Vegetables: Acidic as Soda?

The University of Dundee has determined that oven-roasted Ratatouille is as acidic as many carbonated drinks. Ratatouille is a traditional French Provençal stewed vegetable dish made up of tomatoes, onions, zucchini (courgettes), eggplant (aubergine) and sweet peppers (capsicums) (via wikipedia).

Their research found that, however it is cooked, ratatouille is acidic. But, oven-roasting significantly increases the acidity compared to the more traditional stewed version of the dish, to the point where it is as acidic as some carbonated drinks.
Wonders will never cease. This is what a school of dentistry does when it has too much time on it's hands! However it does lend credence to the idea that vegetarians have a higher risk of dental erosion. Many fruits (citrus in particular) also tend to be quite acidic.

This is no excuse to feel wary of oven-roasted vegetables. The only vegetables that gained acidity were aubergines, green peppers and courgettes. Red peppers were more acidic when stewed.

This may be true, but you don't see people munching ratatouille all day, every day for good portions of their lives like you see with soda. Most people who drink an occasional soda won't have problems with tooth erosion, just like most people who eat ratatouille every so often probably won't have any problems.

This news will NOT make me go back to hamburgers, french fries, pizza, and milk chocolates. This is a simple thing that we need to go more raw on the vegtables.

Common sense. Don't pay attention to these so-called alkaline-acid diets.

Each people have their own metabolic type. The metabolic type depends on how much meat vs. vegetarian they need to eat. However, EVERYBODY needs animal protein. Soy products are plain bad for you. Period, contrary to what the USDA said. The USDA MyPyramid food guide pyramid is based on shoddy work. They say you need grains for your health. Believe me. Grains, even whole grains, are just as bad as smoking cigarettes. They are addictive. Follow the food guide pyramid, and you will develop carb addictions, gain weight, and become a diabetic.

Diabetes is curable. First, cut off on fried foods, sodas, processed foods, and refined grains. This is a great start. Trans fats, canola, soybean, cottenseed, and corn oil elimination greatly improves insulin sensability. Start exercising.

Usually, the American Diabetic Association puts diabetics on a Low-fat, moderate protein, high carbohydrate approach to treat the disease. However, this approach is obsolete. A New approach now covers a moderate-fat, high protein, low to moderate-carb, high fiber diet, with no trans fats, processed foods, or artificial ingredients or added sugars or grains of any kind in the food. Carrots are allowed, but potatoes and pasta is forbidden. Fish oil, flax oil, olive oil, grapeseed oil, clean animal fat, butter, coconut oil, and palm oil can be used, but stuff like canola oil, cottenseed oil, soybean or vegtable oil, or corn oil is strictly forbidden. Make sure that the oils you buy are organic and extra virgin if it is a plant based oil, or came from grass-fed animals if it is an animal based fat or oil. Never used bleached, refined, and deoderized oils or ANY margarines or shortenings. They are bad for you.

As you follow this diet, your blood sugar and insulin levels will improve, you will be taken off medication, and any damaged organs will slowly heal. Don't get a lazer done if you have retinopathy, as it will cause scar tissue that complicates the healing process. Intervenious chelation theorpy can be done to clear up any gunk in your arteries, however, your arteries will slowly heal on their own on an improved diet.

But anyways, people need to eat more organic varietys of vegtables and fruits, and farmers need to better grow them. The way we are cropping our foods and raising our livestock today is slowly distroying the planet, putting people into hospitals, and causing numerous diseases. It's time for people to stop using pesticides, have better crop rotation, use organic material, and put animals back onto pastures and stop feeding them grains on feed lots. Americans will be a whole lot healthier that way.

This is an excellent website which provides non-judgemental information about all manner of different techniques of healthy living and weight loss. There are quite often comments from generally young women who clearly have problems and want to be unrealistically thin which are very sad to read, I hope they take on board the sensible advice given here. What are more disturbing are the increasingly dogmatic comments from people such as James, above, who constantly touts his own method, dismissing all others and suggesting a diet which many people would not find particularly healthy and involves ingredients which are both extremely expensive and, for most people, not that easy to find. Losing weight shouldn't be about forbidding things, talking about addiction and hammering home your own viewpoint at the expense of other people's, often valid advice.

