Personal Hygiene


Personal Hygiene: Healthy Habits Include Good Grooming
If you want to minimize your risk of infection and also enhance your overall health, follow these basic personal hygiene habits:
·         Bathe regularly. Wash your body and your hair often. “I’m not saying that you need to shower or bathe every day,” remarks Dr. Novey. “But you should clean your body and shampoo your hair at regular intervals that work for you.” Your body is constantly shedding skin. Novey explains, “That skin needs to come off. Otherwise, it will cake up and can cause illnesses.”
·         Trim your nails. Keeping your finger and toenails trimmed and in good shape will prevent problems such as hang nails and infected nail beds. Feet that are clean and dry are less likely to contract athlete’s foot, Novey says.
·         Brush and floss. Ideally, you should brush your teeth after every meal. At the very least, brush your teeth twice a day and floss daily. Brushing minimizes the accumulation of bacteria in your mouth, which can cause tooth decay and gum disease, Novey says. Flossing, too, helps maintain strong, healthy gums. “The bacteria that builds up and causes gum disease can go straight to the heart and cause very serious valve problems,” Novey explains. Unhealthy gums also can cause your teeth to loosen, which makes it difficult to chew and to eat properly, he adds. To maintain a healthy smile, visit the dentist at six-month intervals for checkups and cleanings.
·         Wash your hands. Washing your hands before preparing or eating food, after going to the bathroom, after coughing or sneezing, and after handling garbage, goes a long way toward preventing the spread of bacteria and viruses. Keep a hygiene product, like an alcohol-based sanitizing gel, handy for when soap and water isn’t available.
·         Sleep tight. Get plenty of rest — 8 to 10 hours a night — so that you are refreshed and are ready to take on the day every morning. Lack of sleep can leave you feeling run down and can compromise your body's natural defenses, your immune system, Novey says.
  Personal Hygiene: Poor Hygiene Hints at Other Issues
If someone you know hasn’t bathed or appears unkempt, it could be a sign that he or she is depressed. “When people are sad or depressed, they neglect themselves,” Novey says. Talking about the importance of proper personal hygiene for preventing illnesses and providing personal hygiene items may help some people. Be candid but sensitive and understanding in your discussions, Novey says. Despite your best efforts, your friend or loved one may need professional help. You should encourage them to see a counselor or doctor if their personal hygiene doesn’t improve.
Personal Hygiene: Good Habits Help Keep You Healthy
For most people, good hygiene is so much a part of their daily routines that they think little about it. They bathe, they brush their teeth, visit the dentist and doctor for regular checkups, and wash their hands when preparing or eating food and handling unsanitary items. To keep those you care about healthy and safe, help them learn, and be sure that they are practicing, good personal hygiene.




