7 Kitchen Tricks


7 Kitchen Tricks You Should Know

Sometimes the simplest solutions are the best. Ironically, many of the following tricks for fixing common kitchen dilemmas aren’t widely known. But tuck them in your proverbial apron and you’ll have a far easier time resolving the following problems next time you face them:

1. How to Open Stubborn Pistachios
Pistachios are way too expensive to waste. Yet many of the delicious roasted nuts arrived in shells with little to no opening. Rather than attempting to bite them open or ruin your nails in a struggle you can’t win, next time try this foolproof method for opening stubborn shells: Take one half of a shell, stick it into even the littlest opening of an unopened pistachio, and turn the shell half like a key. The pistachio will pop right open!

2. How to Easily Remove Egg Shells Dropped into Eggs

It happens to all of us: You crack open an egg and a tiny piece of its shell falls into the bowl along with the raw egg. If you’ve tried to get it out with your finger or a spoon, you know the slippery dilemma you face. Next time, wet your finger with water before attempting to fish it out. You’ll be shocked at how easily it can be grabbed and eliminated.
3. How to Make Burnt Pots Look New Again
Considering how much a nice set of pots and pans costs, you’d expect them to be easy to clean. But even the best stainless steel cooking gear gets black with use and cooked-on remnants.  If you’ve attempted to scrub them clean you have probably succumbed to the notion that they will never glisten again. But, if you spray pots with oven cleaner and leave them for a couple of hours the grime will wipe right off! Likewise stainless kettles.

4. How to Refresh Crystallized Honey

You know that jar or bottle of honey that’s hardened and crystallized on your shelf?  It can easily be brought back to its easy-to-pour glory if you let it sit for 15 minutes in boiling water that has cooled for five minutes.

5. How to Soften Hardened Brown SugarBrown sugar hardens as its moisture evaporates over time in the cupboard. But you can easily re-moisturize it by placing the open sugar bag in a microwave with a cup of water next to it and zapping it on high for three minutes. Or you can place the sugar in a bowl, cover the sugar with a double layer of wet paper towels, and then cover the bowl with foil or plastic wrap and let it stand overnight.

6. How to Remove Stains from Wooden Cutting Boards
Can rings and wine and strawberries stains don’t help the style of your cutting board. To get out stains, try sprinkling the board with salt rubbing it with lemon. For more stubborn stains, try an abrasive antibacterial kitchen cleaner and scouring pad. For the toughest, reach for sandpaper! And of course wash thoroughly afterward!

7. How to Salvage Overripe Fruit

Fruit is expensive, yet it goes bad so quickly and easily. But you don’t need to toss your bruised or overripe bananas, peaches, or strawberries. The minute you see your fruit going bad, wash it, slice it, peel it (in the case of bananas) and freeze it in sealable bags. Then you have instant smoothie or pie makings anytime!

Ways to prevent cancer


20 Ways to prevent cancer

First, the good news: You probably won’t get cancer.
That is, if you have a healthy lifestyle. “As many as 70% of known causes of cancers are avoidable and related to lifestyle,” says Thomas A. Sellers, PhD, associate director for cancer prevention and control at Moffitt Cancer Center in Tampa. Still, since cancer is one of the top five lady killers, taking steps to eat a healthy diet, increase exercise, and avoid tobacco products is key; however, recent research has uncovered many small, surprising ways you can weave even more disease prevention into your everyday  life. Try these novel strategies and your risk of cancer could dwindle even more. 
1. Filter your tap water
You’ll reduce your exposure to known or suspected carcinogens and hormone-disrupting chemicals. A new report from the President’s Cancer Panel on how to reduce exposure to carcinogens suggests that home-filtered tap water is a safer bet than bottled water, whose quality often is not higher—and in some cases is worse—than that of municipal sources, according to a study by the Environmental Working Group. (Consumer Reports’ top picks for faucet-mounted filters: Culligan, Pur Vertical, and the Brita OPFF-100.) Store water in stainless steel or glass to avoid chemical contaminants such as BPA that can leach from plastic bottles.
2. Stop topping your gas tank
So say the EPA and the President’s Cancer Panel: Pumping one last squirt of gas into your car after the nozzle clicks off can spill fuel and foil the pump’s vapor recovery system, designed to keep toxic chemicals such as cancer-causing benzene out of the air, where they can come in contact with your skin  or get into your lungs.
3. Marinate meat before grilling
Processed, charred, and well-done meats can contain cancer-causing heterocyclic amines, which form when meat is seared at high temperatures, and polycyclic aromatic hydrocarbons, which get into food when it’s charcoal broiled. “The recommendation to cut down on grilled meat has really solid scientific evidence behind it,” says Cheryl Lyn Walker, PhD, a professor of carcinogenesis at the University of Texas M.D. Anderson Cancer Center. If you do grill, add rosemary and thyme to your favorite marinade and soak meat for at least an hour before cooking. The antioxidant-rich spices can cut HCAs by as much as 87%, according to research at Kansas State University.

