Coffee and Cigarettes Stimulate Digestion: What’s The Truth Behind Grandma’s Myth?

Coffee and cigarettes stimulate digestion. At least that’s what Grandma used to say. Is there something to it or is it just a myth?

1. Effect of coffee on digestion

Coffee contains about 80-100 mg of caffeine per cup. On the one hand, caffeine has a stimulating effect, but on the other hand it should also help to digest faster.

Definitely: Coffee increases the ability to contract in the small intestine, but regardless of its caffeine content. Ingredients that promote the effect include acids, tannins and bitter substances. In a study with mice, the researcher Xuan-Zheng P. Shi discovered that coffee stimulates digestion by feeding them coffee. After only three days, he was able to determine an increased contractility, i.e. a contraction of the muscles, in the small intestine of the four-legged friend. As a result, the food pulp was mixed faster and digested just as quickly.

So we can definitely speak of an effect on digestion with coffee – whether with or without caffeine. However, how strong the effect is in the end is individual. But what about cigarettes?

2. Effect of nicotine on digestion

Cigarettes are also said to boost digestion. However, they have less of a direct influence on our intestines and much more on our brain and the autonomic nervous system.

So this part of Grandma’s myth is also true. However, it should be borne in mind that other foods can also have a digestive effect without the body having to be supplied with toxic nicotine. The health aspect should not be disregarded – cigarettes can endanger your health and promote diseases.

3. Health aspects

In order to boost your digestion, it is not necessarily advisable to reach for a cigarette. The contained nicotine and other harmful substances can endanger your health and, for example, lung diseases
However, coffee has more benefits than just boosting digestion.

Carbon Dioxide is Unhealthy: What is The Truth About The Health Myth?

Still water or sparkling water – what is healthier? Many people ask themselves this question again and again, after all there are many myths surrounding the harmfulness of sparkling water. But what about the arguments against carbonic acid in the water?

Carbonated Water Has Lower pH: What Does That Mean?

A special feature of carbonated water: it has a lower pH value. According to Stiftung Warentest, its pH value is around 5.3, while still water has a neutral pH value of 7. So carbonated water is slightly acidic – that’s one of the reasons why it’s said to be unhealthier and has numerous effects on the body could have.

#1. Carbonic acid is bad for your teeth: What’s behind the myth?

A common belief is that carbon dioxide damages teeth. According to Stefan Zimmer, Head of the Department of Tooth Preservation and Preventive Dentistry at the University of Witten/Herdecke, this accusation is completely unjustified. There are no disadvantages for the teeth when drinking sparkling water, since the carbon dioxide in it breaks down immediately.

A sip of sparkling water after a meal can even help to remove tooth decay-promoting substrates. The rinsing effect can also dilute acids that attack the teeth and tooth erosion

The American Dental Association also disagrees with this argument – ​​it considers carbonated mineral water to be safe. She cites a study

#2. Sparkling water makes you fat: Does carbonic acid increase your appetite?

Fizzy water may promote weight gain, according to a 2017 study. Researchers observed that rats given fizzy drinks gained weight faster than rats fed the same non-fizzy drinks. Apparently the carbonic acid raised the ghrelin level. Ghrelin is an appetite-stimulating hormone

However, the scientists only used rats and 20 students for their study. The results are therefore not meaningful, says Stiftung Warentest. So far there is no reliable evidence that sparkling water can actually make you fat.
Experts advise your own appetite in connection with sparkling water

#3. Carbonated water makes you acidic: Does the drink disturb our acid-base balance?

As already mentioned, sparkling water actually has a higher pH value than still water and is therefore more acidic. With this reason, carbonated drinks are sometimes discouraged in naturopathy.

However, the German Society for Nutrition (DGE) gives the all-clear: “The carbon dioxide it contains is quite unstable and quickly breaks down into its components CO2 and water”. When the bottle is opened, the carbonic acid escapes with a hiss (in the form of CO2). “The rest breaks down in the stomach. This means that you have to belch or a part gets into the blood via the digestive tract and is exhaled unnoticed through the lungs. So carbonated water does not contribute to acidification of the body.”

But even in this case, according to the Center for Health, there is no clear answer. So it means here too: observe oneself. For some people, carbonic acid can affect pH balance. This can lead to heartburn or digestive problems. For others, the sparkling water can even have the opposite effect. In the case of constipation, carbonated water could even be more advisable than still water.

#4. Carbonic acid damages the stomach: does sparkling water cause heartburn?

The fact is: Anyone who drinks carbonated drinks absorbs gas (CO2) – and this also finds its way out again. According to NDR experts, part of it enters the blood via the digestive tract and is then exhaled via the lungs.

The rest then escapes through belching and annoying flatulence. As a rule, however, this is not a problem – according to the experts, sparkling water is not automatically unhealthier because of this.

But be careful: If you are prone to heartburn, you may well have problems if you drink carbonic acid. When you belch, stomach acid can get into the esophagus and cause heartburn. Therefore, people with sensitive stomachs should drink water that is still or only slightly carbonated.

Conclusion: Carbonated water is not necessarily unhealthier – the effect is individual

In summary, it can be said that carbonated water is not nearly as bad as its reputation suggests. In most points it depends on the individual sensitivities of a person. So if you don’t notice any negative effects on yourself when you drink sparkling water, you can confidently continue to do so.

