New research reveals additional clues to the mechanism behind tomatoes known protective effect against prostate cancer.
Investigators at all university of Missouri-Columbia, and colleagues demonstrated that FruHis, a carbohydrate derivative present in dehydrated tomato products, exerts this effect.
Laboratory studies showed that FruHis Protected against DNA damage. A combination of lycopene, an antioxidant in tomatoes that also protects against DNA damage, and FruHis caused a greater than 98% inhabitation of prostate cancer cell growth in vitro compared with single agents.
Fortification of foods and advice on sensible sun exposure are urgently needed.
Rickets became extremely rare in the United Kingdom, Europe and United States after it was realized that exposure to ultraviolet light was the major of vitamin D, and after the fortification of milk and other foods with vitamin D.
At least a billion people world wide are estimated to be vitamin D Deficient, mainly because of inadequate exposure to sunlight and inadequate fortification of food with vitamin D.
Human breast milk contains very little vitamin D and women with vitamin D Deficiency provide no vitamin D for their infant.
Vitamin D deficiency causes Secondary Hyperparathyroidism and increases destruction of the skeleton by precipitating on exacerbation osteropenia and osteoporosis. Raised parathyroid hormone concentration include phosphaturia and hypophospatemia, this causes a mineralization defect of the osteoid (osteomalacia). Unlike osteoporosis, which is painless disease, rickets and the adult counterpart osteomalacia can cause non-specific aches and pains in bones and muscles, and severe muscle weakness.
Vitamin D deficiency, or lack exposure to the sun have an increased risk of many risk of many cancers. Increasing the intake of vitamin D to 1000 IU a day reduces the risk of colorectal cancer and other deadly cancers by 30-50%. Vitamin D deficiency is also linked to cardiovascular disease.
One study found that the risk for the first cardiovascular event was 62% higher in people with Vitamin D deficiency.
Vitamin Deficiency has also been associated with autoimmune disease, infectious disease, and schizophrenia.
Serum calcium concentrations are usually normal in people with vitamin D deficiency and 1,25-dihydroxyvitamin D values are normal or raised.
The only way to know a person's vitamin D status to measure serum 25-hydroxyvitamin D concentrations. Aggressive treatment of vitamin D deficiency with 300 000 IU of intramuscular vitamin D daily. Vitamin D (50,000 IU) once a week for eight weeks will correct vitamin D deficiency. To maintain vitamin D sufficiency, 500,000 IU of vitamin D twice a month or 1000-2000 IU of vitamin D a day is usually sufficient. Vitamin D intoxication is an extremely rare.
Although the health benefits of vitamin D sufficiency are clear, awareness of dangers of vitamin D deficiency is lacking. People with vitamin D deficiency have no obvious symptoms until it is so severe that they develop osteomalacia; this is often misdiagnosed as fibromyalgia.

Whiplash is an acute injury of at least moderate intensity which causes a strain to the bones, muscles, nerves, tendons, and vertebral discs of the neck region. It is caused by a sudden, unexpected impact which jerks the head back and then forward causing the neck to snap out of alignment.
1. Traffic/stop light (‘traffic light disease’)
What are the symptoms?
Headaches/migraines, stiffness, neck pain, dizziness (nausea/vomiting), problems thinking or remembering, numbness and tingling (arms, face, shoulders), jaw pain, low back pain, hip pain, impaired vision.
- head restraint
- seat position
- seat belt height
are not adjusted correctly?
1) Body moves up – depending on angle of backrest and position of seat belt adjustor,..
2)... head jerks back…..
3) …pushing the head restraint down
What are the facts?
- even low speed accidents can cause significant injuries depending on where and how hard your car got hit, your position in the car, the position of your head, type of seat, position of the headrest, your pre-accident medical condition, and other things
- only 12% of persons who suffer from whiplash are symptom-free after 10 years
- Saab was the first to introduce an active protection system (SAHR); Volvo’s “Whiplash Protection Seating System” reduces acceleration forces on the neck by up to 50 %
- A study by Young et al. (2005) showed that 93% of all head restraints observed were sub-optimally positioned A L Young, B T Ragel, E Su, C N Mann, E H Frank: Assessing automobile head restraint positioning in Portland, Oregon; Injury Prevention 2005; 11: 97-101.
Adjust your seat position
Second is the arm position. The arms when fully extended should allow the wrists to rest at the top of the steering wheel. This allows the arms to be slightly bent at the elbow when fully extended for a turn. The purpose of this position is to prevent the arms from being overextended during turns (the shoulders should not need to lift from the seat back even to do a full arm crossover). Overextending the arms will cause them to tire quickly, and will cause the driver to lose sensitivity to the vibrations in the steering wheel
Third is the leg position. When any of the pedals are fully depressed with the ball of the foot on the pedal (not the toes), the leg should still be bent at the knee. This is to prevent overextension as described for the arms. Be sure that the knees are not against the underdash or steering column. In fact, there should be several inches room to prevent injury in event of a collision.
- Adjust head restraint – not only in your own car!
- Adjust seat position.
- Check seat belt adjustor position.
- Leave plenty of space (escape route) if you are the last car in a traffic jam – closely observe oncoming traffic in rear view mirror.
- Look up safety ratings before buying your next new or used car .
