Fats And Carbs – Good Or Evil?

July 26th, 2007

Fats and carbohydrates are two building blocks of a healthy diet, but many people do not understand their role in proper nutrition. While the daily intake of fats and oils should be limited, these elements are still a vital part of the diet. The key is to make smart choices when it comes to fats and oils. That means substituting saturated fats with unsaturated fats, and using healthier, lighter oils in cooking.

Let’s look at the role fats and oils play in the diet. Fats are necessary for supplying energy to the body. In addition, fats supply essential fatty acids and act as carriers for fat soluble vitamins like vitamin A, vitamin D, vitamin E, vitamin K and the carotenoids. In addition, fats have an important role to play as building blocks for various tissues and membranes, and they also play a key role in regulating numerous bodily functions.

Dietary fat is available from a variety of plant and animal sources, and most diets do contain adequate amounts of fat. Most nutrition experts recommend keeping the intake of fat to less than 20% of calories, but studies have shown that severely limiting fat intake can be dangerous. Extreme low fat diets should only be undertaking with a doctor’s approval and oversight.

The type and amount of fat in the diet makes all the difference. A diet high in saturated fats, trans fats and cholesterol has been associated with a variety of ills, including heart disease, stroke and other associated diseases. In addition, many long term chronic problems, such as obesity, are associated with high levels of dietary fats.

The greatest risk of complications from excessive fat intake appears to lie with saturated fats and trans fats (fats that are solid at room temperature). One of the best ways to keep levels of saturated fat low is to limit the amount of animal fats that are consumed. These animal based fats include meats like bacon and sausage, as well as butter and ice cream. Dietary cholesterol can be limited by watching the consumption of eggs, organ meats and other foods high in cholesterol.

Food labels do make the complicated process of choosing the right fats somewhat easier. For instance, trans fats will be listed on the ingredient list of foods that contain them. In general, trans fats are found mainly in processed foods.

Some fats, such as polyunsaturated fats and monounsaturated fats, are better choices for healthy eating. Examples of these fats include canola oil and olive oil. Cooking with these lighter oils can be a big step toward a healthier diet. Polyunsaturated and monounsaturated fats are liquid at room temperature, and they have been found to have heart protecting qualities.

Many types of fish have also been found to be sources of good fat. Fish are excellent sources of omega-3 fatty acids. These omega-3′s have been found to promote good health, and they may even lower cholesterol levels.

Carbohydrates are an important part of a healthy diet as well, and carbs are necessary for providing energy and many essential nutrients. Carbohydrates are found in fruits and vegetables, in grains and in milk and dairy products. It is important to choose carbohydrates carefully, however, since not all are equally healthy.

When choosing breads and cereal, for instance, try to select those made with whole grains, while avoiding the more highly refined varieties. It is also important to limit the intake of sugars, such as soda, candy and highly processed baked goods. Consuming large amounts of such high calorie, low nutrient foods, can make it very difficult to stay on a healthy diet without gaining weight.

Most Americans tend to have too much of certain elements in their diet. Sugar is one such element and salt is the other. While a basic level of sodium in the form of salt is important to proper nutrition, most people consume too much salt in their daily diet. Excess salt consumption can lead to water retention, high blood pressure and other complications. Choosing low sodium foods, and limiting the use of the salt shaker, can go a long way toward cutting levels of excess salt in the diet. other complications. Choosing low sodium foods, and limiting the use of the salt shaker, can go a long way toward cutting levels of excess salt in the diet.

High Protein Diet – Opposite to a Low Carb Diet?

July 22nd, 2007

High protein diets are usually associated with low carbohydrates, even though people who have high protein requirements, like professional body builders, are not advised to go on a low carb diet. Protein is one of the most important nutrients necessary for health. The body uses it to build muscle, replenish cells, keep the blood in optimum condition, and basically to keep the body operating smoothly. If done properly, a high protein diet will keep you strong, healthy, and happy.

A high protein diet can provoke weight loss, as several studies have indicated. Proteins are composed of amino acids, and science has shown that if your amino acids are deficient, you are prone to a number of health problems, including obesity. If you concentrate on protein-rich foods and minimize your intake of refined food that have a high carbohydrate and sugar content, after a while, your body will enter into a state called ketosis. Instead of burning carbohydrates as fuel, the body will turn to fat as its primary source of energy. Simply put, the less carbs you have in your body to burn, the more fat your body will use to give you the energy you need to live from day to day.

