Dear A Sip of Calm,
Can we actually find relaxation in a can? Seems like it could be a great idea, unfortunately, at this point in time, it's just too good to be true. Just like herbal supplements, the FDA does not require companies manufacturing the "relaxation beverages" to prove their claims or standardize their ingredients. As such, there is no conclusive scientific evidence that any of these products are safe and effective. What little research has been done has shown that many compounds in these drinks, such as 5-HTP and melatonin, degrade in water. Other ingredients such as GABA, cannot cross the blood-brain barrier so are completely ineffective. One study even tested five popular brands and found that many of the ingredients listed were barely even present in the drinks themselves!
Two popular ingredients in relaxation beverages that have been studied are valerian and kava and the news is not good. Valerian can cause dependency if taken regularly while kava has been shown to cause liver damage. These types of ingredients can also interact with medications such as Allegra or benzodiazepines (Xanax, Valium, Atvian, etc.) or even with Tylenol and cause serious health problems.
What's your best bet for relaxation? For starters, maintaining a proper diet, exercising, and trying to keep a regular sleep schedule can contribute to feelings of relaxation. You may also want to try meditation and/or yoga.
In the end, it seems as if nothing beats a glass of warm milk or hot (decaf) tea to unwind in the evening.
First of all, the fact that you are reaching out for help takes lots of strength and is incredibly brave. It is also a very good sign for recovery. Your willingness to attend the eating disorders group at Columbia, visit Barnard Health Services, talk openly with your therapist and your parents, and write here, shows a lot of determination and courage, qualities which have probably gotten you through other challenges previously in your life.
Your questions about various forms of treatment are good ones. Most studies put the recovery rate for outpatient treatment (what you are currently receiving) at about 60 to 70%. Studies indicate that the vast majority of hospitalized patients respond favorably to treatment. However, (and this is what your therapist may be referring to), there are high relapse rates following hospitalization (30 to 50%) so what happens after hospitalization is crucial to maintaining the benefits. Relapse rates for outpatient treatment aren’t available because it’s often so unsuccessful in the first place, that it’s too tricky to accurately measure relapse rates. The fact that the data is skewed in this way may make hospitalization look less effective than it is. If your gut is telling you that it’s time for hospitalization, keep fighting for it. Tell your parents and therapist that you think it is best for you right now. They need to understand that you have a potentially life threatening condition. It is not your fault. It’s not a character flaw. You deserve treatment.
Hospitals that treat eating disorders do so holistically. Anorexia needs to be addressed from a nutritional, bio-chemical, psychological, and social perspective. They have you work with psychiatrists, psychologists, dieticians, gastro-enterologists, endocrinologists, and other health care providers. Any co-occurring issues such as substance use, depression, body distortions, etc. need to also be addressed, and hospitals that treat eating disorders understand this. When people are released from the hospital, it can feel like a significant loss of structure and support. Therefore, it is important that you, the hospital, your parents, and therapist plan for this and have such structures in place.
Research indicates that a combination of individual therapy, group therapy, and family therapy (if you’re living with your family), plus visits with a dietician and medication (often antidepressants) can prevent relapse. Individual therapy should specifically be cognitive behavioral therapy, preferably with a clinician that has had specific training in treatment of eating disorders. And it’s important to know that even in cases of relapse, you can bounce back. When people learn new behaviors and new ways of thinking about themselves, mistakes are almost inevitable and should be expected, because you are changing patterns that are firmly etched into your way of being. As a Barnard student, you have many rich resources around you. For instance, Barnard students can make an appointment to see a professional counselor at the Rosemary Furman Counseling Center.
As far as insurance goes, it may be a good time to have a heart-to-heart with your parents. Let them know how you feel and share any information or research that you have found. The National Eating Disorders Association has specific information on insurance coverage and how you and your parents can discuss what is and is not covered with your insurance company. Your willingness to seek out help is a real strength and will likely inspire other readers. So thank you. For more resources on eating disorders, see these resources and the related Q&As below.
Dear Long Cooker,
Whether you’re an avid chef or a microwave maven, it is important to know that overcooking can deplete the amount of vitamins and minerals in foods. If you are cooking your pasta and beans for as long as you say, you are most likely losing some of their nutritional value. Overcooking destroys bonds between molecules, significantly depleting the nutritional value. For example, overcooking can destroy amino acids and many of the B vitamins, such as Vitamins B-1 and B-5. These vitamins are important for metabolism and energy production.
