Summer Super Foods

Tuesday, July 28th, 2009

tanya_zuckerbrot2TOMATOES

Summer dish: Sliced tomato with balsamic vinegar
Nothing says summer like vine ripe tomatoes. Tomatoes naturally lend themselves to health-conscious summer cooking, being sweet, yet low in calories. In fact, tomatoes are one of the most frequently consumed “vegetables” in the United States, whether raw, steamed, fried, stewed, crushed, pureed, or reduced to a sauce. (Though thought of as a vegetable, tomatoes are botanically classified as fruits.) They are also one of our best sources of vitamin C, a powerful antioxidant.

They also contain beta-carotene and several other carotenoids that may have their own disease-preventing properties, particularly against heart disease and cancer. One carotenoid, lycopene, may help reduce the risk of prostate cancer. Tomatoes also offer a good dose of potassium, which helps to reduce the risk of stroke.

SALMON

Summer dish: Simply grilled on the barbeque
Summer marks the beginning of salmon fishing season and the time of year when fresh salmon is again available in your local markets. Salmon is low in calories and saturated fats and high in protein. Wild salmon is one of the best sources of health-promoting fats known as the omega-3 fatty acids. Omega-3s promote cardiovascular health, brain health and provide anti-inflammatory protection.

Cardiovascular health: omega-3’s prevent platelets in the blood from clumping together and sticking to the arterial wall in the form of plaque. They also drive down triglycerides and LDL (bad) cholesterol.

Brain health: Omega-3’s interact with the fatty layers that surround brain cells and help protect brain cells from the diseases of aging, like Alzheimer’s.

CORN

Summer Dish: Corn on the cob
Is there anything more satisfying at a summer bar-b-que than an ear of hot corn on the cob? In addition to being sweet and satisfying, there are many health benefits of corn.

One cup of corn provides 18.4 percent of the daily recommendation of fiber. Its high-fiber content is one of the biggest benefits of corn. Fiber has been shown to help lower cholesterol levels and help reduce the risk of colon cancer. Fiber is also useful in helping to lower blood sugar levels in diabetics.

Corn is a surprising source of several vitamins, including folic acid, niacin and vitamin C. The folic acid in corn is now known to be an important factor in preventing neural-tube birth defects. It’s just as important in preventing heart disease, according to studies that show folic acid can prevent a buildup of homocysteine, an amino acid in the body.

SUMMER SQUASH

Summer Dish: Sautéed or grilled squash
Summer squash contains vitamin C as well as beta-carotene, folate and fiber. These nutrients make summer squash a tool in preventing cancers, heart disease and diseases caused by inflammation such as arthritis and asthma.

Whether you’re trying to lose weight or just adopt a healthier eating program, summer squash’s rich fiber content can help you get full faster — and give you many of the nutrients you need.

You Are What You Eat

Thursday, June 11th, 2009

tanya_zuckerbrot2As the saying goes “you are what you eat.” Sure, we all know that if we eat too many fried, fattening foods we will gain weight and probably not feel too great. But did you know that by choosing certain foods, you can actually change your appearance from the inside out?  Foods high in phytochemicals, antioxidants and certain fats all contribute to glowing skin, shiny hair and strong teeth and nails. 

For Smooth Skin:
Vitamin C found in citrus fruits, broccoli, peppers and berries activate fibroblast cells, which makes collagen. The healthier your collagen, the firmer and smoother your skin looks. Keep in mind, studies have shown that women who are deficient in vitamin C tend to bruise much easier.  Eat dark orange, red or green fruit and veggies which are filled with beta-carotene, an antioxidant that converts to vitamin A, which is imperative for producing new and young-looking skin cells.

For Shiny Hair:
Fill your plates with lean proteins like turkey, chicken and egg whites. Hair is made up of protein called keratin, so it makes sense that getting enough of it is essential for healthy, beautiful locks.

In addition, the mineral biotin found in eggs, almonds, bananas and strawberries helps to produce keratin, which has also been shown to prevent graying and hair loss.

