When guidelines say that you should have 37 grams of sugar per day, does that just mean added sugar or does it include natural sugar as well?
Added sugar.
> The AHA suggests an added-sugar limit of no more than 100 calories per day (about 6 teaspoons or 24 grams of sugar) for most women and no more than 150 calories per day (about 9 teaspoons or 36 grams of sugar) for most men.

It’s gonna be added sugar. And it’s difficult to put a hard number on it as it totally depends upon your daily caloric intake and your current health. A good rule of thumb that I personally like to follow, this was said by Alan Aragon if you’re familiar with him. Very well respected nutrition guy in the evidence based fitness industry. He says do not exceed anymore than 10% of your caloric intake in added sugars
So if you’re intaking 1500 cals, do not exceed 150 cals of ADDED sugar which is about 35-40g. The reason for this is that one can still reach their fiber and micronutrient goal by sticking to that rule. Once you start going above 10% it starts to become extremely difficult to make room for fiber/micros. Because it’s not the added sugar in of itself that is so unhealthy, it’s the fact that it often leads to an excess of cals and falling short on one’s fiber/micros
Fun Fact about Sugar:
It’s added sugar. Carbs is just a fancy word for sugar and you should for sure be eating more than 37g of carbohydrates. What you want to avoid is added sugar and processed sugar. Some even suggest as low as 20 grams/day but it’s individual based on total calories. But I do recommend eating as little added sugar as possible.
