While too many calories can contribute to weight gain, hormones matter more. And overall, healthy dietary fat positively impacts hormones that regulate satiety and appetite. Some dietary fats — including saturated fat — are s till hotly debated. Likewise, omega-3 fatty acids get classified as good while omega-6 fatty acids are bad.
Additionally, many healthy foods including nuts and seeds contain omega-6 fatty acids. Many of us simply eat too many omega-6 fatty acids — about 20 times more, in fact — and not enough anti-inflammatory omega-3 fatty acids. The one dietary fat nearly everyone agrees is bad: Trans fats. Your body can synthesize vitamin D from sunlight, and gut bacteria produce some vitamin K, but for the most part, you need to get vitamins from food or supplements.
The 13 known vitamins fall into two categories: Water-soluble or fat-soluble. The body cannot store water-soluble vitamins, which quickly excrete in your urine and need to be replaced more often than fat-soluble vitamins. When you read a food or supplement label, the nutrient breakdown will typically be clear as to amounts of specific vitamins. Deficiencies in any specific vitamin can create widespread problems that span from mild to life-threatening.
Most vitamin recommendations come largely from guidelines set by the Institute of Medicine, which typically recommends amounts in milligrams mg , micrograms mcg , or until recently international units IU. Some experts believe these vitamins recommendations are too low, making supplementing necessary. Even with a healthy diet, cooking, storage, and exposure to air can deactivate these fragile compounds. While both are micronutrients, vitamins, and minerals differ in that minerals are inorganic and hold onto their chemical structure.
Like vitamins, minerals support numerous bodily functions, including building and maintaining healthy bones and teeth, supporting muscle function, optimizing immunity, and energy production. Mineral deficiencies can create widespread problems. Take magnesium, which plays a role in over enzyme systems, including protein synthesis, muscle, and nerve function, controlling blood glucose, and regulating blood pressure.
Like vitamins, minerals interact with each other. Too much of one mineral can create imbalances in another. Too much manganese, for instance, can trigger iron deficiencies. Note: Consider conferring with a healthcare practitioner before using larger amounts of individual nutrients.
You can survive for weeks without food, but water? While some experts speculate up to a week, 3 or 4 days might be more accurate. But the top organ? Sufficient water intake becomes vital for nearly every bodily function. Your body constantly loses water via sweat, urinating, and even breathing. Dehydration can occur more easily than you might imagine, and its repercussions can jeopardize your health and even become fatal.
How much water you require depends on numerous factors including age, gender, health status, and physical performance.
The average adult man needs about 3 liters per day, whereas an adult female needs about 2. Emphasis on clean and filtered. A good rule of thumb is half your body weight in water ounces every day. Keep a BPA-free canteen nearby filled throughout the day to meet that quota. There are some exceptions, such as taking amino acids like L-glutamine therapeutically or consuming protein powder.
Instead, we usually consume nutrients together in food and supplements. Water is absolutely crucial for every system in your body. About 62 percent of your body weight is water. Water improves your brain function and mood. It acts a shock absorber and a lubricant in the body.
It also helps flush out toxins, carry nutrients to cells, hydrate the body, and prevent constipation. Even mild dehydration can make you feel tired and impair your concentration and physical performance. Fruits and vegetables can also be a great source. Munch on some spinach or watermelon to stay hydrated. Eating a varied diet full of fruits, vegetables, healthy proteins and fats, and whole grains is the best way to get enough of these six essential nutrients plus the important category of phytonutrients — the beneficial chemicals in colorful plants that prevent disease.
