VEGETABLES YOU SHOULD COOK – THE FACTS


 
 
SOME VEGEABLES ARE MORE HEALTHY COOKED THAN RAW
 
Some people try and maintain a raw diet as it is believed that delicate enzymes and vitamins, particularly vitamin C, can be destroyed when blasted with heat or boiling water.  So it may surprise many to learn that some vegetables are actually improved and better for our digestive systems if they are cooked. 
 
Mushrooms
 
We all know that if picking mushrooms in the wild you have to know exactly what you’re doing so as not to inadvertently ingest something deadly poisonous.  However, all mushrooms, even the safe and instantly recognisable ones that we see on the supermarket shelves, contain a potentially cancer inducing chemical.  This chemical to give it its proper name is called Hydrazines and although it is potentially hazardous the good news is that the chemical Hydrazines will be eliminated in the cooking process.  Eating raw mushrooms is therefore not ever recommended. 
 
Potatoes
 
Do you know not to store potatoes in the light?  Most people wouldn’t think about eating a raw potato as it’s fairly unpalatable, which is good because they contain Glycoalkaloids that are harmful.  All potato production contains a certain level of this compound but the more time they are exposed to light the more the glycoalkaloids build up, so it’s best to keep them out of the vegetable rack and inside the fridge.  Cooking doesn’t entirely eliminate this chemical compound but it certainly aids in reducing its toxicity.   
 
Sweet Potatoes
 
You may think that the same compound would be found in sweet potatoes and so the same rules apply as to normal potatoes, but it’s a different enzyme here that reacts badly within our stomach and inhibits digestion if eaten raw.  It's unlikely anyway that anyone would want to eat a raw sweet potato.  This occurring enzyme is not poisonous and the sweet potato doesn't react  in the same way as ordinary potatoes as although similar in appearance it's actually a different family (Convolvulaceae).  You can also eat the leaves of sweet potatoes, which are highly nutritious and are eaten in some other societies.  Sweet potatoes also contain levels of beta carotene which is found in carrots and other orange or red vegetables, (see below).
 
Tomatoes
 
This salad favourite, often grown at home by many and eaten raw almost daily in salads, contains an antioxidant called Lycopene which you may have noticed receiving a lot of press attention recently for its much lauded health benefits.  These encouraging findings reveal that Lycopene can be helpful to reduce heart disease and even goes so far as to suggest it’s a weapon in the fight against cancer.  However, when you eat tomatoes raw you do not consume the antioxidant levels to the same degree as you’ll derive from a cooked tomato.  As research proves that cooking the tomato actually unlocks the Lycopene thereby releasing it in a higher dose for use within the body.  Ketchup for instance has highly beneficial quantities of useful antioxidants, but if you want to enjoy ketchups and chutneys why not experiment with making your own, that way you can better control the ingredients and reduce any negative elements such as high proportions of sugar and salt.  
 
Carrots
 
Do carrots help you see in the dark?  Well apparently so.  There is some truth to this urban myth as carrots contain an antioxidant, beta-carotene, a hydrocarbon, that does aid vision and which our bodies use to convert into vitamin A.  Beta-carotene also supports a healthy immune system and again has shown to be an effective deterrent against breast cancer.  Like the Lycopene in tomatoes, heat applied through cooking will release a higher dose than that available in its raw state.