Some Myths about Nutrition & Physical Activity/chapter-5

Some Myths about Nutrition & Physical Activity
Are you overwhelmed by daily decisions about what to eat, how much to eat, when to eat, and how much physical activity you need to be healthy? If so, don’t be discouraged because you’re not alone. With so many choices and decisions, it can be hard to know what to do and which information you can trust.
This information may help you make changes in your daily eating and physical activity habits so that you improve your well-being and reach or maintain a healthy weight.
Food Myths
Myth: To lose weight, you have to give up all your favorite foods.
Fact: You don’t have to give up all your favorite foods when you’re trying to lose weight. Small amounts of your favorite high-calorie foods may be part of your weight-loss plan. Just remember to keep track of the total calories you take in. To lose weight, you must burn more calories than you take in through food and beverages.
TIP: Limiting foods that are high in calories may help you lose weight. It is  estimated daily calorie needs based on a person’s age, sex, and physical activity level.
Myth: Grain products such as bread, pasta, and rice are fattening. You should avoid them when trying to lose weight.
Fact: Grains themselves aren’t necessarily fattening—or unhealthy–although substituting whole grains for refined-grain products is healthier and may help you feel fuller. The Dietary Guidelines for Americans 2015-2020 recommend consuming grains as part of a healthy eating plan . At least half of the grains you eat should be whole grains. Examples of whole grains include brown rice and whole-wheat bread, cereal, and pasta. Whole grains provide iron, fiber, and other important nutrients.
TIP: Try to replace refined or white bread with whole-wheat bread and refined pasta with whole-wheat pasta. Or add whole grains to mixed dishes, such as brown instead of white rice to stir fry. Check out ChooseMyPlate for more tips to help you add whole grains  to your eating plan.
Myth: Choosing foods that are gluten-free will help you eat healthier.
Fact: Gluten-free foods are not healthier if you don’t have celiac disease or are not sensitive to gluten. Gluten is a protein found in wheat, barley, and rye grains. A health care professional is likely to prescribe a gluten-free eating plan to treat people who have celiac disease or are sensitive to gluten. If you don’t have these health problems but avoid gluten anyway, you may not get the vitamins, fiber, and minerals you need. A gluten-free diet is not a weight-loss diet and is not intended to help you lose weight.
TIP: Before you decide to avoid a whole food group, talk with your health care professional if you believe you have problems after you consume foods or drinks with wheat, barley, or rye.
Myth: You should avoid all fats if you’re trying to be healthy or lose weight.
Fact: You do not have to avoid all fats if you’re trying to improve your health or lose weight. Fatprovides essential nutrients and should be an important part of a healthy eating plan. But because fats have more calories per gram than protein or carbohydrates, or “carbs,” you need to limit fats to avoid extra calories. If you are trying to lose weight, consider eating small amounts of food with healthy fats, such as avocados, olives, or nuts. You also could replace whole-fat cheese or milk with lower-fat versions. Read about food portions and how much food is enough for you.
TIP: The Dietary Guidelines for Americans 2015-2020 recommend consuming less than 10 percent of your daily calories from saturated fats. Try cutting back on solid-fat foods. Use olive oil instead of butter in cooking.
Myth: Dairy products are fattening and unhealthy.
Fact: Dairy products are an important food group because they have protein your body needs to build muscles and help organs work well, and calcium to strengthen bones. Most dairy products, such as milk and some yogurts, have added vitamin D to help your body use calcium, since many Americans don’t get enough of these nutrients. Dairy products made from fat-free or low-fat milk have fewer calories than dairy products made from whole milk. Learn more about the dairy group .
TIP: Adults should have 3 servings a day of fat-free or low-fat dairy products, including milk or milk products such as yogurt and cheese, or fortified soy beverages, as part of a healthy eating plan. If you can’t digest lactose, the sugar found in dairy products, choose fortified soy products, lactose-free or low-lactose dairy products, or other foods and beverages with calcium and vitamin D:
·         Calcium—soy-based beverages or tofu made with calcium sulfate, canned salmon, or dark leafy greens such as collards or kale
·         vitamin D—cereals or soy-based beverages
Myth: “Going vegetarian” will help you lose weight and be healthier.
Fact: Some research shows that a healthy vegetarian eating plan, or one made up of foods that come mostly from plants , may be linked to lower levels of obesity, lower blood pressure, and a reduced risk of heart disease. But going vegetarian will only lead to weight loss if you reduce the total number of calories you take in. Some vegetarians may make food choices that could lead to weight gain, such as eating a lot of food high in sugar, fats, and calories.
Eating small amounts of lean meats can also be part of a healthy plan to lose or maintain weight. The U.S. Dietary Guidelines 2015-2020 have more information about including meat as part of a healthy eating plan .
TIP: If you choose to follow a vegetarian eating plan, be sure you get enough of the nutrients your body needs to be healthy. Read Healthy Eating Tips for Vegetarians  for more information.
Physical Activity Myths
Myth: Physical activity only counts if you do it for long periods of time.
Fact: You don’t need to be active for long periods to get the amount of regular physical activity recommended in the Physical Activity Guidelines for Americans, 2nd edition , (PDF, 14.2MB)  which is at least 150 minutes, or 2 hours and 30 minutes, of moderate-intensity physical activity each week. An example of moderate-intensity activity is brisk walking. You can spread these sessions out over the week and even do short, 10-minute spurts of activity 3 times a day on 5 or more days a week.
TIP: Find ways to build short bursts of physical activity into your day. While at work, take a 10-minute walking break or have a “walking,” rather than a “sitting” meeting, if work and schedule permit. Use stairs instead of an elevator or escalator. Get off the bus one stop early. Meet a friend for a walk, instead of a meal.
Myth: Lifting weights is not a good way to improve your health or lose weight because it will make you “bulk up.”
Do muscle-strengthening activities at least twice a week.
Fact: Lifting weights or doing other activities 2 or 3 days a week that may help you build strong muscles, such as push-ups and some types of yoga, will not bulk you up. Only intense strength training, along with certain genes, can build large muscles. Like other kinds of physical activity, muscle-strengthening activities will help improve your health and also may help you control your weight by increasing the amount of energy-burning muscle.
TIP: Using large rubber bands, or resistance bands, or doing sit-ups or household or yard chores that make you lift or dig, may help you build strong muscles.


