Heart Rate Monitors

Heart rate monitors used to be exclusively operated by physicians and nurses alone but that was soon rectified with today’s multi-tasking generation. Every person seemed to want to know about everything that was related to them and that of course included monitoring their own heartbeats.

What is a Heart Monitor
Also known as a cardiac monitor, a heart monitor is a piece of electronic equipment that can be used to track or observe heart functions continuously. It allows people to place a numerical value on their healthiness based on their heart rate and have a target heart rate to work for. The more complex versions of the heart monitor allow physicians to see any signs of deterioration or improvement and make the necessary adjustments immediately.

Types of Heart Monitors
Today, heart monitors are produced by the millions and designed to cater specific types of individuals. Some heart monitors are primarily designed for weight loss programs while others are meant for the use of athletes or fitness programs. Some are wireless or come as a built-in feature of exercise equipment like a treadmill or an exercise bike. It can be strapped to your wrist or of considerable size. It may or may not emit any electromagnetic waves, depending on its purpose. A fetal heart monitor, for instance, must not produce any waves at all as this may affect the health of the baby.

Factors on Selecting the Best Heart Monitor for You

ECG-Accurate Monitors with Chest Straps – Heart monitors that come with chest straps are more often not the most accurate of heart monitors. The chest strap is strapped around your chest, a few centimeters below your breast. It contains a device that’s able to detect electrical activity of your heart and transmit it to the brain of the machine – just like an ECG. The results are shown on the display monitor, which most of the times is attached to your wrist like a watch. Others however prefer results to be transmitted through audio messages via earphones.

Upon choosing heart monitors with chest straps, you need to remember to keep the strap constantly connected to your body lest you want the heart monitor to produce inaccurate readings.

Lastly, the only alternative against buying heart monitors with chest straps are the ones that rely on pulses on your fingertips. These however do not provide readings as accurate as those with chest straps.

Heart Monitor Features – Basic and lower end models tend to display only your heart rate and maybe the elapsed exercise time as well. This of course does not provide sufficient information if you want to know exactly how much you need to improve before you can be qualified as a completely healthy individual. Higher end models will naturally offer a wider range of features – for a price. Examples of such features are – but not limited to – heart rate zone alarms, timers and number of calories burned. It may also allow users to set pre-programmed workouts along with a targeted heart rate.

Ease of Use – Lastly, you must purchase a heart rate monitor that you will have no problems of using. What good would a high end heart monitor do if it takes you an hour to operate it? Are the numbers and words appearing in the heart rate monitor readable? Can it be used in no-light situations? Are buttons well-labeled and ergonomically positioned?

To Buy or Not to Buy a Heart Monitor
Heart monitors can be especially costly, more so if you are intent on purchasing higher-end models. If you have a limited budget, you should ask yourself whether or not you truly need to buy a heart monitor. You can of course purchase one of the lower-end models but low quality heart monitors can lead to inaccurate results and that sort of defeats the purpose of buying one.

If you are intent on purchasing a heart monitor, you need to ask yourself another question: do you need to make a solo purchase or is it alright with you to use the heart monitor that comes as a built-in feature of a treadmill? Lastly, you should remember as well that you can always pay your doctor regular visits and have him monitor your heart rate for you.

How to Read Food Labels

You cannot measure every morsel that passes your lips, but it is a good idea to measure most foods and beverages until you get a feel for portion sizes.

It is a supersized world out there, and most people are surprised to find that their idea of a single serving is actually two or three.

If you are into bells and whistles, there are food scales that are preprogrammed with nutritional information, as well as scales that will keep a running total of your daily food and nutrient intake for you. The only tools you really need, however, are a simple and inexpensive gram scale, dry and liquid measuring cups, and idea on reading food labels.

Among all of the mentioned tools, reading food labels seem to be the most effective way of determining the right kind of food to be bought in the supermarket. It lets you make sensible food selections. Through the “Nutrition Facts” section in a particular item in the grocery, you can identify the amount of serving sizes provided in that product.

