One of the major problems with artificial sweeteners is that they constantly stroke your cravings for sweetened foods and drinks. But there are more serious drawbacks to aspartame.
Aspartame has been linked to a variety of health problems including birth defects, diabetes, emotional disorders, epilepsy or seizures and migraines. Recent research from Japan has indicated that very low doses reduce sperm count quite considerably in mice. Artificial sweeteners are one of the worst things you can put in your body.
Sugar itself contributes to diabetes, obesity, heart disease and probably cancer, and artificial sweeteners aren’t much better. If you are addicted to eating something sweet, my advice is to wean yourself off both sugar and artificial sweeteners, and sweeten cereal and desserts with fruit instead for example. One great way to reduce your cravings for sugar (and I can vouch for this) is to add sweet vegetables to your diet. Most people report having cravings in the afternoon so you must make sure that you've eaten well throughout the day to avoid this...Add reasonable portions of foods like carrots, pumpkin, sweet potato and beetroot to your meals and you’ll find your cravings and sweet tooth will disappear in no time!
