A new global analysis has put a number on something researchers have long suspected: a significant share of the world's cancers begin with an infection.
The study, from the World Health Organization's cancer agency (the International Agency for Research on Cancer), published in The Lancet Oncology, estimates that about 2.3 million new cancer cases worldwide in 2024 — roughly 1 in 8 of all cases — were linked to infections with viruses, bacteria, or parasites. The researchers say many of these could have been prevented with tools that already exist, such as vaccines, screening, and treatment of the infections themselves.
The Five Infections Behind Most of These Cases
The analysis looked at 12 infectious agents classified as definite carcinogens. Just five of them accounted for more than 2.2 million of the estimated 2.3 million infection-linked cases:
Helicobacter pylori (H. pylori) — about 760,000 cases, mostly stomach cancers.
Human papillomavirus (HPV) — about 750,000 cases, led by cervical cancer but also including some anal and head-and-neck cancers. All cervical cancer cases in the analysis were attributed to HPV.
Hepatitis B — about 360,000 cases, mostly liver cancers.
Epstein-Barr virus (EBV) — about 260,000 cases, including nasopharyngeal cancer, Hodgkin's lymphoma, and some gastric cancers.
Hepatitis C — about 160,000 cases, mostly liver cancers.
Together, H. pylori and HPV alone were behind roughly 1.5 million cases in 2024.
How Can an Infection Lead to Cancer?
The idea is not that a single infection immediately causes cancer. Rather, certain long-term infections can quietly damage cells over many years, and in some people that slow, cumulative damage eventually tips into cancer. This is also why prevention works on a long timeline: treating or vaccinating against the infection can stop the process long before it reaches that point. As the study's senior author put it, "we can intervene before it gets anywhere near cancer."
The Encouraging Part: Much of This Is Preventable
Unlike many cancer risk factors, these infections have known, existing countermeasures:
Vaccines — HPV and hepatitis B vaccines are among the most effective tools we have, and they work best when given before exposure.
Testing and treatment — H. pylori can be detected with simple tests and treated with antibiotics; chronic hepatitis B and C have antiviral treatments that lower liver-cancer risk.
Screening — Cervical screening catches HPV-related changes early, when they are most treatable.
The researchers note that the burden falls heaviest where these prevention tools reach the fewest people — which makes awareness itself part of the solution.
Frequently Asked Questions
Q: If I get one of these infections, will I get cancer?
No. Most infections never lead to cancer — the study estimates population-level shares, not individual risk. Cancer develops in some people after years of persistent infection. If you have symptoms or concerns, talk to a clinician rather than trying to self-assess your risk.
Q: What should I ask my doctor about?
HPV vaccination, hepatitis B vaccination, and testing or treatment for H. pylori if you have persistent stomach symptoms are the topics researchers highlight most. But which of these apply to you depends on your age, history, and local health guidance — a clinician can advise on what fits your situation.
Q: Do the usual healthy habits still matter?
Yes. Infection prevention adds to established steps — not smoking, a balanced diet, regular physical activity, and recommended cancer screenings — rather than replacing them.
The Bottom Line
About 1 in 8 cancers in 2024 had a preventable beginning: an infection we already know how to stop. Vaccines, screening, and straightforward treatment exist for the biggest culprits. The gap is not knowledge — it is making sure those tools reach everyone.

Dengue is one of the fastest-growing mosquito-borne threats in the world. The World Health Organization estimates 100 to 400 million infections every year, and cases have been rising sharply across tropical and subtropical regions in recent years. There is no specific cure for dengue, which is exactly why prevention matters so much — no matter where you live. Here is what you can do to protect yourself and your family.
What Is Dengue, and Why Is It Spreading?
Dengue is a viral illness spread by the bite of infected Aedes mosquitoes, mainly Aedes aegypti. Unlike the mosquitoes that spread malaria, Aedes mosquitoes bite mostly during the daytime, especially in the early morning and late afternoon.
These mosquitoes breed in clean, stagnant water — flower pots, discarded tires, buckets, clogged drains, and even bottle caps. It only takes a small amount of standing water for them to multiply, which is why dengue spikes during and after the rainy season. Dengue is now a risk in more than 100 countries, and travel, urbanization, and warming climates are steadily expanding the mosquito's range.
