18 Secrets to Make Your Food Healthier Without Even Trying

Experts show how to effortlessly unlock the powers in common foods to help fight disease, lose weight, and more.

Refrigerate cooked potatoes

The cooling process turns high-glycemic vegetables into low- or moderate-glycemic vegetables, and that transformation helps keep your blood sugar levels more stable. (Beware of these sneaky things that raise your blood sugar.) Even if you reheat the veggies, this trick works. As a bonus, cooking with extra-virgin olive oil helps keep the veggies from slowing down your metabolism. Turn every meal into a healthy one by making these healthy cooking recipes a regular part of your diet.

Thaw your frozen berries in the microwave

Frozen fruit and veggies have been shown to be better for you than fresh out-of-season produce, since they are picked and frozen when their nutrition is at their peak. Also: Berries are your fiber friends: Ounce per ounce, there is more fiber in raspberries than bran cereals!

Prepare your salad the day before you eat it

On the other hand, these salad mistakes will actually make your meal less healthy. Shred clean greens with your fingers, put in a plastic bag with a paper towel to absorb extra moisture, and keep in the fridge till the next day. Then toss with toppings.

Beta-carotene, a precursor to vitamin A, contains powerful antioxidant functions that can boost your immune system, improve eye health, and lower your risk of heart disease. However, taking beta-carotene as a supplement—as opposed to getting it through vegetables—could increase your risk of lung cancer, which is why it's one of the 8 vitamins that are a total waste of money.

Cook carrots whole

And when cooked whole, they have 25 percent more falcarinol, a cancer-fighting compound, than carrots that have been chopped beforehand. Chomping on carrots as a snack can also prevent you from overeating, thanks to their fiber content. Check out more fruits and veggies that will always fill you up.

Use a salad fork to get holes all over.

Thoroughly chew your grapefruit

Throw a chile into a corn dish

As an added bonus, one raw green chile has double the amount of vitamin C found in an orange. Check out more foods you'd never guess have more vitamin C than oranges.

Buy canned tomatoes over fresh

tomatoesKarpenkovDenis/shutterstockAll tomatoes have cancer-fighting properties, but the most nutritious tomatoes in the supermarket aren't in the produce aisle! Processed tomatoes are the richest known source of lycopene, because of their concentrated state. When buying fresh, look for smaller size and deeper color; you'll get more nutrients. If you have a choice, deep red tomatoes have more antioxidants than yellow, gold, or green tomatoes. These are the 12 cancer-fighting foods you should be eating every day.

Bake with avocados instead of butter

Not ripe? No problem! Use this trick to ripen your avocados in 10 minutes.

Choose dark chocolate over milk chocolate

Make leafy greens more potent with a squeeze of lemon

We all need the health benefits from leafy greens, but it's especially important for vegetarians to access the nutrients they're missing from a meatless diet, including iron. Frances Diaz, RD of FITzee Foods shares,"Vegetables like spinach, broccoli, and kale contain lots of iron, but it’s in an indigestible form. So adding vitamin C to these foods will help your body break it down in to a form that is more easily absorbed by our bodies." Try adding lemon, lime, or orange.

Store asparagus like roses

AsparagusDusanZidar/ShutterstockStore asparagus upright in a small vase or bowl in your fridge to keep its metabolic activity going, and you'll prevent spoilage while keeping the veggies fresher and more antioxidant-rich. Follow these tips to keep your fruits and veggies fresh longer.

Boil and drain your Swiss chard, beet tops, and spinach before eating

swisschardAzdora/ShutterstockDoing so frees up acids that are linked to certain types of kidney stones formation, according to nutritionist Nicolette M. Pace, MS, RD. These are the warning signs of kidney stones you need to look out for.

Rub the skin of kumquats before you pop them in your mouth

kumquatvirtustudio/shutterstockIt's worth finding kumquats to try this out; limonene has been shown in studies to have anti-cancer effects. Aim for about five to get a good dose of vitamin C, carotenes, and lutein; and eat them whole (peel and all) to reap their full nutritional benefits.

Let your lentils sprout

lentilsNalaphotos/ShutterstockWhen legumes like beans and lentils sprout, the grain’s starchiness lowers, and the protein content rises. In fact, lentils contain all essential amino acids, making them one of the few complete protein foods that aren't meat. This process not only makes them more nutritious, but also appears to make them more easily digested.

Make beets bite size before cooking

beetsAfricaStudio/shutterstockCutting beets into chunks or cooking the smallest ones you can find will aid in keeping their nutrient levels high, since you can reduce cook time (the rich betalin color is highly susceptible to nutrient losses with extended exposure to heat). Those nutrients can reduce your risk of dementia and heart disease. Try for 15 minutes when steaming, and 45 max when roasting.
