How much water should you drink in a day?

Ah, water. The age old question is how much should I drink in a day? We all have picked up beliefs about how much water we need. We see people carrying around gallons of water. We are always told water is the key to weight loss and digestive health. So when this topic came up in my biochemistry class, I decided to share the info like I promised I would in this section of my blog.

Water makes up about 60% of our body weight.

And since water recommendations vary with age, gender and physical activity an “adequate intake” is recommended. That adequate intake recommendation is 2.7 liters or 90 oz for women. And 3.7 liters or 123 oz. for men. So how many cups is that? That’s 11.25 cups for women and 15.375 cups for men. (mom, check my math)

Now what does that actually mean in terms of standard water bottles? For us gals, over five standard 16.9 Fl. oz water bottles a day and for the men, over seven.

So are you drinking enough? I for sure am NOT but just knowing this information helped me up my intake. I hope it does the same for you.

If you struggle to polish off those Poland Spring bottles think of eating more fruits and vegetables which are high in water. 75-80% of our daily water intake comes from beverages. 20-25% comes from food, like nuts, seeds, fruits and vegetables. Obviously, watermelon. And a small amount, is created from cellular metabolic reactions.

. But here’s the bottom line, I think we just need to drink more water. And like me, if you were drawn to this article because you googled, “how much water should I drink?” then you probably aren’t drinking enough. Does it suck to pee every 35 seconds? Yes. I think we can all agree on that but the benefits of drinking more water far outweigh the total toilet time.

Vitamin B3: Building a case for peanut butter.

Ah, is there anything better than peanut butter? In my mind, no. I love it and even though I feel like it’s been pushed to the side over the years as other nut butters have burst onto the scene, I have continued to stay loyal.

In class this week we were going through the B Complex Vitamins and we got to Vitamin B3 (otherwise known as Niacin). The RDA for this vitamin is, 14 mg a day for woman and 16 mg a day for men. Well guess what, in looking over the food sources of Vitamin B3 (Niacin), low and behold, 2 tablespoons of peanut butter is listed as a good source containing 4.3 mg. When I fact checked that with the Extra Crunchy Skippy Jar I have at my desk, I saw that it contained 3.2 mg (so pretty close). That’s 20% of your Daily Value.

And even though it may make sense to eat a food source that’s closer to the RDA many of those sources aren’t as readily available daily and/or may not appeal to our taste buds. Tuna, Swordfish, Salmon, Halibut & Beef are among the top sources, things I don’t eat. Hence, why I focused on peanut butter.

And since we’re talking about this fun vitamin, listen to this, when you eat protein, an amino acid in the protein called tryptophan, you know the word that’s always associated with turkey and thanksgiving? that actually synthesizes to Niacin in the body. So you can eat Niacin and make Niacin. About 60 mg of tryptophan generates 1 mg of Niacin. And every 1 gram of complete protein has about 10 mg of tryptophan. So to overly simplify that, let’s just say 1 oz of chicken contains 6 grams of protein. That 1 oz will generate 1 mg of Niacin Equivalent.

So you have some peanut butter and some complete protein and you’re on your way to satisfying your bodies need for Niacin (Vitamin B3)

And why should you care about Niacin? Because it is important for energy metabolism. Yey Metabolism!
