Dear Dr. Mo: Is Zinc helpful in treating the common cold? Should I use it?
Dear reader: When we catch the infamous cold (acute upper respiratory tract infection), sometimes the symptoms may be severe enough that we reach out to anything that has even a hint of a promise of a quick cure.
The truth is, there’s no effective cure other than our own immune system and yet, many supplements are out on the market claiming to boost the immune response and help us fight off the virus.
Evidence is strong against any substantial effectiveness of any of these supplements.
Healthy diet and exercise remain the only sure fire ways to overcome the common cold – yes, even while you’re sick, if you can, you should moderately exercise (or at least stay active) and not rest for too long – this will speed up the recovery.
Zinc time and again emerges as one of the supplements suggested to help us fight the common cold but, does it work? Continue reading …
Legs could be windows into health – if they’re tired, you need a recharge
Dear Dr. Mo: My legs feel tired relatively often and I’d like to know if there is something I can do about it? Should I be worried?
Dear reader: The feeling of tiredness in legs is a relatively common complaint and the reasons for this feeling could be different. If the feeling is more than just tiredness and it extends into pain and cramps, swelling, numbness and other more severe symptoms, you should see your doctor immediately as these could signal a more serious underlying condition.
Use a healthy diet in your favour to get rid of tiredness in your legs and in some instances even pain (but like I said, for pain, always see your doctor first and discuss your options, including your diet).
Include foods that are rich in calcium, fiber, proteins and vitamin E in your diet as well as foods that will clean up your blood vessels and regulate your blood pressure. These ingredients will maintain your health and specifically improve the strength and fitness of your legs.
What exactly do I mean? Here are 5 important points that you can use in your diet to improve the health of your legs and reduce the feeling of tiredness:
Dear Dr. Mo: My blood pressure has recently been slightly elevated. Are there some ways to control it with a healthy diet before I turn to meds?
Dear reader: The so called ‘high normal’ blood pressure (130-139/85-89 mmHg) and even sometimes Stage I hypertension (140-159/90-99 mmHg) can actually be alleviated and managed with mostly life-style changes like salt restriction, proper hydration, quitting smoking, exercise and of course diet adjustments. I am not suggesting you shouldn’t take the meds prescribed by your doctor – do take them by all means as these are usually necessary to act as short-term blood pressure regulators. (In some cases, meds are constantly required). Continue reading …
Dear Dr. Mo: I’m a guy in my late 40s, not overweight and I work a lot. Is there something I can easily do to stay healthy and live longer?
Dear reader: Many things are important as we age, and this goes for both sexes, not just men: blood sugar levels, blood pressure, mobility and fitness, risks for cancer, heart and mental health.
For us men, I would say that the latter two are really important and that by maintaining them we surely improve all other parameters to help us live longer and better although women are no different in this regard. Continue reading …
for a weekly dose of healthy physical activity, which we believe will promote good health and a healthy weight, is that you cash in 150 minutes of moderate exercise (activity, which is aerobic) spread over a minimum of 5 days a week.
This formula can of course be played around with to match your needs, preferences and time. Continue reading …
Dear Dr. Mo: I want to know some basic facts about alcohol and what it does to me when I drink. Is there a safe amount that’s actually good for health?
Don’t drink and drive!
Dear reader: Sometimes you might hear from a doctor that moderate alcohol consumption is good for health.
The peril lies in the word “moderate” for it is arbitrary; it is not the same for everyone and one could easily slip from moderation to amounts that are not at all useful to health. We could certainly argue if alcohol is useful in any amount because while it may be beneficial to one part of the body, it is damaging to another.
We don’t really need alcohol as far as maintaining our health is concerned so if you’ve never drank, don’t start as risks outweigh potential benefits.
Dear Dr. Mo: Are there any health benefits I could possibly get by eating chocolate? I just love it so much.
Dear reader: What a sweet question (and I mean literally).
The answer is YES but let me make one clarification right from the start: when we talk about potential health benefits of chocolate, we always refer to dark chocolate, which has a high cocoa content.
