Food poisoning

Foodborne illnesses, also known as food poisoning, are caused by consuming contaminated food or drink. Foodborne illnesses can be caused by a variety of pathogens, including bacteria, viruses and parasites, as well as toxins and chemicals.

Common pathogens

1.Bacteria

• Salmonella: found in raw poultry, eggs and beef and can also be found in unwashed fruit and vegetables.
• E. coli: found in undercooked beef, especially hamburger, unpasteurized milk and juice, and contaminated water.
• Listeria monocytogenes: found in prepared foods, hot dogs and unpasteurized dairy products.

2. Viruses:

• Norovirus: highly contagious and can be spread through contaminated food, water and surfaces.
• Hepatitis A: can be transmitted through contaminated food and water, often spread by infected food handlers.

3. Parasites:

• Toxoplasma: found especially in contaminated meat that has not been thoroughly cooked, such as pork, lamb and venison.
• Giardia: often found in contaminated water and can be transmitted through food handled by infected people.

4.Toxins and chemicals:

• Botulism: Caused by toxins produced by botulism, often found in improperly canned or preserved foods.
• Scombroid poisoning: High levels of histamine are produced by eating fish that has not been properly preserved.

Symptoms:

Common symptoms of food poisoning include:

• Nausea
• vomiting
• Diarrhea
• Abdominal pain and cramps
• Fire
• Fatigue

The severity of symptoms largely depends on the pathogen, the amount of contaminated food ingested and the health status of the individual.

Recent trends and outbreaks:

1. Salmonella outbreaks: CDC has been tracking several Salmonella outbreaks occurring in each state. These outbreaks have been linked to contaminated produce, poultry, and even pet foods.
2. Hepatitis A: Cases of hepatitis A are on the rise in the US and are often associated with contaminated foods and poor hand hygiene of food handlers.
3. Norovirus: Norovirus is a major cause of foodborne outbreaks, particularly in restaurants, cruise ships and long-term care facilities. It is highly contagious and can spread rapidly through contaminated food, water and surfaces .
4. Listeria monocytogenes Outbreaks of Listeria monocytogenes have been associated with contaminated prepared foods and unpasteurized dairy products. This pathogen is particularly dangerous for pregnant women, newborns, the elderly and immunocompromised individuals .

Prevention:

1.Proper food handling and preparation:

• Wash hands, utensils and food surfaces thoroughly.
• Cook food at appropriate temperatures.
• Separate raw meat from other foods to avoid cross-contamination.
• Store food at safe temperatures.

2. Food safety practices:

• Take precautions against raw eggs and undercooked meat, fish and seafood.
• Choose pasteurized dairy products and fruit juices.
• Wash fruits and vegetables thoroughly before eating.

3. Awareness and education:

• Stay informed about recent food recalls and outbreaks.
• Train food processors on proper hygiene and food safety practices.

Conclusion:

• Foodborne illness remains a serious public health concern, with a variety of pathogens causing a range of symptoms. Staying informed about recent outbreaks and following appropriate food safety practices can reduce the risk of foodborne illness. 

sugar causes hyperactivity in children

 It is widely believed that sugar causes hyperactivity in children, but scientific evidence does not support this claim. Read more about this topic:

Myths:

The idea that sugar makes children hyperactive is a common belief among parents and caregivers. Consuming sugary foods and drinks is thought to increase children's energy levels and make them hyperactive.

Scientific research findings:

1.Research evidence: A number of studies have investigated the link between sugar intake and hyperactivity in children. The majority of well-controlled scientific studies found no significant evidence that sugar intake increases hyperactivity.

• Placebo effect: Many studies have shown that parents' expectations, rather than the actual effects of sugar, can lead them to perceive that their child is hyperactive after consuming sugar. This is known as the placebo effect.
• Behavioral observations: Observational studies often fail to control for other factors that may influence behavior, such as environment, excitement and the presence of other stimulating activities (parties, holidays, etc.)

2.Notable studies:

• One study published in the Journal of the American Medical Association concluded that sugar does not affect children's behavior or cognitive abilities.
• Another study found that parents who believed their children consumed sugar were more likely to rate their children as hyperactive, regardless of whether the child actually consumed sugar.

Factors affecting cognition:

1. Context of sugar consumption: sugar is often consumed in situations that are naturally exciting for children, such as birthday parties, holidays and celebrations, which may trigger the association between sugar and hyperactivity.
2. Attention to behavior: Parents pay more attention to their children's behavior after sugar consumption, which may lead to confirmation bias linking energetic behavior to sugar consumption.

Health considerations:

1. Dietary balance: Although sugar does not cause hyperactivity, it is important to limit sugar intake because of its association with other health problems such as obesity, tooth decay and the risk of developing type 2 diabetes.
2. Healthy alternatives: promoting a balanced diet rich in fruits, vegetables, whole grains and lean protein can support overall health and well-being.

Conclusion:

• The idea that sugar causes hyperactivity in children is not supported by scientific evidence. While parents may observe behavioral changes associated with sugar intake, these are likely to be influenced by circumstances and expectations rather than the sugar itself. However, it remains important to moderate sugar intake for overall health and to promote a balanced diet in children.

probiotics

 What are probiotics?

Probiotics are live microorganisms, often referred to as 'good' or 'friendly' bacteria, which provide health benefits when consumed in sufficient quantities. Probiotics are known to improve or restore the gut microbiota.

Benefits of probiotic yogurt

1. Digestive health: probiotics balance the gut microbiota, improve digestion and prevent problems such as constipation and diarrhea.
2. Immune support: Healthy gut flora boosts the body's immune response.
3. Nutrient absorption: probiotics increase the absorption of vitamins and minerals from food.
4. Mental health: New research shows a link between gut health and mental health and may help with symptoms such as anxiety and depression.

Common probiotic strains found in yogurt:

1. Lactobacillus acidophilus
2. Bifidobacterium bifidum
3. Lactobacillus casei
4. Streptococcus thermophilus
5. Lactobacillus bulgaricus

Probiotic-rich yogurt varieties:

• Greek yogurt: thick, creamy, high in protein, usually containing more than one strain of probiotics.
• Regular yogurt: traditional yogurt, not as thick as Greek yogurt, but rich in probiotics.
• Kefir: fermented milk drink with a pungent flavor, usually contains more probiotic strains.
• Non-dairy yogurts: made from plant-based milks such as almond, coconut and soy and can be enriched with probiotics.

How to choose a probiotic-rich yogurt

• Check the label: Look for yogurts with live or active cultures on the label.
• Minimal ingredients: choose yogurts with minimal added sugar or artificial ingredients to maximize health benefits.
• Plain yogurt: Choose plain yogurt and add fruit or sweeteners to reduce sugar intake.
• Fortified yogurts: Some yogurts are fortified with probiotics.

Include probiotic yogurts in your diet:

1. Breakfast: Enjoy yogurt with granola, nuts and fresh fruit.
2. Smoothie: Mix yogurt with fruit and vegetables for a nutritious drink.
3. Snacks: Dip yogurt in vegetables or use it as a base for healthy dips.
4. Cooking and baking: use yogurt instead of sour cream or mayonnaise to boost probiotic benefits.

Conclusion:

• Probiotic-rich yogurt is a delicious and convenient way to support gut health and overall wellbeing. When choosing yogurt, choose a yogurt that contains live, active bacterial cultures, has minimal added sugar and uses ingredients that match your dietary preferences.