causes and symptons of food-borne illness/CHAPTER-5


What are foodborne illnesses?
Foodborne illnesses are infections or irritations of the gastrointestinal (GI) tract caused by food or beverages that contain harmful bacteria, parasites, viruses, or chemicals. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Common symptoms of foodborne illnesses include vomiting, diarrhea, abdominal pain, fever, and chills.
Most foodborne illnesses are acute, meaning they happen suddenly and last a short time, and most people recover on their own without treatment. Rarely, foodborne illnesses may lead to more serious complications.
What causes foodborne illnesses?
The majority of foodborne illnesses are caused by harmful bacteria and viruses.2 Some parasites and chemicals also cause foodborne illnesses.
Bacteria
Bacteria are tiny organisms that can cause infections of the GI tract. Not all bacteria are harmful to humans.
Some harmful bacteria may already be present in foods when they are purchased. Raw foods including meat, poultry, fish and shellfish, eggs, unpasteurized milk and dairy products, and fresh produce often contain bacteria that cause foodborne illnesses. Bacteria can contaminate food—making it harmful to eat—at any time during growth, harvesting or slaughter, processing, storage, and shipping.
Foods may also be contaminated with bacteria during food preparation in a restaurant or home kitchen. If food preparers do not thoroughly wash their hands, kitchen utensils, cutting boards, and other kitchen surfaces that come into contact with raw foods, cross-contamination—the spread of bacteria from contaminated food to uncontaminated food—may occur.
If hot food is not kept hot enough or cold food is not kept cold enough, bacteria may multiply. Bacteria multiply quickly when the temperature of food is between 40 and 140 degrees. Cold food should be kept below 40 degrees and hot food should be kept above 140 degrees. Bacteria multiply more slowly when food is refrigerated, and freezing food can further slow or even stop the spread of bacteria. However, bacteria in refrigerated or frozen foods become active again when food is brought to room temperature. Thoroughly cooking food kills bacteria.
Many types of bacteria cause foodborne illnesses. Examples include
·         Salmonella, a bacterium found in many foods, including raw and undercooked meat, poultry, dairy products, and seafood. Salmonella may also be present on egg shells and inside eggs.
·         Campylobacter jejuni (C. jejuni), found in raw or undercooked chicken and unpasteurized milk.
·         Shigella, a bacterium spread from person to person. These bacteria are present in the stools of people who are infected. If people who are infected do not wash their hands thoroughly after using the bathroom, they can contaminate food that they handle or prepare. Water contaminated with infected stools can also contaminate produce in the field.
·         Escherichia coli (E. coli), which includes several different strains, only a few of which cause illness in humans. E. coli O157:H7 is the strain that causes the most severe illness. Common sources of E. coli include raw or undercooked hamburger, unpasteurized fruit juices and milk, and fresh produce.
·         Listeria monocytogenes (L. monocytogenes), which has been found in raw and undercooked meats, unpasteurized milk, soft cheeses, and ready-to-eat deli meats and hot dogs.
·         Vibrio, a bacterium that may contaminate fish or shellfish.
·         Clostridium botulinum (C. botulinum), a bacterium that may contaminate improperly canned foods and smoked and salted fish.