For Pearly Whites:
Not only does calcium create cavity-resistant tooth enamel, but it also helps maintains the enamel so teeth stay strong. Aim to consume three servings of low-fat dairy products daily, such as low-fat cheeses, yogurt and skim milk. For all you lactose intolerant people, don’t fret — broccoli and strawberries contain as much calcium as their dairy counterparts.

For Nice Nails:
Zinc, more commonly known as “the acne terminator” also helps keep nails strong and prevent white spots. Great sources of zinc are oysters, eggs and nuts. Load up on spinach, broccoli, lettuce and avocado — which are all filled with folic acid. Folic acid is necessary for nail growth and strength.

** Not only does water help to move toxins through and out of your body more quickly, it also keeps skin plump and dewy, and prevents hair and nails from becoming dry and brittle. For an additional bonus, drink Fiji Water which is the only water that contains natural minerals like silica. Silica improves the condition of hair and nails, the texture and resiliency of skin, and is needed to make strong healthy bones and to keep your blood vessels elastic.

Potatoes Done Right

Monday, May 11th, 2009

tanya_zuckerbrot2Potatoes are healthier than people think. Potatoes contain more potassium than a banana, vitamin C, fiber and even protein. The only problem is that many people often prepare potatoes in unhealthy ways. People mostly choose to fry them up, drown them in cheese or mash them with fattening butter and cream and since potatoes don’t contain fat or cholesterol, why would you add it to them?

Stuffed Baked Potato:
The key is to look for healthy toppers. Filling your baked potato with vegetables is a healthy way to add even more vitamins, without adding fat. Instead of using full-fat sour cream, mozzarella cheese or cheddar use their low-fat or fat-free alternatives to save on half the calories and fat. Use salsa for a bold topper —  you’ll crank up your metabolism. Capsaicin, the substance that gives kick to peppers and chilis, has a thermogenic effect, meaning it causes the body to burn extra calories for 20 minutes after you eat them. 

Baked Fries:
A typical serving of French fries — which usually takes a bath in vegetable oil — can contain about 600 calories. Your healthiest bet would be to spray Pam calorie-free, non-stick cooking spray on a roasting pan. Slice your potatoes and add salt and pepper and any seasonings you like. For a metabolism kick try making spicy fries. Studies have shown that spices like cayenne pepper can speed 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.

Mashed Potatoes:
This is one of the most classic comfort foods, however once it is mashed with butter and cream and the gravy is poured on top, you have a creamy bowl or artery clogging fat. Most of the nutrients that are found in potatoes are located in the skin. Therefore to increase the amount of vitamins and minerals, leave the skin on. Use skim milk, roasted garlic and onions, and a little parmesan cheese instead of whole milk and butter.

Potato Salad:
What’s a party without a potato salad? One cup of this salad contains as many calories as half your daily requirement.  Food for thought, one tablespoon of mayonnaise contains 90 calories and 10 grams of fat. Let’s be honest, usually the potatoes are dripping in mayonnaise. For a creamy, rich flavor and an added boost of protein, use non-fat Greek yogurt as the base to save on half the calories and fat. If you must use mayonnaise, switch to low-fat versions. Substitute an artificial sweetener like Splenda in place of sugar. Add chopped veggies for an added boost of fiber, vitamins and minerals.

Soups:
Instead of opting for a creamy-based potato soup, opt for a broth-based hearty vegetable one. The hearty mix of potatoes and other vegetables will fill you up on few calories. You can also add in some lean meat for a hearty fiber-filled meal that will keep you full without filling you out.

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.

Holiday Skin: Tips Look Your Best This Season

Thursday, December 4th, 2008

82x104_sadickWith Thanksgiving behind us, we are quickly approaching the holiday season!  There are several skin and body care tips that can help keep you looking your best, while at the same time, keeping your skin healthy and young.