Myth or Fact? Reheated Pasta Has Fewer Calories

Noodles can be combined in many ways and are a popular food; the problem for many: They are relatively calorie-dense. Warmed up noodles should have fewer calories.

Things worth knowing about pasta

Noodles come in many different forms. There are also numerous ways of preparing it: whether casseroles, one-pot dishes or a soup, noodles can be used in many different ways. According to extras, around 9.5 kilograms of pasta were consumed per capita in 2020.

According to surveys, spaghetti is one of the most popular types of pasta in Germany. Around 33% said spaghetti was their favorite type of pasta. This is followed by gnocchi, cannelloni, tortellini, rigatoni, tagliatelle, ravioli and, in 8th place, penne.

Noodles are often associated with the reputation that they are thick eaters. Noodles can certainly lead to weight gain if you eat them too often and in large quantities, if you eat an unbalanced and unhealthy diet and if you don’t exercise enough. Cooked white flour pasta has an average of 150 calories per 100 grams, wholemeal pasta around 140 calories. So it’s the quantity that counts: If you choose 150 grams of cooked pasta as a side dish with a vegetable dish, for example, this is just around 220 calories. In addition, there are now numerous alternatives to white flour pasta on the market, which often also provide more nutrients and fiber. These include, for example, corn noodles, spelled noodles, noodles made from lentils or chickpeas as well as gluten- and calorie-free konjac noodles.

Saving calories when reheating pasta

The statement that noodles have fewer calories when warmed up is basically true; however, it must always be borne in mind that the “savings” show up to a very small extent. The reason for the reduced number of calories lies in the so-called resistant starch: This is produced when heated, starchy foods such as pasta, but also potatoes, for example, cool down. The resistant starch is one of the dietary fibers and ensures that we stay full longer, but also that the calorie content drops.

The so-called resistant starch has only about half the calorie content of the “normal” starch it contains. This is because not all of the starch it contains is converted to resistant starch; this only happens with a relatively small amount of starch.

Caution is advised with resistant starch: it passes through the small intestine undigested. If you otherwise eat little fiber and now very large amounts of indigestible starch, you may experience abdominal pain, bloating, constipation or diarrhea. It is therefore important to include high-fiber foods in the diet in everyday life and to increase the intake slowly and in a controlled manner.

Myth: Pasta Water Without Salt Boils Faster

Does salt belong in the pasta water? If so, when and how much? There are many myths circulating on the subject. We explain to you what really matters when it comes to salt in pasta water.

Preparing noodles is very easy: Boil water in a pot, put noodles in, cook noodles. But many wonder how much salt is needed and when to add it – right at the beginning in the cold water or as soon as it boils? All in all, the salt in the pasta water can affect three factors: the taste of the pasta, the boiling point of the pasta water and the cooking time. Let’s take a closer look at each factor.

Salt in the pasta water: why the timing is still interesting

Nevertheless, it makes a difference whether you add the salt to the cold or boiling pasta water. Salt dissolves better in hot than in cold water. Therefore, when you add the salt to the cold water, a larger amount that doesn’t immediately dissolve will sink to the bottom of the pot. There the salt causes stains and can damage the pot in the long run.

Tip: Stainless steel pots are much more robust than aluminum pots. Salt doesn’t do much harm to the former.

Pasta water: salt and its effect on cooking time and taste

The Max Planck Institute says: No, salt in the pasta water does not significantly affect the cooking time. So why would you salt the pasta water at all? The answer is: for the taste.

Salt in the pasta water ensures that the pasta retains its flavor. Behind this is a relatively complex physical phenomenon called osmosis. Put simply, you can imagine it like this with pasta water: If the water is completely unsalted, the salt concentration in the pasta is higher than in the pasta water (pasta naturally contain minerals such as sodium). The system wants to compensate for this concentration gradient. This is why minerals from the pasta go into the cooking water. The result: the noodles lose their taste. On the other hand, if you salt the pasta water well, the pasta can even absorb salt.

A matter of taste: How much salt in the pasta water?

You can decide how much salt you add to the pasta water according to your taste. A simple rule of thumb is: ten grams of salt for 100 grams of pasta and one liter of water.

Another tip comes from chef Sami Nosrat (author of the book Salt, Fat, Acid, Heat): salt the water until it tastes like sea water.

Salt in Pasta Water: Does It Affect Nutrient Content?

Unfortunately, the question of whether salt in the pasta water influences the nutrient content of the pasta has not been conclusively answered. Intuitively, the section on osmosis would tell us that salted pasta water is beneficial because less of the material in the pasta migrates into the water. However, the difference may be insignificant or other factors that have not previously been considered play a role.

But with these tips you will have a nutrient-rich meal in any case:
Use whole wheat pasta instead of white flour pasta. The former contain more fiber, minerals and vitamins.
Whether with or without salt: when cooking, water-soluble nutrients are transferred from the pasta to the pasta water. This applies, for example, to B vitamins. You can save part of it by enriching the pasta sauce with the pasta water. The pasta water also contains starch from the pasta, which binds your sauce. And since you salted the pasta water well, it also adds flavor.
