Spices have for centuries been hailed not only for their flavor but also for their healing powers. From Ayurvedic potions of old to new-fangled wellness fads, the popularity of natural remedies like ginger, garlic, and turmeric keeps increasing. Yet as more individuals turn to turmeric shots or add raw garlic and minced ginger to their meals in large quantities, a sobering question must be asked: Do these potent herbs and spices cross with your prescription medication?
Recent studies and expert opinions indicate that although these natural compounds provide various health advantages, overindulgence — particularly in supplement form — may present unforeseen effects upon combination with routine medications.
Turmeric, ginger, and garlic are all known for their anti-inflammatory and antioxidant properties. They’re used to alleviate everything from indigestion to joint pain, and even in the management of chronic diseases. But just like pharmaceutical drugs, these spices contain biologically active compounds that interact with the body’s systems — and potentially with medications.
For example, the active ingredient in turmeric, curcumin, is acclaimed for its anti-inflammatory properties and its ability to enhance the immune system. However, curcumin can thin the blood and reduce blood sugar levels when taken in excessive amounts, posing complications to individuals taking blood-thinners or diabetes medications.
Similarly, ginger, revered in both Eastern and Western practices for its digestive benefits and anti-nausea effects, can increase bleeding risk and cause arrhythmia in people with heart conditions if consumed in excess.
Garlic, known for its powerful antibacterial and antiviral qualities, can impact liver enzymes and enhance the effects of anticoagulants, thus raising the risk of bleeding.
Turmeric has attained superfood status for a reason. Its anti-inflammatory properties have made it a staple for relieving joint pain, metabolic syndrome, and even for preventing cancer. Those same characteristics, though, can be detrimental when consumed in high amounts.
Overconsumption of curcumin — particularly in supplements — may lead to gastrointestinal problems such as constipation, bloating, and acid reflux. More seriously, turmeric contains anticoagulant properties, which means it may interfere with blood clotting, particularly when accompanied by medications like aspirin, warfarin, or clopidogrel.
High doses of turmeric have also been found in some case studies to interfere with the way the liver metabolizes drugs, changing their effectiveness or enhancing side effects. Professionals suggest keeping turmeric consumption to a maximum of 3 grams per day, which is easily obtained through ordinary cooking.
Ginger is another spice frequently used to alleviate gastrointestinal distress, lower inflammation, and avoid nausea. Large quantities, however — greater than 4 grams a day — can result in heartburn, mouth burns, and even diarrhea.
Its anticoagulant properties, while healthy for cardiovascular well-being, are hazardous when taken together with prescription anticoagulants. Ginger also interacts with drugs taken to control high blood pressure and diabetes and can either accentuate or attenuate their effects.
Individuals undergoing surgery are also instructed not to take ginger supplements prior to surgery for a few days in order to minimize the chances of excess bleeding.
Garlic has been most commonly used for its cholesterol-lowering, blood pressure-controlling, and infection-fighting capabilities. Its major constituent, allicin, is very active but also tends to interfere with medication metabolism.
Overconsumption of garlic will enhance the action of anticoagulants, exacerbate the risk of gastrointestinal upset, and interfere with HIV/AIDS treatment and some anti-cancer therapies. Research indicates the optimal dose to benefit from garlic without loss of safety is between 1 and 2 cloves daily (3–6 grams).
High-dose supplements pose the most risk and need to be taken carefully, especially by those with complicated medication regimes.
Cloves are bursting with eugenol, a substance with anti-inflammatory, antimicrobial, and anesthetic qualities. They have been used traditionally to treat toothaches, soothe digestion, and even benefit the liver. But although the advantages are significant, so are the dangers — particularly for those taking some medications.
The eugenol is a strong substance that also serves as a natural blood thinner. This characteristic, although desirable under certain circumstances, can be hazardous to patients using anticoagulant drugs like warfarin or aspirin. In excess, cloves have the potential to enhance the effects of such drugs, an effect that increases bruising or internal bleeding risks. In addition, because eugenol thins the blood, medical practitioners generally instruct patients to desist from clove oil or supplements containing cloves at least two weeks before undergoing any surgical operation in order to reduce complications from compromised blood clotting.
