Food types based on way of eating!

Foods provide us with nutrition and are fuels for our daily activities and movements. This includes thinking and such mental activities as well.  Foods have varying amounts of carbohydrates, proteins, fats, vitamins, minerals, and trace metals. These are basic components of food and should be in right proportions in daily diet for health and prevention of diseases. Diseases result from shortage of food, excess of food, as well as deficiency and excess of any of the above components of food.  Also, read Ways of eating idlis  Humans learned to cook food after fire was made using stones. They also use sun for drying and fermenting of foods. Some vegetables and fruits are eaten raw such as in form of salads. Spices were discovered and cultivated and humans started using them in their foods to enhance flavour, taste, and aroma of foods.  Foods are cereals, pulses, vegetables, oils and fats, fruits, nuts etc. These can be made into different dishes by combining or alone.

MRNA covid-19 vaccine has opened up avenues for renewed interest and enthusiasm of use of mRNA in cancer cure

 Covid-19 vaccine has arrived amidst a mixed reaction. These vaccines from Pfizer-BioNTech and Moderna are messenger RNA. Another one from German Company CureVac NV is also on its way to be approved. There is more hope in these vaccines beyond control of covid. What are its future benefits?

mRNA vaccines and ordinary vaccines

Most vaccines are inactivated or attenuated viral parts which induce an immune response in the body that offers protection against the virus. They need cell cultures and chemicals. It is time-consuming with risk of contamination. But in case of mRNA, this process is skipped. Scientists determine which protein they want the host body to produce, analyze its amino acid sequence and see what instructions the mRNA must give. The process is faster and the mRNA is safe genetically.

The history of mRNA and its use

Research into mRNA began in the 1970s. But somehow after a decade of work on it it fell into the background. Money, time, efforts and patience went missing. Also some animal studies also led to fatal inflammation.

But somehow some scientists such as Hungarian-American Katalin Kariko continued work on this front and emerged victorious. She faced a lot of obstacles in her career and had salary cut and demotion. But nonetheless, she did not let her goal and focus to shift. She realized that uridine caused inflammation and changed this in the code with positive results. 

MRNA and cancer cure

Their research was mostly for use of mRNA against cancer. They used it to train the body to make immune cells against the target pathological antigen. This included viruses, other germs and cancer cells. The outcomes of studies in cancer was good and mRNA holds promise in treatment of cancers without affecting normal host cells. 

Not many investors were keen to put in money in this research. But now with the success of the mRNA vaccines against covid-19, renewed interest in them has happened. Hope for cancer cure is in the horizon!!!
