跟據國際食品資訊議會 (International Food Information Council)定義,除了基本營養素外,凡是對食用者有健康益處的,都可稱之為功能性食品。要食物產生健康效益,我們必需在日常多完化飲食中攝取到這些功能性食品。功能性食品包括完整食品 (whole foods) 例如蔬果、魚類及橄欖油等。另外亦包括加功食品(modified foods) 例如添加了額外營養素的早餐穀物和植物牛油。而在
1. Have your family members wash their hands regularly with soap and water or use alcohol-based hand gels. When everyone keeps their hands clean, viruses lose their favorite way to travel.
2. Get your children vaccinated against the flu (if they're 6 months or older). One or two shots or doses of nasal spray can help protect the entire family, because a vaccinated child will be less likely to bring home the flu bug making the rounds at school, daycare, or playgroups.
3. The eyes and nose are the two favorite entryways for cold and flu viruses, so encourage your children not to touch these places on their face during the height of the sniffling season.
4. If possible, your family should avoid close contact with people who have a cold or the flu. If your child's best friend is sniffling and sneezing, it isn't a good time for a sleepover.
5. It seems obvious, but kids often need a reminder to cover their mouth when they sneeze or cough to avoid spreading germs. Ideally, they should use a tissue and immediately throw it away. If they cover up with their hands, they'll need to wash up promptly. Or, ask them to sneeze or cough into the crook of their arm.
6. Wash counters and other surfaces with a virus-killing disinfectant or a diluted bleach solution, especially if someone in the house is already sick. And don't share cups and utensils without washing them with hot water and soap first. Cold viruses can live on a surface for as long as three hours.
7. Encourage everyone in the house to eat a balanced diet, exercise regularly, and get plenty of sleep. You can't have a healthy immune system without a healthy body.