10 Practical Ways to Prevent Dengue
1. Empty standing water every week. Check flowerpot saucers, buckets, tires, and any containers around your home. Scrub them too, because mosquito eggs can stick to the sides.
2. Cover all water containers. Tanks, drums, and jars should be tightly covered or fitted with mesh so mosquitoes cannot get in to lay eggs.
3. Sleep under a mosquito net. A properly tucked-in net is one of the most reliable barriers, especially for children and anyone resting during the day.
4. Fit window and door screens. Mesh screens on windows and doors keep mosquitoes out while letting air in. Repair any tears promptly.
5. Use a proven mosquito repellent. Repellents containing DEET, picaridin, or oil of lemon eucalyptus are recommended by health authorities. Follow the label instructions, especially for children.
6. Wear protective clothing. Long sleeves, long trousers, and light-colored clothing make it harder for mosquitoes to reach your skin during peak biting hours.
7. Use coils, vaporizers, or sprays indoors. These can reduce mosquitoes inside the home. Use them in ventilated rooms and keep them away from children and food.
8. Keep your surroundings clean. Clear clogged drains, trim overgrown bushes, and dispose of trash that can collect rainwater. Dengue control is a neighborhood effort.
9. Protect children at school and play. Apply repellent before they leave home, and make sure classrooms and play areas do not have open water containers nearby.
10. Join community clean-up drives. One untended rooftop or empty plot can breed mosquitoes for an entire street. Coordinated weekly clean-ups are one of the most powerful tools a neighborhood has — public health experts note that community engagement greatly strengthens dengue control.
Warning Signs to Take Seriously
Dengue often starts with a sudden high fever, severe headache, pain behind the eyes, and muscle or joint pain. Most people recover with rest, fluids, and medical guidance — but some cases can become serious.
Seek medical care promptly if a fever is accompanied by severe abdominal pain, persistent vomiting, bleeding gums, unusual tiredness, or restlessness. Do not self-medicate with aspirin or ibuprofen during a suspected dengue fever; a doctor can advise the safest approach. If in doubt, see a healthcare professional early rather than waiting.
Frequently Asked Questions
Can dengue spread directly from person to person?
No — not through ordinary contact. Dengue spreads through the bite of an infected Aedes mosquito; you cannot catch it from touching or being near someone who has it. (Very rarely, transmission through blood transfusion or from mother to baby has been recorded.)
When are Aedes mosquitoes most active?
They bite mainly during the day, with peaks in the early morning and late afternoon. That is why daytime protection matters as much as nighttime nets.
Is there a dengue vaccine?
Dengue vaccines exist in some countries but are not widely available everywhere and are recommended only for specific groups. Prevention through mosquito control remains the main strategy for most people.
Does getting dengue once make you immune?
There are four types of the dengue virus. Recovery from one type gives immunity to that type only, and a second infection with a different type can be more serious — another reason prevention matters.
When should I see a doctor?
If you develop a sudden high fever with any of the symptoms above, especially during dengue season, consult a healthcare professional promptly. Early medical attention leads to better outcomes.
Dengue season will pass, but the habits above protect your family year after year. Start with your own home this week — empty that saucer, cover that tank, fix that screen. Small actions, done by many households together, are what actually stop an outbreak.

Short answer: Excess belly fat — especially deep visceral fat around organs — is linked to higher risk of heart disease, type 2 diabetes, and metabolic syndrome. You can't target it directly with ab exercises; it shrinks through overall fat loss: diet quality, exercise, sleep, and stress management.
Why belly fat matters more
Not all fat is equal. Subcutaneous fat (under the skin) is relatively harmless; visceral fat (around organs) is metabolically active and linked to insulin resistance and inflammation. Waist circumference is a useful proxy — generally, risk rises above ~102 cm (40 in) for men and ~88 cm (35 in) for women, though targets vary by ethnicity.
The spot-reduction myth
Crunches and ab exercises strengthen abdominal muscles but don't burn the fat covering them. Fat loss happens body-wide through sustained calorie balance — no exercise, cream, or wrap targets one area.
7 evidence-based strategies
Eat mostly whole foods: Vegetables, legumes, whole grains, lean proteins. Cut sugary drinks first — they're strongly linked to visceral fat.