4. Caffeinate every day
Java lovers who drank 5 or more cups of caffeinated coffee a day had a 40% decreased risk of brain cancer, compared with people who drank the least, in a 2010 British study. A 5-cup-a-day coffee habit reduces risks of oral and throat cancer almost as much. Researchers credit the caffeine: Decaf had no comparable effect. But coffee was a more potent protector against these cancers than tea, which the British researchers said also offered protection against brain cancer.

5. Water down your cancer risk
Drinking plenty of water and other liquids may reduce the risk of bladder cancer by diluting the concentration of cancer-causing agents in urine and helping to flush them through the bladder faster. Drink at least 8 cups of liquid a day, suggests the American Cancer Society.
6. Load up on really green greens
Next time you’re choosing salad fixings, reach for the darkest varieties. The chlorophyll that gives them their color is loaded with magnesium, which some large studies have found lowers the risk of colon cancer in women. “Magnesium affects signaling in cells, and without the right amount, cells may do things like divide and replicate when they shouldn’t,” says Walker. Just 1/2 cup of cooked spinach provides 75 mg of magnesium, 20% of the daily value.
7. Snack on Brazil nuts
They’re a stellar source of selenium, an antioxidant that lowers the risk of bladder cancer in women, according to research from Dartmouth Medical School. Other studies have found that people with high blood levels of selenium have lower rates of dying of lung cancer and colorectal cancer. Researchers think selenium not only protects cells from free radical damage but also may enhance immune function and suppress formation of blood vessels that nourish tumors.
8. Burn off your breast cancer risk
Moderate exercise such as brisk walking 2 hours a week cuts risk of breast cancer 18%. Regular workouts may lower your risks by helping you burn fat, which otherwise produces its own estrogen, a known contributor to breast cancer.
9. Skip the dry cleaner
A solvent known as perc (short for perchloroethylene) that’s used in traditional dry cleaning may cause liver and kidney cancers and leukemia, according to an EPA finding backed in early 2010 by the National Academies of Science. The main dangers are to workers who handle chemicals or treated clothes using older machines, although experts have not concluded that consumers are also at increased cancer risk. Less toxic alternatives: Hand-wash clothes with mild soap and air-dry them, spot cleaning if necessary with white vinegar.
10. Ask your doc about breast density
Women whose mammograms have revealed breast density readings of 75% or more have a breast cancer risk 4 to 5 times higher than that of women with low density scores, according to recent research. One theory is that denser breasts result from higher levels of estrogen—making exercise particularly important (see #8). “Shrinking your body fat also changes growth factors, signaling proteins such as adipokines and hormones like insulin in ways that tend to turn off cancer-promoting processes in cells,” Walker says.
11. Head off cell phone risks
Use your cell phone only for short calls or texts, or use a hands-free device that keeps the phone—and the radio frequency energy it emits—away from your head. The point is more to preempt any risk than to protect against a proven danger: Evidence that cell phones increase brain cancer risk is “neither consistent nor conclusive,” says the President’s Cancer Panel report. But a number of review studies suggest there’s a link.
12. Block skin cancer with color
Choosing your outdoor outfit wisely may help protect against skin cancer, say Spanish scientists. In their research, blue and red fabrics offered significantly better protection against the sun’s UV rays than white and yellow ones did. Don’t forget to put on a hat: Though melanoma can appear anywhere on the body, it’s more common in areas the sun hits, and researchers at the University of North Carolina at Chapel Hill have found that people with melanomas on the scalp or neck die at almost twice the rate of people with the cancer on other areas of the body.
Are You Over Exposed to the Sun?
13. Pick a doc with a past
Experience—lots of it—is critical when it comes to accurately reading mammograms. A study from the University of California, San Francisco, found that doctors with at least 25 years' experience were more accurate at interpreting images and less likely to give false positives. Ask about your radiologist's track record. If she is freshly minted or doesn't check a high volume of mammograms, get a second read from someone with more mileage.
14. Eat clean foods
The President’s Cancer Panel recommends buying meat free of antibiotics and added hormones, which are suspected of causing endocrine problems, including cancer. The report also advises that you purchase produce grown without pesticides and wash conventionally grown food thoroughly to remove residues. (The  foods with the most pesticides: celery, peaches, strawberries, apples, and blueberries. See the full list of dirtiest fruits and vegetables here.) “At least 40 known carcinogens are found in pesticides and we should absolutely try to reduce exposure,” Sellers says.