In addition, it has been proven that eating protein-rich foods leaves you feeling full longer and you will find that you are much less inclined to snack or go on an eating binge. This is because your blood sugar and insulin levels are kept within the normal range you’ll be keeping undue hunger at arm’s length.

Going on a high protein diet does not mean, however, that you are free to gorge on any and every type of protein. You would do well to avoid fried foods dripping in oil or margarine-smothered products. The reason for this is because these foods contain so-called trans-fats and other bad oils and fats that can lead to clogged arteries and heart disease. However, there is a wealth of other types of fatty, protein rich foods that are quite nutritious.

As is common knowledge, meat is an excellent source of protein. Pork and beef contain ample amounts of this nutrient. But if you are concerned about fat, you should limit your portions of dishes containing meat. On the other hand, there is no need to worry about oils and fats if you eat fish and other seafood. Aside from being rich in protein, they contain essential fatty acids that improve your blood cholesterol levels and help prevent ailments like stroke and coronary artery disease. So you need not have any qualms about indulging your appetite at a seafood buffet – most of them can do no harm, only good.

Many plant products also have a rich amount of protein in them. Soy-based produce like tofu and soy milk are suitable for those trying to lose weight on a high protein regimen. So are pulses and beans. Not only are they protein-rich, they are usually low-fat and low-carbohydrate as well.

There have been concerns that a diet rich in protein can have adverse health effects. Some health experts claim that too much protein can deplete the body’s calcium supply and lead to diseases like osteoporosis. Another concern is that the kidneys are forced to deal with more byproducts, thus lessening their efficiency. And there are indications that too much protein increases uric acid levels, which can lead to gout or kidney stones. However, the jury is still out on whether protein is the major culprit in these conditions. More, longer-term research is needed to determine this although there are also many studies that are being conducted to explore these problems, their extent, and their possible resolutions.

A high protein diet may not be for everyone, but for a vast number of people, it not only helps them in their weight loss efforts, it keeps them healthy, too! If you are considering going on this diet, always remember your limits and stick to the rules. It’s possible to modify it a little bit in various ways (such as reducing the intake of saturated fats) to suit your personal taste, but don’t deviate from the “main course.” Choose your protein sources wisely, don’t forget to exercise, don’t be a glutton (it’s one of the seven deadly sins, after all) and just watch the pounds melt away.

Fats And Carbohydrates – Their Place In A Healthy Diet

June 28th, 2007

Lately it would seem that fats and carbohydrates have both gotten a bad rap. First it was fat that was the culprit in all dietary ills, and low fat diets were all the rage. Then the two switched places, with carbohydrates being the bad guys and fat reigning supreme.

As with most extremes, the truth lies somewhere in the middle. There is no such thing as a bad food, only bad dietary choices. While some foods are naturally better for you than others, there is no reason that all foods cannot be enjoyed in moderation. After all, the most successful diet is not one that you can follow for a day, a week or even a year. On the contrary, the only successful diet and nutrition program is one that you will be able to follow for a lifetime.

Both fats and carbohydrates play an important role in nutrition, and both are important to a healthy diet. It would be impossible and unwise to eliminate all fat from the diet, since fat is important for the production of energy, and for carrying valuable fat soluble vitamins like vitamin D, vitamin E and vitamin K, throughout the body. In addition, fat plays a vital role in regulating various bodily functions.

Even though some fat is essential to a healthy body, too much fat can be harmful. Excessive levels of dietary fats have been implicated in heart disease, stroke, high cholesterol levels and even some cancers. Most nutritionists recommend limiting daily fat intake to less than 20% of calories, although taking that level lower than 10% is not recommended.

Of course not all fats are created equal, and some fats are more harmful than others. Saturated fats and trans fats are generally understood to be more harmful in the diet than polyunsaturated and monounsaturated fats. These lighter fats, like canola oil and olive oil, should form the basis of cooking a healthier diet.

Keeping saturated fats and trans fats to a minimum is important to a healthy diet. Trans fats, which are solid at room temperature, are most often found in highly processed foods like cookies, cakes and other baked goods. In addition, trans fats are often found in fried foods and in salty snacks like potato chips. While these foods are fine in moderation, it is best to avoid large quantities of such snacks.