Generally, shorter cooking time retains more nutrition in a food. Here are a few basic cooking guidelines for your pasta and beans:
Beans, peas, and lentils (members of the legume family) are low in fat and high in fiber, making them a healthy part of your diet. Cooking your beans properly can make them a nutritious and delicious addition to a meal. Dried beans should be soaked overnight in fresh water. They are then cooked for 1-3 hours, depending on the variety of bean. This is standard preparation, and beans cooked in this manner are full of nutrients.
Pasta is a complex carbohydrate, with more fiber and a lower glycemic index than simple sugars. Overcooking pasta can strip it of its fiber content. Most pasta only needs to be boiled between 5 and 15 minutes, depending on the cut of the noodle. Overcooking pasta will only add to the loss of vitamins (especially water-soluble B vitamins) and minerals that occurs when you cook it. Another tip: try not to rinse cooked grains and pasta, as this causes further loss of nutrients.
The style of cooking plays an important role in the overall nutrition of food as well. Whether fresh, steamed, baked, grilled, boiled, or fried, how food is prepared can modify the nutritional content. For instance, boiling leeches more nutrients out of vegetables and beans than baking, as many of the vitamins in vegetables are water-soluble. Steaming and microwaving your food can help maintain the most nutrients.
While it appears that androstenedione has helped some people (a few prominent athletes included) increase their muscle mass and recover more quickly from injury, there is no scientific research supporting these results. In order to help you decide whether such nutritional supplements are right for you, let’s first take a look at androstenedione.
Androstenedione is a direct precursor hormone to testosterone and other hormones including one type of estrogen. It is converted from cholesterol, as are all other steroid hormones. Specific enzymes and hormones, among other things, must be present and ready to work for these conversions to take place. For instance, luteinizing hormone, produced and released by the pituitary gland, plays a pivotal role in converting androstenedione to testosterone. Simply introducing extra androstenedione to your system does not automatically indicate that all of the necessary players will be there to produce testosterone or improve the productivity of your workout.
About sixty years ago, when androstenedione was first synthesized, it was shown to have both androgenic (male hormone-like) and anabolic steroid-like properties. The anabolic effects were considerably less than those of testosterone. Subsequent research found that testosterone levels rose after inhalation of androstenedione, but remained elevated for only a couple of hours, with peak levels lasting a few short minutes.
Beyond these cursory early studies, rigorous studies have come to two broad conclusions about androstenedione. First, despite increasing testosterone levels for those with low baseline testosterone levels such as women and older men, androstenedione has not been shown to increase the testosterone levels of young men or to improve the effectiveness of their exercise regiments aimed at building muscle.
What side effects can you expect from androstenedione? No one knows for sure. Androstenedione falls under the category of steroid hormones, which are known to have androgenic and anabolic properties. Therefore, androstenedione may produce side effects similar to those of testosterone-based anabolic steroids. The most dangerous of these side effects is the increased risk for cardiovascular disease, certain cancers, depression, psychoses, and even extreme aggression. There are also gender-specific effects. For men, these include shrinking testes, increased hair loss, enlarged breasts, and possible sterility. Women may experience side effects such as shrinking breasts and uterus, enlarged clitoris, irregular menstruation, increased facial and body hair growth, and a deepening voice. In fact, due to many potential negative health hazards, the Food and Drug Administration (FDA) has prohibited the sale of over-the-counter androstenedione and similar steroid-like dietary substances.
Is it safe? Safety can be difficult to determine when you don't really know what you're dealing with. Is it worth the risk? That's for you to decide. Before you begin taking any dietary supplements you may want to speak with your healthcare provider. S/he can answer your questions and give you more detailed information. Columbia students might want to consider making an appointment at Medical Services by calling x4-2284 or online using Open Communicator. Students on the Medical Center campus can contact the Student Health Service.
Sporting sexy things for one's paramour is one of the many perks (no pun intended) of relationship life. And it is a great testament to your relationship that your boyfriend compliments you. Some wise person once said, however, that "reassurance never reassures." So it is possible that his compliments may not be fully sinking in. In order to accept kind words from others, some part of you must also believe the statement. Have you noticed how you react when he compliments you? Are you able to hear and believe positive comments about your appearance?
It is possible that your low self-esteem, or at least your negative evaluation of your appearance, may affect you beyond intimate situations. Do you think this is true? In the western world, the skinny image of feminine beauty is everywhere. Any young child can tell you what an "ideal woman" should look like and very, very few women fit that standard (which is not culturally universal). Many people have internalized negative beliefs about themselves. These messages did not originate with you: They are the voices of young peers, family members, TV, magazine and billboard ads, and other mass-produced images of a standardized and very specific idea of beauty. Once a person has internalized a negative belief about the self, it can be very difficult to unlearn it, especially if you have held the belief for a long time.
