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.

Red Meat in Moderation

Wednesday, March 25th, 2009

siegel1My “beef” with a study just released in the Archives of Internal Medicine on the supposed dangers of red meat is not with the study itself, but with the conclusions that we might too easily draw from it.

We are a society that looks for bad guys. Rather than improve our overall diet and exercise more regularly, and live a healthier lifestyle, we look for culprits, health criminals that we can blame.

Cigarettes are an obvious target, and cigarettes deserve our medical scorn. Alcohol too, though in recent years we have been trying to give limited amounts of alcohol a respected place (not entirely successfully) in a healthy lifestyle by pointing to its affects at improving circulation. Red meat, on the other hand, has always been seen as unhealthy, though acceptable in limited amounts.

Now along comes a new study from the National Cancer Institute and National Institutes of Health published in the Archives of Internal Medicine looking at how half a million men and women ages 50 to 71 showed a modest increase in mortality from cancer, heart disease and other causes associated with high portions of red meat and processed meat.

The study attempted to control important variables such as exercise and overall diet, but in my opinion, it is very limited because of its survey design. It’s not prospective or randomized, despite large numbers. Epidemiological survey studies like these are preliminary; they need to be followed up by many vigorous, scientific studies before any firm conclusions are drawn.

Though white meat may be preferable, it is also not clear what may have caused the differences in mortality in the study. It may not be the red meat itself but could be the fat, or the steroids, antibiotics, and other chemicals we regularly pump into our meat.

Remember, red meat contains many essential vitamins, including C, D and B12, and is a major source of iron and protein. It is an important source of nutrition for many who would not or cannot afford to get it any other way. Red meat may be especially important for those who are anemic, and for pregnant women.

The bottom line here — red meat in moderation is still safe, but limit portion size and eat a well-balanced diet whenever possible. You can find the same kind of sage advice on the blog of our knowledgeable dietician, Tanya Zuckerbrot, and in the pages of The Hot Latin Diet, written by our esteemed health editor, Dr. Manny Alvarez.

Diet Myths Debunked

Thursday, March 19th, 2009

tanya_zuckerbrot5MYTH: EATING AFTER 8 CAUSES WEIGHT GAIN
The reason most people think that eating at night causes weight gain is because people tend to eat extra at night, not taking into account what they have already eaten during the day. Well, the way it works is that at the end of the day, the more calories you eat, the more weight you gain — regardless if it’s during the day or at night.  Even the healthiest foods, when eaten in greater amounts than needed for energy, will be stored as fat. It is not possible to circumvent the laws of thermodynamics and energy balance. It all comes down to calories in vs. calories out.
However, the reason most people do gain weight from eating at night is because they have a late dinner after not eating for a long period of time. This makes it hard to make good food choices and also to keep portions in control. You may end up picking up a slice of pizza or two whereas if you weren’t as hungry you would have time to cook a healthy dinner without sabotaging your diet.

The second concern that comes with late night eating is “mindless” snacking in front of the TV or hanging out with your buddies. People tend to pig out on ice cream, cookies, or pizza (not on celery and carrots) and this leads to weight gain because it is usually extra calories taken in.

So aim to spread your calories throughout the day and if you do have to eat a late dinner, don’t worry about it leading to weight gain as long as you have not overeaten during the day.  Try and eat most of your carbs during the day (carbs are used for energy so eat them at breakfast, lunch and snack to fuel your activities: work, school, gym, etc). At night, focus on eating protein and vegetables since most likely your lying around and don’t need the energy from carbs.

MYTH: SUGAR MAKES KIDS HYPER
This is a huge myth. It has even spawned a popular phrase:  “sugar buzz.” But when researchers put it to the test, they found no evidence that sugar led to hyperactivity in kids or adults. Researchers found that hyperactivity of children at parties or any type of festivity is from the environment they are in. In fact, in one study published in the New England Journal of Medicine, they gave some kids sugared foods and gave others foods with artificial sweeteners. Their parents and the researchers didn’t know who was eating sugar and who wasn’t. They monitored the kids for things like irritability and hyperactivity and they found no difference. 

