1. Popcorn
Many are enticed by the sweet aroma of popcorn, but it's actually loaded with chemicals. Every time you open a bag of popcorn, you're increasing your risk of health problems. Popcorn is a favorite snack for children, but consuming too much can lead to lead poisoning. The lead content in popcorn can reach 10 mg per 500g, affecting the nervous and digestive systems of kids.
This snack is not recommended for children under 5 years old, as they may choke on it, which can lead to suffocation.

2. Sausages
Sausages and other red meat products are highly popular. However, experts warn that eating even one sausage a day can be harmful to children. Processed meats like sausages can increase the risk of diabetes, heart disease, and various cancers. In Vietnam, many parents still consider sausages a convenient snack, often replacing meals or offering them as a quick bite outside regular meals.
Experts say sausages are made from fatty meats, high in energy but low in nutrition, offering no health benefits for adults and especially harmful to children's development. Sausages also contain chemicals, additives, and preservatives that force the liver to work harder to detoxify the body.
Additionally, many street vendors sell sausages from unclear sources, often made from spoiled meat in unhygienic, unsafe conditions.

3. Jelly
The main ingredient in jelly is carrageenan, a type of biopolymer extracted from seaweed, which has certain benefits for gut function. However, consuming too much can hinder the absorption of minerals. Jelly also contains water, sugar, emulsifiers like sodium alginate, agar powder, and flavorings. Sodium alginate and agar are types of fiber, but excessive consumption can affect the absorption of fats and proteins. Jelly is slippery and often made in cylindrical shapes, making it easy to push out quickly, which can cause children to accidentally choke on large pieces. Its soft texture can change shape in the airway, making it easier to block the airways, potentially leading to suffocation. When using utensils to serve jelly, it can break into pieces, which can cause further choking hazards.
To prevent choking, it's best to avoid giving jelly to children under 5, as their swallowing reflex is not fully developed. For older children, break the jelly into small pieces and feed them slowly with a spoon. If a child chokes on jelly, do not attempt to remove it with your hands as this may push the object deeper. In cases of suffocation, immediately turn the child upside down and firmly pat their back to clear the airway. Rush to the nearest hospital for emergency care if needed.

4. Chewing Gum
Did you know that chewing gum contains sorbitol, a sweetener that can be harmful to children's developing digestive systems? Small children are at risk of swallowing gum, as it’s made of gum base that doesn't digest and can remain in the stomach forever, potentially causing a bowel obstruction, which is life-threatening. If a child accidentally swallows chewing gum, ensure they drink plenty of water and eat soft food like porridge with finely chopped vegetables to avoid constipation and intestinal blockage.

5. Ice Cream
Made from milk, ice cream does have some nutritional value. However, certain types contain nuts, artificial colors, or flavoring agents that can be unsafe for children. While ice cream from reputable stores can be considered safe, ice cream from street vendors may be contaminated and cause diarrhea or even food poisoning.
Children should only consume ice cream after the age of 4. Babies under 1 year old should never eat ice cream, as their immune system is still weak, and even a cold bite can cause a sore throat. Additionally, ice cream can stick to the tongue and melt in the mouth, making it uncomfortable and increasing the likelihood of spitting up.
Cold ice cream is also harmful to children's teeth. The sucking habit that many children develop while eating ice cream can damage their teeth, erode enamel, and even cause small fractures in the teeth.

6. Lollipops
Lollipops, with their sweet taste and colorful design, are especially appealing to children. However, when you look at the ingredients, you'll see they are made from sugar, artificial colors, flavoring agents, and lack any vitamins, minerals, calcium, or iron, offering almost no nutritional value.
Like other sugary candies, lollipops are bad for teeth and can easily cause cavities, especially if the child doesn’t rinse their mouth or brush their teeth properly. Eating a lollipop before meals can also ruin their appetite, making it difficult for them to finish their main meal.
Additionally, many children enjoy running around while sucking on a lollipop, which is dangerous as the plastic stick can slip and injure the child. Parents should always supervise their child when they are eating a lollipop.

7. Honey
Many mothers in the past believed honey was completely safe for babies, often using it to treat tongue thrush or mild coughs. However, honey can be dangerous for infants under 12 months if it contains Clostridium botulinum spores, which cause a severe form of food poisoning. The chances of honey containing these spores are about 5%, which is relatively small, but the consequences can be severe, ranging from neurological damage to even death.
Adults are not affected by the spores, as their mature digestive systems can neutralize them. However, babies under 12 months lack the beneficial bacteria needed to destroy the spores, allowing them to grow and produce toxins in the baby's system.

8. Chips
Chips are a popular snack for many children, but few are aware that they contain acrylamide, a substance linked to cancer. This chemical forms in foods with high carbohydrate content when they are heated above 120°C.
Experts from the Nutrition Institute warn that chips cooked at high temperatures can also generate harmful trans fats. If these fats make up 5-10% or more of a person’s daily fat intake, it can lead to cardiovascular problems and high blood pressure.
Chips are also loaded with salt and sugar. Excess salt can impair kidney function, while too much sugar increases the risk of type 2 diabetes. When children eat too many chips and drink too much liquid, it can lead to stomach bloating and loss of appetite. Consequently, consuming excessive chips can lead to malnutrition and obesity, both of which are detrimental to a child's health.

9. French Fries
French fries are a beloved snack for many. However, eating them in excess can lead to significant health issues.
French fries contain a high level of acrylamide, a chemical that forms in foods when they are heated above 120°C.
The amount of acrylamide in French fries can be up to 1.5 times higher than that found in chips. Whether homemade or from a restaurant, this harmful substance is present in both. It is best to limit the consumption of this food, especially for children.
Additionally, potatoes are naturally high in calories, and the frying process only adds more. This increases the risk of obesity and other serious health problems, particularly in individuals with low physical activity.

10. Pastries
Most pastries are made from wheat flour. When baked at high temperatures, they release cancer-causing substances, similar to those found in chips and French fries. Furthermore, pastries are often loaded with refined sugar, which can spike insulin levels and promote the growth of cancer cells.
However, pastries that are baked at lower temperatures and contain less sugar do not pose this risk. It is best for parents to limit the frequency of sugary pastries, as this can help prevent obesity and reduce the risk of cancer.
