Spinach also contains oxalic acid, which inhibits the absorption of iron by the body. The availability of iron in spinach is increased if it is eaten with foods rich in vitamin C and calcium, so mixing it with citrus juice or dairy makes it more nutritious.
All winter, the northern hemisphere has been tilted slightly away from the sun. As summer approaches, the tilt changes so the north half of the planet tilts slightly towards the sun. The equinox occurs when Earth’s tilt is neither toward nor away from the sun.
Eggplant seeds are relatively slow to germinate, and will probably take 10 days or longer. Soil heated from beneath is likely to speed germination and help young plants develop. Aim for around 27°C (just over 80°F). Sow indoors as long as 12 weeks before the last frost to give them a really good head start.
There are some very interesting facts about tomatoes. No one can say for certain, but the ancestor of all modern tomato varieties appears to have been a scrambling vine that was native to the highlands of Peru. Archaeological evidence suggests that these wild plants were harvested for their small green berries. The first domestication of the tomato was by the Aztec people of central Mexico who grew it for its small, cherry-sized yellow fruits. They gave it the name Xitomatl (swelling fruit), from which we get the modern English word, “tomato.” Both of the explorers Cortes and Columbus are credited...
Many varieties of maize are grown for dried, fully mature seed, which is eaten as a grain, but sweet corn is picked before the seeds mature fully, before its sugars convert back into starch. This is why fresh corn must be eaten fairly quickly after harvest, before it degrades and becomes starchy.