Another less well-known issue is the effect of cloves on blood glucose levels. Research indicates that cloves can reduce blood glucose, and when taken with diabetes medications, could increase the risk of hypoglycemia, a condition characterized by dizziness, sweating, and fatigue. Therefore, diabetic patients should be particularly vigilant and consult a medical practitioner before using cloves in medicinal amounts regularly.
Although general culinary use of whole cloves in tea or food preparation is safe, concentrated oil of cloves and supplements must be used cautiously. It is recommended by experts to take less than 2.5 mg/kg of body weight per day of clove oil, and avoid prolonged use except under medical advice.
Cinnamon has been traditionally extolled for its warm flavor and health-promoting virtues — notably Ceylon cinnamon, commonly known as "true" cinnamon.
Famous for its power to assist in balancing blood sugar, lowering inflammation, and also acting as a natural sweetener, it is now found in popular use in both kitchens and health foods. But one must take care to separate Ceylon from the more widely available Cassia cinnamon, which has much higher coumarin content, a chemical connected with possible health threats if taken in great quantities. To avoid risk, one should be aware of dosage.
As per the European Food Safety Authority (EFSA), the amount of coumarin consumed must not be more than 0.1 mg for each kilogram of body weight on a daily basis. This accounts for about ½ to 1 teaspoon of Cassia cinnamon per day for a typical adult. For those who consume cinnamon on a regular basis — particularly in health supplements — Ceylon cinnamon is the better choice, as it has much less coumarin and is at lower risk for side effects.
Like with ginger, turmeric, and garlic, the worry lies less in using these spices as a cooking agent — and more with concentrated supplement or oil consumption, where active ingredients are extremely powerful. Most people think if something is "natural," then it can't possibly harm you. Natural, however, does not always equate to safe, particularly in combination with prescription medications.
A 2023 review in the Journal of Integrative Medicine pointed out that spice-based supplements are one of the most frequently reported natural products to cause interaction with medications, especially those with cardiovascular, hepatic, and endocrine effects.
One of the main differences health professionals point out is between the use of these spices in normal cooking and taking them in concentrated supplement form.
Although it's unlikely that food amounts of turmeric, ginger, or garlic would be harmful, supplements may provide huge doses that overwhelm the body's capacity to metabolize them harmlessly. In addition, supplements are not as strictly regulated as pharmaceutical medicines, which results in variability in potency and purity.
A University of Mississippi study found that substances such as cinnamaldehyde in cinnamon are able to stimulate liver enzymes that enhance the metabolism of drugs, possibly diminishing the efficacy of a drug. While yet to be tested in humans, this type of interaction is a good reason to be careful when adding any herbal supplement to your daily regimen.
The bottom line? Natural doesn't necessarily equate with harmless — particularly when spices are combined with prescription medications. Individuals taking medications for blood pressure, diabetes, heart disease, bleeding disorders, or cancer should always speak with their healthcare provider before initiating any herbal supplements.
Use only culinary amounts of spices such as turmeric, ginger, and garlic.
So although a golden turmeric latte or garlicky stir-fry may appear to be the healthiest option, it's always best to take the big picture into account — particularly if your medicine cabinet is at stake. After all, even the healthiest of foods have their cautionary tales. If unsure, ask your healthcare provider — and let balance be the spice of life.

Tiktok fibremaxxing wellness trend: There is no shortage of wellness trends online that claim to transform your health, but a new one has taken over social media with a focus on gut health. It’s called “fibremaxxing,” and its premise is simple: eat more fibre to improve digestion, metabolism, immunity, and lower the risk of disease. On TikTok and Instagram, the trend often appears as colourful lentil bowls, chia puddings, and smoothies loaded with leafy greens and flaxseeds. But how much of this viral trend is actually backed by science?