Watch alcohol: Excess alcohol is particularly linked to abdominal fat ("beer belly" is real).
Move daily + strength train: Cardio burns calories; resistance training preserves muscle during fat loss. Both matter.
Sleep 7–9 hours: Short sleep is consistently linked to more visceral fat.
Manage stress: Chronically high cortisol is associated with abdominal fat storage.
Eat enough protein: Supports fullness and muscle maintenance during fat loss.
Be patient: Sustainable loss is ~0.5 kg/week. Crash diets cause rebound.
When to talk to a doctor: If you have a large waist circumference plus high blood pressure, blood sugar, or cholesterol, ask about metabolic syndrome screening.
Frequently Asked Questions
Q: What causes belly fat?
A: Overall calorie surplus over time, sugary drinks, excess alcohol, poor sleep, chronic stress, and inactivity. Genetics influence where you store fat, but lifestyle drives the amount.
Q: Do ab exercises burn belly fat?
A: No — this is the spot-reduction myth. Ab exercises build muscle underneath the fat. Fat loss requires overall calorie balance through diet and full-body activity.
Q: How long does it take to lose belly fat?
A: Visceral fat often responds relatively early to lifestyle change — many people see waist reductions within weeks of consistent diet and exercise. But sustainable change takes months, not days.
Q: Are "fat-burning" teas or supplements effective?
A: No supplement meaningfully burns belly fat. Most are unproven, and some are unsafe. Save your money for good food and good shoes.

Short answer: Peppermint tea is a pleasant, caffeine-free drink that may soothe mild digestive discomfort for some people. The stronger evidence for gut benefits comes from concentrated peppermint oil capsules (used for IBS in trials) — not the tea itself. It's not a treatment for any disease.
What it may help with
Mild digestive discomfort: The menthol in peppermint relaxes digestive tract muscles. Many people find a warm cup soothing after heavy meals — though this is traditional use more than proven medicine.
A caffeine-free alternative: A flavorful evening drink without caffeine or calories.
Nausea: Some people find the aroma settling, but evidence is limited.
What it won't do
Cure acne, heal skin irritation, treat bowel disorders, or grow hair. Those claims have no scientific basis.
Who should be careful
Acid reflux/GERD: Peppermint relaxes the esophageal sphincter and can worsen heartburn and reflux. If you have GERD, skip it.
Pregnancy: Moderate amounts as tea are generally considered fine, but concentrated peppermint oil supplements should be avoided unless your doctor approves.
How to enjoy it
Steep 1 tablespoon of dried peppermint leaves (or a tea bag) in hot water for 5–10 minutes. Drink plain or with a little honey.
Frequently Asked Questions
Q: Is peppermint tea good for IBS?
A: The clinical evidence for IBS involves enteric-coated peppermint oil capsules, not tea. The tea is much more dilute — it may feel soothing, but don't expect therapeutic effects.
Q: Does peppermint tea help with bloating?
A: It may ease the sensation of fullness for some people after meals, likely through muscle relaxation in the gut. Evidence is mostly anecdotal.
Q: Can I drink peppermint tea every day?
A: Yes, 1–3 cups daily is fine for most people — unless you have acid reflux, which peppermint can worsen.
Q: Does peppermint tea have caffeine?
A: No — it's naturally caffeine-free, making it a good evening drink.

Short answer: The nutrition advice with the strongest evidence is refreshingly simple: eat mostly whole foods, get enough protein and fiber, limit sugary drinks and ultra-processed foods, and be consistent. Here are 10 practical tips grounded in research.
1. Eat protein at breakfast
Higher-protein breakfasts improve fullness and reduce later snacking in trials. Eggs, yogurt, beans, or nuts all work — not just meat.
2. Make fiber a priority
Most people get half the recommended fiber. Vegetables, fruits, legumes, and whole grains support digestion, gut bacteria, cholesterol, and blood sugar.
3. Cut sugary drinks first
Sodas, sweetened teas, and fancy coffees are the single biggest source of added sugar for many people. Replacing them with water is one of the highest-impact changes you can make.
4. Choose whole grains over refined
Brown rice, oats, whole-wheat bread, and quinoa retain fiber and nutrients lost in refined versions.
