We all know that drinking water is good for us. If you are feeling tired, have some water. Have a dry skin? Have some water. Have a dry throat? Have some water. It is almost like water is the fix to all our issues. May be it is, but not always. So, are we sometimes drinking more water than necessary? What happens then?

Many say that there is an 8x8 rule one must follow when it comes to drinking water.

What is the 8x8 drinking water rule?

Many believe that in the 8x8 rule, eight 240ml glasses of water per day adds up to almost 2 liters. However, it is not in the guidelines in both the UK and the EU health advisory. None of them recommends this specific amount.

So, where did it origin from?

The origins of this rule seem to come from misinterpreted advice given decades ago. In 1945, a US advisory board suggested adults should consume one milliliter of fluid per calorie of food, totaling about two liters for women and 2.5 liters for men. Importantly, this included all drinks and even water-rich foods like fruits and vegetables.

A later book in 1974 recommended six to eight glasses of water daily but also noted that coffee, tea, and even beer could count towards hydration. Yet, the idea of drinking two liters of plain water daily took hold and has persisted ever since.

How Much Water Do We Really Need?

As per experts, drinking 8 glasses of water a day may be unnecessary and the research estimates that the actual requirement is around 1.5 to 1.8 liters per day. This not only includes water, but all kinds of fluids from all sources that we may consume in a day.

Also, studies show that instead of following a rigid routine, what is best is to focus on factors like temperature, physical activity and health conditions for your water intake. Those in hot and humid climate, high altitudes or pregnant or breastfeeding, and athletes may require more water. Whereas those in cooler areas, with a more sedentary lifestyle won't. However, for the average person, thirst is a more reliable guide than any fixed rule.

Science of Hydration and Dangers Of Over hydration:

Water is necessary to transport nutrients, control temperature, and keep organs functioning. We lose water through sweat, urine, and respiration, so staying hydrated is critical. However, dehydration develops only when the body loses 1-2% of its total water content.

A widespread myth is that feeling thirsty indicates that you are already severely dehydrated. Experts argue that thirst is an excellent evolutionary mechanism that ensures us drink when we need to. The body also produces hormones that aid in water conservation when necessary.

Drinking More Water Than Needed:

While drinking too much water is generally harmless, it can cause hyponatremia, a condition in which salt levels in the blood become dangerously low. This can result in brain enlargement, disorientation, convulsions, and, in extreme cases, death.

There have been reports of athletes overhydrating during endurance races, resulting in significant difficulties. Experts caution that simply following hydration myths might be dangerous, stating that thirst remains the greatest signal of when to drink.

Health officials in the United States are investigating a growing outbreak of Cyclospora, a microscopic parasite that causes the intestinal illness cyclosporiasis.

While the source of the outbreak is not yet clear, cases have been rising in northwest Ohio and southeast Michigan. The Michigan Department of Health and Human Services (MDHHS) reported on July 1 that 170 people across seven counties in Michigan had been infected as of June 30.

"Outbreaks of cyclosporiasis have been occurring across the United States and now here in Michigan. Based on the unusual number of cases we have identified in a little over a week, we anticipate additional cases of illness being reported," said Dr. Natasha Bagdasarian, the state's chief medical executive.

Earlier, the US Centers for Disease Control and Prevention (CDC) reported that 145 people, aged 5 to 86, contracted the parasite between May 1 and June 16. Twenty people were hospitalized, with infections reported across 17 states. New York recorded the highest number of cases.

New York has reported the highest number of cases, with between 31 and 80 infections, according to The Independent. Illinois and Texas have each reported between 11 and 30 cases.

Other affected states include: Alaska, Colorado, Connecticut, Florida, Georgia, Louisiana, Massachusetts, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, Wisconsin. Each of these states has reported between one and 10 cases.

What Foods Should You Avoid?

According to the CDC, cyclosporiasis outbreaks in the US have frequently been linked to imported fresh produce and to travelers returning from Cyclospora-endemic regions. However, investigators believe the current outbreak is associated with contaminated food consumed within the United States, as most patients had not traveled internationally before becoming ill.

Health officials have not advised people to avoid all fresh produce, as investigators have not yet identified the exact source of the outbreak. However, previous US outbreaks have been linked to imported fresh produce such as:

• Basil
• Cilantro
• Mesclun lettuce
• Raspberries
• Snow peas

So far, no outbreaks have been linked to commercially frozen or canned produce.

The parasite spreads through food or water contaminated with human feces and is not spread directly from person to person.

How To Prevent Cyclospora Infection

The CDC recommends following safe food handling practices to reduce the risk of infection:

• Wash your hands with soap and water before and after handling fresh fruits and vegetables.
• Wash all fruits and vegetables thoroughly under running water before eating, cutting, or cooking.
• Produce labeled "prewashed" does not need to be washed again.
• Scrub firm produce, such as melons and cucumbers, with a clean produce brush.
• Cut away any bruised or damaged areas before eating.
• Refrigerate cut, peeled, or cooked fruits and vegetables within two hours.

It also advises people traveling to tropical and subtropical regions, where Cyclospora is more common, should also be cautious. Routine chemical disinfectants used on food or water do not reliably kill the parasite.

What Is Cyclospora cayetanensis?

Cyclospora cayetanensis is a microscopic parasite that causes cyclosporiasis, a foodborne intestinal illness. People become infected by consuming contaminated food or water.

The infection commonly causes watery diarrhea and other digestive symptoms. While many cases are mild, the illness can last weeks or even months if left untreated. Doctors typically treat the infection with antibiotics.