Whether you go on vacation this year or stay near home, you are always exposed to ultraviolet rays when outdoors.  With innovation and advanced technology, we have changed the paradigm to protect your skin against harmful sun damage, free radicals and environmental toxins.  I believe that the best protection is achieved by using a broad-spectrum sunblock (that protects against shortwave UVA and longwave UVB light) along with a high-potency antioxidant cream (containing active agents such as resveratrol, idebenone and vitamin C, and coffeeberry).

Whether you are skiing with your family or on the beach enjoying the sunshine, do not forget that the strongest sun exposure occurs between the hours of 12 noon and 4 pm.  These are the times you should minimize your sun exposure.  If you get sunburned, new red light LED sources are available from your dermatologist that can accelerate healing, reduce redness and decrease the potential for damage to your skin. 

During the winter holiday season, especially in colder climates, our skin gets drier.  So it’s important to stay away from hot showers which dry the skin and to be sure to apply generous amounts of moisturizer to your entire body while your skin is still damp. Moisturizers with SPF are always a good bet because they automatically protect your skin.

There are also several procedures that can make your skin look better with no downtime.  It may be a Botox treatment, filler treatment with Restylane, Juvederm, Radiesse or new generation collagen fillers such as Evolence that can get rid of those unwanted folds and lines.  These will all give immediate results and give you a refreshed, youthful appearance.

To make your skin look fresher, consider a light chemical peel, laser peel, microdermabrasion or an Intense Pulsed Light (IPL) photo rejuvenation treatment.  These are all easy, virtually painless, and have little to no downtime.  But remember; you should do such treatments at least two weeks before a big event or celebration.

He is a Professor of Dermatology at Weill Cornell Medical College and President of the Cosmetic Surgery Foundation. Dr. Sadick is author, or co-author, of more than 500 articles in peer-reviewed scientific journals and has contributed more than 75 chapters of medical books. Read more at www.sadickdermatology.com.

Dr. Manny’s Notes: From Plantains to Pumpkin

Wednesday, July 16th, 2008

Plantains, though they look very similar to their cousin, the banana, are actually quite different and act more like potatoes; they must be cooked prior to eating. Throughout Latin America, plantains are more than just wonderful additions to soups and stews. Unlike potatoes, these treats can be used in all stages of ripeness—from green to almost black! Plantains do not contain any cholesterol or sodium and are low in fat. They contain a good dose of calcium, iron, and potassium, are high in vitamin A, and provide an excellent source of fiber.

Pumpkin, another ubiquitous vegetable found throughout Latin America, is full of taste and health benefits! Whether it’s steamed or baked, or added as a flavorful thickener to all kinds of soups and rice and bean dishes, it makes a delicious and healthy addition. Though low in calories, its bright orange flesh is rich in antioxidants and carotenes, as well as potassium and vitamins C and E. It may lower cancer risk, heart attacks, cataracts, and strokes.

Dr. Manny’s Notes: Latin Powerfood #5 – Cinnamon

Wednesday, July 9th, 2008

SPICE IS LIFE: One of the things that makes this diet so healthful is its use of herbs (fresh whenever possible) and spices that complement the ingredients and add depth without the fat. This trick–the less fat and more flavor trick–has been traditionally practiced in Latin America for centuries. It’s the technique of using sprinkles of cumin, oregano, and cilantro, which add not only taste but also health benefits. In fact, cumin, which is a great replacement for salt in many dishes, has been found to have ten times the antioxidant power of vitamin C. And it could also help protect against cancer.

Which brings me to my next powerfood on the list…CINNAMON!

A half teaspoon a day of cinnamon can lower sugar levels in your blood, and studies show that cinnamon can aid in the prevention of diabetes. Cinnamon is also high in antioxidants, not to mention flavor. You can sprinkle cinnamon on fruits or whole grains instead of sugar for a delicious treat. You will also benefit from its sensually warming and cholesterol-lowering qualities. First used medicinally in Egypt and India and in parts of Europe since about 500 BC, this spice is now part of many Latin American and Caribbean cuisines.
