Raw Or Cooked Vegetables Better?
You may have wondered about whether it is better to eat your vegetables raw or cooked. Is eating them raw really better and healthier? Does cooking destroy all the nutrients?
Some of us like to munch a carrot and tomatoes in a salad is quite tasty.
Most people believe that raw food is best and that cooking destroys whatever nutritional value it has. In most cases this would be true but it may be healthier to eat some vegetables cooked rather than raw.

Raw Carrots Or Cooked Carrots Better?
Cooking breaks down the tough cellular walls
Carrots are one of the best sources of beta-carotene. The body converts beta- carotene into Vitamin A which is important in reproduction, vision, bone growth and also regulating the immune system. So if we are to eat more carrots - do we eat them raw or cooked?
It has been found that cooking carrots actually increases the level of beta-carotene. The reason is that raw carrots have tough cellular walls. Cooking carrots will dissolve the walls and free the nutrients to be available to the body. An experiment carried out at the Institute of Food Research in 2009 showed that the body can absorb about 5% of the beta carotene from a single carrot, whereas when it is boiled, the carrot released 60% and blended and then boiled a whopping 90%!!
So next time try some boiled carrots. Same goes for zucchini and broccoli.

Cooked Tomatoes have higher antioxidant power
Tomatoes is a vegetable that most of us enjoy both raw and cooked. We have it in our salads and sandwiches but we also have it in our ketchup, pizzas, etc.
Tomatoes are a good source of lycopene, the phytonutrient which gives the tomato its red color and also its antioxidant power. A report in Scientific American suggests that simply cooking it will increase the antioxidant power of lycopene. Heating changes the chemical structure of lycopene to make it more bioavailable.
Studies have suggested that lycpopene may help against cancer particularly prostate cancer. Lycopene also has antibacterial and antifungal properties. It can help to reduce inflammation of gums and Candida albicans or yeast infections.
Raw Vegetables To Avoid
Avoid eating cruciferous vegetables raw as they contain chemicals which block the production of the thyroid hormone. This would especially affect those trying to lose weight.
Some of these vegetables include broccoli, kale, cauliflower, bak choy, cabbage, turnip, brussels sprouts, turnip and radish. Cooking reduces these thyroid affecting substances by two thirds.
It is fine to enjoy a bowl of coleslaw once a while but try not to make a habit of eating it raw.

2. Amount of water - Use minimal amount of water to cook food.
3. Surface area of vegetables - More nutrients are leached with greater surface area. So the more thinly sliced vegetable will lose more nutrients compared to chunky cuts.
4. Method of cooking - Boiling and steaming your vegetables are better in preserving the antioxidants especially the carotenoids. Deep fried foods are sources of free radicals as the oil is continuously oxidized when heated up to very high temperatures.