I realise this is a forum for debate, but it angers me to read some people repeating the same things again and again in a way which does not stimulate discussion but aims to stifle it by enforcing one particular opinion.

Also, his spelling and grammar is atrocious.

This is why eating raw is much better for you than cooking your food. Enzymes are destroyed when anything is cooked above 118 F.

But even if you do eat cooked Ratatouille, it is much better for you overall than a can of soda. Studies such as the one done at the University of Dundee, and then the way the results are reported anger me because they are misleading. Some people will now rationalize that if Ratatouille isn't that good, then soda can't be that bad...therefore I can drink more of it.

Also, the article on the U of D web site makes it sound as though the acidity in soda is the only contributing factor to tooth decay, I'm sure the high sugar content has nothing to do with it.

Conclusion: Don't drink soda and eat raw veggies!

Whole grain maybe bad for you. But not for me.
I am from Germany. Whole grain bread has a great tradition there and IS NOT just a new "health trend-food" like I perceive it to be here in the States. I have been eating this stuff for all my life and my parents, too. They are healthy. I am healthy and an athlete.

And soda is plain disgusting. If anybody drinks this stuff they have to accept the consequences.

Mix fresh fruit or vegetable juice with sparkling or still water. That works well.

Katy,

Grains are either healthy for all humans or they are not.

The advent of agriculture is only a blip on the human evolutionary scale.

What fresh fruit are you talking about ? Natural wild fruit, low in sugar and high in fibre, or the fruit that has been selectively bred to be high in sugar and low in fibre ? Irradiated and treated with chemicals ? This second kind is the only thing available to most of us.

lowcarb dave,

I disagree heartily about espousing a particular diet that is the ONLY healthy diet for ALL people. And it is NOT true that "Grains are either healthy for all humans or they are not." Humans have thrived for bazillions of years by eating the local foods available. Fish is healthy, but people who live inland can't get fish for their diet, but are healthy nevertheless. Veggies and grains are healthy, but the folks who live in the frozen tundra north can't grow veggies or grains, and have thrived for bazillions of generations without veggies or grains. Vegetarian societies eat lots of veggies and grains and have thrived for bazillions of generations without eating animal meat. Milk is a healthy food, and nomadic societies as well as others have thrived for bazillions of generations with milk products as a LARGE part of their diet. Other populations lose the ability to digest milk after weaning, and it's ok for them to NOT include milk in their diet.

For heavens sake, can't we allow people to make up their own minds about what's healthy for them, and quit harranging people about what a "PROPER" diet consists of?

I grant you that sugar-laden and artificial-chemical-laden foods are not good substitutes for fresh foods, but harranging people about what YOU think are "good" foods and which are "bad evil" foods is not going to get them to improve their diets.

Can we lighten up here and make friendly suggestions without the harranging, please? Thanks.

Rheanna,

This is a blog site about diets, so different people's opinion of what is optimal will arise form time to time.

Quoting you:-
"For heavens sake, can't we allow people to make up their own minds about what's healthy for them, and quit harranging people about what a "PROPER" diet consists of."

I agree, tell that to our respective governments!

This type of pseudo-science is useless for most of us trying to make informed decisions. As Spectra pointed out, the consumption of oven-roasted Ratatouille doesn't compare mathematically to carbonated drinks. Sort of like the days when rats would get cancer from cyclamates if they consumed the human equivalent of 40 cases of soda a day.

Some vitamins acidic so vegetables weather cooked or not would be.
Doesn’t this mean you just need to brush your teeth after eating Ratatouille?
I really feel the study was a non issue.

I eat what my nutritionist advises me to eat and what I like, given the fact that I am exercising more than 6 days a week. I run marathons and lift weights and I run very well eating the stuff I eat, Buddy. I also eat loads of carbs (the right ones).

I am talking about the best fresh fruit I can find in my local store, which is usually not treated with chemicals.

Other people, other cultures, other diets. Deal with it.
