Lately I've been looking at how much fructose I eat daily, all of which comes from fruits and vegetables. I've decided to cut back on fruit consumption for a bit. But I am also looking critically towards the vegetables and tomatoes. I like tomatoes but they are technically a fruit (although legally a vegetable) and are considered 'high fructose' by many. I am reading that 1 cup of fresh chopped tomato has 2.5 grams of fructose. And onions have 2.6 grams of fructose per cup (not sure if this is pre or post cooking) Is this considered a lot? What is a good cutoff for amount of grams of fructose per day? I have heard some suggest 4 grams per day as a good number to stay under.
I know lifestyle and goals are going to influence any recommendations. I am curious both from a general scientific standpoint as well as from a personal one. My main goal right now is health and to continue feeling healthy. Paleo (plus magnesium pills) has made me feel probably the healthiest I have ever felt. However, I wouldn't mind losing a few more pounds and so I am experimenting with different macronutrient profiles to see what feels best. On the flipside I feel rather happy now and most of my experimentation is more due to curiosity than anything else. Activitywise, I spend a large portion of each workday walking around. I also like to hike in the mountains about once per week. And erratically I go to the gym and lift weights. So I would say I lead a moderately active lifestyle.