One additional word here about good fats – yes there are such things, and one of the most powerful of these are the so called omega-3 fatty acids. These fats are most often found in fish, and they have shown great promise in preventing and even reversing heart disease and high cholesterol levels.

When limiting your daily intake of fat and cholesterol, it is good to have an understanding of nutritional labels. These government mandated labels can be a huge help to those who take the time to read and understand them. Not only do nutritional labels provide valuable information on calories, fat content and sodium, but they provide valuable information about the most important vitamins and minerals as well.

Like fats, carbohydrates are found in a variety of different foods, some healthier than other. For instance, both Twinkies and whole wheat bread are sources of carbohydrates, but while one can form the basis of a healthy diet, the other is best used as an occasional snack.

In addition to cereals and breads, carbohydrates are also present in fruits and vegetables and in milk and other dairy products. Carbohydrates and fats are both important to a healthy, varied diet.

As with many products, less is often more when it comes to choosing foods rich in carbohydrates. For instance, less refined whole grain bread is generally more nutritious than white bread which has gone through a greater amount of refining. That is because the refining process tends to reduce nutrient content over time.

Of course, there are some elements in the diet that should be limited. Two of these elements are sugar and salt. Most Americans consume too much salt and sugar, and this has led to epidemics of obesity, diabetes, heart disease and other ills. Limiting sugar and salt, while choosing good fats and unrefined carbohydrates, is a great way to maximize the nutritional value of the foods you eat.

What You Should Know About Low Carb Diets!

May 11th, 2007

What is a Low Carb Diet? You’ll do away with bad carbs and bad fats, and start eating good fats and good carbs. What you need to understand is that you are not really on a diet, but changing the way you eat. Eating the wrong foods consistently throws your body out of balance. Most of us tend to overdue it eating processed carbs. What do I mean by processed carbs? Basically, there are two kinds of carbohydrates, simple and complex. Some refer to them as bad and good carbs, fast and slow digestion carbs and others. Here are some basic explanations:

SIMPLE CARBS – Foods with simple or refined carbohydrates most often have a low nutrient content and a high-glycemic index. They are metabolized quickly (quick to digest). They enter the bloodstream and rapidly elevate blood sugar levels, then fall dramatically within a short span of time. In order to keep the body running healthy and stable, it is recommended that these type foods be limited. Examples of these simple or overprocessed carbs are white bread, potatoes, and sugary treats like cookies, candy, cupcakes and cakes, and beverages like cola products.

COMPLEX CARBS – Foods with complex carbohydrates contain many nutrients and have a low- to moderate-glycemic index. Higher fiber content in these foods means slower digestion, which is healthier for the body (including reducing mood swings and food cravings). And these foods are considered good choices by health advisors. Examples of these complex carbs are whole grains, most fruits and vegetables. Legumes, plants of the pea or bean family, are also in this category.

WHICH IS BEST?? Studies show that low-carb diets can help with weight loss; which means that the carbs need to be of the complex, low-glycemic type. The key is eating whole, real, unprocessed food found as close to nature as possible.

WHY DOES YOUR BODY NEED CARBOHYDRATES ANYWAY? Carbohydrates cause your body to produce a hormone called Insulin. Insulin is responsible for the movement of glucose (sugar) from the food you eat into the cells of your body to be used for energy. Excess glucose (that is not burned as energy) is then stored as body fat.

Years of consuming too many carbohydrates can lead to a sensitivity of the cells to Insulin. This can result in the body having to make more (and more) Insulin to get the same job done. Over time over-production of Insulin can lead to high cholesterol, heart disease, obesity and type II diabetes and more. A side effect of Insulin over-production is that it actually causes more fat to be deposited.

EATING LOW CARBS WORKS WITH YOUR BODY.

All the food you consume provides energy for your body. Your body burns fuel in this order: carbohydrates / fat / protein. So, by limiting the carbohydrates you eat, it is perfectly natural for your body to burn fat next. Your body will go inward and start burning your own body fat for fuel. Because of this store of body fat, you wont feel hungry and you will maintain a more even blood sugar level throughout the day.

One important thing to note here is … it is not eating too much fat that makes you overweight – it is eating far more carbohydrates than your body needs to use for energy.

