“Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity,” researchers recently reported in the journal Hypertension.

“Sugar-sweetened soft drinks are a significant source of calorie intake in children,” said Feng J. He, a researcher at St George’s University of London, England. “It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people.” They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption.

Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. “We found that children eating a lower-salt diet drank less fluid,” said He. “From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day.”

The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. “If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week,” Dr He said.

In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. “Both high blood pressure and obesity increase the risk of having strokes and heart attacks,” Dr He said.

Dr He recommends that parents check labels and choose low-salt food products. “Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors (感受器) and do not cause any technological or safety problems,” Dr He said.

A man came home from work late, tired and found his 5-year-old son waiting for him at the door.

“Daddy, may I ask you a question?” “Yeah, sure, what is it?” replied the man.  1.  “If you must know, I make $20 an hour.” “Oh,” the little boy replied, with his head down. Then he looked up and said, “Daddy, may I borrow $10?” The father was angry, “If the only reason you asked for that is to borrow some money to buy a silly toy, then you should go to bed.”  2.  

After about an hour or so, the man calmed down, and started to think. Maybe there was something he really needed to buy with that $10 and he really didn’t ask for money very often.  3. “Are you asleep, son?” He opened the door and asked. “No, Daddy,” replied the boy. “I’ve been thinking, maybe I was too hard on you just now.” said the man, “Here’s the $10 you asked for.”  4. “Oh, thank you, Daddy!” he yelled. Then, reaching under his pillow he pulled out some small change.  5. “Why do you want more money if you have already had some?” the father asked angrily.

“Because I didn’t have enough, but now I do.” The little boy replied, “Daddy, I have $20 now. Can I buy an hour of your time? Please come home earlier tomorrow, I would like to have dinner with you.”

 

A. Silently the little boy returned the money to his father with tears.

D. “Daddy, how much do you spend a day?”
