肉類，更準確地用生物學的方式說，「肌肉」，是組成一餐均衡生鮮餐食的主要食材。
其中包括了「不帶骨肉類、脂肪、舌頭、心臟、胃、肺、胗、各式軟骨及筋」都可以稱得上是肌肉
犬貓需要大量的蛋白質來維持身體機能，且他們需要從餐食中的肌肉取得身體所需的熱量及氨基酸
生鮮餐食中，肌肉的組成約佔60~80%，這些肉類不但提供蛋白質還提供了必需的營養素，包含「水溶性維生素」及「礦物質」
肉類根據肌肉纖維分成兩大類：「慢縮肌纖維」及「快縮肌纖維」
慢縮肌纖維包含大多數的紅肉，例如：牛肉、羊肉、鴨肉、豬肉、鹿肉。這類的肌肉有攜帶氧氣的功能、含有較高的肌紅素及血紅素，因此呈現的顏色較為鮮紅
快縮肌纖維則包含大多數的白肉，例如：雞肉、火雞、兔肉、鵪鶉。這類肌肉含有較少的肌紅素，因此呈現的顏色較不鮮豔
簡單來說，紅肉較白肉來得更加營養且含有更高密度的蛋白質、維生素、礦物質及氨基酸
提供毛孩多樣化的肉類，才能確保毛孩的營養是最多元且均衡的
“Muscle meat” according to biology definitions include boneless muscle meat, raw animal fat, tongue, heart, green tripe, lungs and gizzards
Cats and dogs require a large amount of protein and amino acids for optimal health. A raw diet that includes 60~80% muscle meat provides not only protein but also many essential nutrients such as water-soluble vitamins and minerals
Muscle meat is categorized into red meat and white meat based on the type of muscle tissue fibre
Slow twitch muscle fibres aka red meat, for example: beef, lamb, duck, pork and game meat. Slow twitch muscle fibres have a higher amount of myoglobin therefore red meat is usually darker in colour
Fast twitch muscle fibres are white meat, for example: chicken, quail, turkey and rabbit.
White meat muscle has a lower level of myoglobin therefore it shows a lighter colour
Simply put, red meat is more nutrient dense compared to white meat and it gives a higher concentration of protein, vitamins, minerals and amino acids
Feed your furry friends a variety of meat to ensure they are nutritionally complete and balanced