With food labels, you can clearly understand the amount and kinds of nutrients that are provided in the item. Usually, it contains the information on saturated fat, sodium, total fat, fiber, and cholesterol amount “per serving.”

However, understanding and reading these food labels can be very perplexing. A typical consumer would definitely ask what those numbers mean and how it will affect her diet intake if ever she will religiously follow the serving guide as stipulated on the food label.

To further have a clear and more comprehensive understanding of the items stated in the food label, here is a list of things that you need to know:

1. Serving size

This is the primary item you will see in a food label.

The amount of servings stated in the food label refers to the quantity of food people usually consume. However, this does not necessarily mean that it reflects your very own amount of food intake.

Moreover, serving size determines the amount of nutrients that enters the body. This means that if you will follow strictly what the serving size is, you will obtain the same amount of nutrients according to the serving size that was given in the label.

For instance, if the serving size says one serving size is equal to 54 grams, that would mean you have to measure 54 grams and eat that and you have just eaten one serving. So to speak, the amount of nutrients stated in the food label is the same amount that has entered your body considering the fact that you have just eaten 54 grams.

However, if you have eaten everything, and the food label says that each pack is equivalent to 4 servings, you have to calculate the amount of nutrients that have entered your body. This means that if the food label says 250 calories per serving that means you have to multiply it to four to get the total amount of calories you have taken.

2. Nutrients

This refers to the list of available nutrients in a particular item. It is also where the nutritional claims of the product based on the recommended daily dietary allowance are stated. Usually, the nutritional amounts are based on both the 2,500-calorie diets and the 2,000 recommended dietary allowances.

In order to understand the numeric value of each item, you should know that the “% daily value” that the food label indicates is actually based on how a particular food corresponds to the recommended daily dietary allowance for a 2,000 calorie.

If in the event that you have purchased an item that has a dietary allowance different from the 2,000-calorie diet, you just have to divide the stipulated amount by 2,000 and you will be able to identify the “%daily value” for the nutrients.

3. Ingredients

This refers to the list of the ingredients that were used to manufacture the product. The listing is usually arranged from the main ingredients that have the greater amount by weight up to the smallest quantity. This simply means that the actual quantity of the food includes the biggest quantity of the main ingredient or the first item and the minimum amount of the very last ingredient.

4. Label claim

This refers to the kinds of nutritional claims of a particular food item. For instance, if an item says it is sodium-free, it has less than 5 milligrams per serving or a low fat item actually contains 3 grams of fat or less.

Indeed, reading food labels can be very tedious and confusing. Nevertheless, once you get the hang of it, it would be easier for you to watch your diet because you can already control the amount of food that you take.

Soy Beans are Very Versatile
Soy beans are very versatile. Various cuisines, especially Asian ones recognize the value of the humble soy bean. A variety of naturally yummy delicacies are all soy based: tofu, soy pudding, Soya milk, and meat substitutes – not to mention condiments such as soy sauce, and hoi sin sauce.

To counter the problem of world hunger, the growing of soybeans has been suggested. Not only are soybeans easy to grow and harvest, they will grow pretty much anywhere and produces much in a little time.

Soy is low in fat and can be used to substitute most protein sources. When cooking, you may use soy substitutes instead of flour for a low fat alternative. This makes it a great protein source for those that are looking to lose weight without compromising their protein requirements.

Bodybuilders are considering how this can make their jobs a lot easier. Without the fat and with all the protein goodness – easily digestible at that – bodybuilding has just received a great blessing of a food.

Isoflavones are powerful antioxidants and prevent the effects of free radicals in the body. They prevent many of the signs of aging and have been known to help prevent cancer. This alone makes soy a miracle protein source in its own right.

Isoflavones, along with vitamins A,C, and E are among the front liners in the fight against such disease – they also counter the effects of pollution, and stress.