Viruses

Viruses are tiny capsules, much smaller than bacteria, that contain genetic material. Viruses cause infections that can lead to sickness. People can pass viruses to each other. Viruses are present in the stool or vomit of people who are infected. People who are infected with a virus may contaminate food and drinks, especially if they do not wash their hands thoroughly after using the bathroom.
Common sources of foodborne viruses include
·         food prepared by a person infected with a virus
·         shellfish from contaminated water
·         produce irrigated with contaminated water
Common foodborne viruses include
·         norovirus, which causes inflammation of the stomach and intestines
·         hepatitis A, which causes inflammation of the liver

Parasites

Parasites are tiny organisms that live inside another organism. In developed countries such as the United States, parasitic infections are relatively rare.
Cryptosporidium parvum and Giardia intestinalis are parasites that are spread through water contaminated with the stools of people or animals who are infected. Foods that come into contact with contaminated water during growth or preparation can become contaminated with these parasites. Food preparers who are infected with these parasites can also contaminate foods if they do not thoroughly wash their hands after using the bathroom and before handling food.
Trichinella spiralis is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game.

Chemicals

Harmful chemicals that cause illness may contaminate foods such as
·         fish or shellfish, which may feed on algae that produce toxins, leading to high concentrations of toxins in their bodies. Some types of fish, including tuna and mahi mahi, may be contaminated with bacteria that produce toxins if the fish are not properly refrigerated before they are cooked or served.
·         certain types of wild mushrooms.
·         unwashed fruits and vegetables that contain high concentrations of pesticides.

Who gets foodborne illnesses?

Anyone can get a foodborne illness. However, some people are more likely to develop foodborne illnesses than others, including
·         infants and children
·         pregnant women and their fetuses
·         older adults
·         people with weak immune systems
These groups also have a greater risk of developing severe symptoms or complications of foodborne illnesses.

What are the symptoms of foodborne illnesses?

Symptoms of foodborne illnesses depend on the cause. Common symptoms of many foodborne illnesses include
·         vomiting
·         diarrhea or bloody diarrhea
·         abdominal pain
·         fever
·         chills
Symptoms can range from mild to serious and can last from a few hours to several days.
C. botulinum and some chemicals affect the nervous system, causing symptoms such as
·         headache
·         tingling or numbness of the skin
·         blurred vision
·         weakness
·         dizziness
·         paralysis

What are the complications of foodborne illnesses?

Foodborne illnesses may lead to dehydration, hemolytic uremic syndrome (HUS), and other complications. Acute foodborne illnesses may also lead to chronic—or long lasting—health problems.

Dehydration

When someone does not drink enough fluids to replace those that are lost through vomiting and diarrhea, dehydration can result. When dehydrated, the body lacks enough fluid and electrolytes—minerals in salts, including sodium, potassium, and chloride—to function properly. Infants, children, older adults, and people with weak immune systems have the greatest risk of becoming dehydrated.
Signs of dehydration are
·         excessive thirst
·         infrequent urination
·         dark-colored urine
·         lethargy, dizziness, or faintness
Signs of dehydration in infants and young children are
·         dry mouth and tongue
·         lack of tears when crying
·         no wet diapers for 3 hours or more
·         high fever
·         unusually cranky or drowsy behavior
·         sunken eyes, cheeks, or soft spot in the skull
Also, when people are dehydrated, their skin does not flatten back to normal right away after being gently pinched and released.
Severe dehydration may require intravenous fluids and hospitalization. Untreated severe dehydration can cause serious health problems such as organ damage, shock, or coma—a sleeplike state in which a person is not conscious.

