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.

Soup debate between chicken and tomato may have come to an end, with a dietitian telling us which one is the healthier option. For many Americans, January is the National Soup Month, which means they go back to their comfort and easy to make food like soup. With the surge in flu activity in the US, people are consuming soup to get relief. Amid all this, Vandana Sheth, a plant-based dietitian and a diabetes expert tells Fox News the better option. The California-based dietitian says that both soups could be comforting. However, she points out, the nutrition profiles could vary based on the preparation.

Chicken Soup Vs Tomato Soup

Soup's nutrition profile runs through a spectrum of healthy to fatty and caloric. "Choose versions with no added sugars, minimal saturated fat and lower sodium to keep them healthy. When able, enjoy homemade or minimally processed options with fresh vegetables, lean protein and other fiber-rich options," she said.

What Is In A Chicken Soup?

Michelle Routhenstein, a New York-based cardiologist, as reported by Fox News, said a standard serving size of chicken noodle soup, which is around one cup, usually contains somewhere around 100 to 150 calories, with 6 to 10 grams of protein, and 500 to more than 1500 milligrams of sodium.

However, Routhenstein also says that homemade chicken soup could also provide lean protein, B vitamins, and immune supporting zinc. There have been studies that show that chicken soup have eased many from their cold symptoms, like nasal congestion and anti-inflammatory effects. However, not all chicken soups are safe. Commercially prepared soups may have a higher level in sodium, which could have a negative impact on blood pressure.

What Should One Keep In Mind?

When buying chicken soup, one should always check labels for its sodium content and ensure it must be under 500 milligrams per servings. Sheth also suggests looking out for added sugars and flavors. Sheth also said if the soup is made with lean chicken, vegetables and has a light broth, it can by more nutrient rich. She also recommends to avoid cream-based broth, which could be higher in saturated fat.

What Is In A Tomato Soup?

Tomato soups have a completely different nutrition profile. "Per 1 cup serving, you will get 70–150 calories depending on [whether] it's broth-based or cream-based, lycopene and vitamins A and C, which can help support eye health and immunity," Sheth said. The sodium content could be lower than in chicken soup, somewhere between 400 to 900 milligrams, especially in canned versions.

Sheth said that when compared to chicken soup, tomato soup trails on protein scale. While Routhenstein highlighted lycopene, as one of the biggest benefits of tomato soup. It is an antioxidant that "may help with reducing inflammation, heart disease and immune health".

"Lycopene has also been studied for its benefit [in reducing the] risk of prostate cancer. Tomato soup is also rich in vitamin C and potassium, which also protect heart and immune health," she added.

Which Soup Is Better?

Routhenstein says for her, it is tomato soup, because of antioxidant content. However, when it comes to protein and keeping you full, Sheth says chicken soup is a better option.

A key ingredient found in a common breakfast food may play an important role in supporting heart health and keeping blood sugar levels steady. Fibre is an essential part of a balanced diet, and the NHS recommends that adults aim for at least 30g of fibre each day. Despite this, many people still fall short of the daily target, often without realising the long-term impact on their health.

Why Fibre Matters For Heart And Blood Sugar Health

Fibre is not a single substance. It exists in two main forms, and each affects the body in a different way. Insoluble fibre does not dissolve during digestion. Instead, it passes through the gut largely unchanged, adding bulk to stools and helping the bowels move regularly. This can lower the risk of constipation and reduce the chances of developing intestinal blockages.

How Soluble Fibre Helps Control Blood Sugar Levels

Soluble fibre behaves differently. When it comes into contact with water in the digestive system, it forms a gel-like substance. This slows the digestion and absorption of carbohydrates, helping to prevent sudden rises in blood sugar after meals. Because of this effect, soluble fibre can be particularly useful for people managing blood sugar conditions, including diabetes.

What Makes Beta-Glucan Especially Good For The Heart?

Beta-glucans are a specific type of soluble fibre that have attracted attention for their heart-protective benefits. According to the British Heart Foundation, beta-glucan is naturally present in all porridge oats and wholegrains. A standard 40g serving of porridge oats contains around 2g of beta-glucan, making it an easy addition to a heart-friendly diet.

