1 . Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.

Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.

2 . By now, most people know they should be eating more vegetables. But are there ways to get more from the vegetables you already eat? A research shows that when it comes to vegetables, it’s not only how much we eat, but also how we prepare them, that decides the vitamins and other nutrients that enter our body.

Many studies show that people who eat lots of vegetables have less heart disease, and eye problems and even cancer. But raw vegetables are not always best. The researchers found that 198 Germans who eat raw food were short of lycopene, the matter found in tomatoes and other red vegetables. “There is an idea that raw foods are always going to be better,” says Steven K. Clinton, a professor at Ohi o State University. “For fruits and vegetables, sometimes a little bit of cooking can be helpful.”

A number of factors decide how the vegetables do good to people’s health before they reach the table, including where and how they were grown and stored before being bought. No single cooking way is best. Some nutrients are easily lost in cooking if they are cooked in different ways.

Vitamins C and B are often lost. In January, another report said that boiling was better for carrots than frying or serving them raw. Frying was the worst way to cook.

What cooked with the vegetables can also be important? When the vegetables were cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them. Putting on some other things that make it taste better—a little salt—can make the food taste better.

5 . Advice for Cooking on a Tight Schedule

From my experience, there are three main reasons why people don’t cook more often: ability, money, and time.

    1    Money is a topic that I’ll talk about another day. So today I want to give you some advice about how to make the most of the time in the kitchen. Here are three tips for great cooking on a tight schedule:

Think ahead. I usually think cooking is a pain when I’m already hungry and there is nothing ready to eat. So think ahead of the coming week. When will you have time to cook? Do you have the right materials already?    2    

Make your time worth it. When you do find time to cook a meal, make the most of it and save yourself time later on. Are you making one loaf of bread?    3    It takes around the same amount of time to make more of something. So save yourself the effort for a future meal.

    4    This may surprise you, but one of the best ways to make cooking worth your time is experimentation. It gives you the chance to hit upon new ideas and recipes that can work well. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.

Hopefully that gives you a good start.    5    And don’t let a busy schedule disappoint you and stop you from making some great changes in your life!

Yours,

10 . Chicken is America’s most popular meat. Many people assume chicken follows a simple rule-of-thumb: Pink chicken turned white means “done.” It’s similar to how we cook other meats. But is this true? To study how cooks at home follow safety recommendations, researchers filmed 75 households in five European countries. From a random but nonrepresentative sample, they also conducted an online survey of nearly 4,000 households in the same countries that say they cook chicken.

Worried that chicken would dry out, most home cooks determined doneness by color and texture (口感) inside the meat, they found. Few bothered with thermometers (温度计), claiming they took too much time, were too complicated to use, didn’t fit in the chicken or weren’t necessary (although easy-to-use thermometers are inexpensive and widely available).

In additional lab experiments, the scientists injected raw chicken breast with bacteria (细菌), which cause millions of sicknesses, thousands of hospitalizations and hundreds of deaths each year in the United States. They cooked the breasts until they reached core temperatures ranging from 122 to 158 Fahrenheit, and they discovered something surprising. At 158 degrees, but not lower, bacteria inside the chickens’ cores was reduced to safe levels, and when cut open its flesh appeared dull and fibrous, not shiny like raw chicken. But meat began changing from pink to white far below this, and most color change occurred below 131 degrees Fahrenheit. Sometimes, the chicken’s core would be safely cooked, but unsafe levels of bacteria still existed on surfaces that hadn’t touched the grill plate.

So what are you supposed to do?

Dr. Bruno Goussault, a scientist and chef, recommends buying and cooking breasts and legs separately. Bring the breast’s core to 165 degrees Fahrenheit, he said, and the leg to between 168.8 and 172.4 Fahrenheit. If you really want to safely measure temperature for a whole chicken, insert a pop-up thermometer into the thickest part of the leg before roasting it, Dr. Goussault suggests. By the time it pops, the breasts will have long cooked. They will likely be dry and far from his standards of culinary (烹饪的) perfection. But you’ll be sure to, as Dr. Goussault says in French, “dormir sur ses deux oreilles,” or, figuratively, “sleep peacefully.”
