Carbonation Confusion

Monday, October 12th, 2009

tanya_zuckerbrot2Carbonated beverages like cola usually contain phosphoric acids, caffeine, large amounts of sugar, and other chemicals. These may add excess calories (if not diet), be dehydrating, and studies have shown that phosphoric acid in excess actually pulls calcium from bone making you more prone to developing osteoporosis.

But what about carbonated beverages that are caffeine-free and low sodium like club soda or Fresca? Sure, a cold, fizzy drink can be very refreshing, especially in hot weather or after a work-out.  But is there such a thing as too much?

The answer is: Yes.  Because carbonation usually causes a feeling of fullness or bloating, you may not be getting adequate fluids to rehydrate your body. The human body’s mechanism for thirst detection is very poor. Therefore, we have already been dehydrated for sometime before we feel thirsty.

Companies like Gatorade have not carbonated their products because it causes gastrointestinal distress and inhibits sufficient hydration.  Because our bodies are composed of 70 percent water, dehydration can have serious adverse effects on bodily functions and even be fatal. On a smaller scale, our skin is affected many different ways when we do not hydrate it properly. Things like age spots are partially caused by the skin being dehydrated.

When your skin is dry, you will lose the elasticity and resilience or the ability for the skin to return to its original state after pressure is applied. Due to our aging process and environmental stress the resilience or tension and elasticity of our skin gradually deteriorates and then we begin to see the appearance of age spots and wrinkles.

There is no reason to completely eliminate caffeine-free carbonated beverages from your fluid intake.  Just consume in moderation and make sure you are drinking 8 ounce glasses of non carbonated/caffeinated water per day to properly hydrate your body and skin to keep you living longer and looking better!

Coffee: Good for You!

Wednesday, September 30th, 2009

Medicine Hunter Chris Kilham (116 x 149 - on color)Guilty coffee drinkers, take heart. It’s time to clear the fog about this remarkable beverage, and to straighten out misconceptions. Coffee is just plain good for you, and here you will find ammunition for that argument.

The Coffee Tree

The plant from which coffee derives is the coffee tree, an evergreen covered with fragrant white flowers and coffee cherries at the same time. Inside the bright red skin of the coffee cherry is a pair of beans. The beans are what all of coffee is about. The simple coffee bean bears the bracing stimulant caffeine, and also yields a satisfying flavor and aroma.

Mighty Caffeine

Whatever contains caffeine will be consumed widely. Why do we love and crave caffeine? Because it makes us feel good, by stimulating valuable physical and mental functions.

A caffeine user’s guide

- Brewed coffee  (5 ounces)  80 – 175 milligrams
- Percolated coffee (5 ounces)  40 – 170 milligrams
- Instant coffee  (5 ounces)  45 – 70 milligrams
- Cappuccino (6 ounces)  60 – 120 milligrams
- Hot cocoa  (6 ounces)  2 – 8 milligrams
- Tea, brewed  (7 ounces)  60 milligrams
- Iced tea (12 ounces)  70 milligrams
- Coca Cola (12 ounces)  45.6 milligrams

Can You Consume Too Much?

Yes you can. Side effects of over-consumption include nervousness, insomnia, and tremors. Excessive caffeine consumption can produce overly rapid heartbeat, mental stress, gastric discomfort and anxiety. The human lethal dose of caffeine is equal to approximately 66 five-ounce cups of coffee. Some people do not tolerate caffeine. If caffeine makes you jittery, sweaty, sick or uncomfortable, then it isn’t your drug.

Coffee and Your Brain

Coffee’s greatest effects are exerted upon the brain and mind, for coffee is the great, bold awakener. As a caffeinated beverage, coffee stimulates the brain, facilitating cognitive function overall. Coffee stimulates the flow of blood in the brain, and invigorates the mind. It enhances alertness and motivation, facilitates thought formation and concentration, and decreases mental fatigue. Coffee rouses the mental faculties as surely as streaming sunshine and hilarious birdsong awaken the sleeping.

Within a daily dosage range of 300 milligrams of caffeine per day, coffee improves negative moods which occur in the morning upon waking, dispelling the sullen and gloomy clouds which fog the mind upon rising. Coffee, as the most flavorful and potent caffeine-bearing beverage of all, increases general happiness and feelings of pleasure, and increases positive mood overall. Coffee promotes an upbeat positive sense of self, and an overall feeling of well being.