The idea of increasing both soluble and insoluble fibre isn’t new, yet fibremaxxing has made it trendy again—and this time, for good reason. Fibre is vital to everyday health, supporting everything from steady blood sugar to regular bowel movements. Here’s what experts say about this growing movement and why fibre truly matters.
Fibremaxxing is a social media movement that encourages people to boost their fibre intake by adding more fruits, vegetables, legumes, and whole grains to every meal. The goal is to improve digestion, promote fullness, and support long-term health. According to Dr. Urvi Shah, a board-certified hematologist-oncologist and physician at Memorial Sloan Kettering Cancer Center, the concept behind fibremaxxing is largely rooted in scientific evidence. Dr. Shah, who is leading multiple studies on high-fibre plant-based diets, notes that the approach aligns well with established nutrition research.
High-fibre diets are consistently linked to a wide range of health benefits, from lowering the risk of heart disease, diabetes, and colon cancer to aiding weight control and gut function. That’s why Dr. Shah believes fibremaxxing gets several aspects right.
She explains that including a wide variety of plant-based, high-fibre foods is essential because “different fibre types feed different microbes.” A diverse diet helps nurture a balanced microbiome. She adds that the trend’s emphasis on whole foods rather than processed or fibre-enriched items is a major plus. “Whole plants provide fibre, polyphenols, and micronutrients that work together to support the gut,” she says. Prebiotic-rich foods also help shape a healthier microbiota and increase the production of beneficial short-chain fatty acids like butyrate, which has “anti-inflammatory and anti-cancer effects.”
Simply put, upping your fibre intake through natural, unprocessed foods, rather than supplements, can make a real difference to gut health.
Experts suggest that adults should consume between 25 and 30 grams of fibre each day. Men typically require more (around 38 grams), while women need about 25 grams. These numbers can vary depending on age, sex, and calorie intake, but a general guideline is 14 grams of fibre for every 1,000 calories eaten, according to Harvard Health.
Plant-based foods are the easiest way to increase your fibre intake, this could mean starting your morning with oats or simply adding more vegetables to your meals. Dietitian Laura Tilt notes that several everyday foods are surprisingly high in fibre:
There’s no doubt fibre plays an essential role in maintaining good health. But like any nutrient, too much of it can cause problems if not balanced properly. A sudden surge in fibre intake without enough water can lead to bloating, gas, constipation, dehydration, or even trigger IBS symptoms. Over-focusing on fibre might also cause you to overlook other nutrients your body needs. The key is moderation, fibre is beneficial, but it works best as part of a balanced, varied diet.

If you landed here, the reason is that you are also someone who cannot tolerate milk, but loves yogurt, and are probably wondering why is that?
The logic is that if you have lactose intolerance, you won't be able to digest any dairy product, but with yogurt, your life is easy. The answer lies in the components of the two various dairy products that come from the same source.
The reason is because you are lactose intolerant. This is a condition that makes it hard to digest the sugar in milk and milk products, called lactose. People with lactose intolerance could have diarrhea, gas and bloating after they consume milk. While this condition is usually harmless, it can cause discomfort.
This happens because the enzymes in the small intestine, called lactase is responsible for lactose intolerance. If someone has too low levels of lactase, the person can become lactose intolerant.
The small intestine and colon are parts of the digestive tract, which processes the foods you eat. The intestine pull out nutrients from the food and whatever is not absorbed by the intestines continues along the digestive tract and is expelled as stool during a bowel movement.
The answer to this lies in the fermentation process that turns milk into curd and breaks down much of the lactose, which is the sugar, that is often difficult to digest. The probiotic bacteria used to make curd contain their own lactase, which helps in the breakdown of lactose, and this can further help with digestion even for those who do not produce enough lactase on their own.
