Common diet mistakes to avoid -1

In our daily life, we commonly do some diet mistakes and should know how to avoid them. All of us know that eating good food or nutritious food can help us stay healthy. But do you know that the same nutritious food can make us unhealthy if we eat them in wrong proportions, wrong form or excess?  If your answer is no, then you should read about this.
Studies show that eating two or more uncooked egg- whites daily for several months can cause vitamin H (also called vitamin B7 or Biotin) deficiency.
This deficiency leads to hair-loss (include eyelashes and eyebrows), nails problem (i.e. may break, chip or flake easily), dermatitis (in the form of a scaly red rash around the eyes, nose and mouth, and genital area), conjunctivitis, depression, lethargy, hallucination, numbness and tingling, immune dysfunction, bacterial and fungal infections, decreased appetite and growth, etc.

Studies also show that, cooking and crushing tomatoes (canning process) and serving in oil-rich dishes (such as spaghetti sauce and pizza) greatly increases assimilation from the digestive tract into the bloodstream. Lycopene is fat-soluble, so the oil is said to help absorption. Lycopene in tomato paste is four times more bio-available than in fresh tomatoes. For this reason, tomato sauce is a preferable source as opposed to raw tomatoes. Processed tomato products such as pasteurized tomato juice, soup, sauce and ketchup contain the highest concentrations of bioavailable lycopene from tomato-based sources. Lycopene is not an essential nutrient for humans, but when absorbed from the stomach, lycopene is transported in the blood by various lipoproteins and accumulates in the liver, adrenal glands, and testes. Because preliminary research has shown an inverse correlation between consumption of tomatoes and cancer risk, lycopene has been considered a potential agent for prevention of some types of cancers. There are also cases of intolerance or allergic reaction to dietary lycopene, which may cause diarrhea, nausea, stomach- pain or cramps, gas, vomiting, and loss of appetite.