Coffee drinking even appears to reduce the risk of Parkinson’s Disease. Coffee drinkers have between 3 to 6 times lower risk of developing Parkinson’s as compared with non-coffee drinkers.

Coffee – Take Heart

Research into the natural chemical properties of coffee shows that the daily brew is a potent protective antioxidant potion.Coffee is especially high in one group of antioxidants called flavonoids. These compounds exhibit protective power against cardiovascular disease by reducing the oxidation of LDL cholesterol, thereby helping to protect against atherosclerosis, heart attack and stroke.

Coffee and Digestion

Coffee exerts well known effects upon the digestive system andstimulatesgastric secretion. For this reason a cup of coffee after lunch or dinner may be consumed to punctuate and help digest a meal. The morning cup of coffee not only awakens the body and mind, but stimulates bowel activity as well. A strong cup increases peristalsis, the wave-like motion of the intestines. This stimulates intestinal elimination. Many people rely on a morning coffee for thorough elimination. While coffee shouldn’t substitute for a good amount of fiber in a healthy diet, its contribution to proper intestinal elimination is beneficial.

Coffee not only offers welcome laxative activity, but also plays a role in preventing some digestive disorders. Drinking two to three cups of coffee daily can reduce the risk of developing gallstones by as much as 40 percent. Coffee consumption also shows a strong protective effect against cirrhosis of the liver. Daily intake of 3 to 4 cups of coffee can reduce thr risk of cirrhosis by as much as 80 percent. Even more impressively, coffee exhibits a protective effect against colon and rectal cancers, reducing the risk by as much as 24%. 

Coffee and Cancer

If you worry that drinking coffee is going to result in some form of cancer that will take you down, you can relax. For with regard to coffee and its association with other types of cancer, again the news is good news. Several major studies have failed to show any link between coffee consumption and prostate cancer, breast cancer or bladder cancer. Nor has any link been found between coffee consumption and fibrocystic breast disease. Coffee consumption is not known to increase the risk of any type of cancer.

What about coffee and bones? Caffeine has a negative effect on calcium metabolism. And one study has found that women who consume more than 817 milligrams of caffeine per day are at three times greater risk of hip fractures than women who consume no caffeine. But other studies show that moderate consumption of coffee is not associated with bone loss, increased risk of osteoporosis, or any higher rates of bone fractures.

Women have long felt concern over their consumption of coffee and its effects on fertility and pregnancy, and any possible increased risk of miscarriage or birth defects. Again the news appears to be good. Most studies do not show any link between coffeeand decreased or delayed fertility.

Athletes who eschew coffee may think again. A few studies have shown that caffeine enhances the body’s ability to utilize body fat for exercise, and increases the body’s ability to work out before fatigue. A cup of coffee before working out can do you good, enhancing both performance and endurance.

A simple pleasure – coffee provides a pleasant lift, and offers protective benefits to health. If you are going to drink coffee, do so happily, without guilt. After all, it’s good for you.

Fat-Burning Foods

Monday, March 30th, 2009

tanya_zuckerbrot7If you are one of the many people fighting the battle of the bulge, you will be pleased to learn that there are actually foods that may help you burn fat.  You will still need to exercise and avoid over indulging. However, you may be able to speed up the fat-burning process by consuming these wonder foods.

 

1.  Low-Fat Dairy: Milk, Yogurt, Cottage Cheese
How:  They all contain calcium and studies show that not getting enough calcium may trigger the release of calcitrol, a hormone that causes us to store fat, whereas meeting your daily calcium needs helps us burn fat more efficiently. Dairy products can boost weight loss efforts, according to a study in the April issue of Obesity Research. People on a reduced-calorie diet who included three to four servings of dairy foods lost significantly more weight than those who ate a low-dairy diet containing the same number of calories. Low-fat yogurt is a rich source of weight-loss-friendly calcium, providing about 450 mg (about half the recommended daily allowance for women ages 19-50) per 8-ounce serving, as well as 12 grams of protein.

2.  Berries
How: they are high in fiber. Fiber is the magic bullet of weight loss. It keeps you full and satisfied all day on virtually no calories. A 1 cup serving of raspberries contains 8g of fiber and only 60 calories!  Strawberries, blackberries and blueberries are all other high-fiber berries.  Fiber makes us feel full sooner and stays in our stomach longer than other substances we eat, slowing down our rate of digestion and keeping us feeling full longer. Fiber also moves fat through our digestive system faster so that less of it is absorbed.

