I think fizzy must be limited to 1 a day (be diet and caffeine free). . . . and not with food but it was just so irresistible today !
I thought I would look around at the subject of Fizzy and RNY ~ found some interesting reading this is taken from "Why Carbonated Beverages are "TABOO" after bariatric Surgery" By: Cynthia Buffington, Ph.D (but reworded and cut down by me to help ME understand it !!)
If you consume a fizzy while eating, the carbonation forces food through the stomach pouch, reducing the time food remains in the pouch. The less time food remains in your stomach pouch, the less satiety you feel leading to you eating more food (possibly). Some claim (though I cannot find any definitive research) that the gas in fizzy drinks may "stretch" your pouch. Food forced through the pouch by the fiz can (allegedly) significantly enlarge the size of your stoma (the opening between the stomach pouch and intestines of patients who have had a RNY or biliopancreatic diversion). An enlarged pouch or stoma would allow you to eat more. Fizzy drinks may also cause weight gain by reducing the absorption of dietary calcium. Dietary calcium helps stimulate fat breakdown and reduce its uptake into adipose tissue. Epidemiological and clinical studies have found a close association between obesity and low dietary calcium intake. Recent studies have found that maintaining sufficient amounts of dietary calcium helps to induce weight loss or prevent weight gain following diet.
The high caffeine in fizzy drinks may reduce the absorption of calcium into the body. Studies have found that caffeine increases urinary calcium content, meaning that high caffeine may interfere with the uptake of dietary calcium into the body.
Fizzy, such as Pepsi and Coke (diet or with sugar), may also cause calcium deficiencies from the high amounts of phosphoric acid that they contain. Phosphate binds to calcium and the bound calcium cannot be absorbed into the body.
Drinking fizzy may also reduce dietary calcium because these beverages replace milk and other nutrient-containing drinks or foods in the diet. Carbonated beverages, then, may reduce dietary calcium because of their high caffeine or phosphoric acid content or because drinking such beverages tends to reduce the consumption of calcium-containing foods and beverages. Such deficiencies in dietary calcium intake may be even more pronounced in Bariatric surgical patients.
Calcium deficiencies with Bariatric surgery have been reported following gastric restrictive and/or malabsorptive procedures. The reduced amounts of calcium with RNY may occur as a result of low nutrient intake, low levels of vitamin D, or, for patients who have had gastric bypass pr the biliopancreatic diversion (with or without the duodenal switch), from bypass of the portion of the gut where active absorption of calcium normally occurs. Drinking fizzy may further increase the risk for dietary calcium deficiencies and, in this way, hinder maximal weight loss success.
For all the reasons described above, including calcium deficits, reduced satiety, enlargement of pouch or stoma, drinking fizzy, even those that are sugar-free, could lead to weight gain. Fizzy that contains sugar, however, pose a substantially greater threat to the Bariatric patient in terms of weight loss and weight loss maintenance with surgery.
In addition to the adverse effects that carbonated drinks have on weight loss or weight loss maintenance, carbonated beverages may also have adverse effects on health. Soda beverages and other carbonated drinks are acidic with a pH of 3.0 or less. Drinking these acidic beverages on an empty stomach in the absence of food, as Bariatric patients are required to do, can upset the fragile acid-alkaline balance of the gastric pouch and intestines and increase the risk for ulcers or even the risk for gastrointestinal adenomas (cancer).
Well guys it looks like it’s back to water for me ! ! x x x
