            <h3>올바른 식생활 지침</h3>

            <h4>제때에</h4>

            <p>신체리듬에 맞춰 규칙적으로 식사하는 것은 아주 중요합니다. 특히 아침을 거르지 맙시다.</p>

            <h4>골고루</h4>

            <p>다양한 식품을 선택해 부족한 영양소가 없도록 해야 합니다.</p>

            <h4>알맞게</h4>

            <p>표준 체중을 유지하기 위해 하루에 필요한 적정열량을 섭취하는 것은 비만과 성인병을 예방하는 기본 노력입니다.</p>

            <h4>싱겁게</h4>

            <p>소금의 과잉 섭취는 고혈압을 비롯한 순환기계질환의 중요 요인이 됩니다. 건강을 위해 소금 섭취를 하루에 5g이하로 줄입시다.</p>

            <h4>즐겁게</h4>

            <p class="last">식사는 가능한 여럿이 함께 하는 것이 좋습니다. 가족끼리 즐겁게 하는 식사는 그 자체가 즐거움이고, 성인병 관리입니다.</p>
