People who don't regularly drink caffeine tend to be more sensitive to its negative effects. Other factors may include genetics, body mass, age, medication use and health conditions, such as anxiety disorders.
Most adults need seven to eight hours of sleep each night. But caffeine, even in the afternoon, can interfere with this much-needed sleep. Chronically losing sleep — whether it's from work, travel, stress or too much caffeine — results in sleep deprivation. Sleep loss is cumulative, and even small nightly decreases can add up and disturb your daytime alertness and performance.
Using caffeine to mask sleep deprivation can create an unwelcome cycle. For example, you may drink caffeinated beverages because you have trouble staying awake during the day. But the caffeine keeps you from falling asleep at night, shortening the length of time you sleep. Whether it's for one of the reasons above — or because you want to trim your spending on coffee drinks — cutting back on caffeine can be challenging. An abrupt decrease in caffeine may cause withdrawal symptoms, such as headaches, fatigue, irritability and difficulty focusing on tasks.
Fortunately, these symptoms are usually mild and resolve after a few days. If you're like most adults, caffeine is a part of your daily routine. And most often it doesn't pose a health problem.

Dietary Guidelines also recommend children consume specified amounts of seafood per week in ounces per week based on their calorie needs. In developing this chart, FDA and EPA considered the calorie need ranges that the Dietary Guidelines estimate for each age group and the amount of seafood consumption that the Dietary Guidelines recommend at different calorie levels.
For example, for children ages 4 to 8 years, the Dietary Guidelines estimate that to maintain calorie balance females need between and calories per day and males need between and calories per day, depending on whether they are sedentary or physically active.
For individuals with a calorie level of 1, per day, Dietary Guidelines recommend consumption of 4 ounces of seafood per week. For individuals with a calorie level of 2, per day, Dietary Guidelines recommend 8 ounces of seafood consumption per week. Therefore, the recommended fish consumption per week for the year-old age group ranges from 4 oz per week based on calories for sedentary females to 8 oz per week based on calories for active males.
