Common cold is as common as its name, and while there are over the counter medicines available, people do take refuge to home-remedies. The most common remedy that people often opt for is chicken soup. Every one has their own take on cold remedies, from orange juice to zin lozenges, chicken soup to garlic capsules and more.

Colds are practically everywhere and are caused by more than 200 viruses. Our immune system has two protective mechanisms: the innate system, which removes invaders, and the adaptive system, which generates memory cells to battle known threats. Unfortunately, because cold viruses are constantly mutating, we can get them many times a year.

Because nutrition and lifestyle influence immunological health, several home remedies attempt to boost our bodies' defences. Can any of these medicines withstand scientific scrutiny?

Can These Supplements Actually Help?

If you already eat a well-balanced diet, adding extra nutrients will not instantly boost your immune system. Experts feel that supplements are only useful if you are deficient in essential vitamins or minerals such as zinc, iron, or vitamin C.

However, some studies suggest that garlic may help prevent colds. One study tracked 146 people for 12 weeks over the winter and discovered that those who took garlic supplements had significantly fewer colds (24 vs. 65 in the placebo group) and sick days (111 vs. 366). While the research is limited, it looks that garlic might help.

So, Does Vitamin C actually work?

A 2023 review found that vitamin C reduces the severity of common cold symptoms like a runny nose and sore throat by about 15%.

Vitamin C seems to work better on severe cold symptoms than mild ones.

While supplements might help, orange juice doesn’t pack enough vitamin C to make a big difference.

What About Zinc?

One review found that taking 80-92mg of zinc acetate lozenges daily within 24 hours of symptoms cut the duration of a cold by a third and reduced sneezing and coughing.

Another study found no benefit from 72mg zinc lozenges taken for five days, but researchers say dosage and duration might explain the difference.

Zinc lozenges (not tablets or food sources) seem to be most effective since they dissolve in the throat, where the virus is active.

Placebo Effect

Other home remedies which are not part of supplements are often treated for its power of placebo effect. A study on echinacea found that people who believed it helped colds experienced shorter, milder illness, even when the home remedy actually had no impact.

Same is the case with milk. There are people who believe that milk in fact increases mucus, and lead to more congestion. As a result, it worsens the cold. However, no research could prove that.

This means placebo effects work on trusted sources, it could be a doctor or even someone at your home, who may hand you over a bowl of chicken soup for your cold to get better. It works if you believe it to. Chicken soups, however, are more of a comfort food, and it makes you feel better rather than actually curing a cold.

We already know that ultraprocessed foods are linked to obesity, heart disease, and diabetes. But now, a new study published in the medical journal Thorax suggests a concerning addition to that list, lung cancer.

According to researchers, people who consume the highest amounts of ultraprocessed foods may face a 41% higher risk of being diagnosed with lung cancer, compared to those who eat the least, even when accounting for smoking and other known risk factors.

What Are Ultraprocessed Foods?

Ultraprocessed foods are industrial formulations made largely or entirely from substances not typically used in home cooking.

According to the Food and Agriculture Organization of the United Nations, these include artificial colorings, preservatives, emulsifiers, and chemically altered fats, sugars, or salts.

Common examples? Think sodas, chips, packaged soups, processed meats like chicken nuggets and cold cuts, instant noodles, diet soft drinks, and even some ice creams.

These additives enhance taste, shelf-life, and appearance, but at what cost?

What Does The Study Reveal About Food Choices and Lung Cancer Risk

Researchers behind the Thorax study analyzed data from over 100,000 adults who participated in the U.S. National Health and Nutrition Examination Survey. Each person filled out a detailed dietary questionnaire, which researchers then compared with medical records to track lung cancer diagnoses over time.

On average, people reported eating nearly three servings of ultraprocessed food a day, most commonly lunch meats and soft drinks.

Despite adjusting for smoking habits, age, sex, and other lifestyle factors, the study found a clear association between higher ultraprocessed food intake and increased lung cancer risk, particularly among people who had never smoked.

“This strongly suggests that these foods may contribute to lung cancer risk in ways beyond just smoking,” said Dr. David Katz, a specialist in preventive and lifestyle medicine and founder of the nonprofit True Health Initiative, as reported by CNN. Though not involved in the study, Katz called the findings “concerning and credible.”

Why Would Food Be Linked to Lung Cancer?

Experts believe multiple mechanisms could be behind the link.

“Industrial processing alters the food matrix,” the study authors explained, “which affects how nutrients are absorbed and may produce harmful contaminants.”

One such contaminant is acrolein. It is a toxic compound found not only in cigarette smoke, but also produced when cooking oils or fats are heated to high temperatures.

The U.S. Centers for Disease Control and Prevention (CDC) lists acrolein as a substance that can inflame and damage lung tissue.

Packaging may also be a problem. Plastics and synthetic materials used in food storage can leach chemicals, some of which are known or suspected carcinogens.

Add to that the fact that ultraprocessed foods are often low in omega-3 fatty acids, said Dr. Tom Brenna, professor of nutrition and chemistry at the University of Texas at Austin, as reported by CNN.

