1. A quick look at junk food facts tells us junk food and diets do not go hand in hand. Junk foods are also called 'empty calorie' foods and have no nutritional value. Nevertheless, they are enjoyed by lots of people because of their simplicity to manufacture, consume and, of course, their taste. Chocolates, burgers, pizzas, potato wafers and fries will surely find their way into everyone's heart.

2. Thai cuisine is one of the healthiest foods you can eat. In fact, several Thai dishes, such as Tom Yum Soup, are currently under scientific study for their incredible health benefits. Of course, it's already known that many of the fresh herbs and spices used in Thai cooking - such as turmeric, galangal, coriander, lemongrass, and fresh chillies - have immune-boosting and disease-fighting power.

3. Vegetarian diets can be very healthy, but eating a balanced diet when you are vegetarian usually requires a little extra attention. Because vegetarians eliminate certain foods from their diets, they often need to work to add foods into their diet that will provide the nutrients found in meat products. If properly planned, vegetarian diets can provide all the nutrients you need.

4. It's actually easy to make good choices at a fast-food restaurant or the cafeteria. Most cafeterias and fast-food places offer healthy choices that are also tasty, like grilled chicken or salads. Be mindful of portion sizes and high fat add-ons, like dressings, sauces or cheese. Most restaurant portions are larger than the average serving of food at home. Ask for half portions or take half of your dish home.

5. Family meals are making a comeback. Shared family meals are more likely to be nutritious, and kids who eat regularly with their families are less likely to snack on unhealthy foods and more likely to eat fruits and vegetables. Teens who take part in regular family meals are less likely to smoke, drink alcohol, or use drugs. Beyond health and nutrition, family meals provide a valuable opportunity to reconnect.

6. Families are cooking more meals at home, cutting back on take away in the face of the economic downturn. In addition to cutting back on take away and eating out, families have begun cooking more vegetarian meals and are adding vegetables, lentils and baked beans to allow them to cut back on meat quantity. Consumers also indicate that they are likely to prepare meals that can be spread across more than one mealtime.

7. In recent years it has become common practice for celebrities and stars to publicize food products. Businesses take advantage of consumers' mentality of 'following the stars' and invite celebrities and stars to perform 'false advertising' so as to mislead or even deceive consumers. The law stipulates that those who publicize 'faulty food products' will share responsibility with food producers and sellers.
