Pesticides, Can we avoid them?
by: anna maria volpi
Why, unfortunately, just washing vegetables is not enough to ensure produce clean enough for consumption We all ingest lots of chemicals, one way or another. We breathe them, we drink them, and we eat them.
The most troublesome are pesticides in produce. It makes me uncomfortable to think that while we are eating fruits and vegetables in reality we are also ingesting poisons that can accumulate in our bodies and make us very sick.
This is food that supposes to be healthy and good for us! Even if the most toxic chemicals have already been banned for use in agriculture, pesticides in general are poisons designed to kill insects, weed, small rodents and other pests.
The long time effects of these poisons on people are not completely known. Even the minimal risk with these pollutants is too much, when we think we may expose children. We should try to do every effort to minimize our intake of these adverse chemicals.
Education is the key. Knowing which produce contain more pollutants can help us make the right choices, avoiding the most contaminated fruits and vegetables and eating the least polluted, or buy organic instead.
In simulation of consumers eating habits has been demonstrated that changing a little bit the eating practices can lower considerably the ingestion of pesticides. The results of an investigation on pesticides in produce by the USDA Pesticide Data Program, show that fruits topped the list of the consistently most contaminated produce, with eight of the 12 most polluted foods.
The dirty dozen are: Apples, Bell Peppers, Celery, Cherries, Imported Grapes, Nectarines, Peaches, Pears, Potatoes, Red Raspberries, Spinach, and Strawberries.
You don’t like broccoli? Too bad because they are among those least contaminated. In fact the 12 least polluted produce are: Asparagus, Avocados, Bananas, Broccoli, Cauliflower, Sweet Corn, Kiwi, Mangos, Onions, Papaya, Pineapples, and Sweet Peas. Can washing of produce help get rid of pesticides? Not really.
The fruits and vegetables tested by the USDA PDP are “prepared emulating the practices of the average consumer” before testing for pesticides.
That is: “(1) apples are washed with stems and cores removed; (2) asparagus and spinach have inedible portions removed and are washed; (3) cantaloupes are cut in half and seed and rinds are removed; […] and (9) tomatoes are washed and stems removed”.
Washing before consuming is highly recommended because helps decrease the pesticide residues present on the surface of the vegetables, but the majorities of pollutants are absorbed into the plant and can’t be just washed away.
Some pesticides are specifically created to stick to the surface of the crops and they don’t come out by washing. Peeling can help eliminating some of the chemicals but not all, and a lot of important substances will be discarded with the skin.
So, on one hand we have to eat plenty of fruit and vegetables for a healthy diet, and on the other hand we have to reduce as much a possible the intake of pesticides.
What to do if you are unconvinced by the claims of the chemical companies that certain levels of pesticides are not dangerous? We have very few options to defend ourselves: (1) Wash all vegetables and fruit very well; (2) Change eating habits in order to consume more of the produce with low pollutants; (3) Consume a diet as varied as possible; (4) Buy organic foods.

Eat Your Veggies! Simple Cooking Methods
Eat your Veggies! Simple Cooking Methods
Vegetables add colour, taste, texture and bulk to our daily diet. There are dozens of different vegetables that can be prepared in literally hundreds of ways. So what's best?
There is no best. The thing to do is to eat your vegetables, lots of them, everyday in a wide variety of ways and stop worrying about the preparation methods. Variety is the key...
Raw
Many vegetables taste fabulous just the way they are straight out of the garden. Lettuce, tomato, celery, cabbage, onion, radish, carrot are obvious choices here. But they are just as likely to find themselves next to chopped up broccoli, cauliflower, peas, beans and zucchini on a starter platter with dips. Wash 'em, chop 'em and eat 'em. Oh, yeah, you could also make a salad!
Steamed
Steaming heats the vegetable and softens it's texture. It's gentler than boiling and allows the vegetable to maintain it's colour if not overdone. Use a stainless steel steamer that will fit into most good size sauce pans. Make sure you use a pan with a tight fitting lid. There should be enough water to just touch the bottom of the steamer. Water should be simmering the whole time the vegetables are being cooked.
Boiling
Boiling vegetables is really going out of fashion, but it's a legitimate preparation method! The big concern is loss of nutrients. All cooking methods result in the loss of some goodness from the vegetables. If boiling, try to find a way to use the water the vegetables have been boiled in (i.e. to make a gravy or sauce) to bring those nutrients back to the table. Vegetables should be barely covered with water. Bring the water to a boil (covered) then slow to a simmer until vegetables are tender.
Microwave
Very popular for vegetables as it retains colour, flavour and nutrients. Trial and error will be your guide with microwaving as there are plenty of variables involved. However, a few guidelines will help...The more food you put into the oven, the longer it will take to cook. Underestimate your cooking time rather than overestimate. Undercooked food can be cooked some more. Over-cooked food is ruined. Food straight from the fridge will take longer to cook than that at room temperature. All food continues to cook after it has been removed from the microwave oven. It is part of the cooking process and should be taken into account to prevent over-cooking.
Stir Fry
Very rapid method of quick frying vegetables, meat (optional) and sauces in one pan to make a meal. Primarily associated with Asian cooking. The key to doing this well is preparation. All items to be cooked should be chopped to a size that will allow them to cook quickly in the wok. It is also important that the wok is heated to a high, consistent temperature throughout. Vegetables maintain their colour and crispness with this sort of cooking (if not overdone).
Baking
Brilliant! Especially for those 'root' vegetables like potatoes, turnip, carrot and beetroot. Chop into similar size pieces, brush lightly with olive oil and put in a hot oven to roast. Size of the pieces will determine the cooking time but expect at least 40 minutes. Outside is chewy, inside is moist and fluffy. Dress with sour cream and chives. Yum!
Barbeque
Does anything scream summer like the word barbeque? Love a barbeque. This is primarily open flame cooking, so could apply to a campfire as well. Cooking outside just changes everything about food. You'll need foil, fire and fresh veggies. Grease your foil, chop your veggies and put the closed packages on the grill. Be adventurous, it's really hard to mess this up!