It is important, however, that any and all dietary planning should be made under the guidance of your own medical practitioners. Also, drinking 8 glasses of water a day and consistent exercise is vital to your body’s health. This content only presents overviews of low-carb research for informative purposes and does not replace medical advice from a professional physician.

Whither Low-Carb?

May 3rd, 2007

Fads fade for a reason. Like pet rocks, low-carb diets will disappear because they just don’t do anything worthwhile. The drop-out rate is high – about 50 percent because the diets are boring and are unpalatable to most people. More than 90 percent of dieters return to their previous weight within 5 years, most of them even sooner. Minor side effects such as headache, fuzzy thinking, irritability, halitosis and constipation are almost universal among Atkins adherents. Severe side effects are, fortunately, rare.

Physicians are concerned that long-term adherence to a high-fat, high-protein, low-carbohydrate diet may lead to kidney stones, osteoporosis and heart abnormalities. Kidney stones and disturbances of heart rhythm are well-documented complications of the decades-old ketogenic diet (high fat, low protein, low carbohydrate) that paediatricians have used to lower the seizure frequency in children with neurological disorders.

A reputable journal reported in May 2004 that low-carb diets helped people lose weight without causing adverse effects on cholesterol levels. There was joy among food manufacturers, who had already rushed to market low-carb products that covered the spectrum from beer to bonbons. Lost in all this was the cool scientific observation that overweight persons experienced only a moderate weight loss, and that severely overweight individuals lost, on average, only one pound per month during the study year. The cholesterol profiles did, indeed favor the low-carb dieters, but those levels remained high because thats where they started out. Finally, few journalists revealed that the Atkins Foundation funded one of these studies

Those who can successfully navigate the inconvenience and side effects of the low-carb diet and then maintain a significant loss of fat will gain much benefit. The early weight loss, however, is mostly water. Much of the later weight loss consists of lean body mass, mostly muscle. Long-term success depends not only on careful attention to diet, but also to regular exercise. Those who do not incorporate an exercise routine into their life are destined to gain all the weight back, and then some.

In what direction is the low-carb phenomenon going? First, proponents are already backing away from saturated fat. The South Beach diet recognizes that polyunsaturated (from fish) and monounsaturated (from olive oil) fats are not only acceptable, they are essential to good health. Second, the distinction between refined carbohydrates (white flour, sugar) and whole grains is one that needs to be widely disseminated. Third, the low-fat establishment cannot and must not ignore the overwhelming benefits of fruits and vegetables in the prevention of cancer and heart disease.

The low-carb craze has probably reached its peak, but remnants will persist for a generation or more, and permutations of it will rise episodically like phoenixes among those who are looking for effortless weight loss. Like the phoenix, that is a myth.

Santa Goes Low Carb!

April 21st, 2007

North Pole- The word is out! Due to an “unpublished dilemma” last Christmas Eve Santa has gone Low Carb!

Sources reveal that Santa was stuck in a chimney somewhere in California for over an hour last Christmas Eve – how embarrassing! The incident certainly wreaked havoc with his jolly schedule for the most important night of the year. In the aftermath, it caused Santa to really stop and think.

After careful consideration – Santa and Mrs. Claus decided they could not risk a repeat of the incident, but more importantly the risk factors associated with Santa’s health – oh my! Right after the holidays, Santa visited his primary care physician for a complete physical. A “new lifestyle” was decided upon – It’s the “Low Carb Lifestyle” for Santa!

Santa has Changed His Mind – Changed His Heart – and is Losing Weight for Life! Will this make Santa “less jolly”? Absolutely not! Fat is not what makes Santa jolly! His weight goals are not to be a skinny “Twiggy Santa” but rather a “healthy weight Santa” with less inches (for some VERY obvious reasons). The keyword here though for Santa is: HEALTH!

Our sources tell us that Santa has more energy than ever, his creativity and staying power seem to be at an all time high! He has hired more elves this season just to keep up with him! The jolly fellow is even less stressed this season.

The absence of stress seems to be relative to the fact that his chances of losing his jolly lifestyle to diabetes, heart disease and obesity have been considerably reduced by his new choice of a healthy eating lifestyle! Santa has serious work to do and HEALTH has become his priority!