3. High-fiber cereals
How: A study from the Journal of the American Dietetic Association found that women who ate cereal were 30 percent less likely to be overweight than those who ate other breakfast foods.  High-fiber cereals have fewer calories than other breakfast options (eggs, bacon, donuts and muffins), and the fiber helps to keep you feeling full all morning so you are less likely to need a snack before lunch.  Also, fiber helps to keep insulin levels in check which prevents fat storage.

4.  Citrus Fruits: Oranges, Grapefruit, Lemon, Limes
How: Foods that contain vitamin C help metabolize fat faster and make losing weight less difficult.  You only need 60 milligrams (mg) of vitamin C a day to meet your body’s basic needs, but according to the study, raising your daily intake to 500 mg could boost your fat burning potential during exercise by 39 percent. Researchers at Scripps Clinic found that participants who ate half a grapefruit with each meal in a 12-week period lost an average of 3.6 pounds. The study indicates that the unique chemical properties in this vitamin C-packed citrus fruit reduce insulin levels, which promotes weight loss. NOTE: If you are taking medication, check with your doctor about any potentially adverse interactions with grapefruit.

5.  Green Tea
How: Green tea contains caffeine, which is a natural stimulant that can help your body burn more calories while at rest, meaning that you can burn fat without doing a thing.  Caffeine speeds up the heart rate and also frees fatty acids stored in the body, making them more readily available for energy use.  Also, green tea contains a compound called ECGC that may help to boost your metabolism by speeding up the nervous system. Green tea can also replace less healthy alternatives such as colas and excess coffee drinks which add calories to your diet.

6.  Water
How: Water helps to rid the body of toxins and chemicals that may be slowing down your overall metabolism.  By drinking at least 8 glasses of water a day, you can make sure that your digestion is running smoothly and that anything that shouldn’t be in your body is eliminated.  Many times, our hunger is really just thirst in disguise since the symptoms of dehydration mimic those of hunger (weak, cranky, tired, etc.) A new study seems to indicate that drinking water actually speeds up weight loss. Researchers in Germany found that subjects of the study increased their metabolic rates (the rate at which calories are burned) by 30 percent after drinking approximately 17 ounces of water. Water is also a natural appetite suppressant that banishes bloat as it flushes out sodium and toxins. Make sure that you are starting your day with a big glass of water and drink throughout the day not just all at one time.

7.  Soy beans: Either frozen in bags or dry-roasted
How: Soybeans contain lecitin, which helps your body keep your cells from accumulating fat. If you don’t have the time to steam them frozen, you can snack on dried or roasted ones.

8. Fish: Salmon, Tuna, Sardines
How: These fish all contain large amounts of omega-3 fatty acids which, besides being incredibly healthy, seem to affect metabolism.  Omega-3s alter levels of leptin, a hormone in the body which directly influences metabolism and determines whether you burn calories or store them as fat.  Fish contain omega-3 fatty acids (EPA and DHA) found only in fish oils. Fish oil increases the levels of fat-burning enzymes in your body and decreases the levels of fat-storage enzymes. It’s also been shown to boost your metabolism by as much as 400 calories per day. Fish like mackerel, salmon and trout are great sources of omega-3, but you can also take capsules (take at least 300mg).

9. Lean Proteins: Lean Beef, Chicken and Turkey
How: All lean meats help to speed up the metabolism and burn more fat simply because they require so much energy for complete digestion. Studies have shown that people who follow a high-protein diet burn twice as many calories after a meal as people who follow a high-carbohydrate diet.  In addition, eating protein helps to preserve muscle mass during weight loss, keeping metabolism running at full speed. Rev up your fat-burning engine with this bodybuilder favorite. Countless studies have shown that protein can help boost metabolism, lose fat and build lean muscle tissue so you burn more calories. A 3-ounce serving of boneless, skinless lean turkey breast weighs in at 120 calories and provides 26 grams of appetite-curbing protein, 1 gram of fat and 0 grams of saturated fat.

10.  Spicy Peppers: Jalapenos, Habaneros, Chili peppers
How: Studies show that the chemical compound capsacin, found in peppers, speeds up your heart rate and metabolism.  Eating a very spicy meal can actually speed up the metabolism by about 25 percent for up to 3 hours.  Keep Tabasco sauce on the table to spice up everything from scrambled eggs to soup to pasta. 

