Lime's Citrate May Lower Kidney-Stone Risk

Lime (Manao) · มะนาว · Citrus aurantiifolia

Lime (Manao) — มะนาว (ma-nao) — Citrus aurantiifolia.

Lime — mah-nao. Lime's citrate raises urinary citrate and may lower kidney-stone recurrence. The edible part is the fruit, and it's rich in vitamin C. Tom Yum Goong boils a hot and sour shrimp broth, heavily squeezed with fresh lime juice off the heat so the citrus doesn't turn bitter. Pla Kapong Neung Manao drenches a whole steamed barramundi in a fiery, garlic-packed lime broth that you soak up with warm jasmine rice. How to use lime in Thai cooking: both the juice and the zest, whose aromatic peel carries prized flavorful oils. Lime's vitamin C helps your body absorb the iron from beans and greens when you eat them together. Lime juice on your skin plus sunlight can cause a blistering burn, so wash your hands before heading out in the sun.

Narration transcript

Opening

Lime — มะนาว, ma-now. This is the small, thin-skinned manao that sours nearly every Thai plate, its juice squeezed in off the heat so it never turns bitter. You use the whole fruit — the sharp juice and the fragrant oil in the zest. A hard squeeze finishes tom yum and steamed fish.

Tom Yum Goong (ต้มยำกุ้ง)

Tom yum goong is a hot and sour Thai shrimp soup seasoned with fresh lime juice off the heat, traditionally served with a side of steamed jasmine rice.

Pla Kapong Neung Manao (ปลากะพงนึ่งมะนาว)

Pla kapong neung manao is steamed barramundi drenched in a fiery lime and garlic broth, classically paired with warm jasmine rice to absorb the soup.

Nutrition summary

No surprise for a citrus — the whole lime is a good source of vitamin C, with a little fiber and copper.

Vitamin C

Vitamin C is used to build collagen and helps protect cells from oxidative stress.

Closing

Here's the odd one: lime juice on your skin plus strong sun can raise a blistering burn, so rinse your hands before you head outdoors. Container limes fruit hardest if you hold back water for two weeks, then soak them — the brief drought triggers a flush of flowers. Follow Longevity Biome, and LIKE this video for regular updates.