People with weakened immune systems, including those with HIV/AIDS, cancer, or other conditions affecting immunity, are at greater risk of developing severe illness.

Symptoms of Cyclospora Infection

Symptoms usually begin about one week after consuming contaminated food or water and may include:

• Watery or explosive diarrhea
• Loss of appetite
• Bloating and gas
• Fatigue
• Low-grade fever
• Nausea
• Stomach cramps
• Vomiting.

The West Bengal government’s recent move to substitute eggs with soybean, paneer, and other vegetarian sources in Kolkata’s midday meal scheme has been met with mixed responses. Amid concern for protein deficiency in children, we took a deeper look into the eggs vs soybean debate.

Eggs Vs Soya: Which Is Better?

After the International Society for Krishna Consciousness (ISKCON) took over midday meal duties in Kolkata, it switched to an all-vegetarian diet that entailed removing eggs. The move sparked a debate about the efficacy of vegetarian sources of protein, especially plant-based ones like soybean.

Experts believe that it's not a matter of one food vs the other but understanding the distinct nutritional benefits of each.

HealthandMe spoke to Dr. Aaryin Memon, Clinical Nutritionist, Bhailal General Amin Hospital, Vadodara, about the impact of relying on soybean for protein instead of eggs.

Dr Memon says that protein is one of the key nutrients during childhood and plays a role in the growth, development of muscles, immunity, and brain function. She says that eggs and soybeans are both good sources of protein, but they have different nutritional profiles and impact on the body.

As we have always been told that eggs are the gold standard when it comes to protein for the following reasons:

• Eggs contain all nine essential amino acids in highly available forms.

• Eggs are packed with vitamin B12 and vitamin D.

• Eggs also contain choline, selenium, and healthy fats.

Additionally, eggs are important for growing children as they contribute significantly in all-round development.

The expert says, “They contain a great amount of choline, which is essential for brain development, memory, and learning.”

When it comes to vegetarian sources of protein that match the nutritional value of eggs, soybeans are one of the top on the list. It is an excellent source of protein, dietary fibre, iron, calcium, magnesium, and beneficial plant compounds including isoflavones.

Soya can also help satisfy children's nutritional requirements and is a recommended vegetarian source of protein, according to nutritionists. It is also inexpensive, readily available, and appropriate for egg-free children's diets due to dietary, religious, or cultural preferences.

But the nutritionist points out that there are differences in their nutritional profiles.

Dr Memon says, “Soybean is a good source of protein, but plant protein is less bioavailable than animal protein. Certain nutrients like vitamin B12 are not found in plant-based protein sources. Additionally, the iron found in soya does not get absorbed in the body as well as iron from animals.”

Soybeans’ comparatively weaker nutritional profile is the reason why vegetarians have to rely on a diverse range of high protein foods like pulses, dairy products, legumes, nuts and seeds, as well as foods rich in vitamin C to support iron absorption, like fruit and vegetables.

This brings us to the conclusion that school meal programmes should embrace an 'either-or' option and include eggs and well-planned vegetarian options where possible. This enables children to have the right kind of nutrition and takes into account differences in their diets.

Heartburn and bloating are common indicators of indigestion. According to the US National Institute of Health, more than one billion people worldwide suffer from heartburn and related acid reflux, while nearly 18 per cent of the global population suffers from chronic bloating weekly.

Spicy foods are commonly blamed for heartburn and bloating; however, Dr Saurabh Sethi, a Harvard-trained gastroenterologist, has debunked this myth by claiming five recurring habits that he has seen common amongst such patients in his vast years of experience.

Addressing these underlying issues may help improve symptoms before turning to additional medications, he said, in an Instagram Post.

• Not enough fiber in the diet

Topping the list is a problem that affects a large portion of adults: inadequate fiber intake.

Fiber plays a critical role in maintaining a healthy gut microbiome and supporting regular digestion.

”A fiber-depleted gut feeds the wrong microbes, leading to excess gas and bloating,” Dr. Sethi said. The daily fiber intake target for an adult should be between 25 and 38 grams, which most adults fail to meet.

• Chronic stress

The connection between mental health and digestive health is stronger than many people realize.

The gastroenterologist stated that the gut-brain axis, the communication network linking the digestive system and the brain, is real, and stress can alter gut motility, increase symptom perception, and worsen both bloating and reflux.

• Wrong use of Peppermint

Peppermint tea is a naturally caffeine-free herbal infusion made from leaves of the peppermint plant, widely enjoyed to soothe digestion and reduce bloating.

However, it can cause the opposite of treating bloating by relaxing the lower esophageal sphincter and worsen heartburn.

“You may be treating one symptom while triggering another,” said the specialist, who has performed over 1000 endoscopies.

• Lying down after the meals

Another common habit among patients with chronic heartburn is lying down shortly after meals.

The doctor explained that gravity is the best antacid, and lying down within 2 to 3 hours of eating can cause heavy acid reflux. Dr. Sethi claims that he sees this pattern in chronic heartburn patients every week.

• Eating too fast

Many people rush through meals without realizing the impact it can have on digestion. One of the biggest contributors to bloating is swallowed air, which increases significantly when people eat too quickly.

"Your stomach isn't a trash compactor," said the gastroenterologist. He also talked about how fast eaters swallow significantly more air than slow eaters.

Dr Sethi said that for people struggling with chronic heartburn and bloating, the solution may not always involve eliminating spicy foods or adding another medication.
