First off, it’s worth highlighting that most people don’t even come close to getting as many vegetables as they should in their daily diet, so don’t use this as an excuse to avoid the greens you need. Think of this warning as inspiration to eat the full rainbow when it comes to your vegetables. “Broccoli is a superfood that is packed with potent antioxidants known to reduce the risk of cancer and heart disease, but when eaten in very large amounts, broccoli may lead to hypothyroidism (low thyroid),” say the Nutrition Twins, Lyssie and Tammy Lakatos Shames, authors of The Nutrition Twins’ Veggie Cure. “This is because they contain thiocyanates, which can make it difficult for your body to absorb iodine. If you’re someone who has dealt with thyroid issues in the past, be sure not to consume very large amounts of broccoli.”
The list of health experts and fitness influencers who swear by their morning lemon water is seemingly infinite. “It’s a very low-calorie, low-sugar beverage that encourages drinking,” explain The Nutrition Twins. “It helps you stay hydrated with its fresh flavour while also providing some immune-boosting vitamin C and antioxidants that may help to protect your cells from damage. However, if you drink a lot of lemon water, the acid from the lemon stays on your teeth and can damage your tooth enamel, which makes your teeth prone to cavities.” If you do drink a lot of lemon water, the twins recommend rinsing your mouth afterwards and drinking with a straw to minimise contact with your teeth.
Almond and plant-based milk
The problem with cow-milk alternatives, such as almond, oat, hemp, soy, coconut and rice milks, is that they’re often very processed and have lots of added sugars. In fact, these plant-based milks usually have little of the actual plant, says Keith-Thomas Ayoob, associate clinical professor at Albert Einstein College of Medicine. “A glass of the average almond milk, for example, only has about four almonds,” he says.
