The biggest nutritional myths part 2
Posted by Aisling Murray on
This is a continuation of last week’s discussion on nutritional myths.
- Being overweight due to eating dairy and wheat that your body can’t process
I hear this theory a lot in my clinic and it is not true. If your body can’t process a food, it would suggest that food is not being metabolised and calories are not being absorbed, meaning a person would lose weight not gain it. There is no evidence to suggest that food intolerance causes weight gain, it can however cause bloating, skin irritations and cramps plus more. If you think you have a food intolerance, I suggest getting a food intolerance test done (available at Whelehans Pharmacy) and see a nutritionist for advice on how to change your diet.
- You can eat as much healthy food as you like
You can have too much of a good thing. True unrefined fresh foods are healthier for you but they still contain calories. The fat in foods like nuts, avocadoes and olive oil is better for the heart than fats like butter and margarine but all fats have the same amount of calories so less is more.
- Fresh foods are better than frozen
A lot of frozen foods are just as nutritious due to a process called flash freezing. The food is immediately frozen once picked meaning all the nutrients are retained. Fresh foods can lose their nutrient content during transportation, in this instance frozen food can be more ideal.
- Raw vegetables are better than cooked
In some cases certain vegetables have more benefits when cooked, for example, cooking carrots breaks down the tough cellular walls that encase the beta-carotene. Cooked spinach allows us to absorb more of the iron and calcium. Cooked tomatoes allow the body to absorb more lycopene (cancer fighting phytochemical).
- Microwaving reduces nutritional content of food
This theory is misguided as it isn’t the cooking method used but the length of time and temperature used in cooking which effects the nutrient content. Whether you use an oven or a steamer, the longer and hotter you cook the food the more heat and water sensitive nutrients are lost. Vitamin C and Thiamine (B vitamin) are particularly sensitive to cooking. As a microwave cooks’ food quicker it can actually minimise the loss of certain nutrients.
