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.

Can A Low Carb Diet Help You Avoid Trans Fats?

September 29th, 2006

Unless youve been living under a rock, you’re probably aware that trans fats are thought to contribute to heart disease, weight gain, and other health problems. These transformed fatty acids are commonly referred to as Trans Fatty Acids or TFAs and are present in most of the packaged foods found in the grocery store and your pantry!

Trans fats are produced by hydrogenation – the process of heating an oil and passing hydrogen through it. This process turns liquid oils into solid (margarine, Crisco) and extends the shelf life of most processed foods. The high temperatures used to heat the oils also destroy the essential fatty acids and transforms them into trans fats (short for transformed fatty acid). These fats compete with essential fatty acids for absorption in the body and are thought to contribute to coronary heart disease by raising LDL cholesterol levels (bad cholesterol), while lowering the HDL levels( good cholesterol). They also increase platelet aggregation, which in turn increases the chance of blood clotting, strokes and heart attacks. And if that isn’t bad enough, they also create free radicals that have been linked to cancer.

If you are on a low carb diet, chances are that you don’t eat very many processed or fried foods so you wont be consuming much food with trans fats. If you are sticking to mostly low fat meats and vegetables youre probably in pretty good shape as far as trans fats ingestion goes. Margarine is high in trans fats, but there are several brands out there that have no trans fats so if you are eating a lot of margarine, you may want to look into the brand you are buying. Mos of the foods high in trans fatty acids like chips, doughnuts, muffins, cakes, candy, soups, breads, margarine, cheese spreads, and cookies are no-nos on a low carb eating plan so cutting them out of your diet has the added health benefit of reducing your intake of these fats.

How do you know if a food has them? Well, the food industry doesn’t make it easy, they rarely put their content on the labels so you will need to figure it out by reading the ingredients. When buying packaged foods beware of the word hydrogenated or partially hydrogenated in the list of ingredients. These foods will contain trans fatty acids. If you are leading a low carb lifestyle you probably won’t be buying these foods anyway so not to worry!