Dark chocolate has health benefits
It is the Flavanols in cocoa beans that have antioxidant effects responsible for most of the benefits that come from dark chocolate consumption. Flavanols reduce cell damage implicated in heart disease and also help lower blood pressure and improve vascular function. In addition, some research has linked chocolate consumption to reduced risks of diabetes, stroke and heart attack. Eating a moderate amount of dark chocolate was associated with a lower risk of being hospitalized for heart failure.
Flavanols are thought to also reduce the levels of stress hormone Cortisol and its metabolic effects and they are being researched for their sun protecting abilities, doubling the time before which skin turns red in the sun, marking the beginning of a sun burn. Continue reading …
Dear Dr. Mo:How much water do I really need to stay hydrated and healthy?
Dear reader: This is the time of year where common colds are indeed common and when you will often hear that advice to drink lots of fluid, usually herbal teas or water. Of course, water is essential to your health but the needs for water vary from person to person and many factors may influence that, like for example your health condition, your daily activities, where you live, your age, metabolic rate etc.
Water means health!
Water is our main constituent – it makes up about 60% of our body mass. We need water to maintain normal functions: we throw out waste matter dissolved in water, water participates in digestion of food, it carries nutrients to cells, we use water to show emotions when we cry etc.
Water also helps to regulate body temperature through perspiration (sweating).
When water is insufficient we dehydrate. Dehydration is a state in which our cells don’t have enough water to function normally. Even a mild dehydration could cause fatigue because when tissues lose water, enzymes are slowing down their functions and energy production drops.
A simple way to see the link between health and water is to observe what happens when we age. As we age, the water content of our bodies is decreasing steadily and while a newborn is 80% water, in an adult this ratio is at 60% and it keeps on decreasing as years go by. Continue reading …
Dear Dr. Mo:What is the link between being overweight and developing Type 2 diabetes? Can diabetes be prevented or cured somehow?
Dear reader: First of all it is worth pointing out that diabetes is a chronic condition. For most types (except gestational type) this chronicity means that once it occurs, it stays for life – this is not a disease we can effectively cure with our present knowledge but we can quite successfully manage it.
Before I go into your question, let me first explain the diabetes landscape and basic mechanisms behind it as Type 2 is not the only game in town.
Diabetes occurs either when the pancreas no longer produces enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar.
The danger of diabetes lies in a condition called Hyperglycaemia – raised blood sugar level – which is a common result of uncontrolled/undiagnosed diabetes, which over time causes serious damage to the body, especially to blood vessels and nerves.
Food choices affect our health
Diabetes has its types and these differ in both the ways they start and the ways in which we manage them.
Type 1 Diabetes
This type had previously been known as insulin-dependent, juvenile or childhood-onset diabetes. Here, our pancreas gland becomes deficient in insulin production and there is simply no longer enough of it to properly regulate our blood sugar levels. Management requires daily administration of insulin and this type cannot be prevented with our current understanding as the cause is not known although we do think it is due to the self-inflicting damage to pancreas (process called “auto immune response”). Continue reading …
Dear Dr. Mo: I am looking into some weight loss programs and I am trying to work out my strategy to come back to my healthy weight. My work sometimes requires giving up on sleep and I tend to be too tired too often. Should I also consider better sleep as part of my weight loss strategy?
Dear reader: What an insightful question! Many of the dieting programs focus heavily on dietary habits and the types of foods we eat, when we eat them and how much. This is rightly so because to attain and maintain a healthy weight, we require a careful selection of healthful foods and a balanced way to eat them. We should also be mindful of our calorie total– don’t go below 1200 calories a day to avoid driving your body into starvation mode.
Sleep is a big part of your healthy weight
Dieting programs also focus on exercise, again rightly so because you need a way to burn through a few hundred calories a day in order to lose about 500 grams a week – which is the pace I’d recommend. If you cut out 500 calories a day, every day, you’ll be losing about 500 grams of weight a week.
What most dieting programs don’t talk about, and I think they should, is a major component of our health – sleep.
If we don’t sleep well and don’t get enough of it, our health suffers and it becomes increasingly difficult to curb the appetite and control our weight. Being overweight deteriorates our health in both the short and the long run.