“Omega-3s spoil easily, so manufacturers tend to remove them to increase shelf life,” he explained. That’s unfortunate, because omega-3s help reduce inflammation, a key process in cancer development.

Smoking Isn’t the Only Risk Factor

Lung cancer remains one of the most commonly diagnosed cancers globally, with 2.4 million new cases in 2022, according to the World Health Organization. While smoking remains the leading risk factor, experts now believe diet and environmental exposures also play a role.

Dr. Fang Fang Zhang, a professor at Tufts University’s Friedman School of Nutrition Science and Policy, as reported by CNN, noted that while the study adjusted for smoking, the adjustment may not have been thorough enough. “Smoking needs to be measured more precisely, by cigarettes per day or years of exposure,” she said. Still, she found the link stronger in non-smokers, which makes the data all the more compelling.

What You Can Do: Eat More Whole Foods

The takeaway? While more research is needed to understand the exact biological mechanisms at play, the connection between ultraprocessed foods and cancer risk can no longer be ignored.

According to Dr. Katz, the solution lies in going back to basics. “Health and diet quality improve when people eat mostly whole, unprocessed foods,” he said, including vegetables, fruits, beans, whole grains, nuts, seeds, and other plant-based ingredients.

Dr. Zhang agrees. “Avoid foods with long ingredient lists full of unfamiliar chemicals,” she advised. “Focus on meals made from whole or minimally processed ingredients whenever possible.”

Fish oil is a star supplement loaded with omega-3 fatty acids like EPA and DHA. It offers a spectrum of vital benefits for women’s health. These extend beyond general well-being to support heart, brain and joint function, especially in areas of concern specific to women.

Fish oil, rich in omega-3s, addresses unique needs across all stages of a woman’s life. From adolescence through motherhood to menopause, fish oil supports cardiovascular, hormonal, mental and reproductive health.

A Boost for the Heart

Fish oil plays a major role in promoting heart health. According to Dr Mohit Bhatia, it helps lower triglyceride levels, a risk factor for cardiovascular disease, and improves blood flow, making it essential for proper cardiovascular function. He adds that it also slows the progression of cardiovascular disease.

Karan Khurana, a health expert at WishNew Wellness, concurs, saying that omega-3s in fish oil reduce triglycerides, lower blood pressure, and decrease arterial inflammation. This is particularly vital for post-menopausal women, who face a greater risk of heart disease. Regular consumption of fish oil, he says, can even lower the risk of heart attacks and strokes.

Hormones, Menstrual Cycles and PMS

Women facing bloating, mood swings or cramps may find some relief with fish oil. Dr Bhatia says that some evidence-based research suggests fish oil can help alleviate PMS and menstrual pain, thanks to its anti-inflammatory properties.

Khurana elaborates that omega-3s may regulate menstrual cycles and reduce cramps by lowering prostaglandin levels, which contribute to pain and inflammation. He adds that fish oil can ease common PMS symptoms such as bloating and breast tenderness.

Pregnancy, Postpartum and a Baby’s Brain

The benefits of fish oil carry into pregnancy too. Dr Bhatia points out the importance of DHA during this stage, saying it is vital for healthy foetal brain and eye development. It may also reduce the risk of preterm birth and help alleviate postpartum depression.

Khurana backs this up, pointing out that fish oil supplementation not only supports cognitive function in babies but also helps mothers manage postpartum depression. It plays a role in maintaining the mother’s brain health during and after pregnancy.

Bones, Joints and the Menopause Years

Post-menopause, bone health becomes a serious concern for many women. Dr Bhatia says that the anti-inflammatory properties of fish oil can contribute to bone health, potentially reducing the risk of osteoporosis.

Khurana adds that omega-3s enhance calcium absorption and support bone density. Fish oil, he explains, helps reduce inflammation linked to joint pain, promoting stronger bones and better mobility for older women.

Better Moods and Sharper Minds

Women are more likely than men to experience anxiety and depression, and fish oil might just help. Dr Bhatia explains that these fatty acids play a role in elevating mood and supporting brain function, potentially mitigating cognitive decline.

Khurana agrees, saying omega-3s support cognitive health and reduce the risk of dementia later in life. Fish oil, he says, may alleviate symptoms of depression and anxiety, contributing to overall mental well-being.

Your Skin Will Thank You Too

Dr Bhatia does not touch on it, but Khurana dives into skin benefits. He says that fish oil improves hydration, reduces wrinkles, and protects against UV damage. Its anti-inflammatory effects can ease conditions like eczema, making skin look and feel healthier.

Final Thoughts Before You Pop That Capsule

Dr Bhatia emphasises that while fish oil is a powerful supplement, it should complement a balanced diet and healthy lifestyle. He strongly recommends consulting a healthcare professional before starting, especially for those on medication or with existing conditions.

Khurana suggests aiming for 250–500 mg of combined EPA and DHA daily, either through fatty fish like salmon or through supplements. Fish oil, he concludes, is a holistic powerhouse that can help women thrive at every stage of life.

