How much water should you drink in a day?
How much water do you need?
Every day you lose water through your breath, perspiration, urine and bowel movements. For your body to function properly, you must replenish its water supply by consuming beverages and foods that contain water.
So how much fluid does the average, healthy adult living in a temperate climate need? The Institute of Medicine determined that an adequate intake (AI) for men is roughly 3 liters (about 13 cups) of total beverages a day. The AI for women is 2.2 liters (about 9 cups) of total beverages a day.
What about the advice to drink eight glasses a day?
Everyone has heard the advice, “Drink eight 8-ounce glasses of water a day.” That’s about 1.9 liters, which isn’t that different from the Institute of Medicine recommendations. Although the “8 by 8″ rule isn’t supported by hard evidence, it remains popular because it’s easy to remember. Just keep in mind that the rule should be reframed as: “Drink at least eight 8-ounce glasses of fluid a day,” because all fluids count toward the daily total.
The healthiest fast food lunch option
#1 Panera Bread
Over 1,230 locations nationwide (and in Canada)
This bakery-cafe-based eatery wowed our judges with a comprehensive menu of healthy choices for every meal. “Variety makes it easy for everyone to choose healthy,” praises registered dietitian and panelist Marisa Moore. What does that mean for you? For starters, you can pick from two whole-grain breads for your sandwich and have an apple with it instead of chips (though the chips are fine, too—they can be baked!). Half-size soups, salads, and sandwiches make it a cinch to control portion size. Also, most of the chicken is antibiotic- and hormone-free, a rarity for large chains.
Panera also won top honors for kid fare, dishing out RD-approved crowd-pleasers like squeezable organic yogurt, PB&J (with all-natural peanut butter), and grilled organic cheese on white whole-grain bread.
We love: Delicious, nutrient-packed combos like a half–Turkey Artichoke on focaccia bread with a bowl of black bean or garden vegetable soup.
Danger zone: Sticky buns and cheese danishes are on display at the counter.

The importance of omega-3 fatty acids
Omega-3 fatty acids are essential nutrients for health. We need omega-3 fatty acids for numerous body functions, such as building cell membranes in the brain, and since our bodies cannot make omega-3 fats, we must get them through food. Omega-3 fatty acids are also associated with many health benefits, including protection against heart disease and possibly stroke. New studies are identifying potential benefits for a wide range of conditions including cancer, inflammatory bowel disease, and other autoimmune diseases such as lupus and rheumatoid arthritis.
There are two major types of omega-3 fatty acids in our diets: One type is alpha-linolenic acid (ALA), which is found in some vegetable oils, such as soybean, rapeseed (canola), and flaxseed, and in walnuts. ALA is also found in some green vegetables, such as Brussels sprouts, kale, spinach, and salad greens. The other type, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), is found in fatty fish. The body partially converts ALA to EPA and DHA.
We do not know whether vegetable or fish omega-3 fatty acids are equally beneficial, although both seem to be beneficial. Unfortunately, most Americans do not get enough of either type. For good health, you should aim to get at least one rich source of omega-3 fatty acids in your diet every day. This could be through a serving of fatty fish (such as salmon), a tablespoon of canola or soybean oil in salad dressing or in cooking, or a handful of walnuts or ground flaxseed mixed into your morning oatmeal.
