Q: The foods which may irritate ulcers vary from person to person. Some people can eat whatever they like without any increased irritation, but this is not true for everyone. You will have to learn over time which foods cause you problems and cut them out or limit them in your diet. This also helps to prevent ulcers in the future. A good place to start is with foods which increase your stomach acid production. Patients with peptic ulcers should avoid diets rich in red meat, fried or fatty foods, and refined foods, such as flour or sugar. Be cautious of dairy foods with whole milk or cream. Spearmint, peppermint, and other minty foods seem to increase the production of stomach acid. Diets heavy in these foods can lead to further ulcer irritation and an increase in stomach acid. As well as foods that can provoke increased production of stomach acid, some other foods can irritate your ulcer more directly. In practice, this will vary from person to person, but there are some general recommendations for those with an ulcer. The first of these is to try to avoid eating spicy food. The sting you feel from spicy food if you have a cut on your finger or mouth can be replicated in your stomach or intestine if you have an ulcer. The second recommendation is to avoid citrus and acidic foods and drinks. Highly acidic orange or lemon juice could irritate the ulcer and cause you pain. You should also be wary of tomato products, onions and garlic and heavily seasoned food in general. Diets rich in whole grains and fiber rich foods, with limited dairy, help control the production of stomach acid. Ensure you get plenty of fibrous vegetables as part of your healthy balanced diet. If you are not consuming enough vitamin-rich foods your body may find it harder to heal your ulcer. Good sources of fiber are whole-wheat bread, pasta, and brown rice. Opt for limited amounts of lean meat, and limited low fat dairy products. There is no single recommended diet for those with an ulcer, so you should think about what food causes you irritation and discuss this with your doctor. Eating foods rich in antioxidants (blueberries, cherries, tomatoes, squash, and bell peppers), flavonoids (apples, celery, cranberries, onions, garlic, and tea), B vitamins and calcium (almonds, beans, whole grains, spinach, kale, and sea vegetables) may also help to reduce your symptoms. Continue to drink 6-8 glasses of water each day as part of your healthy diet. A peptic ulcer sufferer is not advised to eat sporadic meals that vary in size. Doing so may cause disruption in the normal production of stomach acid, and end up irritating an ulcer. Keeping meals small and regular can help level out stomach acid. Your stomach may deal better with small regular meals than large irregular ones. Avoid eating anything at least two hours before you go to bed.
A: Avoid food that increases the production of stomach acid. Steer clear of food that may irritant your ulcer. Eat plenty of fiber. Eat meals according to a regular schedule.

Q: Although there's nothing you can do about hormonal changes during pregnancy, you do have control over your diet. Avoid eating spicy, fatty and fried foods, which can cause acid reflux (heartburn). Cut back on processed snacks like chips and pretzels. Instead, eat whole-grain foods, fresh fruits and veggies, lean meats and low-fat dairy. Chocolate, mustard, tomatoes (and sauces), onions, processed meats and citrus fruits can trigger heartburn in sensitive people. Avoid seasoning your food with pepper, vinegar, ketchup, etc. In general, eat plain and natural during pregnancy. Another strategy for coping with heartburn during pregnancy is to eat smaller, more frequent meals spread throughout the day. Eating large meals tends to overfill your stomach and increases the risk of digestive juices creeping up your esophagus, so stick to smaller portions. While pregnant, you don't want to go hungry and prevent your baby from getting essential nutrients, so eat every two to three hours. In general, your portion shouldn't exceed the volume created when you cup both hands together. You should also take your time eating and chew thoroughly in order to partially "predigest" your food. Chew your food for at least 20 seconds before swallowing. Eating close to bedtime promotes heartburn because lying flat makes it easier for stomach acid to escape into your esophagus and irritate it. As such, don't eat anything for between two to three hours prior to lying down in order to give yourself enough time to properly digest. In general, meat takes about twice as long to digest as fruits and most veggies. If your bedtime is 10pm, then meats, fish and poultry should be eaten no later than 7pm. Salads, pastas and rice dishes can be eaten as late as 8pm or a little later. If you're hungry as you head to bed, try drinking a little water or herbal tea to take the edge off your hunger. In addition to food, many beverages can trigger overproduction of acid in your stomach. Acidic drinks to avoid while pregnant include carbonated beverages (especially colas), alcohol beverages (especially red wine), hot chocolate, coffee and sweetened citrus juices (OJ, lemonade, etc.). Caffeine is a also a trigger for heartburn, so colas and coffee tend to be a "double whammy" as far as heartburn is concerned. In addition to purified water, herbal tea, dairy milk and almond beverages are generally safe to drink if you're trying to cope with heartburn. Don't drink large volumes of liquids during meals you'll distend your stomach.
A: Avoid foods that commonly trigger heartburn. Eat smaller meals. Don't eat too close to bedtime. Avoid beverages that cause gastrointestinal distress.

Q: The concentrated hydrogen peroxide used in this experiment will burn the skin and eyes. It can also bleach fabric, so choose your clothing with that in mind. This hydrogen peroxide is stronger than any household peroxide. Be sure to handle with care and make sure the graduated cylinder is set on a stable location. Play with the food dye for fun effects. Create fun patterns and color variations. To make the final product striped, tilt the graduated cylinder and drip food coloring down the sides. Add a small layer of liquid dish soap by pouring it into the solution down the side of the cylinder. You can also use powdered dish soap but be sure to mix the solution thoroughly. Using a spatula, add the potassium iodide to create the chemical reaction. You can also dissolve the potassium iodide in water in a vial before adding to the solution. Large colored foam will rise out of the cylinder. Place a glowing wood splint near the foam and watch it reignite as the oxygen is released from the emerging foam. Flush the remaining solution down the drain using plenty of water. Make sure all glowing wood splints are out and there are no open flames. Close and store the hydrogen peroxide and potassium iodide.
A:
Put on gloves and goggles. Pour 4tsp (20ml) of 30% hydrogen peroxide into a graduated cylinder. Add 3 drops of food coloring. Add about 212UStbsp (37ml) of dish soap and swirl it to mix. Add the potassium iodide to the solution and quickly stand back! Test for the presence of oxygen. Clean up.
