There’s this fascinating “kitchen experiment”. Take a “brick” of baker’s yeast (not dry yeast), and a couple teaspoons of sugar, put them together in a cup and stir together. There’s no doubt both are solids: yeast is a firm block, you must use quite a bit of force initially to crush it and even then it should remain a rather thick paste. The sugar is crystals, nothing tricky about that. And then, within a minute or so of stirring, your cup contains only liquid – not entirely fluid like water, but not much thicker than cream. Solid+Solid -> Liquid.
What process leads to that? What happens with the baking yeast when it comes in contact with sugar, that it turns from solid to liquid, and releasing enough water to dissolve the sugar?
1 Answer 1
The whole process is called osmosis. In it there is the flow of liquid along a concentration gradient. Water then flows from the side which contains the low concentration of dissolved molecules (this can be salts or sugar for example) to the side with the higher concentration until it reached equilibrium. This principle is shown in the image below (all images from the Wikipeadia article on osmosis):
The blue dots are the dissolved material, the concentration is high on the right side and lower on the left. Through the dotted line in the middle (which is a semi-permeable membrane) only the solvent can pass to reach a concentration equilibrium. There is a pretty cool osmotic pressure simulator available on Molecular Logic which can also help understanding the principle.
And this is exactly what happens to the yeast cells. The sugar crystalls get dissolved (at least partly) by some of the humidity from the yeast block (this will not work with dried yeast) and form a highly concentrated sugar solution (also called hypertonic). The sugar concentration inside the cells is relatively low (called hypotonic). This leads to the effort to balance the concentration inside the cell and outside of it which then leads to a massive efflux of water from the cells. This goes so far, that the cell membranes break and the interior of the cells is released (nucleus, DNA, proteins and so on) and the sugar is completely dissolved in the released water. The reason why this mixture is so “gooey” afterwards is the DNA, which forms long, thick strains.
This method can be used in the lab to break up cells relatively gently without applying too much force.
When baking you should make sure, that your yeast is not coming directly into contact with undissolved sugar (or salt which works the same way), as this will kill a part of your yeast cells. However, for baking you usually dissolve the yeast in water or milk, so there is a huge excess of water which dissolves the sugar (or salt) and protects the cells. Addionally your yeast is much better distributed in the dough and gives better results.
How to get rid of a yeast infection.
If you’re a woman, you’ve got a pretty good chance of experiencing a yeast infection at some point in your lifetime. Vaginal yeast infection, or candidiasis, is a very common condition and can cause skin rashes, itchiness and irritation, and strange-looking discharges. It can be an embarrassing and uncomfortable condition to have, but luckily, it’s very treatable and typically goes away in just a few days with medications. Knowing the symptoms and what to look for are important to be able to diagnose and treat them quickly. Below are answers to some common questions about yeast infections.
What Is A Yeast Infection?
Different parts of your body, including your mouth, moist parts of your skin, and your digestive tract, contain a natural balance of yeast, candida albicans (a fungus), and bacteria. Most of the time, this balance remains in check, with the good bacteria in your body keeping your candida levels under control. But when the balance of candida, yeast, and bacteria are off, candida can overgrow in these areas and cause a yeast infection to occur. If left untreated a yeast infection could take up to two weeks to go away and may end up returning.
Who Can Get Yeast Infections?
Yeast infections are common in women. Three out of four women will have a yeast infection at some point in their lifetime, with many women having two. Men can also get yeast infections, although they are somewhat less likely to get a yeast infection than women. A man is more likely to get a yeast infection on his penis if he is uncircumcised since the area under the foreskin can be a breeding ground for bacteria.
Some people may be more prone to yeast infections. Using certain medications, having diabetes, being pregnant, or having a lowered immune system can make a person more likely to get a yeast infection.
People who wear tight-fitting clothing are also more likely to experience yeast infections since it creates a warm, moist environment that allows the growth of yeast and bacteria to thrive.
What Are The Symptoms Of A Yeast Infection
Signs of a yeast infection include vaginal itching, swelling, redness, painful sex, and a white, clumpy discharge that looks similar to cottage cheese. In some cases, yeast infections can also cause vaginal sores
How Do You Get A Yeast Infection?
Anything that disrupts the natural balance of yeast, candida, and bacteria can have the potential to lead to a yeast infection. Some things that may increase your chance of getting a yeast infection are:
Use of antibiotics (since antibiotics can kill the good bacteria that keeps candida and yeast in check)
Having higher levels of estrogen (pregnant women, those taking birth control pills, or those taking hormone replacement therapy)
Not changing out of wet clothes, like a swimsuit or gym clothes, can create prolonged moist environments for yeast to grow.
Regularly douching in women
Using scented feminine products
Yeast infections are not considered sexually transmitted diseases and are unlikely to be contagious in most cases. However, those who are prone to yeast infections, or who have a lowered immune system, may be able to contract a yeast infection from someone else through kissing, breastfeeding, or sexual intercourse.
What’s The Difference Between A Yeast Infection And A UTI?
While some of the symptoms between a UTI and a yeast infection are similar, they are two distinct conditions. A UTI occurs when bacteria invade the urinary tract, causing pain when urinating, feeling a frequent need to urinate, and foul-smelling urine. UTI’s may also lead to fever, lower back pain, and even nausea or vomiting when serious.