Another cause for hyperactivity could be from caffeine found in soda or even chocolate. Sugar may have an effect on kids with established hyperactivity, but it won’t make a non-hyperactive child become hyperactive. All sugar will do will increase your energy level, but it won’t cause hyperactivity. Many people still blame sugar for their children’s “wild” behavior, but technically speaking there is no science that proves this.

Any food that affects blood-sugar levels can create an adrenaline surge, which will lead to a burst of energy. However, many kid-favorite, sugary snacks are lacking fiber which is the  reason why your child may become hyperactive.  So if your child is often bouncing off the walls of your home, simply swapping an orange for orange juice or high-fiber cereals for sugared varieties, will keep their blood sugar levels normal.

MYTH: SWALLOWED GUM STAYS IN YOUR BODY FOR 7 YEARS
For the most part, gum is as indigestible as a paper clip. Gum is made from gum resin, flavoring and sweeteners. The human body cannot digest gum resin. Many of us were told as children that it would stick to our insides for seven years, but that is absolutely not true. Our bodies move indigestible material through our digestive systems and out of our bodies in bowel movements.

Many people don’t realize this, but chewing gum can cause bloating because it causes you to swallow air. All that air gets trapped in your GI tract and causes pressure, bloating, and belly expansion.

There is absolutely no nutritional benefit to gum. Sugar-free gum often contains sorbitol. Sorbitol is a sugar substitute that acts as a laxative, which draws water into the large intestine. As little as four sticks of sorbitol-containing gum can cause bloating and abdominal pain.

MYTH: ORGANIC FOOD IS HEALTHIER THAN CONVENTIONAL FOODS
According to The Institute of Food Technologists, organic food is no healthier than conventionally grown foods. Organic food means that its ingredients were grown without chemical pesticides, fertilizers or insecticides. It’s healthy because there are no chemicals, but organic doesn’t necessarily mean the food is nutritious.

Of course, even organic or all-natural food can pack on pounds. So be careful you don’t get carried away.  Take organic potato chips and cookies for example. Over eating these will still make you fat!

Considering organically-grown food can cost more than twice as much as conventionally-grown food, sticking to a diet rich in whole grains, lean protein, fruits and vegetables is your best bet to your healthiest and happiest diet.

MYTH: RAW VEGETABLES ARE ALWAYS BETTER THAN COOKED VEGETABLES
Not so. The amount of nutrients you get from vegetables can differ for a number of reasons, such as how long you store them and how (or if) you cook them. Although cooking vegetables can lose nutrients, cooking can sometimes increase the amount of nutrients available to the body. An example of this is the antioxidant lycopene in tomatoes. Cooking tomatoes releases more lycopene than is available in raw tomatoes.  In addition, in January, a report in The Journal of Agriculture and Food Chemistry concluded that cooking carrots, zucchini and broccoli was better than eating them raw.

Loss of nutrients can occur in cooking because some vitamins, like vitamins B and C, dissolve in water. Some can be lost if the vegetables are boiled for too long. Steaming or stir-frying helps retain the vitamins when you cook vegetables. The fact of the matter is vegetables are powerhouses of nutrition, no matter which way you eat them. Whether raw or cooked, five servings of vegetables a day are recommended for good nutrition.

MYTH: CARBS MAKE YOU FAT
One of the greatest diet myths is that carbs make you fat.  Nothing can be further from the truth. If the only thing you ate all day was a bagel, that bagel would not make you fat.  It’s not that carbohydrates make us fat; it’s the quantity we eat which packs on the pounds. For example Italians live on pasta. Yet they eat pasta as their starter-primo piatto, which consists of 1 ½ cups equaling 375 calories. Then they follow with a segunda or main course of lean meat or fish and vegetables.

In the United States, on the other hand, we most often eat pasta as our main course. A typical main course serving of pasta in this country is about 4 cups, or 1,000 calories. Big difference! 

