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.

Spices in Your Kitchen Cabinet That Are More Potent Than You Think

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

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

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

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

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

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.

Supplements vs. Culinary Use: Know the Difference

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.

Why Supplements Are More Dangerous Than Spices Used in Cooking?

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.

When to Consult A Doctor?

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.

Things to Keep In Mind

Use only culinary amounts of spices such as turmeric, ginger, and garlic.

• Shun high-dose supplement use except on orders from a licensed medical practitioner.
• If you're taking anticoagulants, insulin, or chemotherapy, caution is necessary.
• Watch for unusual symptoms, including bruising easily, feeling tired, or having abdominal pain, and tell your doctor.
• Used in small amounts, spices such as ginger, garlic, and turmeric can add flavor to your food and to your life. But abuse — particularly in the form of supplements — can cause unanticipated and potentially deadly interactions with prescription drugs.

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.

The Indian Council of Medical Research–National Institute of Nutrition (ICMR-NIN) has launched a new policy document aimed at tackling childhood obesity and promoting healthier diets and food environments for children and adolescents in India.

Released under the multi-institutional 'Let's Fix Our Food' (LFOF) consortium, which was launched in 2022, the policy comes as India faces a growing burden of obesity and diet-related non-communicable diseases (NCDs), including diabetes, hypertension, cancer and respiratory illnesses.

The document outlines evidence-based recommendations to improve food environments and encourage healthier dietary habits among children and adolescents.

"Evidence-based, multisectoral policy action is essential to create healthier food environments for children and adolescents. Collaborative initiatives such as the Let's Fix Our Food Consortium are important for addressing the growing burden of overweight, obesity and diet-related non-communicable diseases in India," said Dr. M. Srinivas, Member (Health), NITI Aayog.

What Does The Policy Recommend?

The policy outlines recommendations across several areas, including:

• Healthy school food environments
• Nutrition literacy
• Front-of-pack nutrition labelling
• Regulation of unhealthy food marketing to children
• Taxation of foods high in fat, salt and sugar (HFSS)
• Healthier dietary fats
• Salt reduction
• Low-sodium salt substitutes
• Social and behavior change communication
• Youth engagement
• Fiscal measures to promote healthier diets.

India's Growing Obesity, Malnutrition Burden

The policy highlights India's growing double burden of malnutrition.

According to the National Family Health Survey-6 (NFHS-6) fact sheets for 2023–24, the prevalence of overweight children under five has increased to 3.4%, up from 2.1% in NFHS-4 and 1.3% in the previous survey.

The survey also found that although stunting among children under five has declined to 29.3%, acute malnutrition (wasting) remains unchanged at 5.2%, and only 15% of young children receive an adequate diet.

"Malnutrition is no longer only about undernutrition. Rising obesity, driven by unhealthy diets, challenges healthy growth among children and adolescents," said Marie-Claude Desilets, Chief of Nutrition, UNICEF India.

Key Recommendations

The Let's Fix Our Food Consortium was established to generate evidence and drive policy action for healthier food environments, particularly for children and adolescents. Based on multidisciplinary research and expert consultations, the policy recommends:

Stricter Advertising Rules

• Enforce legal restrictions on marketing HFSS foods to children and adolescents.
• Ban misleading health claims and deceptive advertising across all media.

Front-of-Pack Nutrition Labels

• Introduce mandatory, easy-to-read nutrition labels on packaged foods.
• Help consumers quickly identify products high in fat, salt and sugar.

Healthier School Food Environments

• Restrict junk food in and around schools.
• Ensure affordable, healthy food options and monitor school food environments using NEAT-S.

Tax Junk Food

• Levy taxes on HFSS foods and sugar-sweetened beverages to discourage consumption.
• Use fiscal measures to make healthier foods more affordable.

Strengthen National Programs

• Integrate these measures into initiatives such as the Ayushman Bharat School Health and Wellness Programme to promote better nutrition and physical activity.

New Tools to Support Healthy Eating

The consortium also launched practical tools to help schools and adolescents make healthier food choices.

• Nutrition Environment Assessment Toolkit for Schools (NEAT-S): A framework to help schools assess and improve their food environments by promoting healthier canteens.
• Digital Literacy Modules: An interactive e-learning platform and comic books developed by ICMR-NIN to help adolescents understand food labels and reduce their intake of excess sodium and unhealthy fats.

The initiative is supported by several national and international organizations, including UNICEF India, the Global Health Advocacy Incubator (GHAI), the Public Health Foundation of India (PHFI), the World Health Organization (WHO), the Food Safety and Standards Authority of India (FSSAI), and other partners.

Global hunger declined for the third consecutive year in 2025, but an estimated 645 million people still went hungry, while rising food prices linked to the Middle East conflict threaten to slow progress, according to a new UN report.

An estimated 7.8 percent of the global population—around 645 million people—were affected by hunger in 2025, down from 8.1 percent in 2024 and 8.6 percent in 2022, according to The State of Food Security and Nutrition in the World 2026 (SOFI 2026) report released on Tuesday by five UN agencies—FAO, IFAD, UNICEF, WFP and WHO.

The figure represents 14 million fewer hungry people than in 2024 and 43 million fewer than in 2022, marking the third consecutive year of improvement.

"While we welcome the clear progress we have made in reducing hunger, a healthy diet still remains unaffordable for one in three people globally. Obesity is rising and progress on maternal and child nutrition is stalling," said WHO Director-General Dr Tedros Adhanom Ghebreyesus.

