Are superfoods really that super?
A scientist
debunks myths about them and tells you what’s good and bad
Many of us swallow the latest food fad without
thinking. Step forward nutritionist Dr Sarah Schenker, who has written a book
debunking many myths about grub. Here is her take on current ideas such as the
importance of breakfast and why most superfoods aren’t that super:
Bread — or more specifically
gluten — is bad for you
The trend for avoiding gluten has led to wild claims,
unsupported by medical evidence, and has hit public health due to the effect on
our intake of nutrients conventionally consumed in wheat products. Unless you
have a gluten intolerance/ medical condition then gluten in moderation has no
negative impact on the body.
You should cut all carbs to lose
weight
You will see dramatic weight loss but your body is
losing its glucose energy store, not fat. Carbohydrate is the body’s main
source of energy for physical activity and is needed by the brain. Extremely
low carb diets can lead to headaches and fatigue and, again, you are likely to
regain the weight you lost. Always include wholegrain foods in your diet, they
are an important source of vitamins, minerals and fibre.
Breafast is the most important
meal of the day
The “don’t skip breakfast” message is part of
government advice on eating well and stay healthy. In the first half of the
last century, breakfast would have been important for manual labourers but with
the growth in office work the need for a large breakfast is less necessary
since we burn fewer calories.
Magic of superfoods
There is no agreed scientific or legal definition of
a superfood or definitive scientific proof they will make you live longer, more
beautiful or protect you from illness. The notion that some foods are more
super than others is a nonsense. It is like claiming some letter of the
alphabet are more important than others. We need a range of foods to nourish
our bodies and keep them healthy.
All cals are not created equal
Differences in the energy lost during metabolism and
fermentation can influence the weight-loss effects of our diets. More energy is
used to fuel metabolism of protein. Some of the energy in carbohydrates is lost
through the production of gas. This may explain why weight loss is greater on a
high-protein, high- fibre diet compared with a different diet of equal
calories.
Detox your body with juice
Detox juices have no valid health claim. There is no
quick and easy remedy for weight loss or scientific evidence to support the
idea that fruit and vegetable juices increase detoxing.
Milk is bad for you
Milk and dairy provide vital nutrients important for
good health, including calcium, protein, iodine and vitamin B12. The protein in
milk will keep you feeling satisfied and fuller for longer — just what a snack
should do. Milk can naturally match pretty much any of meal-replacement shakes
and post-workout drinks available.
Eat fat, get fat
The success of any diet depends on how well people
stick to it. This depends on more than just the amount of fat consumed.
Different approaches will work for different people, especially in the long
term.
Caffeine dehydrates you
The opposite is true. Tea or coffee can act as a
low-calorie option for hydration.