Furthermore, during fermentation, the bacteria in curd, called the Lactobacillus bulgaricus and Streptococcus thermophilus convert lactose into lactic acid, which is easier for the body to process. This helps your body to digest curd easily over milk. Since the bacteria contains lactase, which the milk lacks, some people may find it easier to digest curd or yogurt over milk.
The bacterial cells also physically protect their lactase, and it can work to break down the lactose from the curd as it passes through the digestive system.
The key to a healthy gut health is lactobacillus, a kind of probiotic, which helps in digestion, suppression of disease-causing bacteria and treats constipation. It also is beneficial in treating irritable bowel syndrome. It breaks down sugar into lactic acid.
A study by a Bhubaneswar-based professor Balamurugan Ramdas also revealed that Bengal or Odisha's popular breakfast Panta Bhaat, which includes fermented cooked rice, also releases the same bacteria, that fermented milk releases and so it contains short-chain fatty acids, which are responsible for improving gut health and boosting immunity.
Furthermore, curd is known to balance the gut flora, probiotics improve digestion, and the absorption of nutrition. They also help in the breakdown of food, reducing issues like bloating, gas, and constipation. The probiotics in curd can help restore the natural balance in your gut, which can soothe an upset stomach and alleviate discomfort from indigestion. A healthy gut is closely linked to a strong immune system, and the probiotics in curd help to boost gut health, which in turn can enhance immunity.

Bread is a staple across most diets, but not all loaves are made the same. In recent years, sourdough has gained a reputation for being the “healthier” bread—praised for its tangy flavour, natural fermentation, and supposed benefits for digestion. But how much of this is true? Here’s what experts and studies reveal about how sourdough compares to regular bread in terms of health and nutrition.
Unlike most commercial breads that rely on baker’s yeast for quick rising, sourdough is made using a natural starter—a mixture of flour and water that ferments over several days. This starter contains wild yeast and lactic acid bacteria, which break down carbohydrates and gluten during fermentation.
According to the Harvard T.H. Chan School of Public Health, this slow fermentation process increases the bioavailability of nutrients like folate and magnesium while producing organic acids that give sourdough its characteristic tang. In contrast, regular white or whole wheat bread undergoes a much faster process, often with added yeast, sugar, and preservatives to speed up production.
One of sourdough’s biggest advantages lies in how it affects the gut. The fermentation process partially breaks down gluten, making it easier for some people to digest compared to conventional bread.
A 2021 review published in the journal Food Microbiology found that lactic acid bacteria in sourdough can help reduce compounds called FODMAPs—a group of carbohydrates known to trigger bloating and discomfort in people with irritable bowel syndrome (IBS). This makes sourdough a potentially gentler option for sensitive stomachs, though it’s not suitable for those with celiac disease.
Another reason nutritionists often recommend sourdough is its effect on blood sugar levels. The acids produced during fermentation slow down the rate at which glucose is released into the bloodstream.
Research published in the Journal of Cereal Science noted that sourdough bread has a lower glycemic index (GI) than regular white or whole wheat bread. This means it causes a slower, more stable rise in blood sugar, something especially beneficial for people with diabetes or insulin resistance.
While both sourdough and regular bread contain similar calories and macronutrients, sourdough tends to have slightly higher levels of antioxidants and minerals because of the fermentation process. It also naturally resists mould growth, allowing it to stay fresh longer without artificial preservatives.
As per Cleveland Clinic dietitians, choosing whole-grain sourdough offers the best nutritional value, combining the fibre of whole wheat with the gut-friendly benefits of fermentation. On the other hand, refined white breads offer little fibre and are often fortified artificially.
Sourdough is not a miracle food, but it does stand out as a healthier and more digestible alternative to most commercial breads. Its fermentation process not only enhances flavour and texture but also supports gut health and stable blood sugar levels.
If you enjoy bread and want to make a more wholesome choice, opt for an artisanal or homemade sourdough made with whole grains and minimal additives. As nutrition experts often say, the real key is balance, pair your bread with fibre, protein, and healthy fats for a meal your gut (and taste buds) will thank you for.
