Mad Carb Disease!

September 4th, 2007

Whether you’re trying to lose weight or just want to eat healthier, you may be confused by the news you’re hearing about carbohydrates. With so much attention focused on protein diets, there’s been a consumer backlash against carbohydrates. As a result, many people misunderstand the role that carbohydrates play in a healthy diet.

Carbohydrates aren’t all good or all bad. Some kinds promote health while others, when eaten often and in large quantities, may increase the risk for diabetes and coronary heart disease.

What are carbohydrates?

Carbohydrates come from a wide array of foods – bread, fruit, vegetables, rice, beans, milk, popcorn, potatoes, cookies, spaghetti, corn, and cherry pie. They also come in a variety of forms. The most common and abundant ones are sugars, fibers, and starches. The basic building blocks of all carbohydrates are sugar molecules.

The digestive system handles all carbohydrates in much the same way – it breaks them down (or tries to break them down) into single sugar molecules, since only these are small enough to absorb into the bloodstream. It also converts most digestible carbohydrates into glucose (also known as blood sugar), because cells are designed to use this as a universal energy source. This is why carbohydrates can make us feel energetic. Carbohydrates fuel our body. Your body stores glucose reserves in the muscles in the form of glycogen ready to be used when we exert ourselves.

Carbohydrates are the highest octane – the most desirable fuel source for your body’s energy requirements. If you don’t have an adequate source of carbohydrate your body may scavenge from dietary protein and fat to supply glucose. The problem is when you’ve depleted your stores of glycogen (stored glucose in muscle and lean tissue) your body turns to burning muscles or organs (lean muscle tissue) and dietary protein or fat to provide blood glucose to supply energy needs. When this happens, your basal metabolic rate drops because you have less lean muscle tissue burning calories and your body thinks its starving and cuts back on energy requirements.

So you should continue to eat carbohydrates discriminately selecting those which have the greatest health benefits.

The carbohydrates you consume should come from carbohydrate-rich foods that are close to the form that occurs in nature. The closer the carbohydrate food is as Mother Nature intended, the greater the density of other vital nutrients. If you are looking for health-enhancing sources of carbohydrates you should choose from:

Fruit: rich in fiber, vitamin A, vitamin C, folate, potassium and often vitamin E.

Vegetables: fiber, protein, vitamin A, vitamin C, often vitamin E, potassium and a wider variety of minerals than fruit.

Whole grains and grain foods: rich in fiber, protein, and some B vitamins and are very rich in minerals.

Legumes: an excellent source of protein, fiber folate, potassium, iron and several minerals.
Dairy foods: protein, vitamin D, calcium, phosphorus, potassium, riboflavin, and vitamin B12.

You can also source carbohydrates from processed foods such as soda pop or soft drinks, snacks such as cookies and chips, and alcohol. These generally are considered to be a poor food choice and should be consumed rarely. The carbohydrate source (sugar and flour) in these food choices has been highly refined processed. A diet rich in refined carbohydrates and processed foods has been associated with heart disease and onset of type 2 diabetes.

Why are these sources of carbohydrates to be avoided?

1.They are calorie dense and contribute a large number of calories in a small amount of food. For example a 7oz bag of potato chips or corn chips have approximately 1000 calories. Most women on a weight management program will be aiming for 1200 daily calorific intake. So, this is what we mean by calorie dense and nutritionally scarce.

2.They offer little appetite-holding power because they have no fiber or protein. As a result you end up searching for food again soon after your first serve.

3. They contribute nothing to your nutritional profile except calories. This means you have fewer calories left for foods that your body requires for good health.

Whenever possible, replace highly processed grains, cereals, and sugars with minimally processed whole-grain products and ensure you have at least five serves of fruit and vegetables daily.

Rather than cut out carbs completely for a very short-term gain (usually weight loss), there are greater long-term health benefits in learning how to distinguish good carbs over bad carbs and incorporating healthy carbohydrates into your weight loss program.

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.
