Food Therapy - Strawberries and Oral cancer

Strawberry is a genius of Fragaria × ananassa belongs to the family Roseaceae. They have been grown all over the world with suitable climate for commercial profits and for health benefits.
Oral cancer is any malignant cell growth in the tissue located in the oral cavity, including the tissue of the lips or the tongue, cheek lining, floor of the mouth, gums (gingiva) and the roof of the mouth (palate).


Nutrients and Chemicals constituents

1. Carbohydrate
2. Dietary fiber
3. Omega 3 fatty acid
4. Calcium
5. Iron
6. Magnesium
7. Phosphorus
8. Potassium
9. Sodium
10. Zinc
11. Copper
12. Manganese
13. Selenium
14. Vitamin C
15. Thiamin
16. Niacin
17. Pantothenic acid
18. Vitamin B-6
19. Folate
20. Vitamin B-12
21. Vitamin A
22. Vitamin E
23. Vitamin K
24. Etc. 

The major chemical compounds include anthocyanin and ellagitannins and p-Hydroxybenzoic acid, p-coumaric acid, ellagic acid, cyanidin-3-glucoside, pelargonidin-3-glucoside, kaempferol, quercetin, and myricetin

The benefits
Strawberries contain multiple phenolic compounds, which are thought to contribute to their biological properties in reducing the risk of cancer and chronic diseases. the anthocyanins, the major constituent found in strawberry were the most potent antioxidants in the inhibition of  the growth of human oral (CAL-27, KB) cancer cells with different sensitivities observed between cell lines. Other chemical constituents such as anthocyanins, flavonols, flavanols, ellagitannins, gallotannins, proanthocyanidins, and phenolic acids, are also found to be potent in inhibition of oral cancer in increasing concentration manner.

The Side effects
1. Some people may beexperience anaphylactoid reaction to the consumption of strawberries

2. Oxalation
Oxalates in high concentration can cause problem for people with kidney diseases.
3. Etc.