11.  Pistachios
How: Studies show that pistachios fight weight gain by slowing down rises in blood sugar levels and curbing hunger.  Nut consumption in general is associated with a lower body mass index and has not been associated with weight gain.  Pistachios have a significant amount of protein and are among the highest fiber nuts which slow down digestion, and keep you feeling fuller longer than low-protein, low-fiber snacks.  You also get a lot of nuts for a one ounce serving which helps psychologically.  For a 1-ounce portion of pistachios, you get 49 pistachios versus only 23 almonds and 18 cashews (in an equal one ounce portion). 

12.  Apples and Pears
How:  Overweight women who ate the equivalent of three small apples or pears a day lost more weight on a low-calorie diet than women who didn’t add fruit to their diet, according to researchers from the State University of Rio de Janeiro. Fruit eaters also ate fewer calories overall. So next time you need to satisfy a sugar craving, reach for this low-calorie, high-fiber snack. You’ll feel full longer and eat less.

13. Soup
Eat less and burn fat faster by having a bowl of soup as an appetizer or a snack. According to a Penn State University study, soup is a super appetite suppressant because it’s made up of a hunger-satisfying combination of liquids and solids. In the study, women chose one of three 270-calorie snacks before lunch. Women who had chicken and rice soup as a snack consumed an average of 100 fewer calories than those in the study who opted for a chicken and rice casserole or the casserole and a glass of water.  Just make sure to avoid soups made with cream or loaded with pasta or potatoes.  Aim for broth based soups filled with vegetables for a low-calorie and filling meal or appetizer. Miso soup, vegetable soup and bean soups are all great options.

14. Broccoli
How: Study after study links calcium and weight loss. Broccoli is not only high in calcium, but also loaded with vitamin C, which boosts calcium absorption. This member of the nutritious cabbage family also has plenty of vitamin A, folate and fiber. And, at just 20-calories per cup, this weight-loss superfood not only fights fat but also contains powerful phytochemicals that boost your immunity and protect against disease.  Try it chopped in your salad, or sautéed and used in an omelet or as a side dish.

15. Garlic
How: Garlic is a blood thinner but also seems to have the ability to break down fat. Most people can take it or leave it, but by adding garlic to your diet, even in amounts you cannot detect, will help you in your fat-burning goals and get a number of other benefits. Garlic is also a diuretic.

Are Hot Flashes Holding You Back?

Monday, March 9th, 2009

tanya_zuckerbrotEighty-five percent of the women in the United States experience hot flashes as they approach menopause. Researchers suggest that women with higher body weights actually have more hot flashes that their leaner counterparts. It is believed that hot flashes may be the body’s attempt at dispersing heat, but unfortunately fat seems to act as insulation that prevents the heat from spreading, which usually causes overheating to take place.

Therefore, studies have shown that women who followed a low-fat diet high in fiber-filled foods like fruits, vegetables and whole grains experienced fewer hot flashes than women who didn’t. Below is a list of foods that can help you reduce your symptoms:
 
1. Fiber: Recent research has suggested that no other method enhancing regularity has the same effect as fiber.  Fiber absorbs the estrogen, which relieves hot flashes by reducing the amount of estrogen reabsorbed from bile salts released into the intestine to be mixed with stool. It is recommended that women should be consuming 25-30 grams of fiber daily. Enjoy fiber-rich foods throughout the day such as whole grain breads and cereals, apples, pears, broccoli and cauliflower. 

2. Calcium: The National Institutes of Health recommends that menopausal women get 1,000 mg of calcium daily. Calcium cleanses excess estrogen from the liver, making this nutrient vital in reducing hot flashes.  Calcium-rich foods include low-fat milk, low-fat yogurts and low-fat cheeses. 

3. Soy: Recent studies have found that soy, which is rich in phytoestrogens like isoflavones, can also help reduce hot flashes, as well as night sweats and other menopausal symptoms. Opt for tofu, edamame or any other variety of soy beans, as well as low-fat soy yogurts and cheeses.

4. Beans: Almost all beans — not just soy — contain two important compounds; genistein and daidzein.  Which are known for being estrogenic, helping to control hot flashes and other discomforts of menopause.

