created by products of cell division. Because cancer cells divide very quickly, they generate more stressors than most normal cells. Thus, cancer cells are damaged by the presence of allyl sulphur compounds to a much greater extent than normal cells.

Protective effects from garlic may also arise from its antibacterial properties or from its ability to block the formation of cancer-causing substances, halt the activation of cancer-causing substances, enhance DNA repair, reduce cell proliferation, or induce cell death.

Although garlic has been used safely in cooking, excessive consumption can cause some side effects, in addition to strong breath and body odour. Ingestion of fresh garlic bulbs, extracts or oil on an empty stomach may occasionally cause heartburn, nausea, vomiting and diarrhea. Some studies suggest that garlic can lower blood sugar levels and can occasionally cause allergies.