5. Don't fear healthy fats
Olive oil, nuts, avocados, and fatty fish support heart health. It's excess calories and trans fats to watch — not fat itself.
6. Eat a rainbow of produce
Different colors mean different phytonutrients. Aim for variety across the week rather than fixating on one "superfood."
7. Read labels, especially sugar
Sugar hides under 60+ names. Check the "added sugars" line and ingredient lists — particularly in cereals, yogurts, and sauces.
8. Cook more at home
Home cooking is consistently linked to better diet quality — you control ingredients, portions, and cooking fats.
9. Eat mindfully
Slower eating and fewer screens at meals help you recognize fullness. It sounds trivial; trials show it measurably reduces intake.
10. Be consistent, not perfect
One indulgent meal doesn't matter; patterns do. The best diet is the healthy one you can actually maintain for years.
Frequently Asked Questions
Q: What's the single most important nutrition change?
A: For most people: cut sugary drinks and eat more vegetables. Those two changes alone transform diet quality dramatically.
Q: Is breakfast really the most important meal?
A: The evidence is mixed — what matters more is overall diet quality and not overeating later. If breakfast helps you eat better through the day, keep it; if you practice time-restricted eating successfully, that's fine too.
Q: Are eggs healthy or not?
A: For most people, eggs are nutritious — good protein, vitamins, and affordable. Dietary cholesterol affects blood cholesterol less than once thought; saturated fat matters more. People with specific conditions should follow their doctor's advice.
Q: How do I know if a "nutrition tip" online is trustworthy?
A: Be skeptical of tips that promise dramatic results, demonize entire food groups, cite a single guru instead of research, or sell you the solution. Reliable advice is usually boring: vegetables, fiber, moderation, consistency.

Short answer: Avocados are uniquely nutritious — rich in heart-healthy monounsaturated fats, potassium (more than a banana), fiber, folate, and lutein. They're calorie-dense (~240 per avocado), so a third to half daily is the sweet spot for most people.
1. Rich in heart-healthy monounsaturated fats
About 75% of avocado's fat is monounsaturated (oleic acid, like olive oil) — the fat type most consistently linked to better cholesterol profiles.
2. Excellent source of potassium
One avocado has roughly 700–975 mg of potassium, supporting healthy blood pressure as part of a balanced diet.
3. High in fiber
~10g fiber per avocado — supporting digestion, gut bacteria, and satiety.
4. Contains lutein for eye health
Avocados are one of the richer fruit sources of lutein and zeaxanthin, antioxidants linked to long-term eye health.
5. Supports nutrient absorption
The fats in avocado significantly boost absorption of fat-soluble vitamins (A, D, E, K) and carotenoids from the vegetables you eat with it — a great reason to add it to salads.
6. Folate-rich
Good folate content supports cell function — relevant for everyone, and especially important in pregnancy (alongside, not replacing, prenatal care).
7. May support healthy cholesterol
Trials where avocados replaced other fats show modest improvements in LDL cholesterol.
8. Satisfying and versatile
The fat-fiber combo keeps you full. Use in salads, on toast, in smoothies — or as a butter/mayo swap.
Portion reality check: A whole medium avocado has ~240 calories. Enjoy a third to half daily rather than multiple whole avocados, especially if managing weight.
Frequently Asked Questions
Q: Is it OK to eat avocado every day?
A: Yes — a third to half an avocado daily fits well into a healthy diet. Just account for the calories if weight is a concern.
Q: Are avocados good for weight loss?
A: They can help indirectly — their fat and fiber are very satiating, which may reduce overall eating. But they're calorie-dense, so portions matter.
Q: What's the healthiest way to eat avocado?
A: Fresh, with minimal additions — on whole-grain toast, in salads (where its fat boosts vegetable nutrient absorption), or in smoothies. Skip preparations loaded with cheese, bacon, or deep-frying.
Q: How do I know when an avocado is ripe?
A: It yields gently to palm pressure (don't squeeze with fingertips). Buy firm ones to ripen at home; speed ripening in a paper bag with a banana.

1. Rich in heart-healthy monounsaturated fats
About 75% of avocado's fat is monounsaturated (oleic acid, like olive oil) — the fat type most consistently linked to better cholesterol profiles.