Over 2 Billion People Still Face Food Insecurity

Despite the decline in hunger, 25.8 percent of the world's population—around 2.1 billion people—experienced moderate or severe food insecurity in 2025, meaning they were forced at times to compromise on the quality or quantity of the food they consumed.

This is down from 27.1 percent in 2024 and 28.7 percent in 2020, equivalent to 86 million fewer people than in 2024 and 135 million fewer than in 2020, although levels remain above those seen before the COVID-19 pandemic.

Progress Uneven Across Regions

Africa is now home to the largest number of hungry people, with 309 million affected.

More than half (56.6 percent) of Africa's population experienced moderate or severe food insecurity in 2025, compared with:

• 20.3 percent in Asia
• 22.9 percent in Latin America and the Caribbean
• 8.7 percent in North America and Europe

Women continue to be disproportionately affected by food insecurity, although the gender gap narrowed slightly in 2025.

Middle East Conflict Could Slow Progress

The report warned that the ongoing Middle East conflict could delay global efforts to end hunger by driving up food prices through higher energy and fertilizer costs.

Depending on how long the crisis affects food inflation, 510–520 million people could still face hunger by 2030, compared with 503 million projected before the conflict, the report said.

It also noted that other risks—including extreme weather events such as El Niño in 2026 and 2027—were not included in these projections and could further worsen the outlook.

The report warned that the conflict, combined with extreme weather and declining humanitarian funding, threatens to reverse recent gains in reducing global hunger.

"This report is a stark reminder that food systems fail millions of children and families. Food, health, education and social protection must go hand in hand to protect the most vulnerable children and women from global shocks," said UNICEF Executive Director Catherine Russell.

Healthy Diet Now Costs 25% More

Nutritious food has become up to 25 percent more expensive over the past five years, leaving 2.69 billion people—nearly one in three globally—unable to afford a healthy diet.

The average global cost of a healthy diet rose to US$4.28 (PPP) per person per day in 2025, up from US$3.44 in 2021 and US$2.94 in 2017.

Dr Ghebreyesus urged governments to adopt policies that make "healthy food the easy choice," including promoting breastfeeding, front-of-pack nutrition labelling, taxing unhealthy products, and protecting children from harmful food marketing.

"Healthy diets are not a luxury—they are the foundation of health and must be within everyone's reach," he said.

Love your daily cup of coffee? The way you brew it could make a difference—not just for its taste, but also for your cholesterol levels.

A new scientific statement from the American Heart Association (AHA), published in the peer-reviewed journal Circulation, stated that for most healthy adults, drinking up to five cups of black caffeinated coffee a day (up to 400 mg of caffeine) is safe and may even benefit heart health.

However, the statement, based on a review of the latest evidence on caffeine and cardiovascular health, noted that the brewing method matters because some types of coffee contain compounds that can raise LDL, or "bad," cholesterol.

Black Coffee May Benefit Heart Health

According to the AHA, moderate consumption of black, caffeinated coffee without added sugar, cream, or flavored syrups has been linked to several cardiovascular benefits.

A review of the latest evidence found that drinking three to five 8-ounce cups of regular black coffee daily was associated with a lower risk of:

• Heart disease
• Stroke
• Heart failure
• Type 2 diabetes
• Some abnormal heart rhythms.

"Caffeine consumed in coffee is a key part of daily life for millions of people, and in our review of the most recent research, for most adults, intake of up to 400 mg of caffeine/day, the equivalent of up to five cups of caffeinated coffee per day without added sugars or fillers, is safe and does not increase cardiovascular risk," said Gregory M. Marcus, chair of the scientific statement writing group and professor of medicine at the University of California, San Francisco.

Why Brewing Method Matters

While coffee itself may support heart health, the AHA highlighted one naturally occurring compound—cafestol—that can raise LDL ("bad") cholesterol.

Cafestol is found in both caffeinated and decaffeinated coffee, but its levels depend on how the coffee is prepared.

Cafestol, associated with increased LDL cholesterol levels, is high in unfiltered coffee, including:

• French press
• Espresso
• Turkish coffee
• Boiled coffee

In contrast, paper-filtered coffee and instant coffee contain little to no cafestol, making them a better choice for people concerned about cholesterol.

Coffee And Blood Pressure

The statement also found that coffee's effect on blood pressure is complex, and they called for more studies to better understand this relationship.

Yet the findings revealed that among people with normal blood pressure, drinking one to three cups a day was associated with a higher risk of developing hypertension, while consuming more than three cups daily was linked to a lower risk.

Coffee May Lower Diabetes Risk

Although caffeine may temporarily reduce insulin sensitivity, regular consumption of black caffeinated coffee has been linked to a lower risk of Type 2 diabetes. Researchers believe this benefit is likely due to compounds in coffee other than caffeine.

Energy Drinks Are Not the Same

The AHA cautioned that the findings do not apply to energy drinks or energy shots. These products contain much higher concentrations of caffeine—around 40–69 mg per fluid ounce, roughly three to four times more than regular brewed coffee—and have been linked to high blood pressure, abnormal heart rhythms, and other cardiovascular risks, even in healthy adults under 30.

No Universal Recommendation

Marcus stressed that there is no one-size-fits-all recommendation for caffeine intake because people respond differently based on age, genetics, medications, underlying health conditions, and how quickly they metabolize caffeine.

He advised people to pay attention to how their body responds to caffeine and discuss their intake with their healthcare provider if they experience symptoms such as palpitations, anxiety, or sleep disturbances.