So what to do about it? Here are some strategies to address your self-consciousness:
Gaining more insight. Many psychologists believe that suffering can be alleviated through insight. There are many different kinds of insight: You can gain insight about the source of your pain, insight about how and when it operates currently, and insight about how tour low self–esteem may affect other people. Source insight can be helpful because it can help you understand how and when the view was established. Many believe that people experience a type of liberation when they are able to make connections between early experiences and current thinking. You are able to see that your view of self originated outside of you and may very well be distorted. Gaining more insight into how others view you, you may begin to wonder if your own negative view of self is distorted.
Changing thoughts. Even without gaining insight, people can change their belief systems. Cognitive behavioral therapy is one way in which a therapist can help address distorted thinking or false beliefs that you may have about yourself and about your appearance.
Changing emotions. What are the feelings that come up for you when you undress? Do you experience anxiety? Shame? Fear? What emotions come up when you imagine yourself wearing something sexy for your boyfriend? What emotions do you notice yourself feeling when he compliments you? Do you feel happy? Embarrassed? Doubtful? Another benefit of therapy is that it may help you uncover some these emotions and which may allow you to work on changing them. Sometimes, negative self–esteem can be as much about someone's emotional state as one's thought process.
Fake it 'til you make it. Some psychologists believe that changing behavior is what leads feeling better. If you do the things that you'd like to do, even if they cause anxiety, you may eventually become "de-sensitized," meaning that the negative feelings may become less powerful over time and may be replaced by more positive ones, especially if you have good experiences when you take such risks.
A great deal has been written on the subject of body image and self-confidence. If you're looking for some good reads, here's a list:

Trying to make sense of all the vitamin and mineral supplements on the pharmacy shelves may make you feel stuck between a rock and a hard place! Before you swallow any information, it is important to know that both ionic minerals and colloidal minerals have a lot of dubious marketing and advertising surrounding them. Manufacturers of colloidal and ionic supplements may make a variety of claims about their products — many of which are not confirmed by scientific research. Moreover, the body doesn’t need a whole lot of minerals; fewer than 20 have been judged to be essential to your health.
A colloid is a mixture in which particles are suspended in a liquid or a gas. Colloidal minerals come from humic shale deposits, primarily from Emery County, Utah. After collection, the shale is crushed and placed in water so that the minerals can enter the solution. Colloidal mineral distributors stress the “naturalness” of their product and have made claims about improving conditions associated with certain diseases, a practice judged to be illegal by the FDA. In addition, some advertisements state that colloidal supplements contain 75 minerals, many of which have not been proven to be beneficial to health (such as platinum, gold, and silver).
Ionic mineral distributors state that colloidal minerals have too large of a particle size to be absorbed by the body. Therefore, ionic minerals (named after their supposed positively and negatively charged molecules) were created to have the “correct electrical charge” and therefore lead to higher levels of absorption by the body. Although these supplements may actually lead to greater absorption, it is important to remember that there are various other conditions that must be present in the body in order for this to happen.
In reality, the body only needs minerals in trace amounts. Excessive dosages of minerals can actually be toxic. Therefore, before you experiment with any vitamin or mineral supplements, you may want to speak with your health care provider. A provider can help you sort out fact from fiction, so you can make an informed decision and avoid products that may be harmful or simply ineffective. In certain cases, you may be better off wearing these minerals than ingesting them!

Dear Reader #1 and Marianne in Mesquite, Tx,
The Atkins Diet is a popular low-carb diet, which restricts certain types and amounts of carbohydrates (such as grains, starchy veggies and fruit) and emphasizes protein and fat. The idea behind the diet is that eating too many carbohydrates leads to blood sugar imbalances, weight gain, and cardiovascular problems. The Atkins Diet, in particular, has varying phases of strictness, at first limiting carbs drastically and then gradually increasing your range of foods over time.
So why have you both heard that a low-carb diet might be bad for you? Drastically cutting carbs can result in some not-so-fun side effects such as headache, dizziness, weakness, fatigue, and constipation. You may even experience nutritional deficiencies. Eating a green salad each day might not cut your risk entirely. Carbohydrates are your body’s main fuel source, and digestion breaks down carbs into glucose (blood sugar). Severe restriction of carbohydrates (less than 20 grams a day) can result in a condition known as ketosis. Ketosis happens when your body doesn’t have enough glucose for energy, which leads to your body breaking down stored fat, causing ketones to build up in your body. The side effects of ketosis include nausea, headache, mental fatigue, and bad breath. Low-carb diets may be dangerous for people with severe kidney disease, or for pregnant or breastfeeding women. It’s best to consult your health care provider before starting a low-carb diet, especially if you have diabetes or gout, or take diuretics, insulin, or oral diabetes medications.