2. Excellent source of potassium
One avocado has roughly 700–975 mg of potassium, supporting healthy blood pressure as part of a balanced diet.
3. High in fiber
~10g fiber per avocado — supporting digestion, gut bacteria, and satiety.
4. Contains lutein for eye health
Avocados are one of the richer fruit sources of lutein and zeaxanthin, antioxidants linked to long-term eye health.
5. Supports nutrient absorption
The fats in avocado significantly boost absorption of fat-soluble vitamins (A, D, E, K) and carotenoids from the vegetables you eat with it — a great reason to add it to salads.
6. Folate-rich
Good folate content supports cell function — relevant for everyone, and especially important in pregnancy (alongside, not replacing, prenatal care).
7. May support healthy cholesterol
Trials where avocados replaced other fats show modest improvements in LDL cholesterol.
8. Satisfying and versatile
The fat-fiber combo keeps you full. Use in salads, on toast, in smoothies — or as a butter/mayo swap.
Portion reality check: A whole medium avocado has ~240 calories. Enjoy a third to half daily rather than multiple whole avocados, especially if managing weight.
Frequently Asked Questions
Q: Is it OK to eat avocado every day?
A: Yes — a third to half an avocado daily fits well into a healthy diet. Just account for the calories if weight is a concern.
Q: Are avocados good for weight loss?
A: They can help indirectly — their fat and fiber are very satiating, which may reduce overall eating. But they're calorie-dense, so portions matter.
Q: What's the healthiest way to eat avocado?
A: Fresh, with minimal additions — on whole-grain toast, in salads (where its fat boosts vegetable nutrient absorption), or in smoothies. Skip preparations loaded with cheese, bacon, or deep-frying.
Q: How do I know when an avocado is ripe?
A: It yields gently to palm pressure (don't squeeze with fingertips). Buy firm ones to ripen at home; speed ripening in a paper bag with a banana.

Short answer: Most healthy adults need roughly 2–3 liters of total water daily (from drinks and food), but needs vary with climate, activity, and diet. Pale-yellow urine is a better guide than any fixed rule — and no, timed glasses of water don't prevent strokes or heart attacks.
Why hydration matters
Water regulates body temperature, transports nutrients, lubricates joints, and helps kidneys filter waste. Even mild dehydration can cause headaches, fatigue, and poorer concentration.
How much do you actually need?
There's no magic "8 glasses" rule — it was never based on strong science.
A practical target: enough that your urine is pale yellow most of the day.
You need more in hot weather, during exercise, when ill (fever/vomiting), and during breastfeeding.
About 20% of water typically comes from food (fruits, vegetables, soups).
Debunking viral water myths
❌ "Water before bed prevents strokes/heart attacks" — no evidence whatsoever.
❌ "Water before a shower prevents high blood pressure" — no evidence.
❌ "Drink 2 glasses on waking to activate organs" — your organs activate fine on their own; morning water is pleasant but not medicinal.
✅ "Water supports kidney function and may reduce kidney stone risk" — this one is true; good hydration dilutes urine.
Practical hydration tips
Keep water visible and nearby — you'll drink more.
Drink a glass with each meal.
Before/during/after exercise, drink to thirst plus a bit more.
In heat or illness, increase intake deliberately.
Water, sparkling water, and unsweetened tea all count. Sugary drinks don't hydrate as well per calorie.
Can you drink too much?
Yes — overhydration (hyponatremia) is rare but real, mostly in endurance athletes drinking excessive water. For daily life, drinking to thirst plus normal habits is safe.
Frequently Asked Questions
Q: How do I know if I'm dehydrated?
A: Dark yellow urine, thirst, headache, fatigue, and dizziness are common signs. Pale-yellow urine generally means you're well hydrated.
Q: Does coffee dehydrate you?
A: No — this is a myth. Coffee and tea contribute to daily fluid intake. Water should still be your main drink, but caffeinated beverages count.
Q: Is it bad to drink water during meals?
A: No. This is another myth — water with meals doesn't meaningfully impair digestion for healthy people.
Q: Should I force myself to drink 8 glasses a day?
A: No need to force it. Drink regularly through the day, more when active or hot, and use urine color as your guide. Thirst is a reasonable signal for most healthy adults.
