Below are a number of common nutrition myths I am asked about or hear about almost every day, and the truth that comes along with them (I'm a scientist, I like PROOF!)
Undoubtedly there will be people arguing against each point, however I base my comments upon the majority of upstanding and critiqed research, and what is well known in the professional community.
And as usual, ignore my type errors, as you know, it's certainly not my strength!
Targeted fat loss ‘stomach fat’ ‘thigh fat’ etc..
Simple. This is impossible. The only way to target fat loss is to physically remove it (ie. Liposuction.) Asides from this, fat loss, like fat gain is genetic. You simply can’t control it. The physiological mechanisms that choose where fat is placed is far more complicated than any supplement or exercise can possibly overcome. The closest thing can be done is to increase the muscle mass UNDER the fat, so it pushes through, giving the appearance of lean-ness, but this is very limited! Abs are made in the kitchen, not in the gym!
The organic craze has seen people assume organic foods to be healthier options as being certified organic means they have a level of pesticide below a set number. In New Zealand, most fruit and veg falls well below this number anyway, however the cost of organic certification is too high to make it worthwhile. The vitamin/mineral/goodness content in fresh, alike fruit is the same, be it organic or non-organic. In many situations, organic produce (particularly in supermarkets) has been sitting on the shelf longer than its non-organic counterpart (due to its higher price resulting in less demand) meaning a higher level of deterioration, and therefore a poorer quality item (though still more expensive)
For thousands of years our bodies have been totally adept at keeping away these evil toxins and stopping them from causing us harm, so we need to ask ourselves, why in the last 5 years has it become such a big deal? Yes, we are eating more processed junk, perhaps more contaminants, less pure and healthy foods, but our body is simply amazing. It is totally capable of dealing with this without ‘detox’ plans or supplements. And its not even called ‘detox’ – it’s simply an ongoing part of life, which millennia of evolution has experience in dealing with. If you are feeling a bit sluggish and have had a rough week and wish to speed along the process there is one thing which can help boost this – a little old thing called water!
The human body gets its energy from 4 sources – carbohydrate, fat, protein, and alcohol. This is how it is meant to work, and it’s had quite a bit of experience in the area. Excluding alcohol, most efficiently used source is carbohydrate. This is how we are built – choosing a low/no carb life won’t change this. If carbs aren’t available, fats and proteins will be broken down to get energy (not just fats) but this system is far from efficient – its slow, it produces more waste, and there are plenty of other health consequences which come with high fat intake. Yes there are different carbs, and yes this does make a difference, but that’s a story for another day.
