You stir-fry broccoli
Broccoli is a stir-fry recipe staple, but it shouldn’t be. One Chinese study found that stir-frying broccoli depletes its vitamin C content by 24 per cent, and also lowered the amount of chlorophyll, soluble protein and sugar. Another study in the Journal of Agricultural and Food Chemistry found that frying the florets caused a 67 per cent loss of carotenoids, which act as antioxidants, likely because of the high temperature. Steaming, on the other hand, allowed broccoli’s nutrients to remain nearly as intact as its natural raw state. Try steaming your broccoli and tossing it with the other stir-fry ingredients at the end, after removing the pan from the heat—it’ll still get coated with flavour and you won’t lose out.
You think dried and fresh herbs are the same
Dried herbs are always better than no herbs at all, but that doesn’t mean you should sprinkle dried parsley on that big bowl of pasta, says Ayesha Curry, chef and author of the cookbook, The Seasoned Life: Food, Family, Faith, and the Joy of Eating Well. Fresh herbs are more aromatic, so they pair perfectly with fresh items like fish or compound butter, and why they’re used to finish off a dish with a final punch of flavour, right at the end. Dried herbs work best for sauces and soups that cook for awhile, and as rubs for meat. “Dried herbs are great for meat rubs because you can mix them right in with the salt and other spices and get all those flavors going together,” she says. You can also use frozen herbs like Crush Cubes, which are flash frozen to preserve that fresh herb flavour.

You don’t soak your beans
If you’re using raw beans, failing to soak them could do more damage than just extending your time in the kitchen. “The longer you cook something, the greater the loss of vitamins and nutrients,” says Guy Crosby, PhD, CFS, a professor in the department of nutrition at Harvard T.H. Chan School of Public Health. “By soaking beans in a little salted water overnight, it allows their shells to tenderize and reduces the amount of time you need to boil them.” According to a review in the International Journal of Gastronomy and Food Science, soaking beans in salted water reduced cooking time by 53 per cent.

You only eat raw tomatoes
Salads and sandwiches shouldn’t be the only time you get your tomato fix. Cooking tomatoes actually makes them healthier. “Cooked tomatoes allow about four times more lycopene to be absorbed into your blood compared to raw,” says Crosby. Cooking it helps the powerful antioxidant lycopene separate from the proteins that bind it, allowing more to be released into the body, he says. Tomatoes are a potent cancer-fighting food.
You throw out all the hot pepper seeds
Even if you can’t take the heat, don’t throw every last hot pepper seed into the trash. “Seeds are not a bad thing! The flesh of hot peppers like jalapenos aren’t all that spicy; you have all that peppery flavour but not a lot of heat,” says Curry. Keep the seeds and add them in a few at a time until you reach your desired spiciness.

You don’t let onions and garlic rest
Your chopped onions and garlic shouldn’t go straight from the cutting board to the pan, no matter how much your eyes are tearing. Cancer-fighting compounds and flavonoids are activated when the cell walls are broken down by cutting or chopping; but as soon as they hit the heat, those powerful reactions stop, says Crosby. Letting the veggies sit for a few minutes will allow more of those healthy compounds to form, he says.
You don’t eat your pasta al dente
Limp pasta does more than break the cardinal rule of Italian cooking. Boiling pasta or other whole grains causes a significant amount of vitamins to get lost in the water, says Crosby. Eating your grains with a bit of bite will preserve some of the nutrients.
Here are four ways to perfect your pasta dishes.
You only eat broccoli florets
When you throw out broccoli or cauliflower stems, you’re tossing a boatload of nutrients in the trash, too. The stems actually contain more fibre, vitamin C, and calcium than the florets we favour.
You think boiled veggies are healthiest
“If you’re boiling vegetables, you’re boiling the nutrients right out, plus it’s easy to overcook them and turn to mush,” says Curry. “I believe in roasting in the oven; you’ll get much more flavour and a nice crunch.” One exception to the rule: carrots. A study in the Journal of Agricultural and Food Chemistry found that boiling carrots actually increased the amount of eye-healthy lutein and had no negative effect on beta-carotene content, also good for your eyes and skin.
You throw out the pineapple core
“You might not want to eat the core of a pineapple, but you can use it to get a little extra bromelain, which reduces inflammation,” says Elizabeth Shaw, MS, RDN, CLT, wellness consultant and author of shawsimpleswaps.com. Shaw suggests chopping the core and floating it in a pitcher of water. “I get a nice little hit of it, plus it helps me drink more water during the week,” she says. You can also cook it down, or if you don’t mind a little extra chewing, cut it into small chunks and eat raw.
You only eat the flesh of citruses
Get the biggest bang for your nutrient buck by using the rind of lemons, limes, and oranges, too. Citrus rinds contain more flavonoids and fibre than the juicy flesh; try gently grating the peel to add some zest to whatever you’re cooking.
You think garlic chunks add more flavour
“You’ll get much more flavour and aroma if you crush or mince garlic,” says Curry. And since garlic is extremely easy to burn, add it to the pan along with another ingredient, which gives it more room to breathe and not burn, she says. Whole garlic cloves also provide fewer antioxidants, which are activated with the act of chopping.