HUS

Hemolytic uremic syndrome is a rare disease that mostly affects children younger than 10 years of age. HUS develops when E. coli bacteria lodged in the digestive tract make toxins that enter the bloodstream. The toxins start to destroy red blood cells, which help the blood to clot, and the lining of the blood vessels.
In the United States, E. coli O157:H7 infection is the most common cause of HUS, but infection with other strains of E. coli, other bacteria, and viruses may also cause HUS. A recent study found that about 6 percent of people with E. coli O157:H7 infections developed HUS. Children younger than age 5 have the highest risk, but females and people age 60 and older also have increased risk.3
Symptoms of E. coli O157:H7 infection include diarrhea, which may be bloody, and abdominal pain, often accompanied by nausea, vomiting, and fever. Up to a week after E. coli symptoms appear, symptoms of HUS may develop, including irritability, paleness, and decreased urination. HUS may lead to acute renal failure, which is a sudden and temporary loss of kidney function. HUS may also affect other organs and the central nervous system. Most people who develop HUS recover with treatment. Research shows that in the United States between 2000 and 2006, fewer than 5 percent of people who developed HUS died of the disorder. Older adults had the highest mortality rate—about one-third of people age 60 and older who developed HUS died.3
Studies have shown that some children who recover from HUS develop chronic complications, including kidney problems, high blood pressure, and diabetes.

Other Complications

Some foodborne illnesses lead to other serious complications. For example, C. botulinum and certain chemicals in fish and seafood can paralyze the muscles that control breathing. L. monocytogenes can cause spontaneous abortion or stillbirth in pregnant women.
Research suggests that acute foodborne illnesses may lead to chronic disorders, including
·         reactive arthritis, a type of joint inflammation that usually affects the knees, ankles, or feet. Some people develop this disorder following foodborne illnesses caused by certain bacteria, including C. jejuni and Salmonella. Reactive arthritis usually lasts fewer than 6 months, but this condition may recur or become chronic arthritis.4
·         irritable bowel syndrome (IBS), a disorder of unknown cause that is associated with abdominal pain, bloating, and diarrhea or constipation or both. Foodborne illnesses caused by bacteria increase the risk of developing IBS.5
·         Guillain-Barré syndrome, a disorder characterized by muscle weakness or paralysis that begins in the lower body and progresses to the upper body. This syndrome may occur after foodborne illnesses caused by bacteria, most commonly C. jejuni. Most people recover in 6 to 12 months.6
A recent study found that adults who had recovered from E. coli O157:H7 infections had increased risks of high blood pressure, kidney problems, and cardiovascular disease.7

When should people with foodborne illnesses see a health care provider?

People with any of the following symptoms should see a health care provider immediately:
·         signs of dehydration
·         prolonged vomiting that prevents keeping liquids down
·         diarrhea for more than 2 days in adults or for more than 24 hours in children
·         severe pain in the abdomen or rectum
·         a fever higher than 101 degrees
·         stools containing blood or pus
·         stools that are black and tarry
·         nervous system symptoms
·         signs of HUS
If a child has a foodborne illness, parents or guardians should not hesitate to call a health care provider for advice.

How are foodborne illnesses diagnosed?

To diagnose foodborne illnesses, health care providers ask about symptoms, foods and beverages recently consumed, and medical history. Health care providers will also perform a physical examination to look for signs of illness.
Diagnostic tests for foodborne illnesses may include a stool culture, in which a sample of stool is analyzed in a laboratory to check for signs of infections or diseases. A sample of vomit or a sample of the suspected food, if available, may also be tested. A health care provider may perform additional medical tests to rule out diseases and disorders that cause symptoms similar to the symptoms of foodborne illnesses.
If symptoms of foodborne illnesses are mild and last only a short time, diagnostic tests are usually not necessary.

How are foodborne illnesses treated?

The only treatment needed for most foodborne illnesses is replacing lost fluids and electrolytes to prevent dehydration.
Over-the-counter medications such as loperamide (Imodium) and bismuth subsalicylate (Pepto-Bismol and Kaopectate) may help stop diarrhea in adults. However, people with bloody diarrhea—a sign of bacterial or parasitic infection—should not use these medications. If diarrhea is caused by bacteria or parasites, over-the-counter medications may prolong the problem. Medications to treat diarrhea in adults can be dangerous for infants and children and should only be given with a health care provider’s guidance.
If the specific cause of the foodborne illness is diagnosed, a health care provider may prescribe medications, such as antibiotics, to treat the illness.
Hospitalization may be required to treat lifethreatening symptoms and complications, such as paralysis, severe dehydration, and HUS.

