Intake valves allow air/fuel mixture into an engine’s cylinders for compression and combustion. Two valves are used in each cylinder, with the exhaust valve driving air out. Improper valve function can decrease power and gas mileage. The most common type of intake valve is the poppet valve, which can be located at the top or […]
Ram air intake systems force outside air into the engine, increasing horsepower in high-performance vehicles. The system captures airflow through a scoop on the hood or front of the car, and is also used in motorcycles and off-road vehicles. It was introduced in the 1960s and is often combined with supercharger systems in drag racing […]
Religious dietary restrictions are observed by followers of various religions, often for food safety or religious beliefs.

Some world religions have dietary restrictions which are observed by their followers as […]
A cold air intake system draws cold air from outside the engine compartment, generating more power with minimal cost. Aftermarket systems use a free breathing air filter and a better location for the flow of cooler air. The factory offers a cold air intake kit for vehicle owners to improve performance. A cold air intake […]
Americans consume too much sodium, with an average of 3,466 mg per day, exceeding the recommended levels of 2,300 mg for young, healthy people. Processed and fast foods account for 77% of sodium intake, and high blood pressure affects 90% of Americans. Older adults and African Americans should consume less than 1,500 mg per day. […]
Carbohydrates are the body’s primary source of energy and should account for 45-65% of total calorie intake. The recommended daily intake varies based on factors such as age, weight, and activity level. The RDA is the minimum amount needed to meet nutrient requirements for healthy individuals. The recommended daily intake of carbohydrates refers to the […]

Cutting calories should not exceed 500 per day, and eating fewer than 1,200 calories per day can damage vital organs. Lifestyle changes are difficult, but making […]
Recommended daily intake (RDI) is the amount of nutrients a person should consume daily. RDIs are calculated for macronutrients, micronutrients, and calories. Percent daily values on nutrition labels help consumers assess nutrient density. RDIs are recommendations, not absolute answers. The recommended daily intake suggests the amount of a given nutrient that a person should consume […]
Recommended daily intake (RDI) is the amount of nutrients a person should consume in a day, including macro and micronutrients and total calories. RDI is used to determine the percentage of daily values on nutrition labels. Reference Daily Intake and Recommended Daily Value refer to the same calculations as RDI. Percent Daily Values on nutrition […]
Protein is essential for building cells, regulating enzymes and hormones, maintaining fluid balance, and creating energy. However, too much protein can cause health problems such as liver and kidney damage, osteoporosis, heart disease, cancer, and kidney stones. The body generally uses carbohydrates and fats for energy, not protein. Eating protein is essential for human health […]
A study by Tufts University found a positive correlation between high fat intake and macular degeneration. Diets high in trans fats, such as baked goods and dairy, were found to be particularly harmful. However, there is no connection between macular degeneration and the intake of “good” fats, such as omega-3 fatty acids. A detailed, large-scale […]
Caffeine consumption varies by country, with coffee being the main source in the US and Canada, while tea is the main source in the UK.

The Dietary Reference Intake is a program of nutritional recommendations consisting of four values for each nutrient. Adequate intake is a recommended daily intake level assumed to be satisfactory for most people, while Tolerable Upper Intake Levels warn against excessive supplementation. The adequate intake is a specific component of the dietary reference intake. Initiated in […]
Consuming too much fiber can cause diarrhea, malnutrition, dehydration, stomach cramps, and bloating. Dietitians recommend 15-30 grams of fiber daily, and more than 50 grams is considered too much. Fiber can prevent disease, detoxify the body, and lower cholesterol and blood sugar. Whole foods are unlikely to cause excessive fiber intake, but fiber supplements can […]
Many people don’t consume enough fiber, which is necessary for digestion, disease prevention, and weight loss. Experts recommend 20-30 grams per day, but many only consume 11 grams. Eating fruits, vegetables, nuts, legumes, and whole grains can help increase fiber intake and reduce the risk of heart disease and certain types of cancer. Many people […]
Controlling food intake is crucial for maintaining optimal health, preventing obesity and related health problems, ensuring proper nutrition for babies and children, managing medical conditions like diabetes and hypertension, and promoting psychological well-being. It is important to follow nutritional guidelines and monitor food intake during pregnancy. Controlling food intake is important for many reasons, primarily […]
There is no single number or percentage for healthy daily fat intake, as it depends on factors such as age, weight, and activity level. Saturated fats should be limited, while monounsaturated fats are recommended. The general recommendation is that fat should not exceed 30% of daily calories, but this may need to be reduced for […]
Excess protein can lead to increased production of urea in the urine, causing negative side effects such as kidney disease, gout, dehydration, and increased risk of osteoporosis and kidney stones. The liver converts excess protein into other usable molecules, and the kidneys are responsible for excreting urea. Those with kidney disease should keep their protein […]
