Carbohydrates, Anyone??


I'd never heard this before; anyone...??

"High calorie intakes, especially as carbohydrate, increase carbon dioxide production (VCO2) and may precipitate respiratory failure in patients with severe pulmonary disease. Energy obtained from fat results in less carbon dioxide and thus may permit a reduced level of alveolar ventilation for any given arterial blood carbon dioxide tension (PaCO2)."

Conclusion of the study: "Comparatively small changes in the carbohydrate and fat constitution of meals can have a significant effect on VCO2 [carbon dioxide production], exercise tolerance, and breathlessness in patients with chronic obstructive lung disease."

Hi this sounds interesting where did you read about this.? I have never heard of it before but it's worth looking into. Thank you so much for posting this. 😊 Bernadette xxx

Also..., having done a bit of research now on what foods I can and cannot eat..., I doubt I'll be trying to follow a low carb diet; no oats, can't eat some of my fave fruits, bread's out, and only plain yogurt...., "BUMMERVILLE" !!!

Exercise is an important part of overall health. People should avoid a sedentary lifestyle but refrain from excessive exercising.

The Centers for Disease Control and Prevention (CDC) recommend that adults do moderate exercise for 150 minutes a week for a minimum 10 minutes at a time for moderate health benefits. For optimal health benefits, the CDC recommend 300 minutes of exercise. The CDC also suggest that people lift weights or do other strength training exercises to improve overall health.

Those on low-carb diets may want to avoid long periods of intense activity such as distance running. This is because people who are doing a form of exercise that requires extra endurance, such as marathon training, will need extra carbohydrates to fuel their bodies.

Morning Hun, Just read your Link, Well I tried. It is too medically toned for me, so, I will carry on with limited carb's as I do, and will not try to read it again.. Thanks Anyway for sharing. xxxx


I think that this links in with what we are all supposed to know now. Sugar is bad! My grandaughter is type one diabetes and it is the carbs which we count, not the fat. The carbon dioxide link to this is very interesting. However, all of this is relative. If I eat any less carbs or fat than I manage to push down my throat now I will disappear.

There are various bi products of metabolism. Obviously the only answer is a balanced diet. My worry about this short of study is that it only looks at the short term and one particular aspect of the metabolic process. My question would be what are the medium and long term affects of a diet high in fats. Could we be helping one issue of COPD only to increase the risks to other body systems?

Take care with highly acidic foods like pickles and sweet/sour sauce which contains vinegar. We blow acids off when breathing out to keep the blood at optimum ph, but if breathing is compromised, that's not so automatic and can cause problems. As said above, moderation is the key.