Some studies suggest weight loss with the Atkins Diet is not due to cutting carbs, but taking in fewer calories because your food choices are limited and protein and fat may keep you feeling full longer. The key to low-carb diets, or really any diet, is to find a way to balance being healthy (getting the nutrients and exercise that you need) while watching your food intake. Shedding the pounds can mean shedding disease risk! Almost any diet that helps you lose excess weight can improve your HDL cholesterol and triglyceride levels and can reverse risk factors for heart disease, type 2 diabetes, high blood pressure, bone loss, and some cancers.
When considering a diet for weight loss, there’s no famine of options. Check out the Alice’s archives on weight gain and loss for more information on different types of diets and the healthy eating category for more ideas on what to eat. Consider your personal preferences, budget, and health and look for a safe and effective weight loss plan. It can be hard to stick to a restrictive diet in the long term, making it difficult to reach a weight goal. Just because a diet is popular or your friends are trying it, doesn’t mean it’s the best approach for you. Besides speaking with your health care provider, you could also consider weight-loss support groups or speaking with a registered dietitian.
Under the 2010 Affordable Care Act, diet counseling is covered for people at higher risk for chronic diseases like type 2 diabetes and high blood pressure. Depending on your insurance, you may be able to get diet counseling at no cost to you. Check with your insurance provider to find out what’s included in your plan.

There is so much nutrition information available from a host of different sources and it’s not hard to see why confusion can arise. You may have access to information published in scientific journals, which are studies that have been critiqued by nutrition experts. At the other end of the spectrum, some sources such as websites and corporate advertisements are created with the intention of boosting sales of the latest diet book or food product. In order to increase the chances of finding valid nutrition information, it's important to identify, use, and refer back to sources you trust. Additionally, when comparing information from multiple sources it is very important to make sure you are comparing exactly the same thing (same serving size, same source, etc).
When gathering information online, it is important to determine who sponsors the site, how often it is updated, the sources for information, and if advertising is involved (or influences content). As an example; Go Ask Alice! is sponsored by Columbia University, content is updated daily (all pages have an update date listed), the sources are described (see below), and the site is advertising free (learn about our no ad policy).
The U.S. Department of Agriculture (USDA) is generally the most reliable source of nutrition and food-related information for the general public in the United States. The dietary guidelines can be found at their MyPlate website where you can also find sample menus and recipes, a food tracker, BMI calculator, as well as several other useful health and food-related tools.
The USDA also has a National Nutrient Database, which is a reliable source for nutrient values for foods. Frequently, this site is accessed by nutrition researchers and developers of nutrient analysis programs. The National Nutrient Database site is user friendly enough that even regular people will be able to do a food search during her/his first visit to the site. Even the National Nutrient Database site, however, can be confusing. For example, it will generate conflicting numbers for nutrients in products such as milk, which comes in a number of varieties. For example, cow's milk provides 8 grams of protein per 8 ounces, evaporated skim milk provides 19 grams, and soy milk, 3 grams. The lesson learned here is to check the details of the food you searched for if the results seem different. For example, a search for milk could yield information on both coconut milk and cow's milk.
The MyPlate SuperTracker and the Nutrient Analysis Tool (NAT) are comprehensive online programs that can be used to analyze not just one food, but an entire day of food intake. They show a comparison of the analysis to your daily nutrient needs. The food lists in these programs come from the USDA National Nutrient Database, and nutrient needs are based on the Recommended Dietary Allowance (RDA).
RDAs are amounts of nutrients that, if consumed on a daily basis, would meet the needs of approximately 97 percent of the population, and are amounts that have been established after years of intensive research studies. The RDA of protein for adult males is 56 grams per day, and for women it is 46 grams per day. This general recommendation is based on 0.8 grams of protein per kilogram of body weight, for individuals in good general health. Protein needs can vary depending on a person's health status and exercise regimen.
For a personalized assessment of your nutrient needs Columbia studnets can make an appointment with a Registered Dietitian. Columbia University students can call x4-2284 or log into Open Communicator to schedule an appointment. Non-students may have access to a nutritionist through her/his primary health care provider or search for a dietitian in your area through the Academy of Nutrition and Dietetics web site. You might also want to check out the resources listed on the Columbia Health Get Balanced nutrition page.