The secret to eating carbs and shedding pounds is eating high-fiber carbohydrates. Fiber is the zero calorie, indigestible component of carbohydrates. The more fiber a food contains, the less digestible carbohydrate there is. It is the net carbohydrate, not the total carbohydrate that gets converted and stored as fat.  High-fiber carbohydrates have lower net carbohydrates than foods that contain no fiber. In addition, fiber adds texture, bulk and chewing satisfaction, which aids in consuming fewer calories, yet still feeling full. Choose whole grain breads, cereals, fruits vegetables, and legumes to fill your tank without gaining weight.

Is Your Doctor Prescribing Placebo Treatments?

Monday, October 27th, 2008

The National Institutes of Health recently published an interesting study in the “BMJ,” where they approached 1,200 internists and rheumatologists about what they called “placebo treatments,” where patient expectations rather than an expected physiological response was the rationale for the treatment. Only 679 physicians responded, which limited the conclusions, along with the design of the study itself, as this type of survey is a weak form of science. Nevertheless, the results were disturbing – about half of the responding doctors indicated they prescribed these kind of treatments on a regular basis, and more than 60 perecent believed there was no ethical problem in doing so. It has long been known that cures and responses to treatment can be affected by a patient’s mental attitude and expectation, and that healing itself involves suggestion as well as chemical intervention.

But I find these results deeply disturbing for the following reasons:

1) Most of those surveyed were not using sugar pills or harmless salt water, they were using medicines with potential side effects. These included over-the-counter analgesics (41percent), vitamins (38 percent), sedatives (13 percent), and antibiotics (13 percent).

2) More than 90 percent of upper respiratory infections are viral, yet physicians are knowingly prescribing antibiotics to meet patient expectation.

3) Patients are fueled to ask for pills because of advertising, the Internet and a culture of instant gratification.

4) Physicians are motivated to provide a quick fix rather than a more elaborate explanation which could eliminate the need or urge for the treatment. A study published in the “Annals of Family Medicine” published in 2005 concluded that physicians only spend 55 percent of their time in face-to-face patient care. In this environment of 5 to 10 minute office visits, it is often easier for doctors to provide a quick placebo treatment rather than a more elaborate diagnosis and explanation.

5) This is a survey of doctors, but it is highly doubtful to me that patients would be satisfied with this approach. I suspect that a similar survey of patients would reveal that less than 10 percent of patients believe that it is okay for placebo treatments to be given for deceptive reasons, with false expectations. I suspect that most patients would like an interaction with their doctor to be completely honest and based on full disclosure.

Do my readers agree?

Allergy Alert: Getting Rid of Puffy Eyelids and Dark Circles

Tuesday, September 30th, 2008

There isn’t a day goes by that I do not get questioned about a patient’s facial appearance that includes puffy eyelids, dark circles as well as wrinkles.  We let’s face it; our looks are of great interest and concern.  I recently had a chat with dermatologist Dr. Bobby Buka, section chief in the Dept. of Dermatology at Mount Sinai School of Medicine in New York City about this. 

“Puffy eyes are progressive,” he said.  “As we age, we all lose fat pads (called subcutaneous tissue) that rest below our eyes. These dark circles that may appear underneath your eyelids and can be visible as a discoloration or bluish color with puffiness of the eyelids is actually blood coursing through veins beneath.”

Buka also mentioned that getting enough water and fluids optimize “hydration”, and this is very critical.  Doing this can replenish the deeper layers of the skin with water delaying drooping of skin, and improve the appearance of dark circles.  Avoiding dehydration can help to decrease the effect of gravity as adequately hydrated skin tends to sag less with advancing age! Buka also recommends a well-balanced, high-vitamin diet.

Those affected by allergies, particularly children and young adults, may have the presence of a horizontal crease on the middle part of the nose.  This may reflect persistent upward “rubbing” of the nose from itchiness and explain the appearance of a nasal “crease” associated with allergies, especially if your allergies are not adequately controlled or treated.  In other words, get proper therapy for your allergies so you can feel better and look better!

Toxic Vitamins: Before you pop that next pill, read this

Monday, April 21st, 2008

Health officials are investigating more than 180 reports of illness in people who took dietary supplements containing toxic levels of the mineral selenium.

Last month, federal officials warned consumers about harmful doses of selenium, a mineral considered healthful in small amounts — in plastic bottles of liquid Total Body Formula and Total Body Mega Formula.