In fact, our elf resource reported that we are going to see a big shift in “stocking stuffers” this Christmas. Huge orders are being received and warehoused at the North Pole for “sugar free” candies and low carb treats! Santa’s sleigh is going to look like a “sugar free zone” this year!

With Christmas quickly approaching, as Santa’s inches have dropped away, the “sewing elves” are working round the clock in altering Santa’s RED wardrobe!

So this Christmas watch for an even “more jolly” Santa and just a “little less” of him but a much healthier and happier Santa ’cause he’s gone Low Carb!

And…”Laying his finger aside of his nose and giving a nod, up the chimney he [easily] rose!

He sprang to his sleigh, to his team gave a whistle, And away they all flew like the down of a thistle. But I heard him exclaim, ere he drove out of sight,”HAPPY [LOW CARB] CHRISTMAS TO ALL, AND TO ALL A GOOD-NIGHT!”

Low GI Diet or Low Carb Diet – Which One Is Best?

April 9th, 2007

These days, most everyone has heard of low carb diets such as the South Beach and Atkins diet but the GI or glycemic index diet is a fairly new name on the diet scene. While low carb diets restrict the quantity of carbohydrates, the GI diet focuses on the quality of carbohydrates. It works by promoting the consumption of foods that are low on the glycemic index, foods which will have a gently effect on your blood sugar levels and keep you full longer.

A typical low carb diet, has a restrictive phase in the beginning where your carbohydrate intake is severely limited. You can eat all the meat you want and fats are also unlimited, although the South Beach Diet does encourage you to stick to low fat meats and healthy fats. As the diet progresses, you can gradually add in more carbohydrates, typically those with a low glycemic index are also those that are lower in carbs.
Although a low GI diet might be new to you, it has actually been around since the 1970s and is used in many European countries to help manage diabetes. Recently, however, this way of eating has gotten a lot of attention as a healthy way to control weight. This diet focuses on carbohydrates good carbs have a low glycemic index and you should eat plenty of them (incidentally, these are also the foods that we know to be good for us like fruits, vegetables and whole grains). Bad carbs have a high glycemic index and should be eaten in moderation and mixed with the low glycemic index carbs to lower the overall GI of a meal. Since this diet focuses only on carbs it is very easy for vegetarians to adopt this way of eating.

In comparison, a low carb diet can be limiting in fruits and vegetables which are high in vitamins, minerals and enzymes as well as fiber. Many people associate low carb diets with a license to eat as much saturated fat as you want, but that choice is up to the individual so we really cant fault the diet for this misconception. A low GI diet is full of fruits, vegetables, fiber and low in fat but emphasis the good fats found in nuts. It encourages eating lean meats in moderation.

While we all know that meats and fats are no carb and green leafy vegetables are low carb, some may not be aware of what foods have a low glycemic index. Most vegetables (except potatoes, beets, pumpkin) have a very low GI. Some fruits that have a low GI include citrus fruits, apples, plums and peaches while most other fruits have a medium GI value. Oatmeal, most pasta and whole wheat bread also have a low GI.

So which diet is best?

Where many people in the health and nutrition profession consider a low carb diet to be unhealthy, most everyone would consider a GI diet to be very healthy. Studies have shown that eating lots of fruits and vegetables can help to bolster your immune system thus allowing you to fight disease and eating high fat meats may adversely affect your health and help contribute to heart disease. That being said, it has also been shown that being overweight is a major health risk for many diseases so the best diet is probably one that works for you! Some folks might respond better to a low carb, others to a low GI. Either way, it makes sense to make healthy food choices, limit food intake and exercise for your good health.

Low Carb Diets – How Much Protein Do You Need

March 16th, 2007

What is protein?

Millions of different proteins occur in nature. Protein is made of chains of amino acids held together by peptide bonds. There are about 20 amino acids that can be bound together in various combinations to make the millions of different proteins. There are two groups of amino acids: non-essential amino acids, which are made by your body and essential amino acids, which have to come from your food.

Why does my body need protein?

Protein is an important part of muscle fibre, cell walls, skin, nails and hair. You are losing protein all the time as you shed dead skin cells, nails and hair and it has to be replaced. At times your body needs more protein, like when you’re growing, when you’re pregnant or breast-feeding, or when wounds are healing. Protein is a source of energy for your body and the amino acids are used to make things like adrenaline and antibodies to fight disease.

How does my body digest the protein I eat?