5. Omega-3 Fatty Acids: New research from the American Journal of Clinical Nutrition shows a common food compound found in omega-3s can ease hot flashes. Salmon, shrimp, walnuts and tofu all contain high levels of omega-3s. 

6. Vitamin E: According to the National Cancer Institute, studies suggest increasing your intake of vitamin E. Vitamin E replenishes necessary electrolytes lost through perspiration during hot flashes.  Mango, sweet potatoes, almonds, peanuts and sunflower seeds are all great sources of vitamin E.

7. Vitamin B: This essential vitamin has been shown to help reduce hot flashes.  Foods like bananas, pistachios, fish, meat, eggs, bananas, beans and whole grains are all wonderful sources of vitamin B.

8. Vitamin C: One study showed that increasing your intake of vitamin C which contains bioflavonoids; a powerful antioxidant, reduced hot flashes. Grapefruit, oranges, potatoes, broccoli and pineapple are all fabulous sources of vitamin C.

9. Water: Drink a lot of water. Drinking water restores fluids lost to perspiration during hot flashes and can even prevent or minimize the hot flashes themselves.

10. Foods to avoid: Certain foods like, alcohol, caffeine, excess sugar, high-fat meat products and spicy foods rank among the top aggravators of these frustrating episodes.

Tanya’s Tasty Tips: Is Caffeine Helpful or Harmful?

Thursday, October 9th, 2008

Caffeine has become a necessity for all different types of individuals. Whether jump starting your day, staying late night hours at work or just going about your typical day, everyone seems to rely on caffeine in this fast-pasted society we live in. Although in the past, caffeine has gotten a bad rap; recent studies show that caffeine may actually be good for you.

Caffeine is a drug that is naturally produced in the leaves and seeds of many plants. Caffeine is defined as a drug because it stimulates the central nervous system, causing increased alertness.  Most experts agree that moderation and common sense are the keys for eating or drinking caffeine-containing products. Moderate caffeine consumption is considered to be about 300 mg, which is equal to 3 cups of coffee.
 
Here are some surprising health benefits of caffeine:

• Mental Performance: If you are falling asleep and need a boost caffeine can definitely help you.

• Mood: Studies have shown that when people consume caffeine, they felt an increased well being, happiness, energy and sociability.

• Physical Performance: Caffeine helps the body burn fat instead of carbohydrate and dulls the perception of pain, which can both boost endurance.

• Headaches: Most headache medications include caffeine. When you get a headache the blood vessels in your brain expand; caffeine causes blood vessels to constrict which helps relieve pain.

• Diseases: Caffeine has been said to protect against gallstones by showing that caffeine can reduce the size of the crystallized stones. Caffeine can also protect against Parkinson’s disease.  This disease results when levels of the brain chemical, dopamine fall, interrupting nerve signals from the brain to muscles. caffeine increases the expression of dopamine receptors in the brain

• Antioxidants: Many caffeine-containing beverages, most notably tea and more recently coffee, have been found to contain antioxidants. Antioxidants have been known to help prevent heart disease and cancer.

Due to the ever growing consumption of caffeine, manufacturers have been producing more products containing caffeine in them. So if you’re not a coffee addict, here are some surprising boosts of caffeine:

• Edys Grand Espresso Chip Ice cream,(4 oz.) 45mg
• Haagen-Daas Mocha chip, regular or light, (4 oz.) 30-40mg
• Crackheads Candy,(1 package)120mg
• Hershey’s Special Dark Chocolate Bar, 20mg
• Sumseeds Sunflower seeds,(1 container)140mg
• Swiss Miss Mocha Cappuccino,(1 packet) 25,mg
• chocolate milk,(8 oz.) 2-7mg
• Mountain Dew,(12 oz) 54mg
• Red Bull, (8 oz.) 80mg

Drinking Red Bull May Have Killed A Supermarket Worker

Friday, April 25th, 2008

A 40-year-old supermarket worker died of a heart attack after drinking as many as four cans of Red Bull energy drink each night, the Daily Mail has reported.

Pathologist Dr. Ian Roberts said this week Alfredo Duran, 40, of Wheatley in Oxford, England, had an enlarged heart and the excessive caffeine he consumed each day may have contributed to his death.

“My feeling is — given the evidence available — it was a cardiac arrest possibly contributed to by subtoxic caffeine ingestion,” Roberts told the Daily Mail.

Each can of Red Bull is said to contain 80mg of caffeine — about the same amount as a cup of coffee.
