Why quit? Calorie-rich food containing MSG (monosodium glutamate), artificial flavors, sweeteners/sugar and preservatives are considered junk food. Aside from the weight gain these bring, MSG causes headache, dizziness, sleep disturbance, vomiting, and nausea.
MSG also contributes to water retention since it is high in sodium. Artificial sweeteners have their own effects on both the mom and the baby, such as bladder and placental problems; in extreme cases, these artificial sweeteners may cause mental disabilities in the baby.
How to quit? Clear your pantry of all junk food. Stock up on crackers or natural/organic potato chips that are low in fat and sodium. Snack on bite-size fruits and yogurt. Another way is to figure out what is more important to you—eating a larger portion of the reduced-fat version or eating a smaller amount of the full-fat version.