When you eat protein, your body’s digestive system breaks it down into its component amino acids. These are absorbed into your bloodstream through the walls of your small intestine and your liver. Your body puts the amino acids together in whatever combinations it needs, e.g. to make hair protein or new skin cells. Proteins include nitrogen molecules and one of the byproducts of digesting proteins is ammonia. This is converted into urea which is filtered by the kidneys and passed as urine.

How much protein does my body need?

Health authorities in the U.S.A., Canada and Australia recommend a daily intake of 0.75 – 0.8 grams of protein per kilogram of bodyweight. If you weigh 80 kilograms, that’s 60 grams of protein a day. High protein (or low carbohydrate) diets will recommend more.

Can my body store protein?

No. You need to eat the protein your body needs every day. Any excess protein is converted into urea and passed as urine.

Are all proteins the same?

Different proteins are made up of various combinations and amounts of amino acids. Proteins from animals, fish, poultry, soy and Amaranth contain all of the essential amino acids and are they are easily digestible. Proteins from plants and grains do not usually have all of the essential amino acids and you need to eat a selection of them to get all the amino acids you need.

What if I don’t eat enough protein?

Most people eat more than enough protein. If you don’t eat any animal products, you should eat a wide variety of plant and cereal foods. Some symptoms of protein deficiency are: poor growth, weight loss, muscle wasting, iron deficiency, swollen feet and ankles.

Is it dangerous to eat too much protein?

There are risks associated with following a high protein diet for a long time. Your kidneys have to collect and filter more toxic byproducts. This may affect the function of your kidneys, particularly if you have diabetes. It is possible for calcium to be lost from your body. If animal products are your main source of protein, you should avoid those that are high in saturated fats and cholesterol because they will increase the risk of a number of diseases including heart disease.

The Effect Of A Low Carb Diet On Your Insulin Level

March 8th, 2007

The underlying principles of low carb diets are based on the role of insulin in our body. There are three basic units the body uses for energy: Fats, Proteins, and Carbohydrates.

All three can be converted to blood glucose. However, while fats and proteins are converted slowly, carbohydrates are converted quickly causing quick spikes in the bodys blood sugar levels. These spikes in blood sugar levels cause the pancreas to create and release insulin until the blood sugar level returns to normal.

Meanwhile, insulin, a hormone produced in the pancreas that lowers our bloods glucose levels is released into the blood as soon as the body detects that blood sugar levels have risen above its optimal level.

Insulin is a very efficient hormone that runs the bodys fuel storage systems. If there is excess sugar or fat in the blood insulin will signal the body to store it in the bodys fat cells. Insulin also tells these cells not to release their stored fat, making that fat unavailable for use by the body as energy.

Since this stored fat cannot be released for use as energy, insulin very effectively prevents weight loss. The higher the bodys insulin levels, the more effectively it prevents fat cells from releasing their stores, and the harder it becomes to lose weight. According to many authorities, over the long term, high insulin levels can lead to insulin resistance and cause serious health problems like obesity, accelerated aging, increased food allergies and intolerances, overworked immune system, heart disease, diabetes, and even cancer.

Carbohydrates, especially simple carbs like sugar and starch, are quickly turned into sucrose by the body entering the blood stream quicker thereby causing the release of large amounts of insulin. The fewer carbs are eaten, the less insulin is produced by the body, and the fewer calories are stored as fat. Less fat storage equals less weight gain and fewer carbs eaten equals less insulin in the blood and the body using its fat stores for fuel.

The premise behind every low-carb diet plan is that a body that produces less insulin burns more fat than a body that produces lots of insulin. Some plans encourage a period of extremely low carbohydrate intake so that the body will enter a state of ketosis and more quickly burn fat stores.

These are usually called induction periods. The length of extreme carb control varies from seven days to however long it takes you to reach your ideal weight. After this period of extremely low carb dieting, maintenance levels of carb consumption are followed to prevent weight gain. The amount of carb you can safely eat will depend on your unique body system. And you will probably have to experiment to find out what level of carb intake is best for you.

No matter what your carb intake, it will be lower than the norm and you will still eliminate white flour and white flour products and certain other sugary and starchy foods. This is why these diet plans are known as low-carb lifestyles.

Low-carb success requires that you be willing to give up simple carbs for the long-term.
