California has been hit by an unusually bad cold snap this year and the effects of the freezing weather have really taken a toll on crops - and the bad weather isn't even over yet. Some estimates say that at least 75% of the citrus crop has been destroyed and others say even more, drawing from the more than 80% that was ruined the last time the state suffered a severe cold snap. The weather is so bad that Governor Arnold Schwarzenegger declared a state of emergency in the 10 agricultural counties that have been hardest hit by the weather.

86% of the lemons and 21% of all the oranges sold in the US are grown in California, which makes it the largest citrus-producing state in the country. The loss of crops is devastating to the farmers, but it will also hit consumers hard at the grocery store. Orange and lemon prices are already increasing and the wholesale price has more than doubled in the last seven days alone. Juice prices will increase as well. "The price spike is expected to hit supermarkets in the next two weeks, when the present inventory dwindles."

While citrus is taking the biggest hit, basically every winter crop in California has been damaged, from avocados to lettuce, and consumers across the country will feel the effects of doubling and tripling prices in the produce department, especially if they want to buy US-grown fruits and vegetables.

Easy meal prep is hot right now. By this, I am referring to the make-and-freeze dinner businesses that are thriving all across the US. With names like Dream Dinners, Super Suppers, My Girlfriend's Kitchen, Supper Thyme USA, What's for Dinner and Dinner by Design, all appeal to the "busy family demographic, where people want to have home cooked meals but don't necessarily feel that they have the time to do it themselves. These businesses offer kitchens with lots of partially assembled meals and ingredients that you can put together in combinations that your family will like. Typically, meals are prepared for a week or two in advance and everything can be frozen. Heating instructions (and any other cooking suggestions, if needed, are included.

The trend is so popular that it is starting to spread out of the US. In London, a chain called Dinners Made is springing up and gaining popularity with those who are looking for food to make in advance and freeze, and also with those who want to entertain and don't have time (or perhaps the ability) to cook everything from scratch without some assistance. Using Dinners Made means that the recipes are included, prep is done and cleanup is taken care of, as they are at every similar easy meal prep shop. Combining the convenience of working in the store with below-restaurant prices, a flexible menu and fresh ingredients, it's not hard to see why the idea is spreading so rapidly.

Frozen foods were once a technological wonder, but are now often the butt of food jokes, grouped together with fast food as unhealthy substitute for "real" food that is rarely worth eating. But frozen dinners are quick and convenient, though sometimes grouped with fast food on people's "do not eat" lists, they frequently present a healthier alternative to it when you really need something that doesn't require much preparation. There are also so many new frozen food products on the market every year, all made with technology that permits a wider range of textures in the final dish, that even staunch from-scratch cooks might be tempted by some of the organic, all-natural options in the freezer case. Besides, you're not the only one eating them. More than $25 billion of frozen foods were sold last year, peaking in January with the sale of diet-oriented foods. Here are a few more frozen food facts:

• 53% of all American households use frozen dinners at some point.
• They are most popular with 18-24 year olds, those over 75 and single people. Roughly 400 new frozen-food products, from toaster waffles to turkey dinners, are introduced each year by more than 300 companies.
• Despite the fact that they are so popular with singles, there are more 2-person and family-sized meals available than ever before to get in on the "busy family" market.
• Mexican frozen food is extremely popular right now, whether for breakfast, lunch or dinner.

Ice cream headaches, a.k.a. brain freeze, are caused when quickly-eaten cold foods come into contact with the roof your mouth. Since the mouth doesn't have time to warm up when eating or drinking quickly, the nerve center there panics and sends signals to your brain that indicate the body is freezing. Blood rushes to the brain and the eater feels a sharp, stabbing type of pain that lasts anywhere from 30-60 seconds in most people.

Strangely, ice cream is the most commonly cited cause for head pain, but it can be avoided easily. Most people feel that positioning the cold foods at the sides of your mouth will prevent brain freeze. This allows the food to warm up slightly before coming into contact with the roof of your mouth. If you're drinking something frozen, like a smoothie, don't aim the straw directly at the roof of your mouth, either. The other "cure" is simply to eat more slowly.