For additional information regarding finding quality health information online, check out Health information on-line: Whom can you trust? Hopefully these new resources will help to clear up your nutrient value confusion, making it easier for you to make healthier eating choices.
First things first: Great job staying active! Now, on to your very interesting (and slightly complicated) question. As you have already noticed, there are many schools of thought on the issue of maximizing fat loss. Do you exercise on an empty stomach or do you make sure and eat a little something before your morning run? Sifting through all this information can indeed be confusing. Let’s get to the bottom of the issue.
The latest research seems to indicate the following: If you will be exercising longer than 30 minutes, eat a light snack in the morning before you run. It’s a good idea if that snack contains some carbohydrates and some protein (i.e. a banana with peanut butter). This allows your body to use the carbohydrates to help burn fat in your body and the protein will keep you going past that 30 minute mark. However, if your aerobic workouts are less than 30 minutes, exercising on an empty stomach may indeed be the most beneficial for fat-burning.
Carbohydrates are the easiest for your body to burn — they require the least amount of oxygen. Fat, the body’s long–term energy storage mechanism, takes more oxygen. If no carbohydrate is present (i.e. an empty stomach), your body will burn fat for energy. But your body will also start burning protein. Herein lies the catch to performing aerobic exercise on an empty stomach: You may experience some muscle loss, especially if your work out is 30 minutes or longer. Here are a few more things to consider:
- Not eating before a workout may cause you to fatigue faster, thereby shortening or lowering the intensity of your workout.
- Exercising on an empty stomach can decrease blood sugar levels, which may make you hungrier and more prone to overeat at your next meal.
Lastly, individual bodies with different metabolisms do this sugar-protein-fat dance slightly differently. For example, certain types of health conditions, such as diabetes and low blood pressure, necessitate eating before exercising, as a cardio workout on an empty stomach could cause other health problems. Medical conditions aside, some people are more prone to muscle loss than others, and some will burn fat more quickly or easily than others. Additionally, the altitude at which you work out makes a difference. People exercising at higher altitudes have less oxygen at their disposal, so running at a slower pace, which will lower your heart rate, will help you burn more fat. Many trainers say that to maximize fat burning, you should do your cardio workout at a level that allows you just enough breath to hold a conversation.

"Apple cider vinegar a day keeps the doctor away" doesn't exactly roll off the tongue, does it? Even still, many people claim that this product of fermented crushed apples yields a variety of health benefits including those that you mentioned. Usually taken in liquid, powder, or pill form before meals, it's most often used to aid digestion since the high acetic acid content helps break down food. In addition to this, it has also been used for centuries to treat fungal infections and sunburn. Although this may spark a domino effect on other aspects of health, there is no scientific proof that it has any effect on weight, blood pressure, or acne.
A common misconception about apple cider vinegar is that it curbs appetite and promotes fat burning, but physiologically, even though acetic acid intake may temporarily facilitate loss of water weight, it doesn't appear to affect fat. In fact, the high acidity of the vinegar may cause erosion of tooth enamel, throat irritation, and drug/supplement interactions (particularly with insulin and diuretics). It also acts as a blood thinner, so people who are on blood-thinning medications may want to reconsider its use.
Because the confirmed health benefits of apple cider vinegar are often a result of its high nutrient content (including iron, calcium, copper, and potassium), the choice between organic and non-organic is one to consider carefully. Non-organic apple cider vinegar has undergone pasteurization, the process of heating the liquid to a very high temperature to kill bacteria. As a result, the vinegar is much clearer and more attractive to consumers but in the process has lost the bulk of its nutrient content. Depending on what the consumer is aiming to gain from apple cider vinegar, this could affect the health benefits they experience. Then again, the potential bacteria content in organic (unpasteurized) apple cider vinegar could be problematic. Regardless of the nutritional supplement, a health care provider could be consulted before starting any alternative treatment.
Overall, if the reason for using apple cider vinegar is to lose weight, reduce blood pressure, or prevent acne, there are other treatments whose effects have been scientifically confirmed. In terms of weight loss, the key is to consume fewer calories than you burn on a daily basis. Routine physical exercise and a diet of fruits, vegetables, whole grains, and lean protein are your best bet. For more guidance on addressing these health concerns, see the Q&As below. You may also want to consider speaking with a health care provider or registered dietitian. Columbia students can make an appointment with Medical Services (Morningside campus) or the Student Health Service (CUMC).
In the end, an apple a day is more likely to keep the doctor away!