15. Read food labels for folic acid
The B vitamin, essential for women who may become or are pregnant to prevent birth defects, is a double-edged sword when it comes to cancer risk. Consuming too much of the synthetic form (not folate, found in leafy green veggies, orange juice, and other foods) has been linked to increased colon cancer risk, as well as higher lung cancer and prostate cancer risks. Rethink your multivitamin, especially if you eat a lot of cereal and fortified foods. A recent CDC study discovered that half of supplement users who took supplements with more than 400 mcg of folic acid exceeded 1,000 mcg per day of folic acid. Most supplements pack 400 mcg. Individual supplements (of vitamin D and calcium, for instance) may be a smarter choice for most women who aren’t thinking of having kids.
16. Up your calcium intake
Milk's main claim to fame may also help protect you from colon cancer. Those who took calcium faithfully for 4 years had a 36% reduction in the development of new precancerous colon polyps 5 years after the study had ended, revealed Dartmouth Medical School researchers. (They tracked 822 people who took either 1,200 mg of calcium every day or a placebo.) Though the study was not on milk itself, you can get the same amount of calcium in three 8-ounce glasses of fat-free milk, along with an 8-ounce serving of  yogurt or a 2- to 3-ounce serving of low-fat cheese daily.

17. Commit to whole grains
You know whole wheat is better for you than white bread. Here’s more proof why you should switch once and for all: If you eat a lot of things with a high glycemic load—a measurement of how quickly food raises your blood sugar—you may run a higher risk of colorectal cancer than women who eat low-glycemic-load foods, found a Harvard Medical School study involving 38,000 women. The problem eats are mostly white: white bread, pasta, potatoes, and sugary pastries. The low-glycemic-load stuff comes with fiber.
18. Pay attention to pain
If you’re experiencing a bloated belly, pelvic pain, and an urgent need to urinate, see your doctor. These symptoms may signal ovarian cancer, particularly if they're severe and frequent. Women and physicians often ignore these symptoms, and that's the very reason that this disease can be deadly. When caught early, before cancer has spread outside the ovary, the relative 5-year survival rate for ovarian cancer is a jaw-dropping 90 to 95%.
8 Mistakes That Make Pain Worse

19. Avoid unnecessary scans
CT scans are a great diagnostic tool, but they deliver much more radiation than x-rays and may be overused, says Barton Kamen, MD, PhD, chief medical officer for the Leukemia & Lymphoma Society. In fact, researchers suggest that one-third of CT scans could be unnecessary. High doses of radiation can trigger leukemia, so make sure scans are not repeated if you see multiple doctors, and ask if another test, such as an ultrasound or MRI, could substitute.
20. Drop 10 pounds
Being overweight or obese accounts for 20% of all cancer deaths among women and 14% among men, notes the American Cancer Society. (You're overweight if your body mass index is between 25 and 29.9; you're obese if it's 30 or more. Click here to gauge your BMI.) Plus, losing excess pounds reduces the body's production of female hormones, which may protect against breast cancer, endometrial cancer, and ovarian cancer. Even if you're not technically overweight, gaining just 10 pounds after the age of  30 increases your risk of developing breast, pancreatic, and cervical, among other cancers.
