We have al­ways been told that boil­ing our food is health­ier than fry­ing, but this re­search has proven oth­er­wise! The Aus­tralians sci­en­tists based their state­ment on one of the big­gest stud­ies on the health ef­fects of veg­eta­bles pub­lished so far. Study The re­searchers used data that had been gath­ered on more than one hun­dred and fifty thou­sand over 45s dur­ing the Aus­tralian 45 and Up Study. The re­searchers had fol­lowed the par­tic­i­pants for an av­er­age of 6.2 years. Good habits tend to be cu­mu­la­tive, and this was also the case for the par­tic­i­pants in the study. The men and women who ate large amounts of fruit and veg­eta­bles also scored well on other as­pects of a healthy life­style: they were more likely to sleep 7- 9 hours a day, have a healthy weight, be in a re­la­tion­ship and have a phys­i­cally ac­tive life­style. The re­searchers used sta­tis­ti­cal tech­niques to wipe out the ef­fect of other fac­tors as far as pos­si­ble, so that they were able to build up a pic­ture of the health ef­fect of fruit and veg on mor­tal­ity rates. When it comes down to it, mor­tal­ity fig­ures are the best in­di­ca­tor of health. Re­sults The more fruit the par­tic­i­pants ate ev­ery day, the less likely they were to die. That was not un­ex­pected. Veg­eta­bles had a sim­i­lar ef­fect. The higher the in­take of veg­eta­bles, the lower the mor­tal­ity rate. How­ever, the pos­i­tive ef­fect of veg­etable con­sump­tion was not very strong, and the trend was on the low side. That’s why the re­searchers looked again, this time sep­a­rat­ing out raw and cooked veg­etable con­sump­tion. Raw veg­eta­bles did not lower the mor­tal­ity rate, the Aus­tralians dis­cov­ered. The trend was shock­ingly low. Cooked veg­eta­bles – boiled, fried or steamed – did re­duce the mor­tal­ity rate. Conclusion“The as­so­ci­a­tion of raw ver­sus cooked veg­eta­bles in re­la­tion to mor­tal­ity re­quires fur­ther in­ves­ti­ga­tion”, the re­searchers wrote. The Aus­tralians were sur­prised to dis­cover that boiled, steamed and fried veg­eta­bles have a health­pro­mot­ing ef­fect while raw veg­eta­bles don’t. They aren’t sure how to ex­plain this. Per­haps, they sug­gested, all kinds of bioac­tive sub­stances in veg­eta­bles are more avail­able in cooked rather than in raw veg­eta­bles. De­spite this, the study con­firms what we al­ready know: fruit and veg­eta­bles are healthy. If you want to live as long as pos­si­ble and re­main healthy un­til a ripe old age, make sure that you eat plenty of fruit and veg­eta­bles.