While yeast infections also can cause pain when urinating, you’ll also likely feel itchiness and swelling around your vaginal area too, and instead of foul-smelling urine, you might experience an odorless white discharge.
Although the two are unrelated, sometimes, treatment for a UTI, which often involves taking antibiotics, may actually lead to a yeast infection, since antibiotics can kill off the good bacteria that keep yeast growth in control.
How Do You Get Rid Of A Yeast Infection?
While a mild yeast infection may go away on its own, it’s rare for that to happen. If you experience symptoms of a yeast infection for 3 days or more, it’s important to get it treated.
The quickest, and most effective way to get rid of a yeast infection is to get a prescription from your doctor. There are several types of medications that can treat yeast infections. These include antifungal creams or ointments, tablets, or even suppositories.
Depending on what your doctor prescribes, you may be required to take or apply your medication for as little as 1-3 days, or for longer if your infection is more severe. Most mild-moderate cases of yeast infection can be cured in as little as 3-7 days.
There are many over-the-counter products available to treat yeast infections.
Home remedies for yeast infections
For those who want to try a more natural approach to treatment, things like tea tree oil, coconut oil, garlic, oil of oregano, or even yogurt have shown some signs of effectiveness. However, these treatments are spotty and you should still talk to your doctor about using a home remedy, as some herbs and natural supplements can interact with other medications you may be taking. In addition, it’s always helpful to receive a complete diagnosis from your doctor in case your condition isn’t a yeast infection or is being caused by another underlying condition.
What If I Keep Getting Yeast Infections?
A yeast infection is considered to be chronic if you get one four or more times within one year. The same things that can contribute to normal yeast infections can also cause them to be chronic – taking regular medications, hormone therapy or pregnancy, or having a condition that affects your immune system.
In cases of chronic yeast infections, your doctor will likely prescribe you a longer-term therapy to treat the infection and may recommend a maintenance therapy to keep it from coming back. He or she will also talk to you about behavioral changes you can make that may help to prevent yeast infections from occurring, such as wearing breathable, loose-fitting clothing, changing out of wet clothes as soon as possible, and avoiding certain products that may disrupt the natural environment of the vagina, such as douches or perfumed vaginal products.

Yeast allergy or Yeast Intolerance? Does this question baffle you too? If yes, you’ve headed the right way! In this article, we shall deal with the Causes of Yeast Intolerance, its symptoms, and Ayurvedic and Natural treatment against Yeast Intolerance. But foremost let’s understand the difference between Yeast Allergy and Yeast Intolerance.
Difference Between Yeast Intolerance and Yeast Allergy
Causes of Yeast Intolerance
Causes of yeast intolerance, as mentioned above may vary from those of a yeast allergy, but in some cases, a yeast allergy may also trigger yeast intolerance so all foods that are fermented, processed, or aged might be the causes of yeast intolerance. Sugary foods may also cause this condition. Foods that may lead to yeast intolerance are:
- Baked food items.
- Dried fruits.
- Cured and processed meats.
- Processed or packaged fruit juices.
- Blueberries, blackberries, strawberries, and grapes.
- Brewer’s Yeast – alcohol. (beer, wine, ciders, etc.)
- Aged cheese.
- Ingredients containing vinegar such as olives, pickles, etc.
- Buttermilk, soy milk, non-dairy cream, yogurt.
- Citric acid.
- Stock cubes, gravies, stock.
- Cereal products,
- Soy sauce, tamarind.
Symptoms of Yeast Intolerance
Discomfort, indigestion, and inflammation are the initial Symptoms of Yeast Intolerance. Following are a few more:
- Weight gain.
- Breathing issues.
- Severe headaches.
- Body ache.
- Pain in joints.
- Itchy skin, rashes, etc.
- Abdominal pain.
- Menstrual disbalance
- Extreme Constipation or Diarrhea
Yeast-Free Foods or Alternatives
Eliminating yeast-containing foods or drinks from the diet significantly contributes to treating the intolerance. But doing so while maintaining the nutrition value of the diet becomes a task. Let’s take a look at the alternatives that provide the same nutritional value but are yeast-free:
- Brown rice
- Skimmed milk
- Green vegetables
- Unprocessed fish or meat
Treatment of Yeast Intolerance Naturally
Ayurveda is acknowledged and known for treating the underlying cause of infections and diseases. Treat Yeast Intolerance Naturally with a few steps mentioned below:
1. Ayurvedic Detox:
Treating yeast infections and intolerance by detoxifying the body by practicing panchakarma is a magical remedy. Virechana (medicated purgation) and Vasti (medicated enemas) eliminate toxins by purging the intestines and then restoring good bacteria and fungi.
2. Ayurvedic Herbs:
Ayurvedic herbs that are highly beneficial for treating yeast intolerance are:
- Neem (Azadirachta indica)
- Asafoetida (Ferula assa-foetida)
- Garlic (Allium sativum)
- Musta (Cyperus rotundus)
- Licorice (Glycyrrhiza glabra)
- Guduchi (Tinospora cordifolia)
