Vegetables are the most nutrient-dense, calorie-scare food that exists. For years, nutritionists have recommended five portions of fruit and vegetables a day in order to achieve peak health. As a result, generations of children were how carrots would help them see in the dark, but worst of all, denied dessert unless they finished eating the vegetables on their plate. Health fanatics also shoved vegetables into blenders to create “delicious” green-coloured, earth-tasting sludge – all in a bid to be healthy. But, following years of vegetable glorification, not all vegetables are as healthy as we thought. In fact, there are a number of vegetables that you could be better off avoiding altogether – especially if you’re looking to lose weight.
Some argue potatoes are in fact a starch, not a vegetable.
In addition to being tasty and versatile – chips, jackets, roasts – they are cheap and widely available.
But according to scientists at Harvard School of Health, they’re high in carbohydrates – the kind your body digests quickly, which causes blood sugar and insulin levels to spike and then drop.
Apparently, consuming one cup of potatoes, then has about the same effect on your blood sugar as a can of coke or a serving of jelly beans.
The scientists also linked potatoes to weight gain and diabetes.
In order to keep your blood sugar and weight from spiking, opt for potato alternatives, such as whole grains like brown rice and quinoa.
Botanically, aubergine or eggplant as it is also know, is actually a fruit.
But since most people recognise it as a vegetable, it joins this list.
Firm and hearty, aubergines are often used as a meat subsitute in kebabs, burgers, stirfrys and lots of vegetarian and Mediterrean dishes.
While it is tasty and filling, it’s not one of the healthiest vegetables.
For starters, they lack in protein and a large portion of the calories found in aubergine come from sugar.
To add to this, when aubergine is served in certain types of dishes, it’s spongy texture allows it to soak up fat and salt.
This bright yellow vegetable provides several health benefits; corn contains phytochemicals which can help promote vision health.
It is also full of nutrients like iron, potassium, and vitamin B.
But there are a number of reasons why you may want to limit your corn intake, particularly if weight loss is your goal.
A Harvard study discovered participants who ate more sweetcorn tended to pack on pounds.
The amount of weight gained from corn even exceeded the pounds put on from other starchy vegetables like potatoes and peas.
The reason sweetcorn consumption could lead to weight gain is because of its high glycemic index, which causes blood sugar levels to spike.
The increase in blood sugar can lead to cravings for unhealthy food – not unlike the spike that follows eating potatoes or a slice of white bread.
Most people consider avocados to be healthy since they are rich in nutrients and healthy fats.
Some people even believe the healthy fats in them are perfect for weight loss, others however, fear these fats may cause you to gain weight.
Avocados are a great source of several vitamins, minerals, but they are quite high in calories – around half an avocado contains around 160 calories.
And unlike most fruits and vegetables, avocados are relatively high in fat – about 15 percent by weight, and around 77 percent of an avocados calories come from the fat.
Avocados are one food source that can tip you over your daily calorie consumption – especially if you eat it in it’s guacamole form as you have no concept of how much avocado you consume.
Nutritionist Lisa Moskovitz comments: “While nutrient-density is more important than calorie-density for health, if you are trying to manage weight, eating excessive amounts of avocados, can lead to a surplus of energy that increases fat stores.
“Of course, this all depends on the person and what you are eating the rest of the day, as well.”
Celery juice is the latest diet and/or health craze that people start their day off and claim it helps their skin brighten and feel more energised.
No doubt, if you’ve ever been on a diet, someone at some point has said “You know, you burn more calories chewing celery than you get when you eat it”.
This isn’t necessarily true, a stick of celery has around 10 calories – and not much else.
It has some Vitamin C and K and antioxidants, but on the scale of healthfulness, celery doesn’t rank very high.