Allergies are more common than ever with nearly 6% of adults and children in the US have some form of food allergy, and that number continues to rise. Whether it’s a peanut reaction, seasonal sneezing, or unexplained flare-ups after certain meals, allergies are increasingly linked to the immune system’s overreaction. And here’s where it gets interesting, your diet might be the missing link—not just in managing symptoms, but in preventing them in the first place.

The mainstream response to allergies often begins and ends with antihistamines but according to certified dietitian Lavleen Kaur, healing starts from within, “Allergies—whether triggered by food, weather changes, or environmental factors—are signs of an overactive immune system. True healing begins from within. Building natural immunity through nutrition is a long-term, sustainable approach that not only helps prevent allergic flare-ups but also strengthens overall health.”

Expert dietician reveals how your food and lifestyle choices can shape your immune response—and how a few shifts could help you reduce allergic reactivity naturally.

Immune System Starts in the Gut

Roughly 70% of your immune system lives in your gut. This isn’t just an interesting stat—it’s the reason nutrition plays such a central role in how your body handles allergens. A gut that’s inflamed, leaky, or dominated by bad bacteria is more likely to misfire, reacting to harmless proteins in food or the environment.

Kaur emphasizes the importance of nurturing this digestive-immune connection: “When the digestive system is strong, the immune system becomes less reactive. That’s why I often say, ‘Immunity begins at home’—not through expensive supplements, but through simple, consistent habits rooted in traditional wisdom.”

Start Your Day with Immunity-Boosting Rituals

Forget the hype around complicated health tonics. According to Kaur, the day should start with an old-school combination that’s surprisingly effective: one fig, two dates, and 3–4 black raisins, soaked overnight. “This combination is rich in iron, helps build stamina, and keeps oxygen flowing efficiently in the body,” she says.

Follow that up with probiotic-rich foods like curd, fermented kanji, or buttermilk. These naturally populate your gut with beneficial bacteria, improve digestion, and enhance immune balance.

Hydration is another non-negotiable. “Pale-yellow urine is a sign you’re well-hydrated,” says Kaur. She recommends rotating plain water with coconut water, herbal teas, and turmeric-ginger infusions—especially during allergy season, when respiratory health is easily compromised.

Eat with the Seasons, Not the Supermarket Shelf

There’s a reason your grandmother swore by seasonal eating. Fresh, in-season produce isn’t just better for the planet—it’s better for your immune system. Kaur urges people to “fill your plate with a rainbow of seasonal fruits and vegetables, especially those high in vitamin C like amla, guava, oranges, and bell peppers.”

Another group of nutrients to focus on? Quercetin and omega-3 fatty acids. Quercetin—a powerful antioxidant found in apples and onions—helps modulate the body’s histamine response, meaning fewer flare-ups. Omega-3s from flaxseeds, walnuts, and chia seeds work at the cellular level to reduce inflammation and balance immunity.

Gut Rituals that Support Allergy Relief

Beyond meals, Kaur recommends ancient digestive practices that keep the gut calm and efficient. After meals, chew a small amount of fennel seeds, cardamom, or clove with jaggery. This supports digestion and prevents the post-meal sluggishness that can signal immune stress.

At bedtime, her go-to ritual is a glass of warm turmeric milk. Turmeric is anti-inflammatory, and combining it with milk (or a plant-based alternative) enhances absorption. This simple step not only improves sleep but supports overnight cellular repair and immune regeneration.

Identify Your Real Triggers

What derails your immunity faster than pollen season? Ultra-processed foods. Refined sugar, deep-fried snacks, chemical additives, and preservative-laden packages are well-known immune suppressors. These foods also disrupt gut flora and increase inflammation, making your system more reactive.

Some people may benefit from limiting gluten or dairy, especially if allergies persist despite clean eating but Kaur cautions that elimination should always be done under guidance. “Removing a food group without support can lead to deficiencies. The goal is to reduce inflammation—not create new problems.”

Ancient Ayurvedic Ways To Relive Allergy

Modern medicine isn’t the only tool available for allergy relief. Kaur encourages integrating Ayurvedic practices like:

• Udvartan (herbal dry massage) for detoxifying the skin
• Nasya therapy (medicated nasal drops) for clearing the sinuses and balancing the mind
• Shirodhara (streaming warm oil over the forehead) to regulate nervous system sensitivity

These therapies support the body's natural detox processes and promote systemic balance—especially helpful for those with chronic skin, respiratory, or seasonal allergies.

If you’re looking for a magic pill or a shortcut, nutrition-led immunity might disappoint you. But if you’re after something sustainable, preventive, and empowering, this approach could change your life.

Building a stronger immune system isn’t about perfection. It’s about consistency. Kaur puts it simply: “When the body is nurtured consistently through nutrition and lifestyle, it becomes less reactive, more resilient, and deeply aligned with nature.”

In a world overflowing with medications, allergy shots, and crisis responses, the anti-allergy diet offers a grounded, proactive path—one meal, one habit, one day at a time.

Allergies don’t have to control your life. By rethinking your plate, daily rituals, and how you support your gut, you can create an environment where your immune system works with you—not against you. Nutrition won’t replace your EpiPen, but it might help you reach for it less often and that’s worth chewing on.