Research suggests that beta-glucan may help improve blood sugar control over time. Studies have found that consuming up to 3.5g of beta-glucan daily can lower blood sugar levels and support better long-term glucose management in people with type 2 diabetes. A higher intake of beta-glucan has also been linked to a reduced risk of developing type 2 diabetes, likely due to its ability to slow sugar absorption.

Beta-Glucan And Its Link To Lower Cholesterol

Another study has highlighted the connection between regular beta-glucan intake and improved heart health. The findings showed that eating just 3g of beta-glucan each day for eight weeks led to a noticeable reduction in cholesterol levels. High cholesterol is a well-known risk factor for heart disease, so even small daily amounts of beta-glucan may offer meaningful benefits.

Sources Of Beta-Glucan

Beta-glucan is found in a wide range of natural foods, including:

• Oats
• Rye
• Shiitake mushrooms
• Peas
• Seaweed
• Yeast
• Reishi mushrooms
• Apples
• Algae
• Barley
• Wheat

Including a variety of these foods in meals can help increase fibre intake in a balanced way.

Possible Side Effects Of Increasing Fibre Intake

As beta-glucan is a form of fibre, increasing intake too quickly can cause mild digestive discomfort. Some people may experience bloating, wind, or constipation, especially in the early stages. These symptoms can often be reduced by staying physically active and drinking enough fluids throughout the day.

If you are concerned about how fibre affects your body, it is advisable to speak with your GP or a qualified health professional. They can offer guidance tailored to your needs. More information on increasing fibre intake and its health benefits is also available on the NHS website.

While the World Health Organization recommends 5g or a tablespoon of salt every day, Indians consume more than double, increasing their risk of having a fatal stroke exponentially.

According to EatRightIndia, Indians consume about 11g of salt each day through meals which can significantly increase their risk of high blood pressure, strokes and hypertension.

Hypertension causes over 1.6 million deaths annually, accounting for nearly 18 percent of all fatalities and heavily contributes to deaths caused by heart disease, stroke and kidney disease.

What Is Excessive Salt Dangerous?

The most important side effect of consuming excessive salt intake is high blood pressure. Salt causes the body to retain water, increasing the volume of blood in your vessels and leading to elevated pressure levels. If your blood pressure consistently measures over 140/90 mmHg, it's time to evaluate your salt consumption.

Over time, this can rapidly raise your risk for heart disease, stroke while also potentially contributing to stomach cancer and weakened bones. Additionally, high blood pressure damages kidneys and excess sodium can lead to kidney stones or disease.

Apart from a 5gm recommendation for adults, NHS suggests that children between seven to 11 years of age should not eat more than 5g of salt while those between four to six years of age should eat less than 3g of salt every day to maintain heart health.

How Can You Reduce Your Salt Consumption?

Both excessive and insufficient salt intake have been linked to adverse outcomes. Achieving the right balance is critical, and the best approach is to minimize processed food consumption rather than relying solely on the salt shaker.

Common items such as pickles, paapads, chutneys, salads and buttermilk significantly contribute to daily salt consumption. Hidden salts in packaged goods like biscuits, sauces, condiments and snacks also can increase your salt intake.

To cut down on your salt intake, experts recommend:

• Not adding salt in rice and dough for chapati, poori and paratha.
• Not sprinkling salt on salad, cut fruits, cooked vegetables or curd.
• Gradually reducing the salt usage while cooking from lesser to least.
• Limit food accompaniments like salted butter, salty spice mixes (chaat masala, jal jeera masala etc.), chutneys, pickles, ketchups, sauces and dressings as they contain excess salt.
• Baking soda, baking powder, and monosodium glutamate (MSG) also contains high sodium and should be avoided in your daily cooking.
• Not keeping salt on the table.
• Buying tinned vegetables, pulses or fish in water instead of brine.
• Being aware that some dissolvable tablets, such as painkillers, vitamins or prescription medicines, may be high in salt.