Disrupted sleep patterns disrupt the circadian rhythm and increase sleep deprivation, which in turn increases the hunger hormone ghrelin.
There are two of these hormones that regulate our appetite and feelings of hunger and fullness – leptin and ghrelin – and both are directly affected by how much sleep time we give ourselves. Continue reading …
Dear Dr. Mo: Is sauna really healthy and should I go there when I have a flu?
Dear reader: When you are in most saunas, its dry heat, which can become as high as 85° C (in some saunas, even higher), can have some intense effects on the body.
Your skin temperature spikes to about 40° C within minutes. The average person will pour out a half a liter of sweat during a short stay in a sauna.
Saunas have been around for centuries – its relaxing and well-being effects on the body are well known
The heart rate jumps by 30% or more, allowing the heart to approximately double the amount of blood it pumps out each minute (its minute volume).
Stress hormones ACTH and Cortisol rise substantially while Adrenalin and Noradrenaline are reduced; other changes in hormonal balances happen as well.
These effects (vigorous sweating, increased heart rate and hormonal changes) are similar to those induced by a moderate exercise, which is why saunas could be so appealing.Circulation patterns change while in sauna and most of the extra blood flow is directed to the skin, which becomes reddish; the circulation actually diverts blood away from the internal organs.
Blood pressure in saunas is always unpredictable, rising in some people but falling in others, which might be a health risk for some people with blood pressure problems. Saunas generally should not be considered as a therapeutic approach to hyper or hypotension – visit your doctor first. Continue reading …
Dear Dr. Mo:What are some of the strategies to loose weight in a healthy way? I am not looking for instant results but something long term.
Dear reader: Losing weight and maintaining a healthy weight is no easy task these days. We live fast, eat fast and when weight is concerned – most people want to lose it fast, which is not a healthy way to go about it.
A few facts first:
Eat slowly and limit your portions
Our digestive system has several ways in which it talks to the brain to crank our appetite up or down. This conversation is a continuous process and it involves hormones made in the gut and by the cells that store fat, and it also involves nerve signals, especially the vagus nerve, which runs from the digestive system to the brain.
There’s a hormone called Ghrelin, which gets dispatched from the stomach into the blood to go to the brain and flick the hunger switch on – this is how we start to feel hungry. We respond by eating a meal and during this process our stomach and intestine produce hormones called Leptin and Cholesystokinin to tell the brain to start feeling full.
Vagus nerve is also involved as there are stretch receptors in the stomach, which register the stretch as the stomach fills with food and/or liquids. The stretch signals also tell the brain to feel full.
Dear Dr. Mo:How to cope with high blood pressure, walking or resting?
Dear reader: First of all, you have a high blood pressure or Hypertension, if you have a sustained elevation of resting systolic reading of at least 140 mm Hg (millimeters of mercury) or a diastolic reading of at least 90 mm Hg, or both.
Swimming could help to reduce high blood pressure
The top number in your blood pressure reading is the systolic pressure. It reflects the amount of pressure in your arteries when your heart pumps – it is generated by the heart as a pump and the larger its output, the higher the systolic pressure.
The bottom number is the diastolic pressure. It is the measure of the pressure in the arterial tree in between heartbeats, when the heart is relaxing and it depends on the total peripheral resistance to the blood going out of the arteries into the veins and back to the heart.
High blood pressure is a common condition in which the force the blood exerts against your artery walls is high enough to eventually cause health problems, such as heart disease. Heart has to work harder and harder as blood pressure rises above normal limits and over time, this weakens the heart. It also injures the arteries, which then become susceptible to plaque formation and atherosclerosis in them. At times, high blood pressure may rupture the artery leading to bleeding and strokes.
Blood pressure measurement is one of the most important measurements for any doctor to take in order to determine your health status. Many people have elevated blood pressure, which increases as we age or develop certain health conditions. The trouble is, that if left unchecked, our bodies quickly adapt to elevated values as we go about our daily lives unaware of a serious health problem slowly evolving inside of us – until a big symptom occurs – a heart attack, a stroke, a kidney failure, eye sight problem or internal bleeding.Undiagnosed and untreated elevated blood pressure is among the biggest and most serious threats to our health, both short and long term.
