项目编号：BS-Python-044
一，环境介绍
语言环境：Python3.8
数据库：Mysql: mysql5.7
WEB框架：Django
开发工具：IDEA或PyCharm
二，项目简介
基于Python和Flask框架实现的膳食健康管理系统是一个旨在帮助用户管理日常饮食、提升健康水平的Web应用。该系统通过用户友好的界面，允许用户记录每日摄入的食物种类、数量及营养成分，同时根据用户的健康目标（如减肥、增肌、维持健康等）提供个性化的膳食建议和营养分析。系统后端采用Flask框架构建RESTful API，处理数据请求与响应，确保数据的安全性和高效性。前端则可能采用HTML/CSS/JavaScript等技术，实现动态交互和美观的页面展示。此外，系统还集成了数据库（如SQLite、MySQL等）来存储用户信息和膳食数据，支持数据持久化和查询分析。通过这一系统，用户能够更科学地规划饮食，实现健康生活的目标。
三，系统展示
后台管理系统