Eating, Diet, and Nutrition

The following steps may help relieve the symptoms of foodborne illnesses and prevent dehydration in adults:
·         drinking plenty of liquids such as fruit juices, sports drinks, caffeine-free soft drinks, and broths to replace fluids and electrolytes
·         sipping small amounts of clear liquids or sucking on ice chips if vomiting is still a problem
·         gradually reintroducing food, starting with bland, easy-to-digest foods such as rice, potatoes, toast or bread, cereal, lean meat, applesauce, and bananas
·         avoiding fatty foods, sugary foods, dairy products, caffeine, and alcohol until recovery is complete
Infants and children present special concerns. Infants and children are likely to become dehydrated more quickly from diarrhea and vomiting because of their smaller body size. The following steps may help relieve symptoms and prevent dehydration in infants and children:
·         giving oral rehydration solutions such as Pedialyte, Naturalyte, Infalyte, and CeraLyte to prevent dehydration
·         giving food as soon as the child is hungry
·         giving infants breast milk or fullstrength formula, as usual, along with oral rehydration solutions
Older adults and adults with weak immune systems should also drink oral rehydration solutions to prevent dehydration.

How are foodborne illnesses prevented?

Foodborne illnesses can be prevented by properly storing, cooking, cleaning, and handling foods.
·         Raw and cooked perishable foods—foods that can spoil—should be refrigerated or frozen promptly. If perishable foods stand at room temperature for more than 2 hours, they may not be safe to eat. Refrigerators should be set at 40 degrees or lower and freezers should be set at 0 degrees.
·         Foods should be cooked long enough and at a high enough temperature to kill the harmful bacteria that cause illnesses. A meat thermometer should be used to ensure foods are cooked to the appropriate internal temperature:
o 145 degrees for roasts, steaks, and chops of beef, veal, pork, and lamb, followed by 3 minutes of rest time after the meat is removed from the heat source
o 160 degrees for ground beef, veal, pork, and lamb
o 165 degrees for poultry
·         Cold foods should be kept cold and hot foods should be kept hot.
·         Fruits and vegetables should be washed under running water just before eating, cutting, or cooking. A produce brush can be used under running water to clean fruits and vegetables with firm skin.
·         Raw meat, poultry, seafood, and their juices should be kept away from other foods.
·         People should wash their hands for at least 20 seconds with warm, soapy water before and after handling raw meat, poultry, fish, shellfish, produce, or eggs. People should also wash their hands after using the bathroom, changing diapers, or touching animals.
·         Utensils and surfaces should be washed with hot, soapy water before and after they are used to prepare food. Diluted bleach—1 teaspoon of bleach to 1 quart of hot water—can also be used to sanitize utensils and surfaces.

Traveler’s Diarrhea

People who visit certain foreign countries are at risk for traveler’s diarrhea, which is caused by eating food or drinking water contaminated with bacteria, viruses, or parasites. Traveler’s diarrhea can be a problem for people traveling to developing countries in Africa, Asia, Latin America, and the Caribbean. Visitors to Canada, most European countries, Japan, Australia, and New Zealand do not face much risk for traveler’s diarrhea.
To prevent traveler’s diarrhea, people traveling from the United States to developing countries should avoid
·         drinking tap water, using tap water to brush their teeth, or using ice made from tap water
·         drinking unpasteurized milk or milk products
·         eating raw fruits and vegetables, including lettuce and fruit salads, unless they peel the fruits or vegetables themselves
·         eating raw or rare meat and fish
·         eating meat or shellfish that is not hot when served
·         eating food from street vendors
Travelers can drink bottled water, bottled soft drinks, and hot drinks such as coffee or tea.
People concerned about traveler’s diarrhea should talk with a health care provider before traveling. The health care provider may recommend that travelers bring medication with them in case they develop diarrhea during their trip. Health care providers may advise some people—especially people with weakened immune systems—to take antibiotics before and during a trip to help prevent traveler’s diarrhea. Early treatment with antibiotics can shorten a bout of traveler’s diarrhea.
